Use thread locker on flywheel bolts???
I just put the flywheel back on my '71 350ci. I torqued the bolts to 60 lbs as the Haynes manual suggested, using a cross pattern.
I'm now wondering if that's good enough, or should I have used some high-strength thread locker for extra measure? I've still got the trans out, but the bellhousing is already in place.
I've got visions of the flywheel coming loose and cutting my legs off!!!
Are you guys doing anything extra when re-installing flywheels?
Thanks...

You don't need thread-locker. They weren't installed that way at the factory. But I always put locker on the flywheel and clutch bolts since it's not something I want to have to think about. Yes, if you properly torque the bolts, they'll stretch properly and be secure...probably forever. But a couple drops of thread-locker makes me sleep better.

While it is not required and the bolts come with lock washers I always use loctite the same as gerry72

I have to admit I've gotten into the habit of using thread locker whenever I can. With the exception of head bolts and water passage bolts I use it on everything. Had a bad experience with a caliper coming loose on my 78 when I first got it back in 95. Really chewed up my wheel and scared the you know what out of me.

My ARP flywheel bolts came without lock (star) washers and had a note saying not to use lock washers.
Carguy4sure - whose bolt set did you buy that came with washers?

sorry, ive yet to see any style lock washer on a flywheel bolt. as a matter of fact, we just put a center force in my buds 97 cobra and guess what? no washers. how would you get correct torque set on this kinda important fastener with a crushable star washer under it? id guess if youve found washers, they have been installed by others over the years. just my .02

There's no reason you shouldn't be able to break it down with heat but I still play it and safe use blue on small fasteners. Don't need to be breaking things off.
Does anybody have experience with the glue-stick type Locktite? I have some but haven't really used it yet. I hate the liquid type dripping off everywhere...
