It is important to follow the diagram closely when installing and replacing the serpentine belt to ensure proper alignment and tension.
Installation and Replacement
Before installing or replacing the serpentine belt, it's important to inspect each pulley for wear, damage, or misalignment. If any of these issues are present, they should be addressed before continuing with the installation. Once you have verified that the pulleys are in good condition, you can proceed with the following steps:
- Locate the serpentine belt tensioner and use a wrench to release tension on the belt
- Safely remove the old serpentine belt from the engine
- Compare the old belt to the new belt to ensure proper length and width
- Follow the 2003 Dodge Ram 1500 4.7 serpentine belt diagram to route the new belt around each pulley in the correct order
