2001 Other GMC Models Serpentine Belt Routing for C6500 Truc

2001 Other GMC Models V8 Two Wheel Drive Automatic 75000 miles

I lost the belt off of my Furniture moving truck, the alternator froze up and broke the belt on the highway somewhere and there is no belt routing diagram anywhere under the hood. It has 9 routing points on the 502 big block Chevrolet engine. It has the Crank, Water Pump, Fan, P/S pump, A/C, Alternator, Tentioner, and 2 Idlers. The Fan is not on the Water Pump it is a shaft mounted Idler (Large Pulley), the water pump has only a pulley on it. It has a Sanden Compressor for the A/C with an Idler to the side and under it. The tentioner is next to the water pump and the alternator is under the A/C. The Power steering is on the top and Right side of the motor as you are standing in front of the truck with an idler under it. If you can help, please email me a diagram of this belt arrangement as I have tried 15 different belts varying in size from 101 inches to 124 inches with no luck. The belt has 7 ribs on all pulleys, All pulleys are ribbed with the exception of the water pump, 2 idlers, and the tentioner. The other 5 are all ribbed like the belt. I have no idea of the water pump rotation so I don't want to burn up the motor by running the belt around the water pump in the wrong direction.
