Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical shorts.

2. Inspect and Replace Serpentine Belt

Tools Required: Socket set, belt tensioner tool, torque wrench
Sub-steps:
1. Use the belt tensioner tool to relieve tension on the serpentine belt.
2. Carefully remove the belt from the pulleys.
3. Inspect the belt for cracks, fraying, or melting.
4. If damaged, replace with a new serpentine belt, ensuring it is routed according to the vehicle's belt diagram.
5. Reapply tension and ensure the belt is securely in place.

3. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench
Sub-steps:
1. Jack up the vehicle and secure it on jack stands.
2. Remove the wheels and inspect for uneven wear, damage, or foreign objects.
3. Check the alignment and suspension components for any signs of damage.
4. Replace tires if they are excessively worn or damaged.
5. Reinstall wheels and lower the vehicle.

4. Fluid Leak Check

Tools Required: Clean cloth, oil catch pan
Sub-steps:
1. Inspect the ground under the vehicle for any fluid leaks.
2. Check the engine oil level and condition, looking for signs of coolant contamination.
3. If leaks are found, identify the source and replace any damaged components or gaskets.
4. Clean any spilled fluids to prevent further overheating of rubber components.
