I've got this real bad squeal in the engine area of my 05 Santa Fe 3.5L . I've pin pointed it to a idler pulley next to the Alt . Anyone know what the name of this part is ? .


Also i'm looking to replace the shifter light ...How to gain access to the area ? ...Book doesn't show that either

 

it is either the idler or the tensioner pulley.

 

The fixed black plastic pulley between the A/C and Alt on the iron mount is an idler..

The steel pulley with lip is used for adjustment of belt..

Parts fella can figure it out if you walk them to it..
