Serpentine Belt Pulley Bolt - Loctite Needed?
In replacing the thermostat, I removed the upper pulley on the serpentine belt. I neglected to put Loctite on the threads. Do y'all know if that is critical?

I can only say that I have never put loctite on any pulley on any engine. In fact, I often put anti-seize on them. I'm pretty sure the way the belt runs that it's always trying to tighten the pulley? Thinking about that, though, I'm not sure if that applies to all pulleys.
