Broken water pump bolts

When trying to replace the water pump on my 92 lx 5.0 I managed to
break 3 of the bolts, 2 of which are deep inside the timing chain
cover.

These bolts are pretty long, and its hard to tell if they pass through
the timing chain cover and thread into the block itself, or if they
thread into the cover.

I would like to buy a new timing chain cover and new bolts, rather than
try to bore out the broken bolts. Do any of the water pump bolts go
into the block? If so then this solution won't work (although with the
cover off the bolts would stick out and maybe I can unscrew them with a
vise grip or something).

thanks

Yes. Some of the bolts go all the way thru the cover.
I think there are 4. They are the ones at the extreme left and right. They
are above and below the water exit passages to each bank of cylinders.

Usually, these bolts will corrode into the aluminum of the front cover -
*usually*.... You shoul dbe able to get the front cover off and the
reaminder of the bolts should come out fairly easily....

Inexperience has cost the original poster a good deal of frustration.....
try to avoid having it cost too much money...

What could have been done that would have avoided the bolts snapping
off?

I put "Neversieze" on my bolts when reassembling parts. If the bolt in
question needs to have a locking compound on it then I use the
locktite on the last 4 or 5 threads and neversieze the remainder of
the bolt.

I didn't think the original poster was the person who put the pump on.
He was just the person taking it off.
