Solution

1. Preparation

Gather all necessary tools and parts before starting.
Park the vehicle on a level surface and ensure the engine is cool.
Disconnect the battery to ensure safety.

2. Inspect and Replace Belts

Tools Required: Socket set, wrench set, belt tensioner tool
Check the condition of the serpentine belt and accessory belts for signs of wear or fraying.
If worn, remove the old belt:
1. Loosen the tensioner using a belt tensioner tool.
2. Slide the belt off the pulleys.
Install the new belt:
1. Route the new belt according to the belt routing diagram.
2. Tighten the tensioner back to specifications (typically 10-15 ft-lbs).

3. Brake Component Inspection

Tools Required: Jack, jack stands, lug wrench
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access brake components:
1. Inspect brake pads and rotors for signs of excessive wear or glazing.
2. Check for any debris that could be causing friction.
Replace any worn components as necessary.

4. Tire Inspection

Tools Required: Tire pressure gauge, tread depth gauge
Inspect each tire for uneven wear or damage:
1. Check tire pressure and inflate to recommended PSI if low.
2. Measure tread depth to ensure it is within acceptable limits.
Rotate or replace tires as needed.
