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 R-134a refrigerant systems as an A/C compressor lubricant. PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B only should be used as an A/C compressor lubricant.

1. Remove the condenser to evaporator tube.
- For a fixed orifice tube, carry out Steps 2 and 3.
- For a broken orifice tube, carry out Steps 4 and 5.







2. Engage the special tool to the A/C evaporator core orifice.







3. Hold the tool T-handle stationary and rotate the tool body to remove the A/C evaporator core orifice.







4. To remove a broken A/C evaporator core orifice, screw the end of the special tool into the broken A/C evaporator core orifice.







5. Hold the tool T-handle stationary and rotate the tool body to remove the broken A/C evaporator core orifice.

INSTALLATION
