I was changing the water pump on my 92 5.8, using 3/8 drive ratchet and socket, and I broke two of the bolts off. One is sticking out far enough to get a small pipe wrench on it. The other is broken off about 1/4 inch into the hole. This is the first time I ever broke a bolt off. Does anyone have any suggestions on hoe to fix.

Do those bolts go through the timing cover?? You might beable to take the cover off and get on it with vise grips or the pipe wrench. If it goes straight into the block you would have basically 3 options.

1) Heat it with a torch and use an ez-out on it. I've never had much luch with an ez-out though, it seems they are very brittle, yet when you try and drill through a broken ez-out you find that it is made out of the hardest material known to man

2) Drill and tap, works good but takes some time. If you haven' done very much of this i don't recommend practicing on your engine block.

3) As a last resort i've had to weld studs onto broken bolts.

I have had some luck with left-handed drill bits, but my guess is that your bolt is probably too tight in the block for one to spin it out.
I bet the bolt is too far in to drill and tap, unless you have a bit and tap long enough to go through the timing cover and then into the block!
I would have to agree with ford4ever, and say just take the timing cover off and then get them out. Also- Never a better time to install a new Chain and gears

 

Try the extractor or the counter clockwise rotating drill bit first. Use a good penetrating solution (PB Blaster is good stuff) and soak it down good.

Depending on which bolt it is, you may be able to get by without it. Extra gasket compound and curing time might do the trick. Personally I'd get it out even if the timing cover has to come off, but I've heard of several people doing it with one or more sheared off bolts and no problems.
