ORIFICE TUBE REPLACEMENT
Note. Ford evaporator core orifice tube is located in evaporator inlet pipe. Replace orifice tube whenever compressor is replaced.
- Discharge A/C system, using approved refrigerant recovery/recycling equipment. Disconnect high pressure line. Remove and discard "O" rings. Pour a small amount of refrigerant oil into inlet to lubricate "O" rings.
- Insert orifice tube remover/installer into tube. (Scheme 6) Turn tool to right to engage tangs on tube. Turn tool nut to slowly pull orifice tube out. If orifice tube breaks off when removal is attempted, use orifice tube extractor to pull the broken section out. (Scheme 7)
- Ensure new orifice tube is fitted with new "O" ring(s) lubricated with clean refrigerant oil. Insert tube with short end toward evaporator until seated. Reconnect high pressure line.
Note. If broken orifice tube extractor fails to remove broken orifice tube, install orifice tube kit. See ORIFICE TUBE KIT.
