I have a 01 Formula and my factory pump has been leaking for a while now. I dont have the money for a electric pump, I havnt realy found any solid advice on which pump is good. I hear that the LS1 water pumps are no longer made and we have to use LS2 pumps which have t-stat and t-stat housing as two peices. This pump says its a LS1 pump any help would be appreciated. http://www.autozone.com/autozone/par...536568_4487_0_

 

Looks like the one I got from Autozone to put on my LS6 last year and my LS1that came in the car originally, works fine for me. We are some what limited with either high dollar (Edelbrock, Meziere, Evans) low warr, or low dollar (autozone, orileys, Carquest) liftime warr, I change my WP every 2 years so the warr is whats important to me. I would say save your money and get the good warr. I do only use the rubberized alumunum gaskets, the pumps somtimes come with paper ones they seem to leak.

good luck

 

say if I was to just get the LS2 water pump, what would be the difference, the two peice t stat and housing.. I realy dont want to be changing out my water pump to often, its going on my DD

 

aftermarket still makes the LS1 pump........and ALWAYS use GM gaskets

 

dude if you want to make the trip up to NoVa, i will sell you my pump for $50, its a GM pump, only had it on for around 1k miles before i went with an EWP.
