I dont remember if i used red or blue loctite on my converter bolts last time... i didnt see any loctite on them when i pulled them out i know i used some...

thanks in advance

 

I use blue. Don't use red.

 

I use red...lol. I don't use the blue on anything larger the 1/4" drive ratchet material.

 

Isn't red supposed to be a permanent bond?

I've read you have to heat it way up with a torch to get them out.

 

On very large fastners, you MAY have to heat it, usually don;t have to though. Use it everyday at work. You learn quick in the marine industry to use the fawk out of loctite!

 

Let's hope it's blue that's what is on my converter bolts red is suppose to be permanent bond

 

I use red on anything thats not supposed to be taken apart...head bolts for example...unless they're supposed to be oiled like in some engines. Blue on anything that may have to come apart due to gasket replacement, so like valve cover gaskets, oil pans etc.

T/C bolts aren't really supposed to come out, so I would generally put red on em...but if you want to remove the converter for any reason, blue is fine. I've put lots of engines together using nothing, and 100K plus later the bolts were still in there...so really blue will be more than enough.

Having said that....I've pulled a tone of things apart that used red loctite on them, using nothing more than a beaker bar...it's not that permanent on anything you can fit a normal size socket on.

 

Red is high strength, but still removable with application of heat. Make sure you use heat when removing red loctite from aluminum threads or you will damage them. Red is good for use inside engines and such where there is oil.

There are two types of blue loctite. One is for use in both oil and not in oil. The other is for not for use in oil or it will be worthless. I just keep a bottle of loctite 243 (blue) which is good in both and is oil tolerant. Loctite 242 (also blue) is not for use in immersion in oil (ie converter bolts, inside engines, etc) Note, loctite must still be completely dry before adding oil to engine or else the loctite wont work.

 

Oops...I use red on pretty much everything!!

 

Ok blue it is... just out of curiosity, who don't use loctite on their bolts?
