Water Pump Maintinance questions

Ok, im looking into a car, and the water pump hasent been changed since 96, which was 53k miles ago. It was pressuer tested once in april, and passed with flying colors, and more recently 2k miles ago in may and again passed with flying colors. What do you guys think i should do? What can happen if i leave it be, and it starts to fail?

Leave it. Per my understanding, this is one of those "if it ain't broke, don't fix it" deals. You'll know when it is going bad because you'll be leaking coolant.

If it passed that easily, I wouldn't be worried.

Unfortunately, on these cars, it's not leaks that you have to worry about. These water pumps have a tendency to seize the bearings. The water pump is driven by the timing belt. If it siezes, the timing belt starts dragging on the pump pulley, and the timing belt can break. Now we all know what happens whan a timing belt breaks.

Most people change their water pump every other timing belt change. (about 60K miles) I have no idea what effect age has on the pump. Anyone else care to chime in on that subject?

I guess an important question for me to ask is, How do these things break, Do the slowly go, and then after a little bit Seize, or do they just all of a sudden go.

Not that I wouldn't be concerned about the pump but I'd really be concerned about the timing belt.

T-belt was done. I have reciepts for it. replaced 12may04 2k miles ago. One of the times they tested the water pump was when they did the T-belt and said the pump didnt need to be changed.

I wouldn't be too concerned. The pump that I pulled off this spring was over 11 years old, and had a leak, twice. I did not get my core charge back though. The impellers had eaten into the pump housing, and the timing belt didn't snap. YMMV.
