waterpump, waiting game Options

[soven]

I bought my car at 91000kms , did a cambelt change then and other normal tuneups but the waterpump was left out.Mechanic told me at the time that it didnt need to be changed since it was fine and I went along since I didn't know much about cars.

Is it just a matter of time before the waterpump would fail or are they supposed to last. What are the implications of it failing? Overheating?

From what I gather, if I was to get someone to change just the waterpump now, it would cost quite a bit?How many hours of labour would it be.

I would have just changed out the water pump for safety reasons. For the 5S engine, I do know that if the water pump stop working, it would jam up, not spin, and actually eat up the timing belt. So, If you just changed out your timing belt with a new one, expect to get another one from Toyota. Thats what happened to my camry. The water pump just stopped spinning and the belt just slashed it self trying to go across the cam and crankshaft. At the end I just bought a Life time water pump and a new belt. Sucks not to do it again, but to buy the same things again and something extra.
