by the liquid wrench when your at sears.

 

Ive been told brunettes are better than blondes, go figure

 

when you use heat, you need to wait for it to start to cool down

 

I found some Liquid Wrench in my cabinet and have already sprayed it on. I'm off to Sears now- thank you again. If this works, I'll UPS you a bottle of your choice, I just polished alternator, bracket, air pump, and the TPI. I REALLY don't want to pull the intake. PS I like blondes better but usually end up with brunettes! Go figure!!! Thanx again!

 

how did it go?

 

I'm going to a bigger Sears in Tampa tomorrow afternoon, my local store did not have it. Thanx for asking, I'll let you know.

 

I'm talking from a lot of experience (unfortunately) about broken bolts, been twisting wrenches on cars for 25 years and the best way to get it out is to grind the top of the bolt till it is flat with the manifold, use a good sharp center punch and punch the bolt dead center. THen use the method by which we call step drilling. Start with small bit, say like 1/8", then redrill again with a 1/4" and so forth. Be careful not to go to big, since a 3/8" bolt is the size of the bolt in the housing. NO bigger than, say, about a 5/16" bit. Then tapout the hole with a 3/8 tap. Stuff a rag in the thermostat hole to keep aluminum from getting in the intake. Be patient on drilling hole, since you are drilling steel in an aluminum hole. Try to keep drill as vertical as possible on the first hole you drill, after that, it is easy. You will feel when the drill bit passes through the bottom end of the bolt. Using easeouts can be more troublesome, especailly if you break one off in the hole, because they are made of hardened steel. Very hard to drill out. Good luck. [8D]

 

super mech, wouldn't you at least try the bolt out, i used it on a snapped off Land Rover brake calliper bolt, which was torqued way harder than a thermo bolt.

 

That was a just in case response, cause you where asking about an ease out. Usually, when you galled a bolt in an aluminum manifold, that is what u have to do, so good luck.

 

I tried the bolt out, I tried to heat the aluminum with an o/a torch, I tried an easy-out, I tried to weld a nut on the stud, ended up drilling it out. I will be tapping it 7/16ths tomorrow. Couldn't find a bottoming tap, they only had plug taps. Thank you for all your help!!!
