Re: broken thermo housing bolt
that sux same thing happened to me once
#1 get a center punch
#2 make sure you center your drilling VERY IMPORTANT
#3 start with the smallest bit you can DO NOT line up the bottom of the bit (where the swirls stop) with the chuck, it will be a weak point and brake.
#4 lub the bits with wd 40 of something when drilling
#5 be very careful with the tap go 1/2 right then 1/4 back to the left.DO NOT SNAP TAP that what happened to me.
good luck i hope this helps

Re: broken thermo housing bolt
is the rest of the bolt sticking out of the manifold ? you said it broke at top of thermostat housing . if so , your lucky . if enough of the bolt is sticking out of the manifold to get channel locks or vise grips on . wire brush all rust away , soak with wd-40 , pb blaster , good penetrent oil . take your time , tap bolt stud with hammer while soaking with wd40 . go get a cool one come back out . few more taps and wd40 , try channel locks . still no go apply heat [ propne torch ] to manifold bolt area . wd , tapping , heat , channel locks , should do it . LOL
