The Hidden Dangers of Using the Wrong Radiator Fluid
Table Of Contents:
|
Many drivers overlook the importance of radiator coolant color, assuming it's just cosmetic. But choosing the wrong type can lead to serious engine damage. So, what are the differences between coolant types—and which one is right for your car?
What Is Radiator Coolant?
Radiator coolant, also known as antifreeze, is a chemical compound used to regulate engine temperature. Its primary function is to prevent the engine from overheating in hot conditions or freezing in cold ones, protecting internal components from corrosion and damage.
Coolant is typically made from ethylene glycol or propylene glycol, with added corrosion inhibitors and thermal stabilizers.
Types of Radiator Coolant and Their Differences
Coolants used in radiator systems fall into three main categories, each with distinct properties that directly affect engine performance and efficiency:
1. Regular Water
Although easily accessible, using plain water in the cooling system is unsafe. It contains high levels of salts and impurities that accumulate inside the radiator and engine components, causing corrosion, rust, and long-term damage.
Water also boils quickly and freezes easily, making it unsuitable for temperature fluctuations.
2. Green Coolant
Green coolant is a balanced mixture of water and specially formulated chemicals designed to cool the engine efficiently without reacting with its metal components. Key features include:
- Free from salts and impurities, preventing corrosion and rust
- Boiling point raised to 120°C, making it effective in high-temperature conditions
- Commonly used in older vehicles or those with iron-based components
- Safe and effective, though its lifespan is shorter than other types
3. Red Coolant
Red coolant shares the impurity-free nature of green coolant but offers enhanced features:
- Contains agents that prevent freezing in extremely low temperatures
- Free from silicates, which can cause long-term corrosion in engine parts
- Used in modern vehicles requiring extra protection for sensitive metal components
- Longer lifespan than green coolant, ideal for cold climates
Causes of Coolant Boiling in the Radiator
Boiling coolant is a serious warning sign of a malfunctioning cooling system. Ignoring it can damage vital car components. Common causes include:
- Faulty Thermostat: Regulates coolant flow between the radiator and engine. If it fails, the engine doesn’t receive adequate cooling, leading to overheating and boiling.
- Cooling Fan Failure: The fan plays a crucial role in cooling the radiator. If it stops or underperforms, engine temperature rises, causing the coolant to boil.
- Damaged Radiator Cap: Should be replaced every two years. A worn or loose cap affects system pressure and reduces the radiator’s ability to maintain proper temperature, contributing to boiling.
Causes of Coolant Loss in the Radiator
All coolant types can decrease over time due to mechanical or operational issues affecting system efficiency. Key causes include:
- Faulty Thermostat: Disrupts temperature regulation, leading to coolant loss
- Cooling Fan Malfunction: Reduces radiator cooling, increasing coolant consumption
- Water Pump Failure: Responsible for circulating coolant to the engine; any damage causes noticeable fluid loss
- Leaks or Cracks: In radiator pipes or the reservoir tank, leading to gradual coolant reduction
- Heavy A/C Usage: Prolonged use increases pressure on the cooling system, accelerating coolant consumption
When Should You Change Your Coolant?
Coolant replacement depends on its type and chemical composition:
- Red Coolant: Recommended every 4 to 5 years due to its long-lasting organic formula
- Green Coolant: Should be replaced every 2 to 3 years, as its protective agents degrade over time
What’s the difference between green and red coolant?
Green contains silicates and has a shorter lifespan; red is silicate-free and lasts longer.
Can you mix coolant colors?
No. Chemical reactions between types can damage the cooling system.

Rear-Wheel Drive (RWD) Systems, Performance and Advantages
Do you ever Wondered What Makes Rear-Wheel Drive So Fun in Sports Cars? Discover how a rear-wheel drive system influences a car’s performance — and whether it's the right choice for you in different driving conditions.
What Is Rear-Wheel Drive (RWD) in Cars?
- Rear-wheel drive refers to a drivetrain system where engine power is delivered to the rear wheels of the vehicle.
- This power is transmitted through several main components — starting from the transmission, moving through the driveshaft, and finally to the differential, which distributes power between the rear wheels.
- RWD systems are known for their relatively simple design and more compact engine layout compared to front-wheel drive (FWD) or all-wheel drive (AWD) setups. This makes RWD particularly well-suited for performance vehicles.
Advantages of Rear-Wheel Drive (RWD)
- Better Power Delivery: With power going to the rear wheels, RWD cars often provide more balanced acceleration, especially under heavy throttle, improving traction and handling dynamics.
- Superior Steering Feel: Because the front wheels are dedicated solely to steering (not driving), the system offers enhanced feedback and control, especially in variable conditions like rain or snow.
- Towing Capabilities: RWD places the weight closer to the driven wheels when towing trailers or caravans, resulting in better stability and steering control.
- Reduced Torque Steer: RWD separates engine power from steering forces, resulting in smoother and more responsive handling.
- Near 50/50 Weight Distribution: RWD allows for better balance between the front and rear axles, improving vehicle stability and cornering performance.
- Improved Durability: Fewer components are subject to wear compared to AWD systems,
- making RWD generally more robust and mechanically simpler.
- Lower Maintenance Costs: Due to the simpler mechanical structure and reduced parts, RWD vehicles often cost less to service compared to AWD vehicles.
Drawbacks of Rear-Wheel Drive (RWD)
- Challenging in Poor Weather: RWD vehicles can be harder to control in rain, snow, or icy conditions, although modern systems often include traction control and stability control to mitigate this.
- Reduced Cabin Space: The presence of a driveshaft and rear differential can take up space inside the vehicle, limiting footroom and cargo space.
- Increased Weight and Fuel Consumption: The added weight of the driveshaft and its tunnel contributes to higher fuel usage compared to FWD cars, even though some AWD systems are heavier overall.
- Less Common in Economy Vehicles: RWD is more prevalent in performance and luxury cars; budget-friendly or compact models often favor FWD for efficiency and space.
- More Difficult in Slippery Conditions: Since the rear wheels push rather than pull the vehicle, maintaining traction on snowy or icy roads can be more difficult.
Popular Rear-Wheel Drive Cars

The engine is the car’s core, and cylinders convert fuel into motion. Knowing their role helps drivers and enthusiasts make smart choices in buying, maintaining, and understanding vehicle performance.
What Is a Cylinder?
A cylinder is a precisely engineered, cylindrical chamber typically made from cast iron or aluminum alloys to withstand high temperatures and pressures. Inside it, the piston moves in a reciprocating motion—up and down. Engines vary in the number of cylinders, usually ranging from 3 to 12, and this number directly affects the engine’s performance, smoothness, and efficiency.
Cylinder Function and the Combustion Cycle
The core energy-generating process occurs within each cylinder through a four-stroke combustion cycle:
- Intake Stroke: The intake valve opens, and the piston moves downward, creating a vacuum that draws in the air-fuel mixture.
- Compression Stroke: Both intake and exhaust valves close, and the piston moves upward, compressing the mixture to increase its energy density and flammability.
- Power Stroke: The spark plug ignites the compressed mixture, causing an explosion that forces the piston downward with great force—this motion is ultimately converted into rotational energy that drives the wheels.
- Exhaust Stroke: The exhaust valve opens, and the piston moves upward again, expelling combustion gases from the cylinder to prepare for the next cycle.
