IMHO, the water pump should be done now. I have an '01 S with 26,000 miles on it and just did the water pump. Because it has composite impeller it can break loose apart and ruin the engine. Even though the pump baring may be good, the impeller is 14 years old. I believe the rule of thumb now is every four years it should be changed out. I was a tad late!

How was your IMSB? Was it a dual or single row?
