Solution

1. Preparation

Tools Required: Socket set, screwdriver set, flashlight, OBD-II scanner
Ensure the vehicle is parked on a level surface and the engine is off. Allow the engine to cool before starting work.

2. Inspect and Replace Serpentine Belt

Sub-steps:
1. Remove the engine cover if applicable.
2. Locate the serpentine belt and use a wrench to relieve tension on the tensioner pulley.
3. Carefully remove the belt from the pulleys.
4. Inspect the belt for cracks, fraying, or signs of glazing.
5. If damaged, replace the belt with a new one (use manufacturer-recommended part).
6. Reinstall the new belt, ensuring it is routed correctly according to the belt routing diagram.

3. Check and Adjust Brake System

Sub-steps:
1. Lift the front and rear of the vehicle using jack stands.
2. Remove the wheel to access the brake components.
3. Inspect the brake pads and rotors for excessive wear and overheating signs.
4. If the brake pads are worn down or if the rotors are warped, replace them.
5. Ensure calipers are functioning properly and do not stick, causing brakes to drag.

4. Examine Engine Compartment Components

Sub-steps:
1. Inspect hoses and wires for signs of melting or burning.
2. Check for any signs of oil or fluid leaks onto hot engine components.
3. Tighten any loose clamps or connections.
