How to remove and install an A/C orifice tube in an air conditioning system on Chevrolet Tahoe?

To remove the A/C orifice tube from an air conditioning system, the system must first be discharged. The tube is located in the liquid (high-pressure) line near the accumulator and can be removed by holding the stationary fitting with one wrench and loosening the other fitting with another wrench. The tube has a fixed-diameter orifice and a mesh filter at each end, and can be removed with needle-nose pliers. If it is stuck or breaks off, a special tool may be required. The orifice tube meters the refrigerant, changing it from a high-pressure liquid to a low-pressure gas, and can be reused if the screens aren't plugged, torn, or the plastic housing is intact and the brass orifice is unrestricted. To install the A/C orifice tube, insert it with the shorter end pointing toward the evaporator, reconnect the refrigerant line, and have the system evacuated, recharged, and leak-tested.

Chevrolet Tahoe A/C Orifice Tube

The Chevrolet Tahoe A/C Orifice Tube is the exact metering gateway to allow the liquid refrigerant to enter the evaporator while preventing the high-pressure and low-pressure sides of the system from communicating with each other. Unlike the adaptive expansion valve applied by some earlier Chevrolet sport-utes, the A/C Orifice Tube is a fixed calibrated insert and thus regulates flow by forcing the compressor to ramp output or shut off completely whenever pressure differences change. Inside every Tahoe built with this fixed device, the A/C Orifice Tube also acts to strain out moisture-driven gunk and stray metal flakes from the lines, keeping them from lodging deeper in the lines. When age or debris clogs the tiny mesh, refrigerant backs up, pressures swing wildly between highway speeds and idle, cabin vents blow warm or the evaporator can even ice over. Swapping in a fresh A/C Orifice Tube restores steady pressure so the evaporator will absorb heat steadily and cabin temperatures finally reflect the dash setting. For drivers comparing system layouts, it should be remembered that the variable expansion valve uses temperature and a moving pin to trim pressure on the fly, whereas the Chevrolet setup with a fixed A/C Orifice Tube relies on compressor cycling instead, making diagnosis simpler but placing greater importance on tube cleanliness. Keeping your Tahoe A/C chill begins with monitoring this small part before a minor restriction turns into major component failure.

Each OEM Chevrolet Tahoe A/C Orifice Tube we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
