When your engine suddenly shuts off, the road transforms from routine to risk in seconds. Understanding why this happens can save your car and your safety. So what triggers these unexpected failures?
If the fuel filter, pump, injectors, or fuel lines become clogged, the amount of fuel reaching the engine becomes insufficient, leading to sudden engine shutdown.
One of the most common and straightforward reasons for a car to stop while driving.
When these components fail, the combustion process inside the engine cannot be completed, causing the vehicle to stop.
Accumulated dust and debris reduce the amount of oxygen needed for combustion, which may cause the engine to stall.
A failing battery may not provide the necessary power to operate essential vehicle components, resulting in engine shutdown while driving.
When the engine temperature exceeds the normal range, it may shut down suddenly. This is a serious issue that can threaten the safety of the vehicle and its occupants.
When the AC is turned on, the system requires additional power to operate the compressor and fan. If the battery is weak, it may not handle the extra load, causing the engine to stall.
If the alternator is not charging the battery efficiently, the vehicle may experience a power shortage, leading to engine shutdown.
Problems such as low refrigerant pressure or compressor malfunction increase the load on the engine, which may cause it to stop.
Turning on the AC increases engine load. If the cooling system is weak, the temperature may rise abnormally, causing the engine to shut off.
A clogged fuel filter or weak fuel pump may fail to supply enough fuel. When the AC is activated, fuel consumption increases, potentially causing the engine to stall.

A Mojaz report helps you read a used car’s history through the records available; it does not deliver a final verdict on its condition. Start by matching the vehicle’s identity, then read mileage, accident and maintenance records chronologically and compare them with documents and the car’s current condition. No accident record does not mean accident-free, and missing mileage readings do not validate the odometer. Use the report to identify seller questions and professional inspection priorities before deciding to buy, not as a replacement for inspection.
The official Mojaz homepage (in Arabic) says it brings together key historical vehicle data from official sources in one report. Its report outline lists vehicle information, odometer reading history, accident records, maintenance and repairs, warranty information, spare parts, vehicle reputation and related images.
These are section names presented by the service, not a promise that every section contains data for every car. Read what is actually available, and do not turn a blank field into a positive or negative finding. Likewise, do not infer a specific rating or acceptance standard from the vehicle reputation heading; use any accompanying explanation and ask about unclear descriptions before relying on them.
Before discussing findings, establish that the report belongs to the actual car being offered. Ask to see the full version rather than a cropped image of a reassuring section, and match its identification details to the vehicle documents and the car. Do not rely on a similar colour or general description, or dismiss an identification mismatch as a minor error without checking.
For identification details and their locations, see the guide to vehicle identification numbers, while paying attention to the name of each identifier in the document you are reading.
Read the date of each distance reading, not just the last number. Put the available readings in order from oldest to newest, then compare the latest with the car’s odometer during the viewing. Check measurement units first; do not directly compare figures expressed in different units. Your aim is to understand the sequence and identify questions, not estimate true mileage from cabin appearance alone.
If the seller mentions an odometer replacement, ask for the work record and evidence of readings before and after replacement, if available. Do not fill a missing sequence with estimates or treat consistent readings alone as a guarantee that the entire usage history is known.
If an accident record appears, read its details as written and compare them with repair documents supplied by the seller. Do not reduce the assessment to a record count or label damage minor or severe without supporting information. A report may describe a historical event, while repair quality and present condition need an independent inspection.
If related images appear, check their connection to the event, the vehicle and their date whenever that information is available. A photograph does not reveal everything behind visible parts, and missing images do not rule out damage. Where structural repairs are suspected, request a specialist inspection. The guide to signs of bodywork and structural repairs can help you frame questions, not make your own technical verdict.
If no accident record appears, the accurate wording is: no event is visible in the data you are reading. Do not replace that with the car has never had an accident, or let that inference cancel the inspection or the request for repair documents.
Read available maintenance and repair entries with their dates, comparing them with the seller’s invoices. Distinguish a record of past work from proof that the relevant system works well today. If a repair description recurs, ask what was done and what happened afterwards, without automatically assuming a particular fault or an unsuccessful repair.
Warranty information alone does not mean cover is active or transferable to you; verify the document and terms with the relevant provider. Equally, do not infer from a spare parts section that every component is genuine or in good condition. A missing maintenance record does not prove neglect, but leaves a question requiring documents and inspection.
Compare documented work with the appropriate owner’s manual requirements alongside a professional. Do not derive a new servicing schedule from the report or assume one completed job means all other scheduled work was done or related components are sound.
Use this table to organise your notes; it is not a real sample vehicle report. Always distinguish what you read, what you still do not know and the next step needed to close that gap.
| What you read | What it does not prove alone | Next step |
| Consecutive odometer readings | Complete mileage history | Compare with the odometer and documents |
| No odometer readings | Accuracy of current mileage | Seek more evidence and document the gap |
| An accident record | Current repair quality | Repair documents and specialist inspection |
| No visible accident record | An accident-free car | Professional body and paint inspection |
| Recorded maintenance work | The component’s condition today | Compare with the current inspection |
| Warranty information | Active cover for the buyer | Verify terms with the relevant provider |
Start with an open question about the car’s usage history, then address unclear report entries. Request specific answers that can be connected to documents; personal trust or numerous photographs are not substitutes for verification. Keep your notes separate from the original report so your interpretations do not become confused with its records.
Give the professional your report and notes before inspection, and request an assessment of the current structure, mechanical and electrical systems and safety components. Do not simply seek confirmation of an existing impression: ask what was checked and what could not be verified. To organise the rest of the viewing, see the used car inspection tips before purchase.
If a material identity or mileage discrepancy appears, or a significant repair remains unexplained, postpone the decision until it is clarified. If the gap cannot be closed, treat it as unknown information rather than proof of sound condition. Once the technical assessment is settled, review the vehicle ownership transfer steps on Absher separately; a history report does not replace the sale procedures.
In short, read a Mojaz report as available evidence and open questions, not a certificate that the car has no defects. Match its identity, review the timeline and connect the findings with documents and an independent inspection. A stronger decision clearly distinguishes what is established from what remains unknown.

If you turn the key or press the start button and the engine does not turn over at all, the cause may lie in the car battery or its connections, in the starter motor and its circuit, or in a starting condition that has not been met, such as the gear position or key recognition. Whether it is a battery or starter problem usually shows in the dashboard lights, the type of sound and the result of a jump start test. These are indications for ordering the checks, while confirmation comes from a qualified technician with proper equipment.
A no-crank means the engine does not turn when you try to start it: you hear nothing, or only a click or rapid clicking. If the starter turns the engine at its usual sound but the engine does not fire, that is a different situation, usually caused by fuel, spark or sensors, which we cover in the guide on an engine that cranks but will not start. Here we focus on the first case, whose diagnosis starts with the electrical side.
Watch the moment of starting and the dashboard lights before and during it, as each sign has a more likely cause, not a final verdict:
For more detail on each side, see the signs of a failing starter motor and car battery failure symptoms and how to test them.
Fitting a new battery does not mean the problem is over; the old one may have been fine, or the cause may be somewhere that was never checked. The main possibilities are:
These checks do not require removing any part, and they help you narrow down the likely cause:
The table below summarises common signs, the more likely side and the suggested next step:
| Sign | More likely | Also worth ruling out | Next step |
| No sound, dashboard dark | Battery or terminals | Main fuse | Inspect the terminals by eye and try a jump start |
| No sound, dashboard bright | Starting circuit | Gear position, key and relay | Confirm P or N and the brake, and try the spare key |
| Single click, bright lights | Starter or solenoid | Starter cable or ground strap | Have the starter and its circuit tested |
| Rapid clicking, lights dim | Battery or terminals | Weak charging system | Try a jump start, then test the battery and charging |
| Slow, laboured cranking | Battery or connections | Starter drawing high current | Ask for a battery load test and a starter draw test |
| Whirring or grinding, no crank | Starter gear | Flywheel ring gear teeth | Stop trying and have it inspected |
| Intermittent problem | Loose connection or weakening starter | Relay or gear position sensor | Note when it happens and tell the technician |
A technician relies on measurement against the manufacturer’s data, and usually checks:
The starter motor is a small electric motor that draws its current from the battery and turns the engine at the moment of starting through a gear that meshes with the flywheel, then disengages once the engine runs, so it needs a healthy battery and good connections.
If the battery is charged and tested, the terminals are sound, and the single click with bright lights repeats even with a jump start, the starter or its circuit becomes more likely, and a technician confirms it by measuring voltage drop and current draw.
Rapid clicking usually happens when the starter does not receive enough current because of a weak battery or corroded or loose terminals, while a single click with bright lights may be linked to the starter or its solenoid.
The starter may work temporarily after being tapped, but that is a sign of a fault in it rather than a fix, and it is dangerous while someone else tries to start the car.
Yes. If the car does not recognise the key because of a weak key battery or a system fault, the starter may not turn or the engine may not fire, a message usually appears on the dashboard, and the owner’s manual may explain an alternative starting method.
When the car will not crank, note the dashboard lights, the type of sound and the result of a jump start: dim lights and rapid clicking lean towards the battery, while a single click with bright lights leans towards the starter, and do not forget the gear position and the key. Avoid risky shortcuts, and leave confirmation to a qualified technician.

Vehicle driving authorization on Absher is an electronic service that lets a vehicle owner add an authorized person to drive the vehicle inside or outside the Kingdom, depending on the type of authorization selected. The owner starts from Vehicles, then Manage Vehicles, selects the vehicle, chooses Authorize Vehicles and then Issue Authorization. Before that, the vehicle registration must be valid with active insurance, and both parties must have Absher accounts. This guide covers the conditions, steps, period limits, the difference from ownership transfer and what the owner should check first.
The official Issue an Authorization service page on the National Portal says the service allows you electronically to add an authorized person to drive a vehicle inside or outside the Kingdom, depending on the selected type of authorization. The service belongs to the Ministry of Interior, targets individuals, both citizens and residents, and lists its channels as the website portal and the iOS and Android apps.
The authorization is therefore permission to drive, not a sale or a transfer of ownership. The vehicle owner issues the authorization, and the authorized person is added to drive within the selected type and period. Read the service name in your account carefully and do not confuse it with other vehicle services in the same menu.
The Prerequisites tab of the official service page lists the following conditions, as shown at the time of writing:
The Required Documents tab lists the following:
The text we reviewed adds no other conditions, so follow what the service requests for your case rather than lists circulating in forums or messages.
The following steps come from the official service page. Menus may look different in the portal and the app, so look for the same names:
The page describes the service duration as immediate, but do not rely on pressing the issue button alone; review what the service displays after submission to confirm the transaction is complete. If a message prevents issuing the authorization, return to the conditions above and start with the item the message refers to, such as insurance validity or the validity of one of the licenses, instead of retrying without changing anything.
The page states that the authorization applies inside or outside the Kingdom depending on the type of authorization you select in the final step. Decide the purpose before you start: will the authorized person drive only inside the Kingdom, or do they need to drive the vehicle abroad?
For an external authorization, the Required Documents tab requires the authorized person to hold an exit and re-entry visa. The page links the visa duration to the authorization period, but the Prerequisites wording (the authorization period must not exceed the visa duration) runs in the opposite direction to the Required Documents wording (the visa must not exceed the authorization period), so follow what the service accepts for your case. A holder of a final exit visa cannot be added as an authorized person.
The service page does not address the requirements of other countries or border crossings when travelling by car, so ask the competent authorities about this before relying on the authorization alone.
The service page does not set a fixed authorization period; it sets upper limits instead. The period must not exceed the validity of the vehicle registration, the validity of the authorized person’s driving license, or the duration of their exit and re-entry visa if they hold one. In practice, whichever of these dates expires first limits the period you can choose.
As for cancellation, the pages we reviewed do not explain the steps. Start from the Authorize Vehicles screen in the owner’s account and review the options shown to you. If nothing fits your case, ask the official Ministry of Interior support channels, and do not rely on an unofficial explanation that mentions a specific button or period.
If the vehicle registration is about to expire, review the vehicle registration renewal steps on Absher before choosing the authorization period, because the period may not exceed the registration validity.
Some people confuse allowing someone to drive the car with selling it to them. As the service describes it, authorization adds an authorized driver and is issued by the vehicle owner, while ownership transfer is a separate procedure that changes the owner. The table summarises the difference:
| Item | Driving Authorization | Ownership Transfer |
| Purpose | Add an authorized person to drive the vehicle | Transfer vehicle ownership to another owner |
| Who starts it | The vehicle owner, according to the service page | According to the sale service conditions |
| Does the owner change? | The service describes no change of ownership | Yes, that is the purpose of the procedure |
| Period limits | Not beyond the registration and the authorized person’s driving license validity | Follows the transfer service conditions |
If your aim is to sell or buy the car, authorization is not a substitute for a sale; review the Absher ownership transfer steps and sale conditions to complete the correct procedure.
The official conditions determine whether the authorization can be issued, but they do not answer every practical question. Before issuing it, review the following points:
If an accident happens while the authorized person is driving, learn the steps to take after a car accident and Najm reporting. The service page does not address how responsibility for accidents or violations is shared between the owner and the authorized person, so do not build assumptions on it; ask the competent authority or your insurer about your case.
Yes. The Required Documents tab states that the authorizer must be the vehicle owner. The authorization is therefore not issued from the account of someone who does not own the vehicle, even if they usually drive it.
Yes. The page requires both the authorizer and the authorized person to have Absher accounts. Confirm this before starting so the process does not stop when you enter the details.
No. The prerequisites state that authorization cannot be granted to someone holding a final exit visa. For a holder of an exit and re-entry visa, the authorization period is tied to the visa duration.
The published condition is a valid vehicle registration with active insurance. If either has expired, resolve it first and then return to the authorization service.
The service page mentions insurance only as a condition for issuing the authorization. Review your policy and its terms with your insurer before allowing another person to drive.
Vehicle driving authorization on Absher starts from the owner’s account and requires a valid registration, active insurance and Absher accounts for both parties, with its period limited by the validity of the licenses and visa. Choose the right authorization type, review your insurance policy and do not use authorization as a substitute for ownership transfer.

Radiator water is the engine coolant that circulates between the engine and the radiator to carry heat away and protect the system from corrosion and boiling. To check the engine coolant level safely, park on level ground, wait until the engine is completely cold, then look at the fluid in the reservoir (expansion tank) from the outside; the normal level is usually between the MIN and MAX marks. If it is low, top up with coolant that matches the owner’s manual up to MAX, and never open the radiator or reservoir cap while the engine is hot. Repeated loss, however, may point to a leak that needs checking by a qualified technician.
What many drivers in Saudi Arabia call radiator water is actually coolant, also known as antifreeze, which is mixed with water in a ratio set by the manufacturer. It contains additives that protect the system’s metal parts from corrosion, raises the boiling point of the fluid inside the pressurised system and lowers its freezing point. To understand the role of the radiator itself and its parts, see the guide to radiator function, types and care.
Plain water alone does not provide this protection, and adding it dilutes the existing coolant, weakening its protection against corrosion and boiling; depending on its mineral content it may also leave deposits. It should only be used as a temporary emergency measure to reach a safe place if the owner’s manual allows it, after which the system should be refilled with the correct coolant at the specified concentration as soon as possible. For colours and types, see the risks of using the wrong radiator fluid, bearing in mind that colour alone does not define the specification.
In most modern cars you do not need to open the radiator to read the level; there is a semi-transparent plastic tank in the engine bay called the reservoir or expansion tank, marked MIN for the lower limit and MAX for the upper limit, sometimes shown in another form such as LOW and FULL. The level rises as the engine heats up and falls as it cools, which is why the reading is taken with a cold engine.
Locate the reservoir in the owner’s manual, and do not confuse it with the washer fluid tank or the brake fluid reservoir. In some designs the reservoir cap is the pressure cap for the system, so treat it with the same caution as the radiator cap.
Important warning: never open the radiator cap or a pressurised reservoir cap while the engine is hot or warm, because the coolant is under pressure and steam and hot fluid can spray out and cause burns. In the Saudi summer the engine bay may stay hot for longer after switching off, so allow enough time before touching any part. Make the check a regular habit and do it before trips, following the owner’s manual recommendations.
If the reservoir has run dry or the level has dropped a lot, air may have entered the system, and removing it is a job for a qualified technician.
These signs are only indications, and more than one problem can share the same sign. A leak may come from a hose, the radiator, the cap or the water pump; for pump symptoms specifically, read about the functions of the water pump and signs of failure. If the temperature does rise, read the main causes of engine overheating and what to do, and do not keep driving with a red temperature warning.
| Situation | What it may indicate | What to do |
| Level below MIN with a cold engine | A leak or gradual loss of coolant | Top up with matching coolant to MAX and watch the level |
| Needing to top up again and again | An external or internal leak, or a cap that does not hold pressure | Have the system checked by a technician rather than just refilling |
| Coloured puddles and a sweet smell under the car | A leak from a hose, the radiator or the pump | Have a technician find the source before long journeys |
| White steam with a rising temperature gauge | Overheating or a leak of hot coolant | Stop safely, switch the engine off and do not open any cap |
| Discoloured coolant, deposits or oil in it | Aged or contaminated coolant | Ask for an inspection and check the change interval in the maintenance schedule |
| Level above MAX with a cold engine | Previous overfilling | Add nothing and ask the technician to correct the level |
Coolant works in a closed system, so it should not drop noticeably and repeatedly. If you need to top up again and again, this may point to a small external leak that evaporates before leaving a puddle, a cap that does not hold pressure, or an internal leak in the engine, which may come with signs such as thick white smoke from the exhaust or a change in the appearance of the engine oil.
Do not rely on repeated refilling; ask the technician to check the system with suitable tools such as a pressure test, and tell them how often you added coolant and when. In the opposite case, where the temperature rises while the level stays stable, the problem may lie in circulation or cooling itself; see the guide to overheating without coolant loss and safe action.
The protective additives in coolant are gradually used up, which is why the manufacturer sets the change interval in the maintenance schedule of the owner’s manual, and it may differ by coolant type and operating conditions. Follow the schedule, and ask for an inspection earlier if the coolant changes colour or shows deposits or traces of oil.
A complete change involves draining the system, possibly flushing it, then refilling with the matching coolant and removing trapped air, which is work best left to a workshop. In Saudi heat, with traffic and long air conditioning use, the cooling system works under a higher load, so check the level and hoses before summer and trips. Do not pour old coolant into drains or onto the ground.
Only in an emergency and if the owner’s manual allows it, because water dilutes the coolant and weakens its protection; refill with the correct coolant as soon as possible.
It is usually between the MIN and MAX marks on the reservoir when checked with a cold engine. A reading with a hot engine is higher because the coolant expands, so do not rely on it.
This can happen when the coolant boils or its pressure rises, pushing it out through the cap, the overflow outlet or a leak point. Stop safely, switch the engine off and keep away from the steam, do not open any cap until it has cooled, then have the cause checked.
This is not recommended unless the owner’s manual or the product label allows it. If you do not know which type is in your car, ask the technician before topping up; the solution may be a complete coolant change.
The best type is the one that matches the specification in your owner’s manual, not the most popular one or one of a particular colour. Look for the specification on the container label, and choose premixed coolant if you are unsure about dilution.
Check radiator water with a cold engine from outside the reservoir, keep the level between MIN and MAX with the coolant specified in the owner’s manual, and never open any cap while the engine is hot. Plain water is only an emergency measure; repeated loss or signs of a leak call for a technician’s inspection, and a complete change is due according to the maintenance schedule.

To check car recalls in Saudi Arabia, enter the VIN on the official recall platform, then read the campaign details and follow the instructions for your vehicle. A matching model name or model year alone does not establish inclusion, and no result does not mean the car is defect-free. If a campaign applies, contact the responsible party named in it, ask about driving instructions and an appointment, and retain confirmation of the completed repair.
A recall is an action to address an announced defect, not a general description of every problem a car develops. The Ministry of Commerce explains that its enquiry service checks whether products or vehicles are included in campaigns announced in cooperation with manufacturers and local agents. Start with the official source rather than a shared image or a message of unknown origin.
Refer to the Ministry of Commerce defective products enquiry service (in Arabic) for the service sequence: access the platform, enter the VIN or search for the product, then follow the campaign details and required actions. Do not assume a recall means replacing the car; the relevant action is the one specified for the campaign once its applicability to your vehicle is confirmed.
Have the vehicle identification number, or VIN, ready. Read it from a reliable document for the car or from the location identified in the owner’s manual. Do not substitute the registration plate number or another identifier simply because its name sounds similar. For help identifying it, see the guide to your vehicle identification number, then match the details to the actual car.
Do not send full images of your documents to untrusted accounts to make an enquiry. Start through the official channel and provide what the responsible party requests through its authorised contact method, without posting your details in public comments.
Searching by product or brand name helps you find announcements, but it does not replace matching the individual car. Keep the date of your enquiry and a copy of the details for reference. Do not treat an old screenshot as a permanent answer about recalls, particularly when a new notice arrives.
Distinguish finding an announcement from confirming that your vehicle is included, and distinguish inclusion from actual completion of the required action. This table helps you choose the next step; it does not represent fixed status labels used by the platform:
| What did you find? | What should you do? |
| An announcement naming your car model | Match the VIN and check the campaign scope before assuming it applies to your car. |
| A result indicating that the vehicle is included | Read the campaign instructions and contact the party responsible for carrying out the action. |
| No result, or a search that could not be completed | Check the entry; if you have a notice or a specific concern, seek confirmation from the relevant party. |
| The seller says the repair was completed | Request the completion document and match it to the VIN and the relevant campaign. |
The absence of a recall result does not guarantee safety or replace an inspection when there are unusual symptoms. Likewise, do not attribute a noise or vibration to a campaign simply because its description seems similar. Diagnosing a fault requires a professional, while the enquiry answers a different question: whether the car is included in the campaign.
Read the full defect description, risk and instructions before planning a trip to a service centre. There is no single driving recommendation for every campaign. If the announcement specifies instructions about use or stopping, follow them. If anything remains unclear, ask the responsible party how to handle and transport the car before moving it.
Do not deliberately try to reproduce the defect, dismantle a suspected component or cancel a warning to continue driving. If the action requires a part or technical work, do not assume that buying a replacement yourself closes the campaign. To understand parts choices outside this process, read the guide to genuine, aftermarket and used car parts; follow up recall work with the party responsible for it.
When collecting the car, request a document showing the work performed and its date, linked to the VIN and campaign. Check that the details concern your car, and ask whether the action is complete or another step remains. An appointment confirmation or service-centre visit alone does not necessarily show that the recall work is finished.
Keep the document with the vehicle records, a copy of the announcement and important correspondence. If a later search seems inconsistent with the completion document, show both to the responsible party and request clarification instead of assuming one overrides the other. If symptoms remain or a concern appears after the work, report it and request a technical assessment. Proof of campaign repair is not a certificate that the car has no other faults.
Add a check for open recalls, meaning those whose required action is not yet complete, to your pre-purchase checklist. Request the VIN, match it to the car and search for yourself rather than relying on a verbal assurance or an image for a similar vehicle. If the seller mentions a completed earlier campaign, request its document and review the VIN and work details.
If a campaign applies and completion is unclear, ask the responsible party what remains before deciding to buy or use the vehicle. Do not make a recall result a substitute for a technical inspection or a review of the car’s condition; combine it with these used car inspection tips before purchase. The aim is to establish what has been verified and what needs follow-up, not to obtain a comprehensive guarantee from one search result.
Start with the correct VIN, read the full announcement and follow up with the responsible party until completion and documentation are clear. Make the enquiry part of caring for a car and checking it before purchase, not a replacement for a technical inspection or its specific safety instructions.

Choosing a car battery starts with confirming that the battery really is the cause of the problem, then matching what the owner’s manual or the current battery label specifies: size and mounting, terminal orientation, capacity in Ah, cold cranking amps (CCA) and battery technology. After that, check the manufacture date and warranty terms, and make sure installation is done properly, which may include registering the battery in the car’s system. This guide explains each step in general terms; your owner’s manual and a qualified technician remain the reference for your car’s specifications.
Do not buy a battery just because the car failed to start once. Weak starting can be linked to the battery, but also to the starter motor, the connections or the charging system. Ask a specialist to test the battery and charging system with suitable equipment, and review the car battery failure symptoms and how to test them to recognise signs worth checking.
If the engine cranks normally but does not start, the battery may not be the cause; see the guide on an engine that cranks but will not start. If the battery keeps going flat, there may be a hidden electrical drain in the car, and fitting a new battery without fixing the cause may simply pass the problem on to it. Once testing confirms the battery, prepare the following before visiting the seller:
The first reference is the owner’s manual, then the label of the original battery if it is still fitted. The table below summarises what to compare before paying and where to find it.
| Item | Where to find it | Why it matters |
| Size or group | Owner’s manual or current battery label | Defines overall dimensions and fit on the tray |
| Mounting dimensions | Battery tray and hold-down clamp | A poorly secured battery vibrates and can be damaged |
| Terminal orientation | Position of the positive and negative terminals on the current battery | A different layout may stop cables reaching or strain them |
| Capacity (Ah) | Label or owner’s manual | Indicates the energy stored in the battery |
| Cold cranking amps (CCA) | Label | Indicates the battery’s ability to deliver starting current |
| Technology type | Label and owner’s manual | Must suit the charging system and any stop-start system |
Two batteries can look alike yet differ in terminal orientation, height or mounting lip. Ask the seller to compare the new battery directly with the old one. If the current label differs from the manual, the previous battery may not have matched in the first place; rely on the manual or ask the dealer or a qualified technician.
Capacity in Ah describes how much energy the battery stores, which matters when the battery powers the car’s systems with the engine off. Cold cranking amps (CCA) describe the battery’s ability to deliver a high current at the moment of starting in cold conditions, according to a specific test standard.
A label may state CCA according to a different standard from another battery, so only compare two figures measured to the same standard, and ask the seller to clarify. The general rule is not to go below the car’s specified capacity or current.
On the other hand, a higher figure is not automatically better; what matters is that the battery keeps the correct size and technology. In cars that record battery data in their system, the actual capacity of the new battery may need to be entered during registration, so tell the technician about any difference from the original.
The general idea of each type is as follows, while the manual decides what your car needs:
In a car with automatic stop-start, the battery handles frequent engine restarts and powers systems while the engine is stopped. Fitting a lower technology than specified, such as a conventional flooded battery instead of EFB or EFB instead of AGM, may weaken system performance, shorten battery life and trigger warning messages. Moving to a higher technology should only happen if the owner’s manual or the dealer allows it.
If the battery sits inside the cabin or boot, the manufacturer may specify a sealed type or a particular vent outlet; do not fit a different battery in that location without confirming that it matches.
The manufacture date usually appears as a code printed on the lid or case or on a small sticker, and the code format differs between manufacturers, so ask the seller to explain the code on the battery itself, and prefer the most recently made battery among the matching options.
A battery stored for a long time may lose some charge, so ask whether the seller tested it before sale. For the warranty, read the written terms on the invoice or warranty card rather than relying on a verbal promise, and pay attention to the following:
High temperatures speed up the reactions inside a battery and may increase fluid loss and ageing of the internal plates. This does not mean choosing a battery simply because it is marketed for heat; it means sticking to the correct specification and technology and choosing a recently made battery.
After installation, help the battery by parking in the shade where possible, keeping the terminals clean and checking the battery and charging system during routine maintenance. For more on how heat affects the car in general, read the summer car care guide for Saudi heat.
If you are not confident about the steps, leave the installation to a qualified technician. If you fit it yourself, wear eye protection and gloves, switch the engine off and keep the key away, disconnect and reconnect the terminals in the order given in the owner’s manual, avoid letting a metal tool touch both terminals, and keep any sparks or flames away from the battery.
After installation, start the car and watch for any warning message. If one appears, return to the technician to check the installation and registration rather than trying to clear the warning yourself.
A battery contains acid and lead, so do not open it, drain it or put it in household waste. Keep it upright, protect its terminals from contact, and hand it to the seller, a workshop or a party that accepts used batteries for recycling. If it is cracked or leaking, do not touch it with bare hands and ask the workshop to handle it.
Slow cranking with dim lights may point to the battery, while a click with bright lights may point to the starter motor. These are indications, not a diagnosis, so have the battery and charging system tested and review the signs of a failing starter motor before buying.
It may be possible in some cases if the size and technology still match, but the decision rests with the owner’s manual and the technician, especially in cars that record battery data in their system.
This is not recommended; use the technology specified in the manual, such as EFB or AGM, because a lower technology may not withstand the frequent restart pattern.
No, but some cars require it using a diagnostic tool. Ask the technician or check the manual before installation, and do not assume the swap is complete once the terminals are connected.
Do not open it or throw it away with household waste. Keep it upright and hand it to the seller, a workshop or a party that accepts used batteries for recycling.
First confirm that the battery is the problem, then match size, terminals, capacity, CCA and technology to the owner’s manual, and check the manufacture date and warranty terms. Leave installation and registration to a technician if you are unsure, and dispose of the old battery safely.
