After process of elimination the inner main seal was bad. This is behind the impellar in the water pump. It's a pain in the @#! to get out without nicking up the housing. My problem is how do I press it back in without damaging it. I already broke one new one($50.00). Any sugestions?

 

I put one in last year. Think I put it in with a press of some sort. Good Luck, sorry I can't be anymore help
