  Q: How to install the A/C Accumulator (ACDelco P/N 15-1696) on GMC Canyon?

  A:

  Start the installation process of the A/C accumulator (ACDelco P/N 15-1696) by conducting leak detection using a Halogen Leak Detector (J 39400-A) to check for any gas emissions. Extract the evaporator tube from the clips located inside the cowl. Apply a mark 50 mm beyond the bend on the evaporator tube adjacent to the driver fender before moving 50.8 mm from that point. Use a tubing cutter to cut along the marked portion of the evaporator tube while making sure metal burrs avoid entering the tube during both cutting and removal processes. Take off the nuts, ferrules, and O-rings from the A/C accumulator before skipping installing the O-rings at this moment. Insert each ferrule along with its nut into the evaporator tube ends so the ferrules maintain the small end facing the nut. The installation of the A/C accumulator must commence with its attachment to the evaporator tube using the flow arrow direction as the reference. When you securely manage the evaporator tube within the accumulator, tighten the nuts using 15 N.m (11 lb ft.) torque. You should start by uninstalling the nuts which secure the accumulator before placing O-rings to the evaporator tube halves. Once installed, reinstall the nuts tightly to 15 N.m (11 lb ft). Evacuation and recharging of the system needs to be followed by a leak test on the fittings utilizing the Halogen Leak Detector (J 39400-A).

  Q: How to replace the A/C Accumulator in an A/C system on GMC Canyon?

  A:

  First remove the refrigerant from the A/C Accumulator before removing its grille. Before touching any hoses or lines ensure the system is completely discharged to prevent r134a from causing harm to the operator. First detach the condenser hose bolt followed by the condenser hose from the A/C Accumulator then remove the evaporator tube bolt together with its tube. A set of caps should be installed onto both the condenser hose and evaporator tube to stop moisture and oil from leaking out. Approach the A/C Accumulator bracket bolts and assembly to remove them and loosen the clamp bolt which enables A/C Accumulator extraction. When installing a fresh A/C Accumulator select the recommended pag oil quantity from the specifications based on the system capacity. Put the A/C Accumulator bottle inside the clamp yet avoid tightening the bolts and replace every o-ring with pag oil for internal circulation while 525 mineral oil must solely be applied to threads and o-rings. Place the A/C Accumulator bracket bolts while tightening the clamp bolt to reach 5 nm (44 lb in). First detach the condenser hose cap together with its plug before installing a fresh seal washer. Attach the evaporator tube along with its bolt and achieve proper engagement at 20 nm (15 lb ft). Then connect the condenser hose with its bolt before securing it at 20 nm (15 lb ft). The process ends with evacuation of the a/c system while recharging it followed by leak testing with j 39400-a tool before returning the grille.
