In a few weeks I will be replacing the timing belt and drive belts on my 1997 Toyota Camry (75,000 miles). I heard from a friend that it is typically best (i.e., most financially advisable) to also replace the water pump at the same time. In short, he argued that replacing the water pump later on (as it's own job) would cost me much more money than if I was to replace it at the same time as my belts. Does anyone know if this is true? If I had the money I would replace them simultaneously. However, things are a little tight right now, and it would be easier to do them seperately. But if it ends up costing me much more, I'll bite the bullet and do them at the same time. Thanks!
