How do you remove the expansion orifice tube on Chevrolet Express and GMC Savana?

To remove the A/C orifice tube, start by discharging and recovering the refrigerant. Then, open the hood and locate the fitting for the A/C orifice tube. Hold the stationary fitting with one wrench and loosen the other fitting with another wrench. Inside the pipe leading to the evaporator, you will find the orifice tube with a fixed-diameter orifice and mesh filters at each end. Use needle-nose pliers to remove the orifice tube. It is important to check if the screens are not plugged, torn, and if the plastic housing over the screens is intact, as well as ensuring that the brass orifice inside the housing is unrestricted. For installation, insert the A/C orifice tube with the shorter end first towards the evaporator. Reconnect the refrigerant line and tighten the fitting securely. Finally, have the system evacuated, recharged, and leak-tested by a professional shop.
