Should I Replace the Water Pump At The Same Time As The Timing Belt?


Getting a water pump and timing belt replaced can be a daunting experience, comparing all the different quotes and choosing the right one can be tricky. Often customers come to us asking whether the water pump really needs to be replaced at the same time as the timing belt (also known as the cambelt). What we normally say is that whilst your water pump may not be faulty it may still make sense to get it replaced.

Save on labour cost

The main reason is that on most cars, to get to the water pump, you usually have to remove the timing belt first. If that is the case on your car as well, then it is advisable to replace the water pump at the same time as the timing belt while the mechanic has access to both parts. Once the belt is removed, it is only a matter of loosening a few more bolts and screws to change the water pump as well. That way you will kill two birds with one stone because the majority of the labour needed to replace the water pump will already have been done when replacing the timing belt. Considering that water pumps generally do not cost a lot, it makes sense to do both at the same time.

If you don’t replace the water pump…

Not replacing water pump during a timing belt change means if the pump does go at a later point, you will have to pay for the same labour again. It is likely the water pump will probably have worn after some years of use anyway, and will need replacing sooner than later.

Making sure the water pump is in tip-top condition is key to avoid overheating of the engine, and avoid potentially expensive repairs. Even the slightest leak in or around the water pump can reduce the ability of the engine to keep itself cool.

That’s why we at ClickMechanic do always recommend to get both the timing belt and water pump replaced at the same time. We even have a dedicated job available in our repairs section on the site that will give you a full quote for a timing belt and water pump.
