How to Check Coolant

WHAT DOES ENGINE COOLANT DO?

Coolant mixes with water in an engine’s cooling system. It is designed to both lower the freezing point and raise the boiling point of the fluid in the system.

This means, by adding coolant/antifreeze to your car’s cooling system you’re able to increase the temperature a vehicle can run at before the cooling system will boil.

HOW AND WHEN SHOULD I CHECK MY COOLANT?

The maintenance of your vehicle’s cooling system is important. Its recommended that you check your coolant every few weeks to ensure it remains at the correct level and you should generally have your coolant changed every 2 years or 40,000km as some of the additives can deteriorate and reduce the effectiveness, which will decrease the efficiency of your vehicle.

Always check the vehicle manufacture’s recommendations for correct coolant replacement intervals.

To check your vehicle coolant level, firstly you will need to open the vehicles bonnet.

Important safety Message

Never open a vehicle’s radiator cap when the engine is hot. This can result in serious burns and injury.

With the engine cold, locate and remove the engine’s radiator cap.

Visually check that there is coolant in the radiator.

If the coolant is low, top the system up with clean cold water.

It is ok to just top the cooling system up with water instead of coolant as your coolant glycol levels are check at your routine maintenance service.

Mixing different types of coolant can cause damage to the cooling system.

Some vehicle are fitted with a coolant overflow or expansion bottle.

Check the level of this bottle and top up as required.

Ensure to re-fit radiator cap once this check has been completed and then close the bonnet.
