Car Overheating: Causes & What To Do
An overheating engine needs fast, careful action. A Cranbourne West specialist explains the causes.
What it usually means
Overheating is usually a cooling-system problem: low coolant or a leak, a failing water pump, a stuck thermostat, a faulty radiator or fan, or in worse cases a head-gasket issue. In Melbourne traffic on a hot day, a weak cooling system shows up quickly.
Continuing to drive a hot engine is one of the fastest ways to cause expensive damage.
What you should do
If the temp gauge climbs into the red, safely pull over, turn the engine off and let it cool — don’t open a hot radiator cap. Then get it checked or towed.
We pressure-test the system and check the pump, thermostat, fans and radiator to find the cause.
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.
