Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Tools Required: OBD-II scanner, socket set, jack and jack stands, torque wrench, multimeter.

2. Inspect and Replace Drive Belts

Sub-steps:
1. Open the hood and locate the serpentine belt.
2. Check for wear, cracks, or fraying. If damaged, replace it.
3. To replace, loosen the tensioner pulley and remove the old belt.
4. Route the new belt according to the belt routing diagram.
