Can anyone tell me the part number for the tensioner pulley assembly I am having a hard time finding one.

Thanks

Thank you I was looking for the serpentine tensioner

I have a follow up question for this
I actually need to replace the tensioner pulley for the serpentine belt and have found one as low as $90 while the idparts is $160 (OEM is $350)
I'm guessing idparts is the way to go? also, how difficult is this to replace? I have already replaced the two static pulleys
Thanks for all the help.

Ken

Go with the one from idparts. The $90 one is prolly a junk crown brand and they have had too many failures.

Installation is pretty straight forward. You will need to remove the power steering pulley in order to take the the tensioner off
