You have the procedure down! One or both of those bolt holes end in the water jacket and will actually leak coolant when removed, so you might as well drain the system. Once you get the broken piece out, chase the threads with a tap and put some plumber's grease or never-sieze in the hole and on the end of a new grade 8 bolt. Then be sure to use coolant with anticorrosion protection.

Hello Everyone...
Well, Im going to have to assume that this is a problem not so far fetched that it hasn't happened to someone here before. It is as follows, my pulley which has the belt connected to the fan and water pump was in need of adjustment. In loosening the bolts... "Drum roll pls... " one of them being very tight broke off. The other will as well when I tackle trying to remove it as well as far as I can ascertain. The bolt was rusted and led me to assume it is going into the water pump assm. the break happened at the end of the threading. I only know this as I removed the identical bolt from another 413 I have.
I started removing the radiator bolts and stopped out of frustration. I guess I need to hear some advice on what the best procedure would be to follow so Im not doing unneeded work for which I have become famous for lately. Best I can tell to remove the bolt Im going to have to remove a number of components, radiator, trans cooler, A/C radiator, fan, the balance of the pulley and the water pump to access the bolt to drill it out.
Am I correct? Best of all here, is going to be the most reliable method without ending up with a broken easy out added to the mess. I have been applying penetrant to the area, I don't feel this will help too much as it has been over a week and the other bolt remains tight and while I am attempting to remove it I can feel the initial twisting that we all know about happens before the snap...
This is the engine I will be rebuilding soon, but since Im knee deep doing a frame off on my MGB Roadster and rebuilding a cushman engine I think I will elect to hold off or try to for a few months.
As I mentioned this obviously has to have happened a lot before since that bolt goes through the water pump. I hope at least...
