I did my pump myself for under $100! I will never pay for what i can do!
Generally, no. Mine had 150k and I could see no reason to replace the housing. In fact, O'Reilly didn't even offer and option to buy the cover, they would only sell me the pump itself.Does the Water pump cover need to be replaced when replacing the pump itself? My Truck has 176k miles on it but I don't want to replace something that doesn't wear out.
WTF.........could GM made it any harder too replace a water pump, never heard of removing a harmonic balancer to get to water pump.....i guess they figure the average D.I.Y. guy is not going to do a water pump themselves, I can remember how easy it is to replace a water pump on a S/B or B/B chevy i guess thats the difference between a gasser and a diesel
Looks fine to me. I'd run it like that.I really appreciate the good write-up and pictures from Flagstaff and TheBac. They have been very helpful so far in replacing mine :thankyou2
I'm halfway there. Today I took my time to disassemble everything and tomorrow I'll be putting it all back together with the new pump.
Got a few question though. Do I need to replace my pump housing due to pitting? I see others with slight pitting on the cover but I was wondering at what point is it too severe and need to be replaced?
Pics of the pump cover. 155k on mine
This flexplate holding tool saves a lot of time and hassle when removing the balencer bolt. Well worth $15, not having to mess with removing the starter.no one mentioned is the balancer bolt or the fan a reverse thread? starting this project tomorrow
