2016 Ram ProMaster City 2.4 Serpentine Belt Diagram

The serpentine belt on your 2016 Ram ProMaster City 2.4 engine is responsible for driving multiple accessories such as the alternator, power steering pump, and air conditioning compressor. It’s crucial to maintain the correct belt routing to ensure optimal engine performance.
The serpentine belt routing for this model follows a specific path. Begin by routing the belt around the crankshaft pulley, ensuring it moves in a counter-clockwise direction. From there, it should move over the A/C compressor pulley, followed by the alternator. Ensure the belt is aligned with the tensioner pulley next, before wrapping around the power steering pump. Finally, confirm the belt is properly seated on the idler pulley before it finishes back on the crankshaft pulley.
Make sure the belt is routed in a manner that it runs smoothly through all pulleys without slipping or twisting. Any misalignment can cause premature wear, excessive noise, or even failure of engine components. It’s recommended to inspect the belt at regular intervals for signs of cracking, fraying, or glazing to prevent unexpected breakdowns.
Refer to the vehicle’s service manual for a precise diagram to guide you through the process and avoid any potential installation issues. Proper tension adjustment is critical, so be sure to check that the belt tensioner is functioning correctly.
How to Identify the Serpentine Belt Routing for 2016 Ram ProMaster City 2.4
The serpentine belt routing for the 2016 Ram ProMaster City 2.4 can be easily identified by following the diagram located on the engine’s radiator support or the hood’s underside. This visual guide will help you ensure the belt is properly routed for optimal performance. If the diagram is missing or hard to read, refer to the vehicle’s service manual for specific routing instructions.
The belt typically starts at the crankshaft pulley and moves in a specific path through several components. The path generally includes the alternator, power steering pump, water pump, and air conditioning compressor. The tensioner pulley plays a key role in maintaining the correct tension along the belt’s route. Make sure the belt aligns properly with each pulley to avoid slippage or damage.
If you need to replace or inspect the serpentine belt, use a diagram as your guide to ensure proper reinstallation. When routing, check for any worn or damaged components that could affect belt performance. A good way to identify incorrect routing is to ensure there are no twists or slack in the belt’s path. Always double-check the tensioner to ensure it maintains the right amount of pressure on the belt for efficient operation.
For accurate identification of the belt routing, it’s always best to consult the vehicle’s maintenance guide, or inspect the engine compartment for the factory routing diagram. If no diagram is found, consider using a third-party repair manual for detailed illustrations of the belt’s path on the 2.4L engine.
Step-by-Step Guide to Replacing the Serpentine Belt on a 2016 Ram ProMaster City 2.4

To replace the serpentine belt on your 2016 Ram ProMaster City 2.4, follow these steps:
- Gather necessary tools: You’ll need a socket wrench, a serpentine belt tool or a 3/8-inch drive ratchet, and a new serpentine belt. Check your vehicle’s manual for the specific belt size and tension specifications.
- Locate the serpentine belt: Open the hood and find the serpentine belt at the front of the engine. The belt runs through various pulleys, including the alternator, water pump, and power steering pump.
- Release the tension on the belt: Use the serpentine belt tool or ratchet to move the tensioner pulley. The tensioner is located near the center of the belt system. Pull it in the direction that loosens the belt tension, and carefully remove the belt from the pulleys.
- Remove the old serpentine belt: Once the tension is released, carefully remove the belt from all pulleys. Note the routing of the belt as you remove it–this is important for installing the new one.
- Install the new serpentine belt: Refer to the belt routing diagram, which should be on the engine bay or in the owner’s manual. Carefully route the new belt around the pulleys, ensuring it sits properly in each groove.
- Reapply tension: Once the belt is in place, use the serpentine belt tool or ratchet to move the tensioner pulley back into position, applying tension to the belt. Ensure the belt is snug but not overly tight.
- Inspect the installation: Double-check the belt’s position on all pulleys. Make sure it’s properly aligned and seated correctly.
- Test the belt: Start the engine and observe the serpentine belt in motion. Listen for any unusual sounds or movements, which might indicate improper installation or a misaligned pulley.
Once everything is confirmed to be in order, close the hood and dispose of the old belt properly. You’ve successfully replaced the serpentine belt on your 2016 Ram ProMaster City 2.4!
Troubleshooting Common Serpentine Belt Issues in the 2016 Ram ProMaster City 2.4

Inspect the serpentine belt regularly for visible wear such as cracks, fraying, or glazing. A damaged belt can lead to engine overheating or power steering failure, among other issues. If the belt shows signs of damage, replace it immediately.
If you hear squeaking or squealing noises from the engine compartment, it’s often a sign of belt slippage. Check the tension of the serpentine belt. A loose belt can slip, causing noise and improper functioning of accessories like the alternator or air conditioning. Adjust the belt tension to the manufacturer’s recommended specs, or replace the tensioner if it’s worn out.
Another issue to look out for is the belt jumping off the pulleys. This usually happens when the pulleys or belt are misaligned. Inspect all pulleys for damage or misalignment, and replace any worn components. It’s also a good idea to check for any oil or coolant leaks that may have compromised the belt’s grip on the pulleys.
If you notice that electrical systems or other accessories are malfunctioning, it may be due to the serpentine belt not driving the alternator effectively. In this case, a new belt or adjustment is often the solution. Always ensure that the belt is installed correctly and aligned with all pulleys to prevent these issues.
Finally, if the engine is overheating, check the belt for proper operation of the water pump. If the belt isn’t working as it should, the water pump can fail, causing the engine to overheat. This can quickly escalate into more serious damage, so it’s crucial to address the issue before it gets worse.
