AC Delco water pumps

[Jimmy87T]

Ready for a new water pump. My car is 99% stock with 118K. I've found 2 numbers for AC Delco water pumps on Rockauto: 251-639 (OEM design, $120) and 252-582 (<$30). What (other than the price) is the difference between the 2 and has anybody used the new $30 Delco water pump?

Been using the AcD 252-582 for years. No issues to date.

Thanks, guys. I like to use AC Delco when I can...and the price is right.

I found out AC Delco makes cast iron like OEM and aluminum.
251-639 is cast iron
252-582 is aluminum

I just finished installing the water pump today and I went with the cheaper one since I want to find someone to rebuild my original (with the stamped date). Check out Highway Stars web site.

my next two project is to install a tranny cooler, and replace the tranny.

ACDelco is not always made in U.S.A. & often relabeling Chinese (JUNK) parts.

I bought the aluminum one. When I got it home I noticed right on the box: Made in USA with components from China, Slovakia, and USA. Chuck Yeager told me to keep my GM car all GM with AC Delco parts...WTF happened?
