Should be in one of the metal lines at the connection for the condenser. The line is wider where the tube is.

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.

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.

Where is orifice tube located in the a/c system


Hi, Orifice tubes are located in the high pressure line where it goes into the evaporator (close to firewall) or the condenser ( close to radiator) or in the line itself. I believe in my jimmy (about the same as a blazer) it was near the firewall where the high pressure line unscrews. Unscrew the line (think its a large coupler) and it should be inside there. Clean the cavity of any dirt or debris well and note the direction of the old orifice for installation.
Please rate this answer......Thanks! Mike

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 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.
