I have a 1991 firebird with a bad water pump it is the one that came on the car new but the pully bolts are suck and I have trid every thing to get them off but I can't. I don't what to cut them so any one know how to free them up.

 

I just had a socket on one bolt with a friend holding a breaker bar on an opposite bolt. Worked well for me.

 

Did you try to crack them loose with the belt still on? You could also try an impact gun and/or heating them up with a torch.

 

Soak them in PB blaster over night. That stuff can be your best friend when getting out stubborn bolts.

 

Yeah, soak it with pb blaster. Also, I kept the belts on tight, so it held the pully. I also used a breaker bar on the opposite bolt. It was easier than I thought. Have a buddy to help.

 

This is how I did it before I bought a breaker bar...

 

I have not tried to soak them in PB blaster yet, but I have tried a impact gun and not the little one and it did even come close to breaking it lose.

 

Try a torch. Heat the suckers up and try moving them again.

If all else fails, cut them off with a dremel or similar tool. Just the bolt heads, so the pull falls right off. You can grab new bolts at the junkyard(it took me five minutes to get all four bolts off an engine there). You're replacing the water pump, so the remains in the old pump are moot.

 

Wow....hey, at least it worked.

 

im in the process of doing the same thing. when you get the pump off make sure your gaskets good and that you rtv the heck out of it. i had to redo mine 3 times cause the rtv diddnt set right. to get them off just use a socket and a open bolt wrench and have a friend hold one wile u twist the other.

 

Thats for the tips
