ACDelco Gold 252-581 (88926095) Engine Water Pump

Good price

Good fit on 1964 nova

I have a 68 327 with with ac, power steering, air pump and an alternator. 68 was the last year of the SBC short pump and specifications are critical and this met my requirements where the first pump (Gates not bought on Amazon) didn’t and caused interference of my belts and pump pulley which is obviously a bad thing. The height from the mounting surface to the top of the pump pulley mount must be 5 5/8 or your belts will not align properly. This is something that hit or miss with many lower priced after market pumps. However the back plate on this pump hits my timing cover slightly that could easily be remedied with a thicker gasket. In my case it was just barely touching and posed no issues IMO. Well built and installed easily. Recommended!

I bought for my 69 GMC pickup 350 v8

AC. enough said Awesome

I had all sorts of reservations about buying and mainly seeing other more mainstream options were in the hundreds of dollars but figured would give it a shot. One thing I didn't know is if rotation would be an issue but ends up both my motors turn in the same direction and that's the same direction as autos. The inside impeller is much different than my original which was brass but the impeller on this looks to be stainless or perhaps galvanized, along with the backplate, and the coolant is the same between auto and boat so not like it's something subjected to salt water. I did have to coat it and used motorcoater which I already had so super easy. Another difference between OEM and this is the extra hole/port on the one side, OEM does not have this but there's an opening on the block for it which would have to be blocked off or the OEM one wouldn't work so no problems with that difference. Just as an FYI, my motors are 2008 models with outdrives (may be relevant as perhaps the outdrives is where the rotation occurs) and of course I can only speak to my exact setup.

Installed on 1972 GMC with 350 engine. Installation went smoothly and the pump performed great! Highly recommended!

Less than a month of use pump leaked . After scheduling pump replacement the seller claims part is not returnable after 1 month. That’s not right downtime and labor costs is bad enough then get screwed on cost of faulty part. Most parts have a 1 year warranty. What happened?

It’s good and works good. I’ve never had a problem with the AC Delco.

Came exactly as described installed in minutes and works perfectly!

Fits like new on my 1979 mercruiser 228 (chevy 305) it is the short style waterpump
