Water Pump Replacement Cost Calculator
Estimate the cost of a water pump replacement. On belt-driven engines the water pump is often replaced with the timing belt. The vehicle type and whether you use genuine or aftermarket parts are the main cost drivers, along with the labour to access the part.
Your water pump replacement details
Your estimate sits within the typical range.
If the pump is timing-belt driven, do the belt at the same time (and vice versa), they share nearly all the labour. A failed water pump causes overheating that can crack the head, so replace it at the first sign.
💰 Ways to save
- Aftermarket parts are cheaper than genuine and fine for most jobs, ask your mechanic which matters here.
- Do related wear parts at the same time while the area is already apart, it saves a second labour charge.
- Get a couple of quotes, labour rates and parts mark-ups vary a lot between workshops.

The pump itself is modest, the labour to reach it is the variable. On timing-belt-driven engines it shares nearly all the labour with the belt, so the two are best done together.
