2016 Ram 1500 57 Engine Belt Diagram and Routing Guide for Maintenance
Check the 2016 Ram 1500 5.7 belt layout before attempting any repairs. The serpentine belt drives the alternator, water pump, power steering, and air conditioning, so correct routing prevents engine damage and ensures smooth operation.
Use the factory belt diagram for accurate reference. The belt wraps around the crankshaft pulley, tensioner, idler pulleys, and accessory pulleys in a specific sequence. Misalignment can lead to squealing noises, premature wear, or component failure.
Inspect pulleys and tensioners during replacement. Worn bearings or loose tensioners can reduce belt life. Apply moderate pressure to the tensioner to release the belt safely, then follow the diagram step by step for installation.
Keep a visual reference of the belt path. Taking a photo before removal helps avoid mistakes. Align the belt properly on each pulley, ensuring it sits in the grooves correctly, and rotate the engine manually after installation to confirm smooth movement.
2016 Ram 1500 5.7 Belt Diagram Guide
Follow the belt routing illustrated in the 2016 Ram 1500 5.7 diagram to prevent misalignment and premature wear. The serpentine belt starts at the crankshaft pulley, wraps around the alternator, tensioner, idler pulley, A/C compressor, and power steering pump, then returns to the crankshaft. Ensure the tensioner maintains proper tension and rotate it slowly to seat the belt correctly.
Inspect each pulley for signs of wear or wobble before installing the belt. Replace any worn components to avoid belt slippage or noise. Apply a light coating of belt dressing only if recommended by the manufacturer, as excessive lubrication can damage the belt.
Check alignment after installation by rotating the crankshaft two full turns. Verify the belt tracks smoothly over all pulleys without deviation. Listen for unusual noises, which may indicate misalignment or a failing pulley. Repeat the inspection after a short drive to confirm consistent performance.
Keep a spare belt in the vehicle for emergencies, especially during long trips. Use only OEM or high-quality replacement belts to maintain correct tension and durability. Follow the diagram closely, and the belt system will operate reliably, ensuring all engine accessories function properly.
Locating the Serpentine Belt on a 2016 Ram 1500 5.7
Open the hood and position yourself in front of the engine, slightly to the passenger side for a clearer view. The serpentine belt runs across multiple pulleys, connecting the alternator, power steering pump, water pump, and air conditioning compressor. Look for a long, continuous rubber belt with visible ribs on the inner side.
Identify the tensioner pulley, located near the top center of the engine. Use a wrench to rotate the tensioner clockwise, which will release tension on the belt and allow you to lift it off the pulleys. Follow the belt’s path from the crankshaft pulley at the bottom, tracing it clockwise to ensure it loops correctly over each accessory.
Check for the diagram sticker usually placed on the radiator support or the underside of the hood. Match the actual belt path with the diagram to verify proper routing. Confirm that the belt sits firmly in each pulley groove, and inspect for cracks or fraying along the ribs before reinstalling or replacing it.
Step-by-Step Belt Routing Diagram for 5.7 HEMI Engine
Follow this guide to route the serpentine belt correctly on the 2016 Ram 1500 5.7 HEMI engine. Ensure the engine is off and cool before beginning. Use a belt routing diagram for reference to avoid misalignment and damage.
- Locate the crankshaft pulley at the bottom center of the engine. This pulley serves as the starting point for the belt.
- Route the belt clockwise around the water pump pulley, keeping it snug and aligned with the pulley grooves.
- Continue the belt over the alternator pulley, ensuring it sits evenly within the grooves to prevent slipping.
- Guide the belt around the tensioner pulley. Use a wrench to rotate the tensioner and slide the belt into place smoothly.
- Loop the belt over the power steering pump pulley, maintaining proper tension.
- Pass the belt over the idler pulleys as indicated in the diagram, confirming each segment aligns with the pulley grooves.
- Finish the routing by bringing the belt back to the crankshaft pulley, double-checking that all pulleys are correctly engaged.
After installation, rotate the crankshaft manually two full turns to confirm smooth belt movement. Inspect all pulleys for alignment and tension before starting the engine. Replace the belt immediately if any wear or misalignment is detected.
Keep a printed diagram nearby while performing maintenance to ensure accuracy. Proper routing prevents premature wear, maintains engine performance, and avoids costly repairs.
Replacing and Tensioning the 2016 Ram 1500 Serpentine Belt
Loosen the serpentine belt by rotating the tensioner clockwise using a 3/8-inch ratchet or breaker bar. Slide the old belt off the pulleys, paying attention to the routing. Compare the new belt with the old one to confirm length and rib alignment before installation.
Follow the belt diagram to loop the new belt around the pulleys. Start with the crankshaft pulley, then route it over the alternator, idler, A/C compressor, and power steering pulleys. Leave the tensioner for last to allow easier placement.
Apply steady pressure to the tensioner and slide the belt into its final groove. Release the tensioner slowly, ensuring the belt seats properly on all pulleys. Inspect each pulley to confirm alignment and prevent mis-tracking.
Turn the engine manually using a wrench on the crankshaft pulley for two complete rotations. This helps the belt settle into place and ensures smooth movement without skipping or rubbing.
| Pulley | Position on Belt |
|---|---|
| Crankshaft | Drives all accessories |
| Alternator | Top right |
| Power Steering | Middle right |
| A/C Compressor | Bottom left |
| Idler Pulley | Top left |
| Tensioner | Adjusts belt tension |
Check belt tension by pressing on the longest span. It should deflect about half an inch under moderate pressure. Tighten or adjust the tensioner if necessary to maintain proper tension and prevent slippage.
After installation, start the engine and observe the belt in operation. Look for wobbling, squealing, or misalignment. Recheck tension after the first few miles of driving to confirm stability and longevity.
