Loctite on timing belt idler pulley bolt?

I'm putting my 3.4 back together and I didn't see anywhere in the FSM about thread lock (even removable) for any of the fasteners?

 

It never says that but its on you if you want to or not.

 

Had mine done by a reputable mechanic and a month later it came loose. They used lock tite on round 2.

 

If you do use loctite, use blue. But it's not in the manual because it's not necessary. Lots of bolts don't have loctite because standard torquing is sufficient.

 

And they did not use a torque wrench on round 1.

 

They said they did....it took a month to come loose. Might be one of those thing you wanna retorque after a few miles.
