How to Ensure Proper Installation of an A/C Orifice Tube on Chevrolet Malibu?

First recover the refrigerant while raising the vehicle before beginning to replace the A/C Orifice Tube. The evaporator hose assembly on the condenser requires unfastening its bolt for removal before discarding its seal washer. Immediately apply a tape or cap to prevent contamination of the open condenser line. An A/C Orifice Tube remover tool known as j 26549-e needs to be used for tube extraction. Apply heat near the dimples of the inlet pipe with a heat gun 7 mm (1/4 in) away to loosen a restricted A/C Orifice Tube while using pliers to hold it and performing push-pull motion. Clean the residue before loosening. Thoroughly clean the evaporator inlet line interior to eliminate any kind of contamination. Check the A/C Orifice Tube for damages by inspecting its plastic frame and filter screen (1,2) for tears and plugging and its brass tube for damage. The filter screen can be reused after cleaning with low-pressure shop air when it shows satisfactory cleaning results. The A/C Orifice Tube can be reused if a fresh o-ring is installed with mineral base 525 viscosity refrigerant oil applied to it. Insert the A/C Orifice Tube remover (J 26549-E) into the evaporator line from the short filter screen outlet side with caution when removing the cap or tape. Before installation replace the tape or cap from the condenser line then clean both fittings with a lint-free cloth before adding a new seal washer to the tube. Replace the evaporator hose assembly to the condenser and secure the bolt at 25 n.m (18 lb ft). The vehicle must then be lowered while system evacuation and charging follows before performing a halogen leak detection test on fitting connections (J 39400-A).
