$50 ACDelco 252-608 Professional Water Pump with Housing
My sense is to get the cheaper professional water pump, given that it is 'professional' and seventy bucks cheaper.
Can anyone tell me if I am missing something here? Why is the better product so much cheaper?
I replaced my fan clutch about five years ago, should I bother replacing that as well? It seems to work fine. It was a AC Delco heavy duty one.
Thanks all for your help!
all the best
Could be lots of differences...
-Rebuilt vs. new
-Import vs US made
-Heavy duty bearings vs regular
You'd be best to try and find the specs on the two before choosing. There are often reasons to go with the more expensive option, but sometimes it's expensive just 'because' with no real difference.
I had a similar experience replacing an idler pulley on my 1999 Suburban...in the end the cheaper one (that looked identical) had much lighter duty bearings on it and made the decision easy.
