Followed instuctions up to the point of tightening the nuts to the thermostat housing bolts and one of the bolts broke off. Have a new bolt but can't find how to take out the broken and replace with the new one. Can you tell me how to do?

What it does is grabs onto the stud and with a attached rachet wrench, you can twist it off... or you can use a Vise Grips. Here's the link to the Stud Removal Tool ... it's less than $10:
