rusted bolts

I've used liquid wrench with fair results. We getting ready to lift the body off the frame. Has anyone used a better product for loosening up bolts that haven't been turned in 40 years?

PB Blaster.

Mix Auto trans fluid with Kerosene.

Either of those two will work about the best.

Don't listen to me, what do I know? I've only been doing this for 30 years.

I have to second the PB Blaster.

I asked this same question over at PT.com a month or two ago, and used a Poll with similar products as choices.

PB Blaster - by a landslide!! (and btw, WD-40 was waaay down the list, Liquid Wrench also at the bottem)

Hey Ben,
I have used every NEW, "Hot set-up",Best stuff EVER,over the years, and all I can say is I have YET to find ANYTHING that out performs KROIL. Alan mentions kerosene and trans. fluid and KROIL is pretty much that. I also recomend to let it soak for a couple of days. Another thing, "rattle" the nut or bolt with a hammer will help getting penetrating oil into the threads. If ALL else fails, heat it up and let it cool a bit then try loosening it again.

Acetone and ATF, 50/50 mix. You'll find this on the web as being better by MILES than any commercial product.

I've had nothing but success with PB and KROIL as well. I'll stick with PB... it's never failed me.

I've been soaking my body mounts for months now... hoping that one day soon I'll get the darned time to actually change them!

An old body shop trick is to tighten the bolt just abit then loosen. (breaks the rust)

OK, I'll throw my 2 cents worth in here. In my opinion, the best product I've personally used is GM Rust Penetrant and Inhibitor (p/n 88862627). It was originally developed for freeing up stuck exhaust manifold heat riser valves. If you've ever dealt with one of those, you know just what "stuck" means. I have used this stuff on exhaust bolts, body bolts, and basically any fastener that will rust badly and have had a very high success rate. The key is use liberally, let it soak (patience is a virtue here), then use HAND tools. Air wrenches are a techs best friend except in the instance of rusted bolts.....then they are bolt breakers. You can buy this over the counter at any GM dealer.

ASE & GM certified master technician, and no, I don't think I know it all.

I imagine this is an ever shrinking club that not many of us are in anymore. My '64 Chevelle had one, it always leaked. I wound up welding it in the open position and disconnecting it. Never had trouble after that!
