Small tip on a hot wrench and apply heat directly to the bolt head....get it red hot if you can and put a 6 sided socket rather than a 12 sided socket on it and break it loose. If it is really stuck it may break off so be prepared to drill out the bolt and remove it with and easy out.

Tighten it a little before trying to loosen it. If you can get to the threaded end, apply PB blaster and let sit over night. If you don't have access to an acetylene rig, a propane torch can be used.

Removing rusted bolt basics
One of the first jobs I ever had was at a shop doing full on restorations on vintage Fords (we specialized in model 40s 1933-34). By boss taught me MANY things I use every day. One of them was the best trick for getting rusted bolts out that I have ever tried.
You need your torch with a small tip.
Take the torch and make a perfect flame like you are going to weld. Heat the bolt head up till it starts to turn red. (If the bolt is already broken off you will need to saw a grove to use a flat blade screwdriver or have enough to grab with locking pliers) Then quickly cool it with a squirt bottle of water. Repeat, heat it, then cool it. Do this a number of times and the bolt WILL turn right out. If you can, heat the nut around the bolt right before you try turning it out, BUT DON'T HEAT THE BOLT. This will expand the nut from around the bolt. I have did this on Model A door hinges, if you are not familiar with them, it is a 5/16 bolt with a little flat blade screw driver head! A ridiculous design that rusted in to tight to remove around 1950! You can imagine how hard they are to remove in 2000. I have did these with total success, only needing a regular hand screw driver about 99% of the time.

The way I figure the heating and cooling expands and contracts the screw breaking it loose from the rusts grip.

If you can get an impact wrench on it, use light to moderate power and let it rattle for a while. PB or AeroKroil is always the best way to start.

Rusted nuts on corviar manifold..

I've just purchaed a used Corvair engine that probably has never had the nuts removed from the manifold at least since from 1965. they pretty much look orange and fuzzy. I've been soaking them in penatrant. Is there any brand in particular I should be using. so far... they are still tight. If I heat them should I heat the stud or the nut?? I dont want to hurt the threads in the aluminum from turning to tightly.

:confused:

removing stuck bolts

I have had good luck with the heating up and cooling with water trick and also with heating the bolt and then melting wax down onto the threads. Both seem to work well. :welcome:

As cletis said, PB blaster and time work in many cases. It's a lot less drastic, too. I've had them go from unmovable to easy after several treatments. Spray 'em, try 'em, if nothing moves at all, wait and repeat the next day. If you ever get it to budge the least bit, spray and wait again. The tiniest back and forth movement will eventually allow the penetrant to do its job. Be as patient as possible, if you intend to salvage the fastener or don't want to heat the area.

PB blaster in addition to the heat cool trick. I have removed a great many rusted bolts over the years and it is simply amazing how deep that stuff will penetrate into rusted threads. The key word here is patience, don't rush give these things time to work and whatever else you do don't force it and in most cases you will be rewarded with success no matter how hopelessly rusted it appears.

PB blaster :thumbup:

Best way

The best way that i have ever used is get some candle wax or any other type of wax and heat it up and just drip it onto the stuck bolt work really well. But even a better way for doing that is drip the wax on either side of the bolt then from the other side heat it therfor the was will run down the bolt following the threads and that bolt will come out like it was brand new. :)
