Hose/Line HVAC: Service and Repair
CONDENSER TO EVAPORATOR LINEREMOVAL
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 R-134a refrigerant systems 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.
Vehicles with 3.0L (2V) engine
1. Remove the suction accumulator.
Vehicles with 3.0L (4V) engine
2. Recover the refrigerant.
3. Disconnect the compressor manifold and tube fitting at the suction accumulator.
- Discard the O-ring seals.
4. Clamp off and disconnect the coolant hoses at the degas bottle.

All vehicles
13. Disconnect the condenser to evaporator line spring lock coupling at the evaporator core inlet.
- Discard the O-ring seals.
14. NOTE: On 3.0L (4V) vehicles, the condenser to evaporator line will need to be manipulated around the fuel line.
Remove the condenser to evaporator line.
INSTALLATION
Vehicles with 3.0L (2V) engine
1. To install, reverse the removal procedure.
- Install new O-ring seals lubricated in clean mineral oil.
Vehicles with 3.0L (4V) engine
2. 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.
3. Evacuate, leak test and charge the A/C system.
