- Install the new serpentine belt following the routing diagram, ensuring proper tension.
- Double-check the operation of all driven accessories.

4. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump and container.
Steps:
- Locate the transmission dipstick and check the fluid level and condition.
- If low or burnt, pump out old fluid using the transmission fluid pump.
- Refill with manufacturer-recommended transmission fluid to the correct level.

5. Inspect and Tighten or Replace Loose Components

Tools Required: Socket set, torque wrench.
Steps:
- Visually inspect all engine components and fasteners for looseness.
