I'm replacing the head gasket on my 1995 S10 2.2 and thought it might be a good idea to replace the water pump since I have the radiator, head, accesssory bracket, etc all off. I started looking for one and have found a lot of reviews that say after market water pumps are lousy and can fall apart after a few months, so I'm now wondering if I should just leave the original that's already on the truck alone and only replace it if it fails. The truck has 115,000 miles on it - i bought it used but as far as I know it's the original pump. GM online parts store don't show a OEM for the 2.2. Anyone know of a good water pump mfg. for the 2.2 ? I might add I have another vehicle to drive and just use this truck to haul stuff around, so it's not one I want to spend hundreds of dollars on for a water pump. I see a number of pumps priced from $20 - $50, but all seem to be made in China.
