What is an Engine Coolant?
Engine coolant is a specially formulated liquid that circulates through your car’s cooling system, maintaining a stable temperature for the engine. It’s typically a mix of water and antifreeze, with antifreeze made from ethylene glycol or propylene glycol.
Functions of Engine Coolant;
- Temperature Regulation
- Corrosion Protection
- Lubrication
What is the Importance of Engine Coolant?
Engine coolant plays a crucial role in the engine’s components. It serves multiple functions, including;
Temperature Regulation
Maintains the engine's operating temperature by absorbing heat and preventing freezing.
Corrosion Prevention
Protects engine components, including the radiator, from rust and corrosion.
Lubrication
It keeps the water pump and other internal parts running smoothly. Neglecting coolant maintenance can lead to overheating, costly repairs, or even engine failure.
What are the Signs for Engine Coolant Replacement?
The most common signs that indicate it’s time to replace engine coolant are the following;
Engine Overheating
Persistent overheating suggests that the coolant may be old or insufficient.
Coolant Discolouration
Healthy coolant is bright green, orange, yellow, or pink. If it’s dark or rusty, it’s time for a change.
Smelly Coolant Leaks
Puddles with a sweet odour under your car may indicate a coolant leak.
Dashboard Warning Lights
Many vehicles have indicators for low coolant levels or engine overheating.
How to Replace Engine Coolant in Your Car

- As air escapes, you’ll notice bubbles. Once they stop, close the radiator cap.
Check Coolant Levels
- After the engine cools, check the coolant reservoir and top it off if necessary.
