What Is Engine Coolant (and Why It Matters)?
Coolant does far more than stop your engine freezing. A Cranbourne West specialist explains.
What it is & what it does
Engine coolant (antifreeze mixed with water) carries heat away from the engine, raises the boiling point, lowers the freezing point, and — crucially — contains corrosion inhibitors that protect the radiator, water pump and engine internals.
Different cars need different coolant types, and they shouldn’t be mixed.
Signs of trouble & how we help
Those corrosion inhibitors deplete over time, so old coolant leads to corrosion, blockages and overheating — which is why it needs changing on schedule. Using the wrong type can cause gelling and damage.
We use the correct coolant for your car, check its condition at every service, and change it on schedule.
