loctite on flywheel to torque converter bolts?

[CoJames]

I've got a 2001 L300 with the 3.0l V6 with automatic trans. I'm in the process of replacing the engine, and I've been using a Haynes manual as a guide, especially on torque specs.

The three torque converter to flywheel bolts - the manual says to torque to 48 lb-ft. But it says nothing about using loctite / thread locker on them. These bolts seem pretty important. Should I use loctite on them? If so, red (perm) or blue (removable)? Is it critical? Will it make them too hard to get out in the future?

TIA.

If you're not expecting to regularly replace this engine, it won't really matter if you use Loctite or not. To be safe, use blue only. Red will be permanent and extremely difficult to break loose (unless lots of heat is used ). Blue Loctite is the color of choice for future removal as it won't allow vibration to loosen these bolts. If you really want to get technical, green Loctite is for oily/greasy nuts/bolts that aren't cleaned.

And if you didn't know that threads are supposed to be clean before applying Loctite, you didn't hear it from me.....................................

Thanks! I definitely don't plan to replace this engine very often. ;-)
