Broken Bolt removal

["Tim Hulse" <thulse@xxxxxxxxxx>]

I dont know about the one that is broken off that far in but I would not be heating the bolt that you still have to remove. If your heating the bolt in will expand then you will break it also. I would see about a electric inpact that you could set on low so you don't twist it off and see if that might help. If you cant use easy outs on the broken one I would take it to the place you mentioned.

Good luck

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...
