ORIFICE TUBE REPLACEMENT
CHRYSLER CORP.
Removal & Installation (Dakota)
1) Disconnect negative battery cable. Discharge A/C system,
using approved refrigerant recovery/recycling equipment. Disconnect
liquid line at condenser outlet tube. Cover open refrigerant fittings
to protect from moisture and dirt.
2) Using 2 wrenches, loosen tube fitting and separate front
half of liquid line from rear half of liquid line. Using needle nose
pliers, remove fixed orifice tube from rear half of liquid line. Note
fixed orifice tube orientation for correct installation.
3) To install, reverse removal procedure. Ensure fixed
orifice tube is positioned correctly. Evacuate, charge, and leak test
A/C system. Ensure A/C system operates properly.
NOTE: On Ram Pickup, if the fixed orifice tube is faulty or
plugged, the liquid line and orifice tube must be replaced as
an assembly.
Removal & Installation (Ram Pickup)
Disconnect negative battery cable. Discharge A/C system,
using approved refrigerant recovery/recycling equipment. Disconnect
liquid line from evaporator inlet and condenser outlet tubes. Cover
open refrigerant fittings to protect from moisture and dirt.
Disconnect liquid line retaining clips. Remove liquid line and orifice
tube. To install, reverse removal procedure. Evacuate, charge, and
leak test A/C system. Ensure A/C system operates properly.
FORD MOTOR CO.
NOTE: Replace orifice tube whenever compressor is replaced. Fixed
orifice tube is located in the condenser-to-evaporator liquid
line.
NOTE: DO NOT use pliers to remove fixed orifice tube or twist
orifice tube in liquid line. Doing so will cause plastic
orifice tube body to break inside condenser-to-evaporator
liquid line.
Fixed Orifice Tube Replacement (Except Continental, Mustang &
Villager)
1) Disconnect negative battery cable. Discharge A/C system,
using approved refrigerant recovery/recycling equipment. On Contour
and Mystique, move power steering fluid reservoir to one side without
disconnecting hoses.
2) On all models, disconnect condenser-to-evaporator
discharge (liquid) line. Remove and discard "O" rings from line. Pour
a small amount of refrigerant oil into inlet to lubricate orifice "O"
rings.
3) Insert orifice tube remover/installer into tube and turn
tool to right to engage tangs on orifice tube. See Fig. 18. Hold "T"
handle of tool and slowly tighten nut down onto discharge line 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. See Fig. 19.
4) Ensure replacement orifice tube is fitted with "O" ring(s)\
lubricated with clean refrigerant oil. Insert tube with short end
toward evaporator, until seated. Reconnect high pressure line. On
Contour and Mystique, tighten connection to 18 ft. lbs. (24 N.m).
