hey guys i have a silly question. I have a 1989 GMC k2500 with a 350 in it. I just pulled and rebuilt the motor, attaching the accessory bracket now. I purchased a new belt that matches the used one coming off and I am having trouble with my length. I have alternator top right, p/s below it a tensioner center above the water pump and the ac compressor top left. There is a bracket below the ac compressor that has me concerned, but I have all my parts accounted for..........or so I thought. Is there a pulley of some sort mounted below the compressor? I do not nave the A.I.R. belt which is longer, I replaced with the one coming off.

Most individuals that have a problem with serpentine belts, are due to incorrect routing. Are you missing the sticker, on the radiator shroud that indicates the correct routing?
