Leak detection 

1. Recover the refrigerant. Refer to Air Conditioning (A/C) System Recovery, Evacuation and Charging 
2. Disconnect the refrigerant lines from the A/C compressor. Refer to the appropriate Climate Control System article for the procedure.
3. Install the adapters from the A/C Flush Adapter Kit on the ports of the A/C compressor, using the existing retaining bolts.
   • For access to the correct adapters and A/C Flush Adapter Kit 1 through 3. Refer to: Climate Control Tools and Equipment .

4. Connect the high and low pressure lines of the air conditioning service unit to the corresponding fittings on the adapter.
   • For access to the correct Ford approved A/C Refrigerant Management System Refer to: Climate Control Tools and Equipment .

5. Charge the A/C compressor following the air conditioning service unit instructions. Open the low pressure valve, the high pressure valve and set the refrigerant charge amount to 0.23 kg (8 oz).
6. NOTE: Depending on refrigerant type used:
   • Use a Rotunda-approved Electronic Leak Detector for R-134a refrigerant SAE Certified to J2791.
   • Use a Rotunda-approved Electronic Leak Detector for R-1234yf refrigerant SAE Certified to J2913.

   Using the Refrigerant Leak Detector, check for leaks at the compressor shaft.

   • For access to the Ford approved Refrigerant Leak Detector Refer to: Climate Control Tools and Equipment .

7. When the leak test is complete, recover the refrigerant from the compressor.
8. If an external leak is found, install a new A/C compressor.
