Re: thermo housing bolt broken-- help!
As you start to remove the bolt, be sure to turn it back and forth as you remove it. Rust and metal will want to gawl up the threads and if you continue to turn it counter clockwise, the ball of junk will get bigger and bigger until it siezes again. By rocking it back and forth you break off the debri and keep it out of the threads. Good luck. If the grips don't work, you'll end up having to drill down the center of it and use an easy-out or something. Trick there is center punching the bolt and drilling down the center of it. Sometimes a small socket will help you center up on the bolt with a punch. Start with a small bit and size up as needed.
