Thought I gave you info last week?
Pics by jowens1126
Hopefully this is the best pic you will ever see to explain how to replace this
I searched around and sure diagrams and written explanations but sometimes a pic just helps....

You need the 1/2 plastic A/C / Fuel line disconnect tool.
You also need a set of long, skinny needle nose pliers. I used Harbor Freight Item#63815
I need a 3/4 wrench and 5/8 wrench for the two disconnection points closest to the accumulator for the nuts near the radiator for the condenser.
Remove the large nut suggested above with the 3/4 wrench using the 5/8 to hold onto the fixed hex nut closest to the nut you're working on for support.
Use the 1/2 A/C line separator tool and slip it ON to the metal tube going to the evaporator just BELOW the larger round section at the end of the hose that goes to the condenser.
Press up and seat the 1/2" A/C line separator tool into the condenser hose to you expand the spring lock ring. You'll feel it but spin it around once you feel you're good to make sure you're good.
Because you were smart and disconnected the condenser line near the radiator, you can now spin the hose near the evaporator and pull up. Do it with precision and finesse and it will pop out. Don't force it or you'll bend the line and hate life.
NOW you can see your orifice tube!!! If you look at an angle with a nice shiny light from above and your head isn't in the way. Yes it's kinda deep in there.
Now comes the "fun". Pour some new refrigerant oil meant for your new setup and let it sit for a few minutes. 10-15 is good.
Grab the top of the orifice tube down deep in there with the tips of the needle nose pliers. Keep them mostly compressed so you can grab that tiny lil tab on the top.
Now comes the hardest part. Do NOT F' this up.
JUST BARELY like 1/16, Twist a bit to the right then to the left. Start very gently with barely any movement. You will feel it begin to move easily and then increase then turns just a tiny lil bit more. If you exceed an 1/8 of a turn you'll probably break it and have fun extracting.
Now you feel it's reasonably loose, squeeze hard on the pliers and pull STRAIGHT up. Brace yourself and try to use both arms to pull straight up because you need the most precision and both arms will offer it even if your back hates you.
It will slip a few times and then pop out.
Roughing up the inside tips of your new pliers will help provide some traction. I used a file and cut .5 mm separate lines with 2 cuts 1 each at opposing 45 degree angles.
It will come out. Just keep trying but if you did the above it will be the easiest you'll chance you have. Have fun!
So now you have it out! Just drop the new one in exactly as you see it aligned on the pic with the long red/blue part facing the sky and the short white part facing down. Hopefully that's exactly the same orientation when you pulled it too

"...The inlet tube to the A/C evaporator core is fitted with an A/C evaporator core orifice to control refrigerant flow. This A/C evaporator core orifice can be removed from the inlet tube and A/C evaporator core for replacement if it becomes necessary. However, Fixed Orifice Tube Tool D80L-19990-A or equivalent is necessary to prevent breakage when removing the A/C evaporator core orifice.
The A/C evaporator core orifice is a restriction between the high and low pressure refrigerant and meters the flow of liquid refrigerant into the A/C evaporator core. The diameter of the orifice within the A/C evaporator core orifice is 1.575mm (0.062 inch). The A/C evaporator core orifice can be identified by the RED body color and white outlet tip.
The A/C evaporator core orifice is located in the evaporator core inlet tube and has filter screens on the inlet and outlet ends of the body. The filter screens act as strainers for the liquid refrigerant flowing through the opening. 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 repairs cannot be made to the A/C evaporator core orifice and it must be replaced as a unit.
The suction accumulator/drier is mounted to the front side of the A/C evaporator case and attaches directly to the outlet tube.
Refrigerant enters the accumulator/drier canister through the inlet tube and the heavier, oil-laden refrigerant falls to the bottom of the canister. A small diameter aspirator tube is located close to the bottom of the canister and runs to the top of the vapor return tube. This aspirator tube is covered with a filter screen and allows a small amount of the heavier liquid refrigerant and oil mixture to re-enter the A/C manifold and tube at a controlled rate. When the heavier liquid refrigerant and oil mixture enters the compressor evaporator to compressor suction line (19867), it has a second opportunity to vaporize and circulate through the A/C compressor without causing damage to the A/C compressor due to refrigerant slugging.
A desiccant bag is mounted inside the suction accumulator/drier canister to absorb any moisture that may be in the refrigerant system.
A fitting located on the side of the canister is used to attach the A/C cycling switch. A long-travel Schrader valve stem core is installed in the fitting opening to prevent refrigerant loss when the A/C cycling switch is removed.
NOTE: Replacement of the suction accumulator/drier is not required when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator/drier.
NOTE: The compressor oil may have a dark color while maintaining a normal oil viscosity. This is normal for this A/C compressor because carbon from the compressor piston rings may discolor the oil.
There is evidence of moisture in the system, such as internal corrosion of metal refrigerant lines, or the refrigerant oil is thick and dark.
When replacing the suction accumulator/drier, the procedure given here must be followed to make sure that the total oil charge in the system is correct after the new accumulator/drier is installed.
Drain the oil from the removed suction accumulator/drier into a suitable measuring container. It will be necessary to drill one or two 1/2-inch holes in the bottom of the old suction accumulator/drier, or remove the bottom to make sure that all the oil has drained out.
Add the same amount of clean new refrigerant oil plus 59 ml (2 oz.) to the suction accumulator/drier. Use only the oil specified for the specific vehicle being serviced.
A/C Cycling Switch
The A/C cycling switch is mounted on a Schrader valve fitting on the side of the suction accumulator/drier assembly. A valve depressor, located inside the threaded end of the A/C cycling switch, presses in on the Schrader valve stem as the A/C cycling switch is mounted and allows the suction pressure inside the suction accumulator/drier housing to activate the A/C cycling switch. The electrical contacts will open when the suction pressure drops to 163-175 kPa (23.5-25.5 psi). They will close, activating the A/C clutch (2884), when the suction pressure rises to 276-324 kPa (40-47 psi). Lower ambient temperatures (below approximately 1°C (30°F) during cold weather seasons will also prevent A/C compressor operation, because of the pressure/temperature relationship of the refrigerant in the system.
NOTE: Temperature must drop to -4°C (25°F) to open pressure switch contacts. Contacts open at approximately -4°C (25°F) decreasing and close increasing 7.2-10°C (45-50°F).
The electrical contacts control the electrical circuit to the A/C clutch field coil. When the contacts are closed, the A/C clutch field coil is energized and the A/C clutch is engaged to drive the A/C compressor. When the contacts are open, the A/C clutch field coil is de-energized, the A/C clutch is disengaged and the A/C compressor does not operate. The A/C cycling switch, when functioning properly, will control the pressure at a point where the plate-fin surface temperature of the A/C evaporator core will be maintained slightly above freezing which prevents icing and the blockage of airflow.
A/C Condenser Core
The A/C condenser core is attached to the radiator support in front of the radiator (8005) with two mounting brackets at the top and bottom of the A/C condenser core. The top mounting brackets attach to the rear side of the radiator support and the lower brackets attach to the front side of the radiator support.
