Solution

1. Preparation

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

2. Inspect and Replace Serpentine Belt

Tools Required: Socket set, serpentine belt tool or wrench
Remove the engine cover if applicable.
Locate the tensioner pulley and relieve tension using the serpentine belt tool.
Carefully remove the belt from the pulleys.
Inspect the belt for signs of wear—replace if cracked or frayed.
Install the new belt by routing it according to the belt routing diagram usually found on a sticker in the engine bay.
Ensure all pulleys are aligned properly and the belt is seated correctly.

3. Tire Inspection and Rotation

Tools Required: Jack, jack stands, tire iron
Lift the vehicle using a jack and secure it with jack stands.
Remove the tires and inspect for signs of wear or damage.
Rotate or replace tires as necessary based on condition.
Reinstall tires and torque lug nuts to manufacturer specifications.

4. Electrical Inspection

Tools Required: Multimeter, electrical contact cleaner
Inspect wiring harnesses and connectors for signs of melting or damage.
Use a multimeter to check for shorts in wiring.
Clean any corroded connectors with electrical contact cleaner.
Replace any damaged wiring or connectors as needed.
