2011 Ram 5.7 Belt Diagram and Engine Serpentine Belt Routing Guide

To maintain your 2011 Ram 5.7 HEMI, it’s crucial to have the correct belt diagram on hand. This diagram shows how the serpentine belt routes through various components like the alternator, power steering pump, and AC compressor. Accurate routing prevents belt slippage and damage to engine parts.
Locate the tensioner and follow the diagram to ensure proper installation. The tensioner’s position is vital for keeping the belt tight enough to avoid excessive wear. The belt should smoothly run through all pulleys without twisting or bending sharply.
If you’re replacing the serpentine belt, double-check the part number to match the belt length and size. A wrong fit can lead to misalignment, causing squealing or even the belt coming off. Follow the manufacturer’s specifications carefully for a hassle-free replacement.
2011 RAM 5.7 Belt Diagram
The 2011 RAM 5.7 belt diagram provides a clear guide to correctly routing the serpentine belt. Ensure that the belt follows the exact path shown in the diagram to avoid damage to the components it drives. The serpentine belt on this vehicle drives several crucial systems such as the alternator, power steering pump, and air conditioning compressor. Incorrect routing can lead to excessive wear or failure of these systems.
Start by confirming the belt size: a 2011 RAM 5.7 uses a 7-rib serpentine belt. The tensioner should always be checked for proper function, as a worn-out tensioner can cause the belt to slip or squeal. The diagram usually places the tensioner in a convenient location, making it easy to relieve pressure and install the belt.
It’s important to inspect the belt for signs of wear like cracks, fraying, or glazing. Replace the belt if any of these issues are present. During installation, make sure the belt is aligned properly on all pulleys and that the ribs are seated evenly. Tightening the tensioner correctly is necessary to prevent slipping.
If you’re unsure of the exact routing, refer to the vehicle’s service manual or consult with a mechanic. Maintaining the correct belt tension and routing is key for reliable engine performance.
Step-by-Step Guide to Locating the 2011 RAM 5.7 Serpentine Belt Routing

To locate the serpentine belt routing for the 2011 RAM 5.7, begin by identifying the components in the engine bay. You’ll find the belt on the front of the engine, wrapping around the various pulleys, including the alternator, power steering pump, water pump, and A/C compressor.
Look for the belt tensioner, which is typically located near the top of the engine, and often marked with a pulley icon or the word “tensioner.” It is a spring-loaded pulley that keeps the belt tight. This is a key part of the system that maintains proper tension for optimal operation.
Next, check the diagram located on the engine bay or inside the hood. RAM includes a label showing the belt routing, which provides a visual map of how the serpentine belt should be positioned around the pulleys. This is your reference for correct placement.
If the diagram is missing or unreadable, you can reference the owner’s manual or use a service manual specific to your RAM 5.7 model. These manuals contain detailed belt routing diagrams that will guide you in the correct alignment.
Once you have the belt routing diagram, follow the sequence of pulleys listed. Ensure that the belt loops correctly over each one, with the smooth side of the belt touching the pulleys that don’t have ridges and the ribbed side of the belt touching those that do.
Make sure the belt is aligned properly with the pulleys. Misalignment can lead to wear and possible failure. If the belt appears worn, cracked, or loose, it’s a good time to replace it to avoid further issues.
Troubleshooting Common Belt Issues in the 2011 RAM 5.7

If your 2011 RAM 5.7 is showing signs of belt trouble, follow these steps to diagnose and fix common problems effectively:
- Squealing or Chirping Noises: A noisy belt often indicates wear or misalignment. Inspect the belt for visible cracks or fraying. If the noise persists, check the pulleys for any signs of misalignment or corrosion. Tighten or replace the affected parts as needed.
- Slipping Belt: If the belt is slipping, it may be too loose. Check the tensioner to ensure it is functioning properly. A worn-out tensioner will fail to keep the belt tight enough. Replace it if necessary and adjust the belt tension to factory specifications.
- Cracked or Worn Belt: Over time, belts naturally wear out. Inspect the belt for any cracks, fraying, or glazing. If you find these issues, replace the belt immediately to avoid more serious damage to your engine components.
- Belt Off-Pulley: A belt that comes off the pulleys could be due to improper installation, a faulty pulley, or a broken tensioner. Carefully re-align the belt and inspect the pulleys for damage. Replace any faulty pulleys or tensioners before reinstalling the belt.
- Overheating or Smell of Burnt Rubber: An overheating belt may result from excessive friction, which can be caused by a misaligned pulley or insufficient tension. Check for debris, foreign objects, or pulley damage. Ensure the pulleys rotate freely and the belt is properly aligned.
Regular maintenance is key to preventing these issues. Keep an eye on your belt’s condition and address minor problems early to avoid costly repairs later.
How to Replace the Serpentine Belt on a 2011 RAM 5.7
To replace the serpentine belt on your 2011 RAM 5.7, you’ll need a 15mm socket wrench, a serpentine belt tool, and a replacement belt. Start by locating the tensioner pulley and using the wrench to relieve tension on the belt. Turn the tensioner clockwise and remove the old belt from the pulleys.
Once the belt is off, compare it with the new one to ensure proper sizing and routing. Check the diagram for your specific engine model, which is usually located on the fan shroud or under the hood. The belt must follow the exact path outlined in the diagram.
Install the new belt by following the routing sequence. Begin by placing the belt on the pulleys, making sure it fits snugly around each component. After you’ve placed the belt in position, use the serpentine belt tool to release the tensioner and allow the belt to settle in place.
Double-check the alignment of the belt on all pulleys. If everything looks good, start the engine and observe the belt’s movement to ensure it’s running smoothly. Listen for any unusual noises or misalignments. If the belt doesn’t sit properly or there are noises, repeat the process to correct the issue.
Always replace the serpentine belt at regular intervals or if you notice any signs of wear, such as cracks or fraying. Regular maintenance will help avoid potential damage to your engine components.
