Understanding the 2016 Ram Promaster 3.6 Engine Belt System

The 2016 Ram Promaster 3.6 engine utilizes a serpentine belt system to drive various accessories, including the alternator, power steering pump, and air conditioning compressor. Regular maintenance of this system, including replacing the belt and pulleys, is crucial for optimal engine performance and longevity. In this article, we will provide a comprehensive guide on understanding and servicing the 2016 Ram Promaster 3.6 belt system.

Replacing the Serpentine Belt and Pulleys

Materials Required

• New serpentine belt (part number: 68024254AA)
• Replacement idler pulley (part number: 53030750AA)
• Replacement tensioner pulley (part number: 53030749AA)
• Socket wrench set
• 18mm socket
• 15mm socket
• Breaker bar
• Torque wrench

Step-by-Step Procedure

1. Safety First: Disconnect the negative terminal of the battery to prevent electrical shock.
2. Remove Air Box: Unclip the hose clamp and remove the air box to access the belt and pulleys.
3. Release Tensioner: Use the 18mm socket to rotate the tensioner counterclockwise and release the belt tension.
4. Remove Belt: Slide the belt off the pulleys.
5. Replace Idler Pulley: Remove the 15mm bolt holding the idler pulley, install the new pulley, and tighten the bolt to 65 ft-lbs.
6. Replace Tensioner Pulley: Remove the 15mm bolt holding the tensioner pulley, install the new pulley, and tighten the bolt to 89 ft-lbs.
7. Install Belt: Route the new belt around the pulleys, starting from the crankshaft pulley.
8. Tension Belt: Use the breaker bar to rotate the tensioner clockwise and apply tension to the belt.
9. Check Alignment: Ensure the belt is properly aligned on all pulleys.
10. Tighten Tensioner: Use the torque wrench to tighten the tensioner bolt to 53 ft-lbs.

Troubleshooting and Additional Tips

• “Hack” for Alignment: To simplify the alignment process, consider using a laser pointer pen as a guide. Point the laser at the pulleys and adjust the tensioner until the laser hits the center of each pulley.
• Replace Pulley Simultaneously: It is recommended to replace both the idler and tensioner pulleys simultaneously for increased longevity.
• Check Water Pump: While servicing the belt system, inspect the water pump for any signs of leakage or damage.
• Use High-Quality Parts: To ensure durability and reliability, use high-quality replacement parts.
• Consult a Mechanic: If you are not comfortable performing this task yourself, do not hesitate to consult an experienced mechanic for assistance.
