MATERIAL SPECIFICATION

Item	Specification
PAG Refrigerant Compressor Oil for R134a Systems F7AZ-19589-DA	WSH-M1C231-B
Refrigerant Compressor Oil (Mineral Oil) F73Z-19577-AA	ESH-M2C31-A2

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: New O-ring seals, lubricated in clean mineral oil, must be installed before reconnecting any A/C fitting that has been disconnected.

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.

NOTE: If an evaporator core leak is suspected, the evaporator core must be vacuum leak tested before it is removed from the vehicle.

NOTE: Lubricate the coolant hoses with plain water only if needed.

Position the vehicle on a hoist with the gear selector in NEUTRAL. For additional information, refer to JACKING & LIFTING .
If you are servicing the auxiliary evaporator core, the auxiliary A/C lines, O-ring seals or climate control housing, recover the refrigerant. For additional information refer to BODY SYSTEM - INTERIOR .
Remove the LH quarter trim panel. For additional information refer to BODY SYSTEM - INTERIOR .
If you are servicing the auxiliary heater core, the auxiliary evaporator core, the auxiliary climate control housing or the auxiliary heater hoses, clamp off the heater hoses at the front of the underbody auxiliary heater outlet and inlet pipes.

To install, reverse the removal procedure.
- If necessary, install new O-ring seals lubricated in clean mineral oil.
- If necessary, lubricate the refrigerant system with the correct amount of clean PAG oil. For additional information refer to REFRIGERANT OIL ADDING .
If necessary, fill the engine cooling system. For additional information refer to FILLING AND BLEEDING WITH RADKITPLUS or FILLING AND BLEEDING WITHOUT RADKITPLUS .
If necessary, evacuate, leak test and charge the refrigerant system. For additional information refer to AIR CONDITIONING (A/C) SYSTEM RECOVERY, EVACUATION AND CHARGING .
