I can’t seem to find a straight answer to these questions, hopefully someone here knows about this stuff.
Does my 2007 3.5l V6 toyota sienna have an OAD style alternator pulley on it?
if not, what kind of pulley does it have on it?Is this a wear item that should be replaced if i am already doing the water pump and idler/tensioner replacement?
can the pulley be removed and replaced with the alternator in place?
why are there so many alternator replacement videos on youtube but very few if any videos on pulley replacement?
should i even be worrying about this at 115,000 miles?
thanks for any and all advice and help on this,

See if this helps:
i appreciate the reply.
Not so sure i want to take just that guy’s word for it though.
certainly gives me more to think about.still need to find out if my vehicle actually has one in the first place.
Simple enough.. does the alternator have a one way pulley?
Remove the drive belt and spin it in both directions.
If it locks up in the reverse direction you have a decoupler pulley.
Or simply look to see if there is a standard style nut attaching the pulley to the alternator or if there is a splined retainer screw.
