2001 Buick Park Avenue A/C Orifice Tube Parts Questions & Experts Answers

• Q: How to replace the A/C Orifice Tube in an A/C system on 2001 Buick Park Avenue?

  A: The refrigerant recovery phase must happen first before starting replacement of the A/C orifice tube. After releasing the evaporator tube from retaining clips you should loosen the tube nut while separating it from the A/C orifice tube area. Proceed with the A/C orifice tube separation from the tine at the next step. Apply mineral base 525 viscosity refrigerant oil to lubricate the O-ring before A/C orifice tube installation which should have the short screen positioned toward the evaporator. Install the A/C evaporator tube while securing both dual O-ring joints at 24 N.m (18 lb ft). Install the evaporator tube to its retainer clips before performing A/C system recharging followed by testing the component fittings with the Halogen Leak Detector (J 39400-A).
