2017 Ram 1500 Serpentine Belt Routing Diagram and Installation Guide

Understanding the serpentine belt system on your 2017 Ram 1500 is key for maintaining its smooth operation. The serpentine belt drives multiple engine components, including the alternator, power steering pump, water pump, and air conditioning compressor. Without a properly functioning belt, these components can’t operate efficiently, leading to potential engine issues.
The diagram of the serpentine belt is a helpful guide for both installation and troubleshooting. When replacing the belt, it’s important to follow the correct routing to ensure proper tension and prevent damage to the engine components. The belt tensioner plays a key role in maintaining the right amount of pressure on the belt to avoid slippage.
To replace or inspect the serpentine belt, locate the belt routing diagram typically found on a sticker under the hood of your Ram 1500, or refer to the service manual. The diagram provides a visual guide for the belt’s path, helping you identify which pulleys and components it must pass over. Make sure to inspect the belt for signs of wear such as cracking, fraying, or glazing before replacing it.
Always use the correct replacement belt specified for the 2017 Ram 1500 model to avoid issues like excessive wear or poor performance. Replacing the serpentine belt in a timely manner prevents more costly repairs down the road and ensures optimal engine performance.
2017 Ram 1500 Serpentine Belt Diagram
To replace or inspect the serpentine belt on a 2017 Ram 1500, start by identifying the correct routing path. The diagram helps ensure the belt runs smoothly through all components, including the alternator, power steering pump, water pump, and air conditioning compressor.
Here’s how to follow the serpentine belt routing for your Ram 1500:
- The serpentine belt should first loop around the crankshaft pulley.
- From the crankshaft, it moves to the tensioner pulley, which applies necessary tension.
- Next, the belt travels to the alternator pulley, followed by the water pump pulley.
- The belt then loops over the air conditioning compressor pulley.
- It should pass through the power steering pump pulley before returning to the tensioner.
Double-check all routing to avoid misalignment. An incorrect installation can cause excessive wear or damage to the belt and other engine components. Use a belt diagram from the vehicle manual to ensure accuracy. If in doubt, replace the belt as per manufacturer guidelines for proper fit and function.
Step-by-Step Guide to Identifying Belt Routing on the 2017 Ram 1500

To identify the correct serpentine belt routing on a 2017 Ram 1500, locate the belt routing diagram typically found on the radiator support or the front of the engine bay. The diagram provides a visual guide, ensuring the belt wraps around the correct components.
The serpentine belt should loop around the alternator, power steering pump, air conditioning compressor, and water pump, among other components. It’s important to verify the tensioner pulley, which plays a key role in maintaining the proper belt tension. If your vehicle lacks a diagram, you can refer to the owner’s manual or consult the service manual for the specific routing details.
Start by turning the tensioner pulley counterclockwise using a ratchet or belt tool. This will release the tension and allow you to remove the old belt. Take note of the belt’s path and compare it with the diagram or manual before replacing it with the new one.
When installing the new serpentine belt, ensure it is seated correctly in all pulley grooves. Once the belt is in place, slowly release the tensioner pulley, allowing it to apply tension to the new belt. Check all pulleys to confirm they are aligned and the belt runs smoothly.
If in doubt, inspect the belt routing before reassembling any components, ensuring all connections are properly secured and the belt is correctly positioned to prevent any potential damage.
Troubleshooting Common Serpentine Belt Issues in the 2017 Ram 1500
If your 2017 Ram 1500’s serpentine belt is squealing, slipping, or showing signs of wear, it’s crucial to inspect it promptly. Start by checking for visible cracks or fraying. These are common signs of wear and may indicate that the belt is ready for replacement. If the belt appears shiny or glazed, this could be due to excessive heat or improper tension.
Check the belt tensioner. A malfunctioning tensioner can lead to belt slippage or excessive slack. If the belt is loose or the tensioner doesn’t move smoothly, it may need replacement. Similarly, listen for any unusual noises while the engine is running, as these can point to a problem with the belt or pulleys.
Inspect the pulleys for alignment and condition. Misaligned or worn pulleys can cause the belt to wear unevenly or slip. If you notice any pulleys wobbling or making noise, they should be replaced or aligned properly. A damaged pulley can cause the belt to wear prematurely and affect engine performance.
If your vehicle is overheating or showing signs of charging issues, the serpentine belt might not be turning the water pump or alternator correctly. In such cases, inspect the belt for any damage that could affect these components. Replacing the belt or addressing an issue with the pulleys can resolve these problems.
Lastly, if the serpentine belt is not installed according to the diagram, it can lead to misrouting and improper tension. Make sure the belt follows the correct path as outlined in the 2017 Ram 1500’s service manual. A misrouted belt can cause premature wear or even lead to complete failure.
How to Replace the Serpentine Belt on Your 2017 Ram 1500
First, gather the necessary tools: a ratchet, serpentine belt tool, and a new serpentine belt. Raise the front of the vehicle using a jack, then secure it with jack stands. This will give you the clearance needed to access the belt.
Locate the serpentine belt on the front of the engine. Use a diagram of your 2017 Ram 1500’s serpentine belt routing to help you identify the exact path it follows. The tensioner pulley, which keeps the belt tight, needs to be relieved before removing the old belt.
Position your serpentine belt tool on the tensioner pulley. Turn it counterclockwise to loosen the tension. Once you relieve the pressure, remove the belt from the pulleys and set it aside.
Now, inspect the pulleys and other components for wear or damage. If everything looks good, it’s time to install the new serpentine belt. Refer to your diagram and begin routing the belt around the pulleys, making sure it fits securely in each groove.
Once the belt is in place, use the serpentine belt tool to rotate the tensioner pulley back into position. Ensure the new belt is properly tensioned. Double-check the routing to confirm the belt is correctly aligned with all pulleys.
Finally, lower the vehicle, start the engine, and observe the belt’s operation. Listen for any unusual noises and ensure the belt runs smoothly without slipping or vibrating.
