What is the lifetime of water pumps?
I got the water pump replaced 8000 miles age (around 2 years ago) when changing the timing belt. Today I showed my car to a mechanic for a noise that is coming from under the hood. This noise has been around for two weeks now. After checking the car, he mentioned that the water pump needs to be replaced. I told him that the water pump is fairly new and he blamed low-quality pumps.
So is it possible for a waterpump to go bad after only 8K miles?
BTW, during these two weeks the car has not overheated and I have not seen any leak. But the mechanic says he saw little coolant leaking.
Update: the water pump bearing was faulty (after 8K miles). I was told it was a low quality pump.
