Question about 1993 Buick Century

1 Answer

1993 Buick Century, V-6

Can you provide the specific location of the A/C refrigerant expansion orifice in the Liquid line. I cannot find where this is located I've got plenty of debris at the inlet screen of the compressor and want to inspect, clean or replace the expansion orifice prior to charging.
Is it behind the evaporator shield on the firewall? I cannot locate 5" of straight line which may support it's internal location.
Thank You

    Thank you for the advise. I found it located adjacent to the outlet of the condenser coil, the tubing with orifice is running vertically at the base with a line connection. Very difficult space to access!

I would check the line comming out of the accumulator. Also check to see if it in fact has one. Some cars, before 1995 only used the expansion valves which is in with the evap. coil.

Were is expansion valve in a 2002 Chevy trailblazer in the truck


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.

Where is the orifice tube located to put a new one in?


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

1993 buick century orifice tube


The orifice is located at the inlet tube to the evaporator core on the firewall, just suction the system out and remove the pressure line to the evap core, it is right there.

Location of txv valve in af ord taurus 1999


The Thermal Expansion Valve has been replaced by a device called the ORIFICE tube which looks like a tiny line filter. It is an inexpensive part that can be easily removed and replaced for about $3 or less. You will follow the liquid line (smaller line running from the compressor to the firewall) to the midcenter point of the passenger side inner fender well and there will be a large rubber protector over the line. You will need to peel and tear or cut this away to uncover a nut that connects the line and there should be an "indentation" slot in the line on the side where the orifice tube is located. You must be very careful to discharge any pressure from the low side where you normally add refrigerant before you attempt to uncouple the liquid line. You must be very careful to wiggle and pull straight out (do not twist) on the orifice tube. If it breaks you must buy special tools to remove it. Place the new orifice tube back in the same position, replace any worn o-rings, use refrigerant oil to lubricate the new o-rings and retighten the nut but do not overtighten.

Where is the orifice tube on a 98 Buick LeSabre located?


not exactly sure but using info below you can find it.

Remember the flow for the a/c system is :
1. From the compressor a high pressure (HP) gas goes to the condenser in front of the radiator.
2. From the condenser a HP liquid goes to an expansion device (orifice tube or expansion valve)
3. From expansion device the low pressure gas enters the firewall to the evaporator.
4. From evaporator the low pressure liquid/gas mixture goes through the dryer2_bing.gif back to the compressor suction.

There will be about a 1" nut on the low pressure line between the firewall and the compressor. Remove nut and on the male side use a pair of kneedle nose pliers and remove orifice tube. Note orientation of tube.

Replace tube, reassemble, evacuate air from system, recharge with freon.

Im trying to find my low port for the ac unit..where would it be located?


on the tube between the firewall and the a/c compressor. On some Fords the low pressure port is on the dryer (aluminium cylinder). Good news is the low pressure and high pressure port are different sizes. You cannot mess it up.

Location of the oricie tube


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 ,
Wyr

Orifice Tube - 2002 Buick Century


Some are in the inlet to the evaporator and some could be in the condenser line. You can get a new orifice tube on autozone for $5 - 20
