are you going to drill the bolt all the way out or are you gonna drill a hole and than use an 'easy out'. thats what i would do. just talk to someone at the hardware store and ask them what drill bit would be good to drill metal...?

Im guessing u broke the heads off? If so, remove the water pump and use some vise grips on those broken bolts. The other way is to use and EZ out tool. Basically a drill bit with reverse threads.

You can always dremel a little notch out of the top so that you can just get a screw driver and get it out. This works but may not be the best idea if the bolt is really in there tough!

Yea i would agree with what everyone else has said, but EZ outs seem to work the best for me if you can get to them. use some good rust penetrating oil too and let it sink in before trying to remove anything, this should help out a lot....good luck man

I broke a bolt yesterday that goes to the water pump. Lucky for me it's one that's up top and doesn't go into the block or timing chain cover. Should I still use an ez out or just drill the hell out of it?

An EZ out would be the preferred method...Is the bolt sticking out the back of the timing-chain cover? If so, you can cut the bolt between the cover and water pump, an continue to thread the bolt though until it removes itself.Legendary said:

Well I didn't want to take the water pump off. I was adding an March alternator bracket and it required that I removed the bolt. You can still see it poking through the back.

How to use an EZ out:
You'll need - a set of EZ outs, Vice grips, hammer, drill, drill bits, SAFETY GOGGLES.
Drill a hole into the middle of the bolt, leaving enough room on the outside of the shank so it wont break, crack, or split. If its a 1/2in thick bolt, youll want to use a 1/4 in drill bit...make sense? Once th hole is drilled, no deeper then 3/4 inch shouod be needed.Secure the EZ out into the vice grips flush with the teeth of the vice grips, not stright foward, just like a set of plyers. The EZ should go into the hole deep enough, but not bottoming out. Then, using the hammer, tap the EZ into the hole unitl it goes no more, now continue to tap/hit the ez out/ vicegrips while turnin tghe ez out/ vice grips in a counterclockwise rotation. The bolt should break loose and spin out. If the EZ out isnt gripping, hit it harder, and rotate slowly. DONT break the EZ out in the hole! Its ok to drill deeper if needed, but try not to widen the hole too much.

How much is poking through the back? Grab that little end with some vice grips and unsrew it.It should unsrew enough to grab it on the waper pump side and continue to unsrew it. good luck, be creative, youll figure something out.
In case u didnt know....vice grips are a very essential tool.

I had 3 bolts break off inside the block when I was removing the waterpump/timing cover doing my engine rebuild. So I had to have the machine shop get them out while boring the cylinders...sucked. We thought we had to find a new block cause they almost couldn't get one out
