Solution

1. Preparation

Tools Required: OBD-II scanner, flashlight, screwdrivers, socket set
Ensure the vehicle is parked on a flat surface and the engine is off and cool.

2. Address Cooling System Leaks

Sub-steps:
1. Remove the engine cover (if applicable).
2. Inspect all hoses and connections for signs of wear or leaks.
3. If a leak is found, replace the damaged hose or clamp.
4. Refill coolant if necessary and bleed the system to remove air.

3. Repair Vacuum Leaks

Sub-steps:
1. Inspect all visible vacuum hoses for cracks or loose connections.
2. Replace any damaged hoses with new ones.
3. Ensure all connections are securely fastened.

4. Fix Exhaust Leaks

Sub-steps:
1. Visually inspect the exhaust manifold and pipes for cracks or holes.
2. If a leak is found, replace the damaged section or re-gasket the connection points.

5. Service the AC System

Sub-steps:
1. Inspect the AC compressor and lines for visible signs of refrigerant leaks (oily residue).
2. If a leak is detected, replace the faulty component (compressor or line).
3. Recharge the AC system with the appropriate amount of refrigerant.
