no problem told at all, surely not lookin for fun and kicks?
EGR Orifice,
AC expansion valve orifice.
or what tell what it does, or the problem told
2.2Liter, L61 engine.
I think you meant this. for HVAC AC cooling problems.
air conditioning, is located at the evaporator core close by.
Expansion (Orifice) Tube Replacement
the service manual covers this, see my last link
EGR on some it is in the rusty exhaust pipe just to the rear of the main EGR valve.

Terry,I think its in the evaporator, some times in one of the condenser lines, Check the attached links,

Are your asking about TXV valve thermal expansion valve for A/C system ? If you are ,yours doesn't have one . Has an orifice tube ,
The orifice tube is located in the liquid line between the condenser and the evaporator !
The orifice tube is the dividing point for the high and the low pressure sides of the A/C system. As the refrigerant passes through the orifice tube, the pressure on the refrigerant is lowered. Due to the pressure differential on the liquid refrigerant, the refrigerant will begin to vaporize at the orifice tube. The orifice tube also meters the amount of liquid refrigerant that can flow into the evaporator.
Unless you are referring to the
auxiliary A/C system for the back of the vehicle , it uses a
The rear TXV is located at the rear evaporator inlet. The TXV is the dividing point for the high and the low pressure sides of the rear A/C system. As the refrigerant passes through the TXV, the pressure on the refrigerant is lowered. Due to the pressure differential on the liquid refrigerant, the refrigerant will begin to boil at the expansion device. The TXV also meters the amount of liquid refrigerant that can flow into the evaporator.
The orifice tube is located in the evaporator inlet pipe at the liquid line connection. The evaporator is located in the right rear side of the engine compartment. .
The orifice tube is located inside the liquid line where it connects to the condenser. This line is located on the passenger side of the car and has the low side charge port on it. this line unscrews right where the orifice tube is located... Hope this helps
hi, if i am correct, this vehicle does not have a filter for the freon in the rear a/c system. the front a/c compressor produces the pressure and suction for the rear system and there is a filter/drier called an accumulator. also there is another filter called an orifice tube. both of these items are located near the passenger firewall. the accumulator is a larger aluminum cylinder which has two hoses going to it from the compressor, and the orifice tube is located inside the high pressure discharge hose assembly near the condensor(mounted in front of the radiator). but, as far as the rear a/c goes, this vehicle uses an evaporator expansion valve for the rear a/c on most models. now, if i'm wrong, and there is actually an orifice tube in the rear, you would find it inside the hose at the very rear, near the exhaust tailpipe on the passenger side. you would have to discharge the whole system to inspect. might want to take to a shop, good luck.
There is one orifice tube for the font air. It is located in the a/c line coming from the condenser to the evap. core. the rear a/c has and expansion valve attached to the rear evap. core. Hope this helps.
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
Discharge A/C refrigerant system. Refer to System Discharging and Recovery as outlined.
Remove condenser to evaporator tube (19835) from vehicle.
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
Note angular position of ends of condenser to evaporator tube so that it can be reassembled in correct position.
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
Remove contaminants from the two pieces of the condenser to evaporator tube.
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.
The orifice on Suburbans with rear A/C is located near the Y shaped junction block in the tube between the condenser and the front evaparator. It is on the right side near the radiator support. The orifice is in the tube between the junction block and front evaporator. If you look close there is a slight crimp in the tube to keep it from sliding too far into the tube. You should be able to disassemble the tube and remove and replace it.
Sorry for the late post but I just saw your question.
