no but if your car uses the w/p to adjust the timing belt change it when you have a new belt fittedIs it best to change the water pump every cooling flush?No. You only replace the pump if its broken.
If it ain't broke, don't fix it.Is it best to change the water pump every cooling flush?Change it only if necessary,otherwise you're spending money for nothing some people change it if they are changing the timing belt which suould be changed at 100,000 kilometers In this case it doesn't take any extra work because the pump is exposed at the same time as you change the belt..
