What threadloc should I use on the flexplate bolts, convertor nuts and bellhousing bolts?

Thanks!

 

I've never used any and never had a problem.
Maybe I'm wrong.
Might not be a bad idea on the flex plate and T.C. to flex plate bolts though.
Use the blue stuff 242.
I definitely wouldn't put any on the bell housing bolts. If you ever have to unbolt them again you'll have to back them out all of the way under power, no turning them with your fingers to speed things up.

 

You really only need to put threadloc on the flex plate bolts. Use the blue stuff it works really well.

 

Actually you need to use a thread sealant.
Those bolt holes go through the crankshaft into the crankcase.

All manuals I have ever read specify thread sealant on flywheel bolts.

 

Thanks guys!!! Looks like some sealant and a little blue.
