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

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 Suburban A/C Orifice Tube

Chevrolet Suburban A/C Orifice Tube is the one that maintains balance of refrigerant flow between a high pressure discharge and low pressure suction sides. This allows cabin air to chill quickly on summer drives. The A/C Orifice Tube is applied to force liquid refrigerant through a narrow passage that drops its pressure and forces the compressor to cycle to ensure that the evaporator will absorb heat instead of icing over. If the tube becomes clogged with debris or its calibration becomes inaccurate, a Chevrolet driver will notice temperature swings between cruising and idling. The evaporator may even freeze, warning that it needs to be replaced. Unlike the adjustable expansion valve, which has moving parts and a temperature sensor, the A/C Orifice Tube is a simple fixed insert in a Y shaped junction between the condenser and front evaporator where it also traps dirt. Every Suburban uses this straightforward design, so diagnosis focuses on checking pressure gauges and looking for frost on lines instead of hunting for complex electronics. Cleaning a grimy A/C Orifice Tube involves removing the liquid line, extracting the fragile screen insert with a pair of pliers, washing or swapping the screen insert, and resealing the hose before recharging the system. Timely care keeps the Chevrolet climate system smooth, providing Suburban passengers with reliable cool air and avoiding costly compressor seizures that result from a neglected A/C Orifice Tube.

Each OEM Chevrolet Suburban 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.

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.
