Re: Water pump for an L31?
i just used the pump for the 90 k5 blazer with 5.7 and serp belt for my setup as i used the serp belt stuff also .
if v-belt just get one for say a 1985 350 .
dont forget L31 vortec has no bypass hole port in the block so you need to do a bypass hose like a bbc uses . or you can get bubbling / girggling / coolant smell as it pushes up in to the over flow tank .
