Solution

1. Preparation

Tools Required: Socket set, safety goggles, gloves, jack and jack stands, OBD-II scanner.
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

Sub-steps:
1. Remove the engine cover if applicable.
2. Locate the serpentine belt and inspect it for signs of wear or damage.
3. If damaged, use a socket to release tension on the belt tensioner and remove the old belt.
4. Install the new serpentine belt following the routing diagram usually located on the engine bay.
5. Recheck the tension and ensure it is properly aligned.

3. Check and Replace Timing Belt (if necessary)

Sub-steps:
1. If the timing belt shows any signs of damage during inspection, replace it as per manufacturer specifications.
2. Remove the necessary components to access the timing belt (e.g., covers, pulleys).
3. Align timing marks on the camshaft and crankshaft.
4. Install the new timing belt, ensuring proper tension.
5. Reassemble all components removed.

4. Brake System Inspection

Sub-steps:
1. Inspect the brake pads and rotors for signs of wear or overheating.
2. If the brake pads are worn down or the rotors are warped, replace them.
3. Check for proper operation of the brake calipers and ensure they are not sticking.
4. Reassemble any components removed during inspection.

5. Tire Inspection

Sub-steps:
1. Check all tires for proper inflation and even wear patterns.
2. Rotate tires if necessary and replace any that are excessively worn or damaged.
3. Ensure the alignment is set correctly to prevent uneven tire wear.
