What is the best way to lossen/remove rusty frame bolts?  I'm having a heck of a time with some of them.  I've been sraying them with a solvent, but still no luck.  I'm worried about breaking them so I've resisted putting too much torque on them.  Any tricks would be greatly appreciated as I plan to try tackling them again this weekend (between football games) 

The best solvent I've found is AERO KROIL by KANO LABS. If it's a nut you can use a nut cracker. If it's a bolt if the solvent dosen't work use heat & tap with a hammer then spray solvent. Sometimes you migh do this process for a week. If you break it off drill & use EZ out. Last resort overdrill & use heli coil. There's reaslly no easy way, but the heat & solvent work 99% of the time if you take your time.

I agree with Alan.. I use this too.Just give it some time  to work...  This info may not help now... but whenever I put a nut or bolt back in I use a "antisieze" compound so you shouldn't have the same problem next time...

Thanks Alan and Ray!  Couple of follow-ups...what is a nut cracker?, and where do you get "antisieze" compound?  Its that what it's called or is there some specific brand name I should be looking for?  Again, really appreciate the advice!

 

Anti-Seize Lubricant by Permatex is one company. Boaters have used this stuff for years & I also use it in any sitsutation where water will be involved. You will soon learn that when you get it on your hands it's hard to come off. Put it on my wheel bolts when I first get a car & never have problems.  A nut cracker is a tool that goes over the bolt & has an triangle like piece that when you thighen it will go into the bolt & crack it. Any parts store has then in different sizes & styles to work in all but the tightest situtations. Good luck on your project.

Ken Styer (kstyer) pointed me at his favorite solvent.  It's a GM product that the "old guys" call "Heat Riser Lubricant".  It works great!  I know there are other threads that talk about this but I'll get the GM part number (and current name) tonight and update this reply.

Anti-seize stuff is available in spray or paste form at all the local parts outlets I've been in.

A nut cracker (nut breaker/nut buster) should be available anywhere mechanics tools are available.  It is a simple tool that slips over the frozen nut and as you tighten the wedge it splits the nut.  The bad news is the nut is destroyed - the good news is the bolt is now free to slide out.

(OOPS - looks like Alan is a faster typer than I am!  Sorry for the duplication.)

I prefer the brush on and a bottle or can will last quite a while...

       

Anti-seize is a must. It will only help you out or the next owner. It is also a good idea to use a tap and die to clean the threads before putting a nut or bolt back in use.

i always use wd40  let it soak for some time.(for days and spray a few times again) . .. atleast i thought it was one of the best products around. .. so i am reading with interest what other products are recommended
