Compressor Fitting HVAC: Service and Repair

COMPRESSOR MANIFOLD AND TUBE ASSEMBLY

REMOVAL

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 compressor manifold and tube assembly spring lock coupling from the suction accumulator.
- Discard the O-ring seals.







3. Disconnect the compressor manifold and tube assembly from the condenser core.
- Discard the O-ring seal.







4. Disconnect the pressure cutoff switch electrical connector.







5. Disconnect the fuel line spring lock coupling.







6. Remove the nut and position the bracket aside.







7. Loosen the bolt and remove the compressor manifold and tube assembly.
- Discard the O-ring seals.

INSTALLATION







1. To install, reverse the removal procedure.
- If a new compressor manifold and tube assembly is to be installed, transfer the pressure cutoff switch to the new compressor manifold and tube assembly.
- 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.
