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 say is that if your water pump is driven via the timing belt (cambelt) it must be replaced at the same time, a water pump failure can be as catastrophic as a timing belt failing on these vehicles.
Save on labour cost
The main reason is that on some cars, to get to the water pump, you may have to remove the timing belt first even if it is driven via the auxiliary drive belt. If that is the case, then it is advisable to replace the water pump & auxiliary drive belt at the same time as the timing belt while the mechanic has access to all the parts. Once the timing 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. Not replacing the water pump on these vehicles 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.
If you don’t replace the water pump…

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.
