2017 Ram 1500 5.7 Belt Diagram and Routing Instructions

To keep your 2017 Ram 1500 running smoothly, it’s critical to understand the layout of the serpentine belt. The 5.7L engine features a specific belt routing that powers the alternator, air conditioning compressor, power steering pump, and other vital components. If you’re experiencing issues with your belt or simply performing maintenance, knowing the exact diagram will save you time and effort.
The serpentine belt on the 2017 Ram 1500 5.7L follows a precise path to ensure all components are driven efficiently. Start by identifying the belt tensioner, which allows for adjustments as the belt stretches over time. From there, the belt travels around the alternator, idler pulleys, and other accessories, making a full loop before returning to the tensioner. The diagram will provide the exact sequence and pulley arrangement.
Replacing the serpentine belt or performing inspections requires careful attention to the belt’s condition and proper alignment. Ensure the tensioner is functioning properly before installation, as a malfunctioning tensioner can cause misalignment and premature wear. Keep this diagram handy as a reference to avoid any confusion during maintenance.

The belt diagram for a 2017 Ram 1500 5.7 HEMI is crucial for proper installation and maintenance of the serpentine belt system. If you’re replacing the belt, refer to this guide to ensure it’s installed correctly. A mistake can cause engine overheating, power loss, or damage to accessories like the alternator or A/C compressor.
The serpentine belt in the 2017 Ram 1500 5.7 runs various components: the alternator, power steering pump, water pump, and air conditioning compressor. The diagram for this vehicle features a single serpentine belt that loops around the pulleys of these parts, ensuring smooth operation of the engine’s accessory systems.
When installing the belt, start by ensuring the tensioner is loosened, then carefully route the belt around the pulleys according to the diagram. The tensioner will automatically apply the necessary tension once the belt is in place. Make sure to inspect the pulleys and tensioner for any signs of wear or damage before installation. Replacing the belt every 60,000 to 100,000 miles is recommended, but if you notice any cracks or signs of damage earlier, replace it immediately to avoid any issues.
To ensure a proper fit, it’s important to get the correct replacement belt for the 2017 Ram 1500 5.7. Check your vehicle’s manual for the specific part number for the serpentine belt. If you’re unsure, visiting a certified mechanic or auto parts store can help confirm the correct size.
How to Identify the Components of the 2017 Ram 1500 5.7 Belt System
First, locate the serpentine belt and pulley system. The serpentine belt runs across various components, providing power to multiple accessories, including the alternator, power steering pump, and air conditioning compressor. Examine the belt’s routing path, which is typically illustrated on a decal found near the radiator or on the front of the engine bay. This diagram is your roadmap for understanding how the belt connects each component.
Next, focus on the main pulleys. The crankshaft pulley, located at the engine’s bottom, serves as the primary driver for the serpentine belt. From there, the belt runs across idler pulleys, tensioner pulleys, and accessory pulleys. The idler pulleys guide the belt and maintain its tension, while the tensioner pulley automatically adjusts the belt’s tightness, ensuring smooth operation. Identifying these components requires a careful visual inspection, looking for the various pulleys that the belt loops around.
The alternator is another critical part of the system. Its pulley is positioned to receive power from the belt, converting mechanical energy into electrical energy. Check its location to confirm the belt’s connection. The power steering pump and A/C compressor also have pulleys that drive their respective functions. Both should be easy to spot, usually toward the front of the engine compartment, directly in line with the belt.
If the belt appears loose or misaligned, it may indicate a problem with one of these components. A worn-out tensioner or damaged pulley can cause improper belt tension, leading to slippage or even breakage. Always check for signs of wear, such as cracks or fraying, to ensure the belt and components are functioning properly.
For clarity, refer to the manufacturer’s guide for specific belt routing instructions. This will help you identify each component and their respective placement in the system more accurately.
Step-by-Step Guide to Replacing the Serpentine Belt on the 2017 Ram 1500 5.7

To replace the serpentine belt on your 2017 Ram 1500 5.7, follow these steps for a smooth process:
- Gather Tools and Materials: You’ll need a new serpentine belt, a 3/8″ drive ratchet, a serpentine belt tool, and possibly a socket extension.
- Locate the Belt Routing Diagram: Find the belt routing diagram, usually located on the front radiator support or under the hood. This will guide the reinstallation of the new belt.
- Release Tension on the Belt: Using the serpentine belt tool, position it on the tensioner pulley. Rotate it counterclockwise to relieve tension and remove the old belt. Be cautious, as the tensioner is under spring load.
- Remove the Old Belt: Once the tension is released, slip the old belt off the pulleys. Take note of the belt’s path, as you’ll need to follow the diagram for the new one.
- Install the New Belt: Position the new serpentine belt according to the diagram. Begin by routing it around the pulleys, ensuring it fits snugly. Pay close attention to how the belt sits in the grooves of each pulley.
- Reapply Tension: Rotate the tensioner pulley again with the serpentine belt tool to create tension on the new belt. Ensure the belt is properly aligned and seated on all pulleys.
- Double-Check Alignment: Inspect the belt’s alignment on each pulley to confirm it is correctly positioned. If any misalignment is found, adjust the belt as needed.
- Test the Installation: Start the engine and observe the belt in operation. Listen for any unusual noises or irregularities. If everything runs smoothly, the replacement is complete.
Regular maintenance of the serpentine belt is essential for ensuring the longevity and reliability of your vehicle’s engine components.
Common Issues and Troubleshooting the 2017 Ram 1500 5.7 Belt System

If you notice unusual noises or engine performance issues, the belt system on your 2017 Ram 1500 5.7 could be the culprit. One common problem is belt wear, which leads to slipping and squealing sounds. Over time, the serpentine belt can degrade due to exposure to heat, dirt, and oil. Replacing a worn or cracked belt can often solve this issue.
A misaligned or damaged pulley may also cause the belt to wear unevenly. Inspect all pulleys for damage and make sure they rotate freely. If a pulley is damaged or malfunctioning, it should be replaced to prevent further damage to the belt and other components.
Belt tension is another critical factor. Too much tension can cause premature wear, while too little tension can lead to slippage. Use a belt tension gauge to ensure the proper tightness. If the tensioner appears faulty or worn, replace it immediately to maintain proper belt tension.
Another issue is the water pump or alternator seizing up, which can cause the belt to snap. Check for any unusual resistance when turning these components by hand. If either part feels stiff or hard to turn, it may need to be replaced, as a seized component can prevent the belt from moving properly.
Finally, if the belt is making a high-pitched squeal, it may be due to oil or coolant contamination. Clean the belt and pulleys thoroughly and replace any affected components. Keeping the belt system clean and properly maintained will extend its lifespan and prevent most common issues.
