Solution
1. Preparation
  • Gather tools and parts needed for the repair.
  • Ensure the vehicle is parked on a level surface and the engine is off.
2. Recover Refrigerant
  • Tools Required: Refrigerant recovery machine
  • Connect the recovery machine to the AC service ports and recover the refrigerant according to the machine's instructions.
  • Safety Warning: Always wear gloves and goggles when handling refrigerant.
3. Locate and Repair the Leak
  • Inspect identified leaking components (hoses, seals, compressor) and make repairs.
  • Replace any damaged hoses or fittings.
  • If the leak is in the condenser or evaporator, replace these components as necessary.
  • Use appropriate sealant or o-rings as needed to ensure a proper seal.
4. Recharge the System
  • Tools Required: Manifold gauge set, vacuum pump
  • Connect the manifold gauge to the AC service ports.
  • Evacuate the system by running the vacuum pump for at least 30 minutes.
  • Recharge the system with the correct type and amount of refrigerant as specified in the vehicle manual.
5. Final Check
  • Start the engine and run the AC on max for a few minutes.
  • Confirm that the AC is blowing cold air and check for any signs of leaks around the repaired areas.
