Solution

1. Preparation

Tools Required: OBD-II scanner, flashlight, safety gloves, and safety goggles.
Ensure the vehicle is parked on a flat surface and the engine is cool before starting work.

2. Inspect and Replace Belts

Sub-steps:
1. Open the hood and visually check the serpentine belt for any cracks or wear.
2. If damage is found, loosen the tensioner using a socket wrench and remove the old belt.
3. Install a new serpentine belt according to the routing diagram located on the engine cover.
4. Tighten the tensioner to the manufacturer's specification (usually around 10-15 ft-lbs).

3. Inspect and Replace Hoses

Sub-steps:
1. Examine all hoses for signs of wear, cracks, or leaks.
2. If any hoses are damaged, loosen the clamps and remove the old hose.
3. Install a new hose, ensuring it is secured with the clamps and properly routed.
4. Check all connections and ensure there are no leaks.

4. Inspect and Service Cooling System

Sub-steps:
1. Check the coolant level in the reservoir and top it off if low with the recommended coolant type.
2. Inspect the radiator and hoses for any signs of damage or leaks.
3. If there is any evidence of overheating (e.g., steam), allow the engine to cool, then check for blockages in the radiator.
4. Replace the thermostat if necessary, draining the coolant and following the proper replacement procedure.
