But 140 is ok for m14 threads

Or just don't put any antiseize on your lug nuts which you should not do at all anyway. A very light coating on the mating surfaces is allowable but never on the threads per GM.

Don't use antisieze. There is no need for it.

Absolutely just saying ,lots of shops will slap some on without you knowing so just more of an FYI, than a requirement.

As long as there is no antiseize on the base of the lugnut when torqueing and only a light coat on the threads, there are no ill effects.

I'd follow GMs spec if possible but in no way the end of the world if a shop used anti seize. Hense why I mentioned the reduced spec if it's used.

Is the factory service manual available to download or do you have access for your job?

I was just thinking today I would like to know the tq spec but didn't really look around, thanks for the info all.
