Snapped a bolt - help me before Lars gets here!
So my question is now...are the bolt holes on the water pump threaded? It looks like this is the original pump. If they aren't, I think I should be lucky enough to still remove it and have enough of the bolt showing to hopefully remove it.
I don't want to cause any further damage until I get some good advice!
Thanks,
Tony
edit:
I also have a bracket for A/C. I don't know if this makes things worse or better?

I tried the vice grips, this thing ain't budging. I lubed it up with some super penetrating lube stuff & will try again in the morning.
You could also try drilling a small hole along the bolt (might cut into pump a little) to try and give it breathing space which may help it to move.
I am still up working so if you have more questions IM me.
I wish you the best of luck.

2 AM I just got in ... I won't go into how much I did (Lots) and how much to do (lots),
but I might be driving mine in the driveway come Saturday.
Like these guys said ... get the pump loose and outta there.
Looks like it might need some heat on the pump to loosen.
WATCH the radiator .. you don't wanna compound this.
It looks like the shank of the bolt might be healthy.
If so - after sliding the pump off - I would try a small pipe wrench.
Forget vice grips - the pipe wrench grabs harder - the harder you push.
If that doesn't do it, then we could try welding a nut on the end to wrench it off.
I hope we have some cars to tune.
I wish! I was doing my LAST MBA assignment. Thankfully the vette doesn't need much work done to it now. I still have to install the X-pipe, a new coolant tank and a rag top.
Anyway back to the problem.
Did you get the bolt out?

It seems all of us in New England have -something- to get fixed up before Lars gets here.
I'd just remind everyone that I wanted to do it later in the season.
Let me know how it goes, Tony. I'm working a short day today.
So, I'm not available to help right away - but the welder loads into the truck easy enough if you need it welded. Lemme know.

I'm not too crazy about using heat because my fuel line runs about 3" away. For now, I'm going to run out and get a pipe wrench and try to hold the bolt still as I pivot the pump...hopefully that'll do the trick.
Thanks for all your help guys! I'll keep ya posted.

The bolt shouldn't move
Hopefully the threads in the block are fine ....
and the bolt is rust-seized to the inside of the pump.
Just wrap the hoses and belts loosely with a few layers of aluminum foil,
and heat the pump. They will be fine.
BTW - you have the rubber line from the pump.
I'm trying to dig up parts to fix mine to steel during the event.
If I find something, I'll get a couple sets - should be fairly cheap.

Now I hope I can pick up a GM Performance parts aluminum water pump locally tomorrow or at least a stock GM pump while the original goes out for a rebuild (yes, I'm an originality freak...but one day I hope to replace the LT-1 w/ a ZZ383). I have a new BOSCH unit ready to mount, but think it'll go back to Pep Boys.
So I think I should be all set for Satuday! I just hope it all goes well from here.
Dave, BTW, the fuel line is steel.
Thanks again,
Tony





tony...this is the DARK side calling scrap the original stuff come to the DARK SIDE our Force is strong and we have many....
but it won't force you to wear seatbelts and keep yourself from dying.
(You'd have to have seen episode 3 for that to make sense)
That's great news Tony ... sorry for misreading your picture.
The steel line has same color/texture as the hoses.
The LT-1 line is one-of-a-kind and pricey if I recall ... so we will leave it be.
I like original parts - due to the quality ... replacements are typically crap.
If I can, I refurbish the old ... at least when a better upgrade is not available.
Looking forward to this weekend ... looks like the weather might cooperate.
Also, I am using the BOSCH pump...too many problems with the aluminum version...
