2. Locate the Serpentine Belt: Identify the serpentine belt running around various pulleys (alternator, power steering pump, water pump, etc.).

3. Locate the Belt Tensioner: This is a pulley with a mechanism to create tension on the belt, allowing you to remove and install the belt. It may be spring-loaded or require a specific tool or wrench to release tension.

6. Install the New Belt: Carefully route the new belt around all the pulleys in the same order as the old belt. Make sure it sits correctly in the grooves of each pulley.

7. Release Tensioner and Check Alignment: Releasing the tensioner will allow the belt to tighten onto the pulleys. Visually inspect the belt routing to make sure it's correctly aligned and all pulleys are engaged.
