waterpump drive plug size?
 

im installing a electric waterpump on my lt1 housing and the pump i bought doesnt have the plug for the w/p or the timing cover. where do i gett these from? what size are they?

I'm in the process also, and mine also didn't come with the plug. It is a 1&1/8" 'deep' plug, I got it from Napa for something like 39cents along with a set of gaskets for around $2. Have you pressed/pounded out the old bearing yet? How difficult was it?
I screwed up, tried to press the bearing out the wrong way... and ended up cracking the housing. Now I'm eagerly waiting for a replacement, and will definitely do it the right way this time :D

Oh, the size I mentioned is for the WP housing... never read/heard anything about having to plug the timing cover. Does anyone else know if it's necessary?

it wasnt hard to get the other one out, just a lil tap tap tap with a hammer, thanks for the size of the plug.

Cool, so you just pushed the shaft right through the impeller and drive the bearing out at the same time?

a buddy of mine took mine apart and i wasnt home to see how it was done but he said it was easy to do, he used my bearing press though. but i know a hammer will do the trick though,

Just remove the front cover off the pump and pound on the center of the impellor, on the end of the shaft. I used a socket extension as a punch. It all came out pretty easy.
