How To Extract Broken off Bolt EVERYTIME

How to Use Screw Extractor Remove snapped off bolt from engine

You don't say which vehicle? The psp is fitted in a similar way as the alternator, that is, either two bolts underneath or a long through bolt to mount the unit to the engine, and then a third bolt to adjust belt tension. Else, the unit is bolted rigidly to the engine and the belt is tensioned by a separate pulley.
However, if you are going to take the unit to a garage to replace the broken pulley, why not let them do the whole job?

Shouldn't be to hard. Find where the sleeve is connected to the side of the engine. Usually one bolt. Remove the bolt. Remove dipstick sleeve from your engine. Then you can use a wire hanger from the other end to push it up. Or down which ever is easiest..

The first thing you need to do is to think about why the bolt broke in the first place. Was it being turned in the wrong direction? Or was it just really corroded? I've seen mechanics who've been in the buisness many years turn a bolt the wrong way. Anyone can do it. Is any of the bolt sticking out? If so get some "KROIL" it is a release agent of the highest quality. If you can't locate Kroil brand then use something like liquid wrench and spray the bolt right where it goes in. Let it sit then spray it again. I would probably heat the block right next to the bolt with a heat gun if I could do that safely (ie nothing will catch fire). The heat is to expand the junction between bolt and engine block. Then spray the KROIL on the bolt again. Grab the end of the bolt with vicegrip locking pliers to get it out. Make sure to get them on there as tight as you possibly can, and make sure you're turning it the right way to get it out. If the bolt is broken off below the surface you should still spray it with KROIL, but you'll need to drill a hole down the exact center of the broken off bolt down far enough to allow an "easy out." An easy out is a special tool that that has super coarse opposite direction threads that turns in tighter into the bolt as you use it. As you try to turn the easy out further into the bolt, you're actually unscrewing the bolt from the engine block. You'll want to make sure and measure the length needed for the replacement bolt, and take a piece with you to the store to be sure to get the right thread - metric or standard - coarse or fine. And be sure to figure out why the bolt broke in the first place. Good luck

I had this happen to me I heated the broken bolt with an acetaline torch heating only the broken bolt red hot .than I let it cool down. that broke the rust free. I than drilled a small hole in the center of the bolt. I than drilled a larger hole . I found a good quality easy out put it in my drilled hole and with alot of mussle got lucky enough to remove it.It worked for me was not fun.Hope it works for you if so leave me great feedback

Drill the bolt out with the appoint size bit and use an ease out to extract it. Is the bolt broken flush with the outside of the engine or is it recessed??

Remove the lower four bolts (hope you did not lose any broken pieces into the trans.) and holding the part in a vice, remove the broken bolt and the nose piece that broke off. You may have to use a little extra force to get the new special bolt all the way in due to some damaged threads; put some sealer on the gasket and refit

If it's bolts that are broke you can get some E-Z outs that you can drill into the broken screws to get the screws out. These are used for broken bolts in your engine but you can get extractors to help take out almost any size of bolt. You can also ever so carefully chisel off the head of the bolt and try to pull the dash out and then use some vice grips or a smaller socket to pull out the damaged bolt heads. I wish you the best of luck.

you need to drill the bolt ou and use and easyout to get is out

yes it should be a gasket
