How to Check Your Coolant Level
Checking coolant takes a minute and helps prevent overheating. A Cranbourne West specialist shows you how, safely.
Do it safely and correctly
Only check when the engine is cold — never open a hot, pressurised system (it can spray scalding coolant). Look at the expansion/overflow tank and check the level sits between the min/max marks. The coolant should be its proper colour and clean, not rusty or oily-looking.
Top up only with the correct coolant type for your car, pre-mixed to the right strength.
What it tells you
If the level is low, top up — but if it keeps dropping, there’s a leak (or worse, an internal issue) that needs finding, not just topping up. Rusty or oily coolant points to a problem worth checking.
We pressure-test for leaks if the level keeps dropping and check coolant condition at every service.
