i just found all my torque converter bolts loose and i just used red loctite and tightened them back up.what the time frame for 100% cure and dry time. i want them to be completely dry so they dont come loose. i might have started the car up prematurely the 1st time.

The friction & heat from torquing the bolt usually cures Red loctite almost immediately.
i put 1 bolt in hand tight with the loctite just to see after 2 hours if if would come out, yes it came right out and loctite was still wet and sticky. these are new bolts.

"hand tight" You must TQ it to stretch the bolt & produce the friction between the threads that the loctite uses to cure.....Yes it will not cure without the heat from friction.
technically, it has nothing to do with the heat and friction of tightening the bolt. Loctite is an anaerobic sealer. much like plain old superglue. you must remove any air for it to harden. a loose bolt doesen't do that. a tight bolt does. heat will soften the loctite after it's cured. how much heat depends on the grade of loctite used.

It ready to be used as soon as you torque the fastner. It doesn't have to dry.

I use assembly lube and a stretch gauge It's the only accurate way to tell for sure how much tension is actually in the bolt shank. Otherwise your torque reading could be overcoming friction in the threads and face of the nut and not clamping the cap! -Charles ps no Loctite either
