it is located inside the coupler between the high side and low side fittings on the passenger side of the engine compartment
Located in front of the radiator on the passenger side in the condensor line.
I have 1998 chev suburban with rear air do they use two orifice tubes
It does not have an orifice tube.
To replace the orifice tube on a 2001 Chevy Express van, first, ensure the AC system is fully discharged and take necessary safety precautions. Locate the orifice tube, which is typically found in the liquid line between the condenser and the evaporator. Remove the line using the appropriate tools, pull out the old orifice tube, and insert the new one. Finally, reassemble the line, recharge the AC system, and check for proper operation.
Most orifice tubes are placed in the high pressure line to the evaporator at the fire wall connection. You will have to empty the freon from the system to replace the orifice tube which is not very expensive (the tube, that is).
To install the orifice tube in a 2003 Chevrolet Suburban, first ensure the vehicle is off and the AC system is fully discharged. Locate the orifice tube, which is typically found in the liquid line between the condenser and the evaporator. Remove the old orifice tube using pliers or a puller, clean the area, and then insert the new orifice tube, ensuring it is seated properly. Finally, reassemble any components and recharge the AC system.
The orifice tube is built inside the liquid line and can not be serviced separately.
What orifice tube?
location of orfice tube in a 1999 chevy malibu On your 1999 Malibu the expansion (orifice) tube is located at the condenser to evaporator connection in the evaporator tube.
On some suburbans its at the connection behind passenger turn signal.
Yes but, it is called an orifice tube.
If its a single evaporator unit (front air only). then it is probably located in the condensor. If it is a dual unit (front and back), the front orfice tube will probably be after the "Y" in the compressor high pressure line, and prior to the accumulator. The rear unit does not use an orifice, but rather a Thermal expansion valve.
