Idler pulley's reverse threaded?
New owner of a used 2007 ES 350 (149,000mi)
I had a squeal from the engine bay I diagnosed as the Serpentine belt.
I replaced the Belt no problem.
While in there I checked the idle bearings, and can see that the idle pulley to the left of the tensioner needs replaced.
Bad pulley bearing (x)thing is I couldn't get the bolt off......
After putting it back together and now having just a slight squeal (especially when placing the car in gear) I realized the idle pulley may in fact be reverse threaded?
Can anyone confirm this for me? It's such a simple replacement I would like to save the $$ by doing myself.
**I also noted the idle bearing on the AC compressor also needs replaced, a bit tougher to access with a cross member in the way and hard to access bolts of the AC compressor (if I wanted to move it out of the way).
I think moving the Alternator out of the way would give me access to the AC compressor bolts on top side.
Probably have my mechanic tackle that one.

If you want to replace it you need a strong air gun. There's was no way to release mine without it.
