    So, I picked up a 1999 1500 with a 4.8 automatic.
    I knew I was in for some work with the price of the truck and I am good with that. But I am having a hard time finding the A/C tensioner pulley listed on any of the normal websites I would buy parts (napa, kragen or pepboys). I did find one that looks like it might be used for both the drive and the a/c, but I am not 100% sure. I would rather have the part in hand when I start to repair.

    Any help would be great. Thanks!

    Nope. The sticker on the radiator shroud confirms that this truck does not use a single belt.

    I can see where the belt should be and when spinning the compressor it feels ok, when I spin the pulley, I can feel how bad the bearing is inside it. Also the free play on it.

    If anyone knows... Thanks.

    if you have not had luck there's two tensioner pulleys on mine one for the serpentine belt and then a separate belt just for the ac the tensioner fo that should be right next to the ac pump on the bottom left if you looking at the front of the vehicle. and they should be the same
