Installing serpentine belts on Pontiac gtp?

Answer 1

Both the accessory belt and supercharger belt are serpentine. The supercharger belt comes off first. The tensioner is under the coils and easy access. Use a 15mm socket and ratchet to release tension on the belt and remove the belt from one of the pulleys. Slowly and carefully release the pressure on the tensioner. I had to remove the radiator reservoir to get access to the accessory tensioner way in the back. Just remove two nuts and lift up. Plug the overflow hole. This accessory tensioner is left handed -turn it (counter clockwise) towards the firewall to release the tension. Using the same socket, relieve pressure on the belt and remove the belt from the alternator or take your pick of pulleys. Carefully thread the new accessory belt on all but the alternator. Use a flash light to verify that the belt is properly aligned on all pulleys. Use the rachet to move the tensioner back to the limit and carefully thread the new belt over the last pulley (alternator?). Let the tension off and use the flash light again to verify alignment. Do not get your finger between the belt and pulley! The tensioner being accidently release at such a time will cause damage to the flesh. Repeat with the supercharger belt.

(happened o me 2X and those supercharger belts are $100.) - Hardest to get seated correctly are the belts around the harmonic balancer. - for the S/C belt do all except the parts around the S/C pulley and tensioner. Do the pulley 2nd last and the tensioner last (easiest way to put it on). - Double check each belt pathway and seating 2 times before starting the car especially at the harmonic balancer level. - It helps if you do it in broad daylight or have a strong flashlight handy to see down low.
