How do I use blue Locktite?
 

I know this sounds like a weak post, but there weren't a lot of instructions on the tube.

1- use wire brush to scrub off the old blue micro encapsulation (for say, a caliper bolt)

2- put lockitite on

Then what???

Let it dry? (doesn't seem to dry too fast)

Torque the bolt into position? (seems like the wetness of the locktite would make the torque spec inaccurate)

Not worry about it and just let the old blue crud on the threads do their thing?

Anyone have any thoughts?

thanks

Screw it in and torque in to spec and you are finished.

Loctite red and blue are Anerobic in their properties in that they dry in the absence of air. Just dab a very small amount on the bolt and tighten it up! They do their job after sitting in the tiny crevices between threads drying without air.

don't ever use RED locktite unless you plan on never taking off fastner in this century.............

If I am not mistaken the red will come apart when you apply heat.

Yes that is right heat will soften red locktite I learned the hard way when I changed the transaxle in a friends Plymouth Voyager, as some one in the past had removed it and used red locktite on every bolt in sight when reinstalling it..........

BlueSurf,

Adding up all the good advice in earlier posts, the proper procedure requires buffing the old stuff off, cleaning both sets of threads of oil and grease, applying some BLUE loctite to the bolt or screw, and tightening it down.

I use a wire brush on an electric drill at low speed to clean all bolts whether they are to have loctite or anti seaze grease on them then I clean them with carb or brake cleaner.I ordered a lot of front end parts from Fastlane this summer and some of the parts like the track rod joint came with new bolts for the rear cap and they had perfect pre applied blue lock tite on them of course it was cured anybody seen it done that way before?

William,

Yep. It's perfectly normal. My guess is the loctite liquifies as you heat the threads while tightening. Used the same bolts myself. Ain't technology great?

Here's a somewhat unrelated repy:

I used to know the actual iventor of Locktite. He appeared once a week on a television show I worked on about helping capitalism develop in Russia. ("Skunk" Baxtor, from The Doobie Brothers also works in that cause.)

Nicest man! Like Sam Walmart, he was a muti-millionaire (or maybe a billionaire), yet drove himself to the studio in some old beat up '80s Dodge Omni or something similar. You'd figure he would have a nice Mercedes!! :) He passed away a few years back.
