2017 6.7 Powerstroke Serpentine Belt Routing and Diagram

Ensure proper belt routing and tension for the 2017 6.7 Powerstroke by closely following the belt diagram. The correct installation of the serpentine belt is vital for the smooth operation of your engine components. If the belt is misrouted or not properly tensioned, it can lead to system failures, overheating, or even complete engine shutdown.
The diagram is your primary reference for proper belt placement and routing. It shows how the serpentine belt loops around various components such as the alternator, power steering pump, air conditioning compressor, and tensioner. Check the diagram closely to ensure each section of the belt is routed in the correct direction, preventing any strain on the components and maintaining the engine’s efficiency.
Pay attention to belt tension as this plays a crucial role in the system’s performance. A loose belt can cause slippage, while a tight belt may stress the pulleys. Regular inspection of belt tension and condition is recommended to avoid issues such as squeaking noises or sudden belt failure.

The serpentine belt on the 2017 6.7 Powerstroke plays a crucial role in driving multiple engine components, including the alternator, power steering pump, and water pump. The belt routing is designed for efficiency, ensuring each accessory operates smoothly. If you’re replacing or inspecting the belt, it’s crucial to follow the correct path and tension specifications to avoid damage or premature wear.
Refer to the diagram to identify the belt path and ensure proper installation. The tensioner plays a key role in maintaining the correct tension across the belt. Be sure to check for any signs of wear or cracks on the belt, as this can lead to failure and engine damage. If the belt is worn, it’s important to replace it with a new one that matches the manufacturer’s specifications.
When installing the new serpentine belt, use a belt tensioner tool to adjust the tension. Improper tension can lead to excessive wear or slippage. Ensure all components, including the idler pulleys, are in good condition and properly aligned. Misalignment or faulty pulleys can cause the belt to wear unevenly.
Understanding the Serpentine Belt Routing on 2017 6.7 Powerstroke

The serpentine belt on the 2017 6.7 Powerstroke plays a critical role in driving multiple components such as the alternator, power steering pump, water pump, and air conditioning compressor. To ensure smooth operation and avoid damage, proper routing is crucial.
Here’s how to correctly route the serpentine belt on the 2017 6.7 Powerstroke:
- Start by identifying the main pulley on the crankshaft, which is the starting point for the belt route.
- The belt should pass over the large pulley on the alternator, followed by the water pump pulley.
- Continue routing the belt around the power steering pump pulley, making sure it aligns correctly to avoid slippage.
- Move the belt towards the air conditioning compressor, ensuring it passes under the tensioner pulley before returning to the crankshaft pulley.
Double-check the tensioner’s alignment and make sure the belt is seated properly in all grooves. Any misalignment can cause excessive wear or failure.
After routing the belt, rotate the tensioner pulley to ensure the belt is tight and secure. Make sure there is no slack or noise during engine operation.
Common Issues with the Serpentine Belt on 2017 6.7 Powerstroke
Wear and Tear is a primary concern for the serpentine belt. Over time, constant friction and heat exposure cause the belt to crack, fray, or even snap. Inspect the belt regularly for any visible damage, especially around the edges or grooves. If you notice significant wear, replace the belt to prevent unexpected failures.
Misalignment can occur due to a worn-out tensioner or pulley. Misalignment often leads to uneven wear on the belt, which may cause it to slip or fail. If you hear squealing noises or notice the belt moving erratically, check the tensioner and pulleys. Proper alignment is crucial for optimal belt performance.
Slipping happens when the serpentine belt loses tension. A loose or damaged tensioner spring can lead to a lack of tension, causing the belt to slip off or fail to grip pulleys properly. If you notice reduced performance in engine components like the alternator or air conditioning, inspect the tensioner and adjust the belt accordingly.
Contamination from oil, coolant, or other fluids can weaken the belt material. Leaks from nearby engine components may cause the belt to lose its grip and elasticity. If you spot fluid residue on the belt, clean the area and replace the belt if it appears damaged.
Improper Tension is another issue to consider. If the belt is too tight or too loose, it can cause premature wear or malfunctioning of driven components. Use a tension gauge to ensure proper tension, as excessive tightness can damage pulleys, while looseness can result in slippage.
Regular checks and maintenance of the serpentine belt can prevent most of these issues. Ensure your engine components are working correctly, and replace the belt at the first sign of trouble.
Step-by-Step Guide to Replacing the Serpentine Belt on 2017 6.7 Powerstroke

Disconnect the negative battery terminal to avoid any electrical hazards. Use a 15mm wrench to rotate the serpentine belt tensioner clockwise. This will release tension on the belt, allowing you to remove it from the pulleys.
Inspect the old belt for signs of damage such as fraying or cracks. If any are found, replace the belt with a new one. Ensure the new belt matches the size and specifications of the original.
Route the new serpentine belt over the pulleys according to the 2017 6.7 Powerstroke belt diagram. Carefully follow the belt path, making sure it runs over the alternator, power steering pump, AC compressor, and all other pulleys correctly.
Once the belt is properly routed, use the 15mm wrench to rotate the tensioner again and slide the belt over the final pulley. Release the tensioner slowly to apply tension to the belt.
Check the belt alignment and tension before reconnecting the battery. Start the engine and visually inspect the belt while the engine is running. Ensure the belt runs smoothly and is free from any unusual noise or slipping.
