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. Position the vehicle on a hoist with the gear selector in NEUTRAL.
2. Recover the refrigerant.
3. Remove the air cleaner outlet tube.







4. Disconnect the A/C pressure cutoff switch electrical connector.







5. Remove the nut and detach the wire harness.







6. Remove the nut and disconnect the compressor manifold and tube assembly fitting at the condenser core.
- Discard the O-ring seal.







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







8. Remove the nut and detach the compressor manifold and tube assembly.
9. Remove the compressor manifold and tube assembly.

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.
