Broken Bolt removal

[<rls9151@xxxxxxxxxxxxx>]

Hello,

 Does this bolt secure the fan and pulley to the water pump or does it secure the water pump to the water pump housing/engine block?

 If it is the fan/pulley bolt, just replace the water pump and install new bolts. If it is the water pump mounting bolt, heating the bolt will do no good for you. You must heat the block around the area where it screws into the block. That will make the block swell around the bolt and help loosen it. Then, while hot, spray some penetrant on it. Heating the bolt will make it swell up tighter in the hole.

 If you use a tapered screw extractor, remember "the tighter and deeper it goes into the bolt, the more it swells the bolt in the hole", even though it will grip more. Snap-on's 'Blue Point' series tool line has a screw extractor set that uses a straight rod with a spline that drives into the broken bolt and then a nut that slides down right to the broken bolt. I have used these and they work excellent, even where a tapered extractor won't. They even come with the correct size drill bits as well.

 If this is a 413 engine you can take the entire water pump housing off with the pump and carry it to someone to have the broken bolt professionally removed. That would be less expensive than towing.

 Also, soak some rags in water and cover the fuel pump and lines to keep the heat off of them. Rewet as needed to maintain safety.

 I hope this helps.

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...
