2022 Ram 1500 Serpentine Belt Routing, Length & Part Numbers

As an ASE-certified master technician, I know that keeping up with the serpentine belt maintenance on your 2022 Ram 1500 is critical to keeping your truck on the road. Whether you are hauling heavy loads or just commuting, a snapped belt will immediately disable your alternator, water pump, and A/C compressor.

Below is a comprehensive guide to the serpentine belt routing, part numbers, and replacement procedures for the 2022 Ram 1500. Note: Specifications below primarily focus on the highly popular 5.7L HEMI V8 (non-eTorque). If you have the 3.6L Pentastar V6, 3.0L EcoDiesel, or an eTorque-equipped engine, your part numbers and routing will vary.

Quick answer

Here are the essential specifications and part numbers for the standard 2022 Ram 1500 5.7L V8 serpentine belt system:

• Belt Length: 78.0 inches (Outside Circumference)
• Rib Count: 6-rib
• OEM Belt Part Number: Mopar 53032380AD
• Aftermarket Cross-References: Gates K060780, Dayco 5060780, Continental Elite 4060780
• Auto-Tensioner Part Number: Mopar 4593604AA (Aftermarket: Gates 38176)
• Idler Pulley Part Number: Mopar 53032119AA (Aftermarket: Gates 38042)

Belt routing

Before you even touch a wrench, take a clear photograph of your existing belt routing with your smartphone. It is incredibly easy to forget exactly how the belt weaves through the engine bay once it is removed.

Since we cannot render an image here, follow this text-based step-by-step description of the standard routing path. Start at the bottom of the engine and work your way around:

1. Start by looping the ribbed side of the belt around the bottom of the Crankshaft Pulley.
2. Route the belt up and around the outside of the A/C Compressor.
3. Bring the flat side of the belt over the smooth Idler Pulley.
4. Route the ribbed side of the belt around the Alternator at the top of the engine.
5. Pass the belt down around the Power Steering Pump (Note: Depending on your exact trim and whether your truck utilizes Electric Power Steering, this pulley may be absent or replaced by a secondary idler/routing path—always check your specific configuration).
6. Bring the flat back side of the belt under the smooth Water Pump pulley.
7. Finally, pull the remaining slack over the Automatic Tensioner Pulley, which will complete the loop back down to the crankshaft.

How to replace the serpentine belt

Replacing the serpentine belt on a 2022 Ram 1500 is a straightforward job that most DIYers can accomplish in the driveway in under 30 minutes.

Tools required:

• A dedicated serpentine belt tool or a long 3/8" drive breaker bar.
• A flashlight or headlamp.

Step-by-step replacement:

1. Locate the automatic belt tensioner on the front of the engine block.
2. Insert the 3/8" square drive of your breaker bar or serpentine belt tool directly into the square slot on the tensioner arm.
3. Rotate the tensioner to release the pressure on the belt.
4. While holding the tensioner open, slide the old belt off the easiest accessible pulley (usually the alternator or idler pulley).
5. Carefully release the tensioner and unthread the old belt from the remaining pulleys.
6. Thread the new belt according to the routing path described above, leaving the tensioner pulley for last.
7. Rotate the tensioner open once more, slip the belt over the tensioner pulley, and slowly release the tensioner arm so it applies pressure to the new belt.
8. Double-check every single pulley to ensure the ribs of the belt are perfectly seated in the grooves. An unseated belt will shred immediately upon startup.

Replacement interval

For the 2022 Ram 1500, the serpentine belt is made of highly durable EPDM rubber. The general recommendation is to inspect the belt every 30,000 miles and plan for replacement between 60,000 and 90,000 miles. Furthermore, it is highly recommended to replace the automatic tensioner and idler pulley at the same time you replace the belt, as the bearings in these components wear out at roughly the same rate.

Signs of a failing belt or tensioner

Do not wait for your belt to snap on the highway. Look out for these common warning signs:

• Squealing or Chirping: A high-pitched noise on startup or during acceleration usually indicates a stretched belt, a weak tensioner, or a failing pulley bearing.
• Visible Wear: Look for missing ribs, deep cracks, fraying edges, or chunking on the ribbed side of the belt. (Note: Modern EPDM belts do not crack as obviously as older neoprene belts; they wear deep into the grooves like a tire losing tread).
• Accessory Malfunctions: If your A/C stops blowing cold, your battery light flickers on, or your engine temperature starts creeping up, your belt may be slipping.
• Tensioner Bounce: With the engine running, observe the tensioner. If the arm is bouncing excessively, the internal spring is weak and it requires replacement.
