I was concerned about replacing my waterpump a couple of weeks ago, so I checked out Pep-Boys for the cost of a new one. They had a beautiful Bosch unit for $62.99. Unit had a thick black impeller and looked beefy. I have a 97 GL Sport V6 ATX with 145K miles and I'm still running the original pump. Temp gauge just about always reads just left of the 'N' in Normal. I'm going to keep the original in until necessary. Car is like the Energizer bunny, it just keeps going and going and going.....
