1. Preparation

Tools Required: Jack and jack stands, wheel chocks, flashlight, OBD-II scanner, basic hand tools (sockets, wrenches).
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Allow the engine to cool down completely before starting repairs.

2. Inspect and Replace Belts

Sub-steps:
1. Open the hood and inspect the serpentine belt for cracks, fraying, or signs of wear.
2. If the belt is damaged, remove it by loosening the tensioner pulley using a socket wrench.
3. Replace the old belt with a new one, ensuring it is properly routed according to the diagram located on the engine cover.
4. Recheck the tension of the new belt and ensure it is secure.

3. Check and Adjust Brake Components

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the brake assembly.
3. Inspect brake pads and rotors for excessive wear or overheating signs. Replace if necessary.
4. Ensure that the brake caliper is functioning correctly and not sticking. Clean and lubricate the caliper sliders if needed.

4. Tire Inspection and Alignment

Sub-steps:
1. Inspect all tires for uneven wear patterns or damage.
2. Ensure there is no rubbing against the wheel well or suspension components.
3. If necessary, rotate or replace tires and check wheel alignment to prevent future issues.
