Orifice Tube Replacement Kit (Continental)
NOTE:
On Continental, if orifice tube is faulty or plugged, liquid line and orifice tube must be replaced as an assembly or an orifice tube replacement kit must be installed.
- Discharge A/C system, using approved refrigerant recovery/recycling equipment. Remove condenser-to-evaporator liquid line from vehicle. Locate orifice tube in metal portion of liquid line, near bend (indented notches or circular depression). See Fig 1.
- Cut a 2.5" (63.5 mm) section from liquid line, at least 1" (25.4 mm) from start of bend in line, and discard. Clean out liquid line to remove contaminants.
- Lubricate orifice tube replacement kit compression nuts and rings with refrigerant oil and install on liquid line. See Fig 2. Ensure flow direction arrow points toward evaporator. Ensure liquid line is properly aligned for installation. Tighten compression nuts to 65-69 ft. lbs. (88-94 N.m).
- To complete installation, reverse removal procedure. Lubricate "O" rings with refrigerant oil. Evacuate, charge and leak test system. Ensure A/C system is operating properly.
