When to Change Your Coolant (Antifreeze)
Coolant doesn’t last forever — old coolant can cause overheating and corrosion. A Cranbourne West specialist explains.
Why coolant needs changing
Coolant does more than stop freezing — it raises the boiling point and contains corrosion inhibitors that protect the radiator, water pump and engine internals. Those inhibitors deplete over time, after which corrosion and blockages start.
Old, rusty or weak coolant is a common hidden cause of overheating and water-pump failure.
Getting it right
European cars need the correct coolant type and concentration — mixing the wrong types can cause gelling and damage. We use the right coolant for your car, at the correct strength, and follow the manufacturer interval (often every few years).
We check coolant condition at every service and flag it when a change is due.
