What is Coolant?

So, what is coolant? Coolant, also known as antifreeze, is an essential fluid that helps keep your engine at the right temperature. It is made up of water and special chemical additives. Coolant prevents your engine from overheating in hot weather and freezing in cold weather. This important fluid flows through the engine and radiator, carrying heat away from crucial parts to keep everything running smoothly.

Why is Coolant Important?

Temperature Regulation: It prevents engine overheating and freezing
Corrosion Resistance: Additives protect engine components from corrosion
Freezing Protection: Remains effective even in temperatures below 0 degrees Celsius
Boiling Prevention: Maintains performance when temperatures exceed 100 degrees Celsius

Simple Steps on How to Check Coolant Levels

Checking your coolant levels is a simple task that can be performed without removing the radiator cap. Follow these steps to ensure your coolant is at the appropriate level:

Locate the Coolant Reservoir: This is usually a translucent plastic tank found near the radiator.
Check Level Markings: Look at the side of the coolant reservoir for clear indicators of “full” and “low” levels.
Assess the Coolant Level: If the coolant is below the “full” line, additional coolant is required.
Ensure the Engine is Cool: Always check coolant levels when the engine is cool to avoid injury from hot fluids.
Add Coolant: If necessary, carefully remove the radiator cap and add pre-mixed coolant or a 50/50 mix of coolant and water. Be sure to check the container for pre-mixed options.
Inspect for Leaks: Examine the radiator hoses and surrounding areas for any signs of leaks or damage.

By following these simple steps, you help maintain your engine’s health and prevent potential overheating.

Warning Signs: When to See a Service Technician

Paying attention to your coolant system can help prevent serious engine damage. Here are some warning signs that it’s time to see a service technician:

Thick or Sludgy Coolant: If the coolant appears thick or sludgy, it may indicate a problem with the internal gasket.
Persistent Leaks: Continuous leaks can lead to rapid coolant loss, increasing the risk of overheating.
Frequent Engine Overheating: Regular overheating can be a sign of low coolant levels or an underlying cooling system issue.
Coolant Warning Light: If the coolant warning light on your dashboard illuminates, address the issue immediately.

Promptly addressing these signs can help you avoid severe problems and keep your vehicle operating at its best.

When to Change Coolant

Regular maintenance is essential for keeping your cooling system working well. You should check your coolant levels every three to six months. If the coolant looks discoloured or dirty, it’s time to flush the system and replace the fluid. This process removes any contaminants and ensures that the coolant can protect your engine from extreme temperatures effectively.
