I'm in the process of replacing my water pump seals and bearing, and the slot nut will not budge. I've tried the nut tool and the punch and hammer method and the damn thing will not move. What do you guys think I should do next? Oh and I know its a left handed thread so thats not my problem.

I'm just about to take it to the dealer.

 

Anyone???? I'm about to go crazy. I have never seen anything on so tight in my life

 

Use the right tool and a good impact or get a bigger hammer and smack the S#$T out of it.
