Which side is it leaking from?

Not uncommon for the o ring on block side to become dislodged during install, need to lube it so it won't bind
If the cover side is leaking... Unless it has updated cover and gasket no suprise as they tend to leak.
My money is on o ring if it's just pouring out. You'll have to remove it and check at minimum.

 

Im with rodnok, O-ring. i rub oil on it before seating it in it's groove in the housing. Do you have any pictures?

 

 

This picture was before the install where I finally got the o ring to seat. I have picture of the other o ring seated to but I didn’t post it. I will remove the cover and try again. Maybe it became unseated? I did not crank or attempt to crank the engine. It seemed to be leaking g from the bottom. With the gasket and the cover it Pilsner be coming out the side where the hoses meet up, so it’s got to be coming out the timing belt side.

 

Your engine uses timing chains - the little belt you see is the water pump drive belt and tensioner system. While you're in there, change that little 3-rib pulley too. When - not if - it fails it gets very expensive in a hurry.

Guess I’ll be buying one net paycheck.

 

Well I didn’t put any of this sealant the first time around so that is why it leaked right out when I tested it, but hey it’s first time. Anyhow I realized a sensor had come a loose and once I got that back together it cranked like normal. So I put it all back together and now waiting 21 hours to let it cure. I gotta beat work by 15:00 hours today so I can only wait 21 hours or rather it will be 21 hours by then.

 

That o ring shoukd be replaced when cover taken off and it's never a bad idea to run some gasket maker as a back up. Doubt it leaks from there now....

 

I have done two northstar water pumps without any sealer, no leaks. I do normally put a little silicon grease on the o-ring to hold it. That o-ring can be a bit of a pain to keep in place but not bad.
