Sheared off bolt

[Tracker1]

Wondering how to come at this to get it out. Or if I do anything at all. Good 660 thermostat housing on a '70 LTI intake...oy

Any ideas? Thanks

Simple. The bolt is most likely frozen in the housing not the threads. Let someone that has experience with these situations deal with it.

I live on an island off the east coast of Canada - most here want to attack it with a sawzall. it's all on me. If I may reference your signature quote by Faber - "knowledge is good". I need knowledge. Thanks.

Can't you use an Easy Out for that?

Can you get the other bolt out, lift the t-stat housing off the intake and then after soaking the threads on the broken bolt with penetrating oil use vise grips to remove it?

No, the sheared off bolt is holding the t-stat housing into the intake

Hit it with WD-40 and let it sit for day or two. BBBenny

Been doing that for a couple months Benny, yup. I haven't been considering heat or drilling in this situation Jason. But I think I may just have to sacrifice that 660 [img]<<GRAEMLIN_URL>>/frown.gif[/img]

I do have any easy out, just been hesitant to use it...

So the short bolt is removed or still in the housing? If you can get the short bolt out I would try to rock the housing clockwise and ccw just to get some movement (using a ton of penetrating oil and a wooden or rubber mallet)

I'm confused. The t-stat housing isn't threaded - those are clearance holes in the housing. Remove the other bolt. Work the housing loose and remove it. Then remove the sheared off bolt.
