Well it was my bright idea to try to try to replace my thermostat to fix an overheating problem. I got both bolts out and as i was tightening the lower bolt it snapped off flush with the lower intake. How can i go about getting this bolt out. I cant get straight access to the bolt to drill it out i dont think? Do i have to get the upper and lower intake removed and have the bolt drilled out? Is there any other way?
Thanks

If its flush you have to be able to get a dril straight inline with the bolt to use an easy-out if there is a nub sticking out take a hacksaw blade and try cutting a slot in to top of the bolt and using a screw driver to unscrew it

Unless you have access to tap it in the removal directon, with a small chisel, you pretty much have to remove the intake to get to it. If you have access to a good specialty welder, you can get a short bolt or nut or extension welded on the end and turn it out, but that's a long shot.

If you can get a drill on the bolt at all, try a left hand drill bit. Sometimes the effect of turning that direction with the heat will free them without having to drill a hole perfectly in the center.

Real long shot would be taking a Dremel or similar tool with a cutting wheel and trying to put a slot in it.

Been there, done this. A 20 minute thermostat change on my Bronco turned into an 8 hour nightmare, when I broke 2 more bolts on the intake removing it.......

And then found a corroded spot between the rear water passage and the bolt hole......

This escapade lead to me giving up old outboard motors also. If they had 3 bolts, 2 broke every time I touched them.

Im going to try cutting a groove in the bolt. I didnt think of that and i can cut a small groove in the tstat cover too right? If it isnt deep then i can get a screwdriver bit in there. Would taht be a good way to go about it?

Have you ever seen or used a 90 degree drill. That should get you your angle if you want to drill it and ez out it. I would suggest a left hand bit if you can find one, the bolt might just spin out once you start drilling it then.

You can rent angle drills. I had a head bolt break off in the block and had to drill and helicoil the hole. Dont use an EZ-out. My head bolt ordeal would have only taken an hour instead of 2 days. The EZ-out snapped off in the bolt, so I had to use a die grinder to grind it and most of the bolt out.

I think like others mentioned the 90* drill would be a good bet . You can do the method you mentioned and even if you damage the thermostat housing it is not an expensive replacement .

Good Luck!

It's a tool, you drill out the center of the bolt and then depending on the type of easy out you twist it in (left hand thread) or tap it in with a hammer then turn out the remains of the bolt.

Easy out is a dill bit that reverses the bolt to it can unscrew it. I plan on buying a 90* drill attachment and a bolt remover like this. Tell me if its the right kind i should use. http://www.sears.com/sr/javasr/prod...Bolt-Out,+Taps+&+Dies&vertical=TOOL&ihtoken=1
