When I purchased my 73 dart I noticed the previous owner tried to take out a bolt from the alternator bracket. He heated the bolt head and mushroomed it. Of course when I tried to get it off the bolt broke. I have sprayed it down with penetrating oil for weeks and tried to get a crescent wrench on it but it hasn't worked. Any advice would be greatly appreciated.
Thanks, Bandman
PS I tried to post a picture but I can't because of the size of the picture.

Remove the bracket if you can.Then you will have a good piece to grab with a small pipe wrench or vice grips.Try heating the bolt with a propane torch then hit it with ice water.It shocks the threads.Id say it siezed in the bracket.On assembley use antisieze.Rocky

Grab a file & file the rounded nub to a nice square so you can get a good TIGHT grip on it with some vice grips

That and Ive got some out by first trying to tighten them just a bit.For soem reason it seems if you try and tighten it just a touch most will back out after some heat and penetrant.+As for a water jacket use a bit of liquid teflon on the threads and anti sieze where it goes thru the cover.Too many gald themselves to the cover.Rocky

Just did this yesterday to an Engine that someone brought me to build. Mine had more stud sticking out but no matter what I used it wouldn't budge. I could see the coolant corrsion around the hole in the timing cover. I stripped the rest of the front of the motor apart down to a bare cover. I used a map gas tourch to heat the cover around the bolt area until I could start to carfully pry the cover off the bolt using PB blaster. I did have to apply heat again as the cover only went so far, then I tried the pipe wrench again and was able to screw the bolt out---but it was still stuck in the cover when I finally got the cover off. When I got it all off a swift hit of the hammer drove the bolt out of the cover. Took me about 40 minutes total to do all this---but the engine was on a stand.

Try WD40 penetrating fluid.Ive been using it and its a lot better than PB.We used to get some stuff from Zep that was the best at the shop.IIRC Ive seen it on Ebay.Rocky
