Compressor Fitting HVAC: Service and Repair
COMPRESSOR MANIFOLD AND TUBE ASSEMBLYREMOVAL
CAUTION: Refrigerant compressor oil (mineral oil) F73Z-19577-AA (Motorcraft YN-9-A) should be used to lubricate R-134a refrigerant system O-ring seals only and should not be added to the R-134a refrigerant system as an A/C compressor lubricant. PAG refrigerant compressor oil F7AZ-19D589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B only should be used as an A/C compressor lubricant.
NOTE: Installation of a new suction accumulator is not required when repairing the air conditioning system, except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator.
1. Recover the refrigerant.
2. Disconnect the electrical connector.
3. Disconnect the compressor manifold and tube assembly from the A/C compressor.
1 Loosen the bolt.
2 Disconnect and position aside the compressor manifold and tube assembly.
- Discard the O-ring seals.
4. Disconnect the compressor manifold and tube assembly spring lock coupling from the suction accumulator.
- Discard the O-ring seals.
5. Disconnect the compressor manifold and tube assembly from the compressor to condenser discharge line and remove the compressor manifold and tube assembly.
- Discard the O-ring seal.
INSTALLATION
1. To install, reverse the removal procedure.
- Install new O-ring seals lubricated in clean mineral oil.
- Lubricate the refrigerant system with the correct amount of clean PAG oil.
2. Evacuate, leak test, and charge the refrigerant system.
