Red Loctite
Anybody know of a way to remove a bolt/screw that was installed with red loctite (should have used blue my mistake). This is a set screw on my steering column u joint (need to remove steering column).
I don't think heat will work just because it's near the exhaust manifold and it acts like it's welded in there. Thanks

Depending on how accessible the area is, heat, like from a pencil or bottle torch, is the answer. That will crystalize the loctite. Then, while still hot, a few smacks with a hammer will break the bond and release the set screw. The bigger problem with a set screw is that there isn't very much purchase to turn it. Keep at it. Have patience. It will break loose.
The bad news will be if the heat dries out the uni joint. Lube it well before reinstalling everything.

Ok thanks. I guess I'll try more heat in the morning after I go to sears and replace the allen wrench that I broke trying to get the set screw loose.
All of this because I'm changing over to a CPP firewall mounted booster and master cyl (all ready have a firewall mounted booster and M/C but my brakes are like a on off switch so thought I would try this (found another way to waste more money)) and where they want you to install it happens to land right in the middle of my wiring. I'm not moving the wiring so I guess a new mounting bracket is in the future.
Again thanks for the info. Chuck

Before you go crazy with the hot wrench, I really did hear on another forum that an application of red loctite works as a solvent - just hearsay, but if it works...............and it can't make the problem worse. fwiw

red locktite requires a fair amount of heat to remove, I don't remember the exact temp but it's higher than you'd want to hold or that your exhaust heats it to. Use a propane torch to heat.

250 C. is 480 deg. F.
I've used it for years on flywheel bolts and such, clean threads, etc. An impact wrench takes them right out without heat. They don't ever come loose so I assume it's working. I could see where it would really lock up a small setscrew.

Teachers are still telling kids that the complete switchover (in the US) to metric is "around the corner". That's what they were telling me in HS 30+ yrs ago. Must be a gov't run program to switch...

Heat worked. About 5 seconds of heat from a propane torch and they turned out like nothing was ever stopping them (snapped a 5/32 allen head wrench/socket on the first one) anyway thanks again.
I think I will use blue next time.
