Replacing the serpentine belt on a 6.0L Power Stroke diesel engine requires careful attention to the belt routing diagram to avoid misalignment. Ensure the engine is cool and the vehicle is parked on a level surface with the ignition off.
Required Tools
- Serpentine belt routing diagram (located in the engine bay or owner's manual)
- Wrench set or ratchet
- Serpentine belt tensioner tool
- New 6.0 Power Stroke compatible belt
- Flashlight for visibility
Accessing the Serpentine Belt Diagram
Locate the diagram decal, typically affixed to the radiator shroud or hood underside. Quickly reference it to identify the belt path around pulleys, including the tensioner, alternator, water pump, and idlers. Memorize or sketch the route before proceeding to ensure accurate reinstallation.
Replacement Procedure
- Insert the tensioner tool onto the belt tensioner pulley.
- Apply leverage to release tension and slide the old belt off one pulley at a time, following the diagram path.
- Remove the belt completely and compare it with the new belt for size verification.
- Position the new belt, starting from the crankshaft pulley and routing it per the diagram.
- Re-engage the tensioner to allow the belt to seat snugly, ensuring no twists or slack.
Final Checks
Manually rotate the engine with a wrench to check for smooth movement and belt alignment. Start the engine briefly to confirm no squealing or slipping, indicating proper tension. Replace tensioner if excessive wear is noted during the process.
