Coolant Leak: Causes & What To Do
A coolant leak risks overheating if ignored. A Cranbourne West specialist explains the causes.
What it usually means
Coolant (bright green, orange or pink) can leak from a radiator, hoses, the water pump, a thermostat housing, the header/expansion tank, or in worse cases a head gasket. You might see a puddle, smell a sweet odour, or just keep needing to top up.
European cars commonly develop coolant leaks from ageing plastic housings and tanks that become brittle with heat.
What you should do
Don’t ignore it — running low on coolant leads to overheating and serious engine damage. Top up if needed and get it checked.
We pressure-test the cooling system to find the exact leak point before replacing parts.
How we find & fix it
Because the same symptom can have several causes, we use dealer-level diagnostics and a methodical check to pinpoint the real cause — rather than throwing parts at it.
