Loctite Red/Blue?

[koolio]

Never used the stuff, but there is a first for everything.

I usually use spring washers + copper grease.

I believe on other bikes I've had, I've removed bolts and screws before that had a softish blue material on threads making it harder to screw out I understand this is loctite?

So question is this, I want to secure nuts and bolts on the engine as well as reduce corrosion. The engine is made of an aluminium alloy and the new bolts and nuts I have are stainless steel.

Should I use the red or blue loctite? I'm worried the loctite will burn under high heat.

Is copper grease advisable instead?

My plan was to loctite the bottom of the threads and copper grease the rest.

Would appreciate your thoughts and what you do on your bikes.

Loctite 272 is rated for High Temp applications according to the website.

The stuff will be fine on everything bar exhaust studs.

I wouldn't bother copper greasing if you are using loctite, the loctite is both a locking compound and an antiseizing measure. Use copious amounts of copper grease on any hot parts (exhaust studs etc) as normal grease will burn off. Always use thread lock on brake mounting bolts!

For normal engine bolts you don't really need loctite, a dab of copper grease and the bolts done up to the correct torque is plenty. Loctite is expensive so I only use it in the locations where the workshop manual suggests it is of some benefit. I use the blue loctite, have used it on loads of things of various temperature and it has held , the engine itself doesn't get THAT hot, the exhaust is the bit to avoid.

Don't use it on any plastic fairing/mudguard screws (not likely in your case but good general info). The vapours released during curing causes plastics to craze and crack arount the bolt holes if you use loctite.

As a general rule - red is permanent, blue is semi-permanent. anything you want to remove later don't use red on. Of course nowadays with so many grades it's better to look up the actual spec of the number on the bottle.

I have to use Loctite 243 on the threads of my bike's oil pressure sensor, so you wouldn't do too bad getting some 243 as it's heat and oil proof.
