Belt Routing

Note: This description is for common engine configurations. Always verify the routing diagram on your vehicle's engine bay or in your owner's manual. It is highly recommended to take a clear photograph of your existing belt routing before removal to ensure correct installation.

Here's a general serpentine belt routing path for many 2024 Ford F-350 Super Duty engines, starting from the crankshaft pulley:

1. From the crankshaft pulley, the belt typically travels upwards to the A/C compressor pulley.
2. From the A/C compressor, it then often routes to an idler pulley (or a series of idler pulleys depending on the engine).
3. From the idler pulley, the belt usually goes to the alternator pulley.
4. After the alternator, it may wrap around the power steering pump pulley.
5. Next, the belt often routes to the water pump pulley.
6. Finally, the belt connects to the automatic tensioner pulley, which maintains proper belt tension throughout the system.

Engine Variation Note: The 2024 Ford F-350 Super Duty offers several powerful engine options, including the 6.8L V8, 7.3L V8 "Godzilla," and the 6.7L Power Stroke V8 diesel. Each of these engines will have a unique serpentine belt routing, specific belt length, and corresponding part numbers for the belt, tensioner, and idler pulleys. Always consult your vehicle's owner's manual or a reliable parts catalog specific to your engine for accurate information.

How to Replace the Serpentine Belt

Replacing the serpentine belt on your 2024 Ford F-350 Super Duty can be a DIY task for those comfortable with basic automotive repairs. You will need a serpentine belt tool or a 3/8-inch breaker bar that fits into the square drive opening of the automatic tensioner.

1. Gather Your Tools and Parts: Ensure you have the correct replacement belt, a serpentine belt tool or breaker bar, and possibly a socket set if you need to remove any other components for access.
2. Locate the Belt Routing Diagram: As mentioned, take a photo of the current belt routing for reference. Many vehicles also have a diagram under the hood.
3. Relieve Belt Tension: Locate the automatic tensioner. Insert your serpentine belt tool or 3/8-inch breaker bar into the square drive hole on the tensioner. Apply steady pressure in the direction that loosens the tension (this direction is usually indicated on the tensioner or requires outward force). This will rotate the tensioner pulley, slackening the belt.
4. Remove the Old Belt: While holding tension, carefully slip the old belt off one of the pulleys, usually an idler pulley or the alternator. Once enough slack is created, you can completely remove the belt from all pulleys.
5. Inspect Pulleys and Tensioner: With the belt off, check all pulleys (alternator, power steering, A/C compressor, water pump, idlers) for any play, wobbling, or excessive noise when spun by hand. Also, inspect the automatic tensioner for proper spring tension and smooth operation. If any pulley or the tensioner feels rough, noisy, or has excessive play, it should be replaced.
6. Route the New Belt: Following your photograph or the diagram, carefully route the new serpentine belt around all pulleys, leaving the tensioner pulley as the last one to engage.
7. Apply Tension and Install the Belt: Once again, use your serpentine belt tool or breaker bar to rotate the automatic tensioner and create slack. While holding the tensioner in the slackened position, slip the new belt over the tensioner pulley. Slowly release the tensioner, ensuring the belt seats correctly in all pulley grooves.
8. Double-Check Routing: Before starting the engine, visually inspect the entire belt path to confirm it is correctly seated in all pulley grooves and routed according to the diagram. Start the engine briefly to ensure the belt tracks properly and there are no unusual noises.

Replacement Interval

For the 2024 Ford F-350 Super Duty, the serpentine belt generally has a long lifespan, but it is a wear item. A typical replacement interval can range from 50,000 to 100,000 miles, or every 5-7 years, whichever comes first. However, it's crucial to inspect the belt regularly (every oil change or 15,000 miles) for signs of wear, regardless of mileage.

Factors like extreme temperatures, dusty environments, or frequent heavy towing can accelerate wear, necessitating earlier replacement. Always refer to your Ford F-350's owner
