OK, my pump grenaded a few days ago. Grabbed a replacement off of e-bay. Now, I don't want to install a pump if they have a tendency to blow after 100K miles.



So, is there a known flaw or weakness or age limit in these pumps? Are they as stable as the rest of the engine, and mine just took a dump? I will rebuild the replacement if needed, but I don't want to waste the money if they are pretty strong components.

they usually dont explode, just leak after a long while

Exploding = bad

Well, I said "grenaded", not "exploded" https://www.nopistons.com/forums/pub...#>/biggrin.png

It leaked violently, blew fluid all over, seemed to be behind the pulley. It's also quite crunchy when I spin the pulley by hand...



But, my question still remains, are these strong stable pumps, or should you rebuild any pump that is bought used?

a "grenade" "explodes".



ever seen a grenaded engine? it has exploded.



kevin.

my car has 189K on it, and the pump is still going. one of the hoses leaked previously, and i was adding fluid every week, but that has been replaced and its good now, no squeaks (knock on wood).

is that the coolant line?
