• Q: How to replace the A/C Orifice Tube on 2005 Chevrolet Cavalier?

  A: Tool requirements for A/C Orifice Tube replacement include Halogen Leak Detector (J 39400-A) and A/C Orifice Tube Remover (J 26549-E). Start the procedure by taking out the evaporator tube alongside its separation from the condenser tube. The removal task requires the A/C Orifice Tube Remover (J 26549-E) to pull out the A/C Orifice Tube. Check the tube for breakage of plastic frame components and examine filter screens for deterioration or blockage (1,2) and brass A/C Orifice Tube condition before performing replacement when necessary. The metal debris on the filter screen can be cleaned using low-pressure shop air until it becomes fit to reuse. The O-ring must receive mineral base 525 viscosity refrigerant oil for light coating before reinstalling it into the tube. After removing tape and caps from the evaporator line, use needle-nose pliers to handle the A/C Orifice Tube edge while avoiding contact with the filter screen, direct the tube into the evaporator with its longer screen section facing outward. Apply minimal 525 viscosity refrigerant oil to both new O-rings before placing them on sealed tube fittings with a lint-free cloth. First reinstall the evaporator tube then evacuate and recharge the A/C system while performing a leak test through the fittings by using the Halogen Leak Detector (J 39400-A). The last step involves integrating the hood close out filler panel.
