Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle battery to prevent electrical shorts.
Allow the engine to cool down before starting work.

2. Recover Refrigerant

Connect the refrigerant recovery machine to the AC system.
Follow the machine’s instructions to recover the refrigerant from the system safely.

3. Identify and Repair the Leak

3.1. Locate the Leak: Use an electronic leak detector to pinpoint leaks at AC components.
3.2. Replace Damaged Components: If a leak is found in a hose, connection, or compressor seal, replace the damaged component.
- Use new O-rings and seals when reassembling connections.

4. Recharge the AC System

4.1. Evacuate the System: Use a vacuum pump to evacuate the system for at least 30 minutes to remove moisture.
4.2. Recharge with Refrigerant: Follow the manufacturer’s specifications to recharge the system with the correct type and amount of refrigerant (usually R-134a or R-1234yf).

5. Test the System

Reconnect the battery and start the engine.
Turn on the AC to the maximum setting and monitor system operation for any abnormal noises or performance issues.
