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.

Where is orifice tube on 2003 Mazda tribute


It is in the high pressure line going to the evaporator like everyone said. My Haynes manual made it look like it was at the connection right at the firewall but it is further upstream than that. There is a compression fitting upstream of the A/C tube fitting that you have to undo. Once you open that part you'll see the orifice tube. Hope this helps

05 taurus orifice tube location




  • To replace the orifice tube ---
  1. Remove the washer and overflow bottle. The high side service port is on a pipe about eight inches long to make it easier for service. The fitting and orifice tube are near this pipe. The fitting is covered with a protective rubber cover that makes it hard to see the fitting.
  2. Push the cover back.
  3. Disconnect the fitting.
  4. Replace the orifice tube.
  5. Lubricate the new o-ring and torque the fitting to 18 foot pounds.
  • Ford says to use a special too to get the orifice tube out of the hose. I find needle nose pliers gets the job done real well unless it is really stuck then use the tool.

  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

Regards, Tony

Ac comp doesnt come on it saya low ref but i had that checked & it was ok


If the orifice tube is restricted,this could cause the problem ,but make sure it is not low on freon,the orifice tube is only a couple of dollars,but you will have to remove the freon to replace the orifice tube,most always the orifice tube needs replacing,almost all the time they are checked the orifice tubes are clogging up.If this was helpful,please rate,the ac system you have,has two sensors,and it is real sensitive.

Ac cycles on 92 blazer ,new compressor,low switch bad?


Did you replace the dryer,and the orifice tube?If the orifice tube was not replaced,this is most likely the problem,what are the pressures while it is running,and how much freon is in the system?If the system does not have enough freon it it,it will do this,but if it does,the cycling ac compressor is because of the orifice tube,if the system was not flushed out,and there was a new orifice tube installed ,then it is stopped up again.Let me know something so I can help.

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.
