If there is no diagram pasted in the engine compartment, check your owner's manual...or else go to your local auto store warehouse or Chevy dealership...usually the parts counter person can print out the diagram specifically to your vehicle. Since you did not mention the engine specs- I'm going to generically how to install a serpentine belt.

1.) make a loop and slip the loop around the crank shaft pulley
2.) continue looping the belt around the water pump pulley
3.) ...around the A/C pulley
4.) ...and around the idler pulley
Skip the alternator pulley for now- you want to do that one last.
5.) Continue placing the belt around the power steering pump pulley
6.) and over the belt tensioner pulley
7.) Now move the belt tensioner position so that you can loop the belt over the alternator.
8.) Now double check to make sure that the belt is properly and securely fastened around each pulley's grooves. Don't start the motor until you are absolutely sure... and can visually verify that the new belt is installed properly. And don't have anyone (or pets) standing around the car or open engine compartment when you initially start the car just in case the belt breaks...serious injuries can occur!
I've attached a generic drawing it may or may not fit the description of your auto.

Go to Auto Zone and give them your make and model and ask for the serpentine belt diagram and leasve it in you glove compartment.

Need a diagram for the ECM A and ECM B pinouts on a 05 Dodge 2500 Cummins HO 5.9L.

Instructions

Things You'll Need
3/8-inch drive breaker bar
Metric sockets
Serpentine belt

1 Open the hood and inspect the flat surface on top of the plastic fan shroud for the belt routing diagram. Follow the diagram instructions to route the new belt.

2 Locate the serpentine belt self-adjusting tensioner on the front of the engine block. The tensioner has a pulley on the bottom of the tensioner arm, which the belt travels under. The tensioner can only be rotated from the bolt that secures the pulley to the tensioner arm.

3 Rotate the tensioner in a clockwise motion with a metric socket and the breaker bar to loosen the tension from the belt. Then, pull the belt off the top of the tensioner pulley. Release the tensioner pulley and pull the breaker bar off the pulley bolt.

4 Pull the belt out of the accessory pulleys. Then, slide the belt around each fan blade and out of the engine bay. Rotate each fan blade to the top side of the engine to get the belt around each fan blade.

5 Match both the new belt and the old belt together to make sure that the new belt is the correct size. Then, route the new belt around each fan blade and around the crankshaft pulley. The crankshaft pulley is the big pulley at the very bottom of the engine.

6 Follow the routing directions from the belt routing diagram to install the new belt around the other accessory pulleys. Once the belt has been routed around all of the pulleys, look over the belt and make sure that it is secure inside all of the pulleys.

7 Crank the 1998 Dodge Caravan and let the motor run for about 15 seconds. This will finish seating the ridges of the new belt into the grooves of each accessory pulley.

8 Shut the motor off and close the hood.

To install:
1. Position the fan on the drive clutch. Install the bolt and washer assemblies, then tighten to 12-17 ft. lbs. (16-24 Nm).

2. Position the fan drive clutch, fan assembly and fan shroud, then bolt the fan and clutch assembly to the water pump hub. Install and tighten the clutch retaining bolt and water pump assemblies evenly and alternately to 15-22 ft. lbs. (20-30 Nm) for the 3.8L engine or to 36-47 ft. lbs. (48-65 Nm) for the 5.0L engine.

3. Install the fan belt. Align the fan shroud and adjust for equal fan-to-shroud radiator clearance but maintaining a minimum of 0.38 inch clearance to the fan tip on 5.0L engines.

4. Install and tighten the shroud retaining screws. On 5.0L engines, snap the air deflector assembly to the sub-frame cross brace.

Hope helps (remember to rate and comment this).

Hi.

Here the belt routing for 2005 Dodge Sprinter 2005, whch was sold only with the 2.7 engine mounted:

PROCEDURE Removal & Installation


2.7L Engine

1. Loosen the tension adjust and remove the A/C compressor drive belt.
2. Attach a 3 / 8 inch drive ratchet to the automatic belt tensioner.
3. Rotate the belt tensioner counterclockwise to release the belt tension.
4. Remove the accessory drive belt, starting with the water pump pulley.



To install:

1. Position the accessory drive belt around every pulley except the water pump pulley.
2. Rotate the drive belt tensioner clockwise, install the accessory drive belt and release the tensioner.
3. Position the A/C Compressor drive belt over the crankshaft pulley and A/C compressor pulley.
4. Tighten the drive belt tensioner.
5. Ensure the belt is seated properly on all of the pulleys.

If no belt routing diagram on the hood or the radiator core support bracket, it's grooved part of the belt on grooved pulleys, slick pulleys on the slick side of the belt and 3/4 around the crankshaft pulley. Sounds strange but if you follow this rule of thumb, you can install any belt, Good luck, Gary

Here is what you need, hope it helps


# Serpentine Belt Ribs : 8
Belt Angle : 40 Deg
Outside Circumference (in) : 64.305"
Outside Circumference (mm) : 1633 mm
Top Width (in) : 1.087"

Have you located your local Cummins Dealer for this. It should be no issue for them to copy/email a diagram. Good luck...
