SOURCE: 97 suburban rear a/c doesnt get cold but front works great

the expansion valve is in the rear ac housing and it is bolted directly to the rear evaporator. it is an actual expansion valve and not an orifice tube. the part is about $45. the interior on the passenger side has to come out along with the entire rear ac sytem.

Show me where the orifice tube located


Same post again? Look at two AC pipes entering heater box. One is low side (large) and one is high side (smaller). Disconnect the high side pipe union and inside the pie going into heater box is the orifice tube.

Where is the location of the ac orifice tube on 06 chevy silverado


The orifice tube is located in the line of the high pressure side of the system it maybe at the condenser or in the high pressure line. You should be able to feel a crimp in the line and the is the stop for the orifice. I believe the o6 is in the line and as I said there is a crimp in the line where the orifice is located.

Location of orifice tube in 2000 chevy venture


best advice is the method i would use to located the orifice tube in the 2000 chevy venture. check the automotive repair book section in your local library. Most libraries have repair manuals on their automotive shelf section. find the a/c manual for your year and model car. make a copy of the page that has the information you need. you will need to make a copy because the library will not let those manuals be checked out. you might want to google for the location of the orifice tube location. I hope this helps.

Find orifice tube


Usually the orifice tube is in the lower metal line going to the condenser, possibly behind the grille. The line is bulged out wider where the tube is.

What is the purpose, and what is the proper location of the orifice tube in the air conditioning system on my 1991 chevy silverado?


The orifice tube restricts the flow of refrigerant to the evaporator. This restriction allows high pressure liquid freon to change into low pressure freon before entering the evaporator. The orifice tube is located inside the hose running between the condenser and the evaporator. You'll need an orifice tube removal kit if you are looking to remove it.

Orfice tube location


the fixed orifice is located in the inlet tube to the evaporator core, this is where the small high pressure AC line from the compressor connects to the tube sticking out of the engine firewall, u will most likely need a special tool to remove it, here is a web link to the tool, don't damage the evaporator core by trying to remove the orifice tube without this if it is stuck down in the tube.

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.
