All Pulley's Left-Hand Thread?

I am replacing all the pulleys in my 96. I believe the tensioner is a LEFT-HAND thread (#50 Torx), correct? Are any of the other pulleys left-hand thread? Don't want to snap anything off.
Thanks - Bill

OK, now I'm confused. There's a big orange sticker on my fan shroud that say's "Caution, Fan Right Hand Thread". My manual also say's the fan is a right hand thread. I was also reading another thread that said the Torx bit on the tensioner was left hand.

Your right, I'm sorry was thinking of another vehicle. That's what happens when you work to many different thing's. On the other hand I am sure that both my idler and tensioner pulley are right hand thread but that's not saying that something didn't change at one point.

Tensioner pulley is the only left-hand threaded pulley. The rest are all right-hand threaded (and fan clutch too). Cheers!

Stupid question. It is the TORX on the tensioner that's left hand or just the bolt that holds the actual pulley wheel to the tensioner?
Thanks again - Bill

Not a stupid question at all! The torx that holds the tensioner assembly to the engine is right-hand threaded. The tensioner pulley bolt is left-hand threaded. Cheers!

Whew! Thanks. They're already tight, just didn't want to tighten them more.
