I followed the liquid line from the evaporator , back towards the condenser & quickly lost it it behind the power brake vacuum booster . The line was cold , with the A/C running .

I followed the liquid line forward , from the high pressure service port , towards the evaporator . I lost the line under the ABS module / assembly .The line was warm .

The orifice tube had to be some where in between , under the other stuff .

I finally found a crude picture of this entire liquid line . I could see , in the picture , where the orifice tube was .

I bought a little round mirroe on a telescoping handel . With it and a flashlight I finally could see the V orifice tube . It is tucked away to the right of the vacuum brake booster ( looking straight at the booster ) in the corner formed bu the fire wall , fender and wheel well .

It is going to be a huge pain to get to .

Thanks ,

Need an air conditioning diagram of 1997 Chevy Lumina for location of orfice tube placement.

If you look at the low pressure side line going from the dryer to the condenser you will find a crimped place and it is probably down by the condenser and that is where the orifice tube is.

The orifice tube is located at the firewall, INSIDE the refrigerant line, where the end of the flex line connects to the metal pipe which, in turn, connects to the evaporator coil inside the air exchanger.

Some GM orphice tubes are located in the ac line to the evaporator coil and some at the opening of the evap. where your line is attatched. You will see that the line is a little larger in diam. at that point.

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.

    A/C Evaporator Core Orifice Section Removed From the Liquid Line
  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.

Where, exactly, is the orifice tube located on my truck?

the orfice tube is locate in the line between condenser and evaporator. near the spring lock coupling. you must unbolt the cruise servo and overflow bottle, reposition them out of way and you will see the line connection..the orfice is inside line near that uniion. the ac system must be evacuated prior to removal, and recharged afterwards..
