• Q: How to install the A/C Accumulator (ACDelco P/N 15-1697) to the A/C evaporator tube on 2002 Chevrolet Express 2500?

  A: Install A/C Accumulator (ACDelco P/N 15-1697) to the a/c Evaporator tube (liquid line) next to the condenser and Evaporator by first removing the air cleaner, engine Coolant Reservoir, and grille. Before measurement begin by removing the Evaporator tube from the vehicle. Afterward find 60 mm (2.5 in) from the condenser end to make a placement mark. Perform this operation with a tubing cutter at a 50.8 mm (2 in) length from the mark to cut the section of Evaporator tube while ensuring no metal burrs enter the tube during cutting or removal. Place the smooth side of nuts along with ferrules over each half of the Evaporator tube after removing the burrs. Place ferrules onto the Evaporator tube having their small end directed at the nut before attaching the A/C Accumulator with its flow arrow facing the Evaporator. During this operation keep the Evaporator tube inside the A/C Accumulator while tightening nuts to 15 n.m (11 lb ft). Place 525 viscosity refrigerant oil on the o-rings before installing them onto the Evaporator tube. Fasten the A/C Accumulator nuts to 15 n.m (11 lb ft) torque. Last, reinstall the Evaporator tube into the vehicle and recharge the a/c system before using the halogen leak detector (J 39400-A) to check for leaks then you can put back the grille, engine Coolant Reservoir and air cleaner.
