<< IMHO, this is really a non-issue. If a water pump shaft seal lasts long enough for cavitation to cause erosion on the pump impeller, you have gotten you money's worth from that particular pump. >> AH! yes indeed..except most people don't replace the pump they just replace the face plate and impeller. the housing (the WHOLE pump) is the part that wears. It's the BACK of the pump, the aluminum part on the block, NOT the iron/steel impeller! In it's life the van may have had 5-6 pump "faces" on 2 or 3 different engine blocks..all with the same housing!...So, my point, if I may reiterate, if you have reason to have the engine our or apart enough that the pump housing is accessible ..it's time to replace the pump and if you are JUST doing the face plate and impeller, CHECK the housing! Your point about the nature of the cooling system in general gives all the more reason to do this.. Or do as you darn please and I'll get *another* diesel westy cheap.. ;-) BTW, anyone have an upper hose for a 83 diesel?..yes THAT hose..and no, DON'T ask.... :*)
