The evaporator is that finned radiator under the dash The tx valve is plumbed into the pipe going into the evaporator and has a fixed hole. The tx valve is controlled by the thermostat that is located in the fins externally on a small metal tube. If you have temp problems replace the thermostat first

WHERE IS ORIFICE TUBE LOATION ON LINCOLN NAVIGATOR


The A/C evaporator core orifice is located in the A/C evaporator core inlet tube. you will need to seperate the tube at the slip nut on the line. It is located in front of the battery routed along side the engine to the evaporator core

I am replacing the compressor, drier , and orfice tube but I can not locate the orfice tube


The orifice tube is located inside the low pressure line, usually just before the evaporator. DO NOT forget to measure and replace the oil that you get in the dryer, as a percentage of total system capacity for oil. It is special oil.

Loacation of the orifice tube


The AC evaporator orifice always has to be after the electronic freon release valve after the receiver/dryer, and the evaporator itself.
It is optimal for it to be as close to the evaporator as possible, so sometimes it is even part of the input for the evaporator.
However, it is best if it is separate, because the orifice often gets clogged.
But the most common cause of clogging is ice, so try a vacuum pump to desiccate any moisture out first.
If the clog is ice, you can tell by heating the orifice and melting the ice.
Careful not to get it too hot though.
You don't want to damage hoses, and if freon gets into a flame, it can be toxic.

Which way does the orifice tube go? Orange end or white end to the firewall?


9 is the orifice. Freon is headed toward the evaporator in the car. The orifice has an arrow on it. Good luck, please rate. Thanks A/C Evaporator Core Orifice NOTE: The A/C evaporator core orifice (19D990) should be replaced whenever an A/C compressor (19703) is replaced.

The A/C evaporator core orifice has the following characteristics:
  • is color-coded orange
  • has a diameter of 1.46 mm (0.058 inch)
  • is located in the condenser to evaporator tube (19835)
  • has filter screens located on the inlet and outlet ends of the tube body
The A/C evaporator core orifice is the restriction in the refrigerant circuit that creates the pressure drop necessary for cooling by metering the flow of liquid refrigerant into the A/C evaporator core (19860), which reduces the pressure. Operation is as follows:
  • The inlet filter screen acts as a strainer for the liquid refrigerant flowing through the A/C evaporator core orifice.
  • O-rings on the A/C evaporator core orifice prevent the high-pressure liquid refrigerant from bypassing the A/C evaporator core orifice .
  • Adjustment or services cannot be made to the A/C evaporator core orifice assembly. It must be replaced as a unit.

Where is the orifice tube in a 1994 mustang

Where exactly is the orifice tube located at on a 1996 (DOHC v6)?


it's in the high pressure liquid line.

A/C Evaporator Core Orifice The A/C evaporator core orifice (19D990) should be replaced whenever the A/C compressor (19703) is replaced for lack of performance (internal damage). The A/C evaporator core orifice, located in the condenser to evaporator tube (19835), cannot be serviced in detail as a component of the line. If replacement is necessary, follow the procedure outlined for Liquid Line Removal and Installation. An orifice tube replacement service kit may be used as an optional service procedure. Refer to Section 12-00 for information regarding the use of an A/C Evaporator Core Orifice Replacement Kit E5VY-19D695-A.
-----------------------------------------------------------------------------------
A/C Evaporator Core Orifice Replacement Kit Installation
  1. Discharge A/C refrigerant system. Refer to System Discharging and Recovery as outlined.
  1. Remove condenser to evaporator tube (19835) from vehicle.
  1. Locate A/C evaporator core orifice (19D990) by three indentations or a circular recess in metal portion of the condenser to evaporator tube.


    A/C Evaporator Core Orifice Location

  1. Note angular position of ends of condenser to evaporator tube so that it can be reassembled in correct position.
  1. Cut a 63.5 mm (2.5 inch) section from condenser to evaporator tube at A/C evaporator core orifice location. Do not cut closer than 25.4 mm (1 inch) from start of a bend in tube.

  1. Remove contaminants from the two pieces of the condenser to evaporator tube.
  1. NOTE: The inlet half of the condenser to evaporator tube will be positioned against the A/C evaporator core orifice tabs when correctly assembled.

    Lubricate fitting with clean refrigerant oil and assemble orifice tube kit (with A/C evaporator core orifice installed) to condenser to evaporator tube. Make sure flow direction arrow is pointing toward evaporator end of the condenser to evaporator tube, and taper of each compressor ring is toward compression nut.

AC 2002 Ford Taurus SE


I believe the orifice tube on this model requires the a/c pipe to be cut to install a new tube. You need to discharge the system, replace the tube, then evacuate miosture with a vacuum pump, then recharge with R134A refirgerant. Not a job for a non technical person.

The oriifce is in the line just before the evaporator that is in your car a/c heater case. It is where the liquid refrigerant turns into a vapor as it comes out of the orifice and then it absorbs heat from the air going into you car, thus blowing cold air. Moisutre in the warm air condenses and as he iar gets cold and it drains out of your evaporator and out the drain & onto the ground
