IMO, heat is a last resort and it had better work because often if you heat a fastener that hot and don't get the fastener out, you will have nearly welded the thing in place. I think I know the bolt you are referring to and it is a rather large bolt. Start with a centre punch and a very small drill bit and drill a hole in the centre of the bolt. Then work your way up to larger bits until you are the correct size to use your "easy out" bolt extractor. The easy out in conjunction with a good heat source should give you the desired result. Having used a propane torch for this purpose I can say that the heat they provide is minimal at best. Trying to heat an engine block with that torch might not be enough. IMO you should try a more agressive heat source...oxy/acetelene would be perfect. (of course that is hot enough to melt metal so watch what you are doing) ----- Original Message ----- From: SFSurfDude@xxxxxxx To: mailing-list@xxxxxxxxxxxxxxxx Sent: Monday, March 15, 2004 9:15 PM Subject: IML: Broken Bolt removal Hello... I am attempting to remove as mentioned before a broken bolt which is snapped off while loosening it. It is broken at the top of the threaded area on the pulley bolt for the fan. It is holding the left side of the water pump in place. Bolt is approx. 4 inches in length, 3.60 of it I have in hand. Obviously to get to that broken threaded area in the block I have removed all components in the way etc. As I feared initially, the other pulley bolt which is still intact looks as if it is due to play a repeat preformance of the first bolt. I have tried an entire can of penetrant over a two week period. I have applied propane torch heat to the exposed bolt which s I mentioned is still intact. Nothing, no results. period. I am in the high desert, not within the LA Valley where I could take the car in on a 40 - 60 tow to a place that does the removal by zapping the bolt away in bits, forgot the name of the process. So it looks as though its "old school". Along with my fire extinguisher I fearfully heat this bolt inches away from the fuel pump. Its smoking like crazy, well at least the first 20 minutes it was. I have also hammered on the end of the bolt as my experience has shown that works from time to time. Even the old tighten it slightly, it doesnt budge. Any suggestions? Maybe weld the pulley till I do the rebuild, Nah...
