1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace the Serpentine Belt

Tools Required: Socket set, wrench, serpentine belt tool.
Instructions:
1. Locate the serpentine belt tensioner and use the serpentine belt tool to relieve tension.
2. Remove the old serpentine belt from the pulleys.
3. Inspect the pulleys for wear or damage.
4. Install the new serpentine belt according to the routing diagram.
5. Reapply tension to the belt and ensure it is seated properly.

3. Inspect and Replace Fluid Levels

Tools Required: Fluid pump, funnel, torque wrench.
Instructions:
1. Check the transmission fluid level using the dipstick; add fluid if low.
2. Inspect the power steering fluid reservoir and top off as needed.
3. If any fluids are contaminated, drain and replace with manufacturer-recommended fluids.

4. Inspect Accessories

Tools Required: Multimeter, socket set.
Instructions:
