    Q:
    How to replace the A/C Orifice Tube on Chevrolet Silverado 1500 Classic? Posted by Customer
    A:
    The first step for replacing the A/C orifice tube involves the recovery of refrigerant. You can uninstall the A/C orifice tube from its position on the evaporator tube by using the Orifice Tube Remover (J 26549-E). Begin this process by first loosening the nut connected to the evaporator tube fitting. Cap or plug the open line. Before O-ring installation on the evaporator tube seek to lubricate it with 525 viscosity refrigerant oil from new supply. Install the replacement A/C orifice tube into the evaporator tube but make sure that the O-ring seal receive application of 525 viscosity refrigerant oil. The long screen side of the new A/C orifice tube must be inserted into the evaporator tube before attaching it at the fitting while maintaining a torque of 25 N.m (18 lb ft). Evacuate the system along with recharging it while conducting a Halogen Leak Detector test on fittings that make up the repaired component (J 39400-A).

    Q:
    How to replace the A/C Orifice Tube on Chevrolet Silverado 3500? Posted by Customer
    A:
    Begin a replacement of the A/C orifice tube by recovering all refrigerant first. You need to loosen the evaporator tube fitting nut before you can take out the A/C orifice tube using the Orifice Tube Remover (J 26549-E). Cap or plug the open line. Installation begins with uncapping the evaporator tube after which you should use new 525 viscosity refrigerant oil to lubricate the new O-ring before fitting it into place. The short screen portion of the new A/C orifice tube needs to receive 525 viscosity refrigerant oil before insertion into the evaporator tube. Install the evaporator tube into its fitting before securing it with 25 N.m of torque (18 lb ft). The system evacuation and recharging process should be followed by fitting leak tests using a Halogen Leak Detector (J 39400-A).
