Can I carry out a car water pump replacement myself?

Replacing a car water pump isn’t as straightforward as you might think. We’d suggest only a competent and experienced home mechanic undertake this repair/replacement. If you don’t get things quite right, the consequences can be severe, leading to engine failure.

Replacing the pump itself isn’t the hard part—it’s removing and reconnecting the timing belts or chains, and that’s a job better left to a qualified mechanic.

What additional factors could affect water pump replacement?

Time is the biggest factor. As we’ve said, they can be tricky to get to, so the labour costs can creep up with those problem replacements.

Another major consideration when you replace your water pump is your timing belt.

The water pump relies on the timing belt to ensure its optimum performance. A worn or loose timing belt can impact the water pump’s operation significantly, which, in some circumstances, can result in engine seizing. As you can imagine, replacing an engine is likely the most expensive and troublesome repair a driver can ever expect to suffer. That’s why when it’s time to change a water pump or the timing belt, they’re almost always carried out together.

You’ll also need to replace the coolant in your system and seal all the joints with the correct sealant.
