What Does a Water Pump Do?
The water pump keeps your engine cool — and is a common failure point. A Cranbourne West specialist explains.
What it is & what it does
The water pump circulates coolant through the engine and radiator to carry heat away. It’s usually driven by the timing belt/chain or the drive belt, and runs constantly whenever the engine does.
On many engines it’s replaced with the timing belt because the labour overlaps.
Signs of trouble & how we help
A failing pump leaks coolant, whines, or causes overheating. Because it’s often behind the timing cover, catching it during a timing-belt service saves paying the labour twice.
We pressure-test for leaks and advise whether to bundle it with the timing job.
