ACDelco 252-719 Professional Water Pump Kit

Excellent pump and deal. Came with pump and both gaskets as expected. You do need to transfer the old pump studs to the new unit (expected, and a simple YouTube search will show you how; it requires no more than a wrench and the original stud nuts to complete). Thank you!

Fit perfect on my 1990 chevrolet 5.7

Tengo un año con ella ya y ha jalado muy bien a principios se escuchaba el balero pero no le tome mucha importancia ya que pudo ser porque era nueva y así fue se le quitó a las semanas aún recuerdo y hasta ahora todo perfecto eso si hechenle anticongelante para mayor rendimiento

I can not say anything negative about this part , It fit my G.M.C. truck , It works well , and no more adding water and antifreeze to the radiator . Great replacement part .

This is the third water pump on my 1991 Chevy Astro, not surprising considering the van is now 32 years old. As the 4.3L Vortec engine shows no signs of wear, I don't mind replacing a bunch of external wear&tear parts (idler pulleys, fan , fan clutch, which I also reviewed here on amazon.com). The AC Delco water pump fit perfectly right away and is working flawlessly. As the previous generic pump lasted 17 years, I expect this one to do just as well or better. Although I doubt that I'll get to keep this van until its 50th birthday, but who knows.
