2003 Chevrolet Astro A/C Accumulator Parts and Q&A

• Q: How to install the A/C Accumulator (ACDelco P/N 15-1697) on 2003 Chevrolet Astro?

  A: You must start the A/C accumulator installation process by taking away the evaporator tube from your vehicle. The project begins by marking 40 mm (1.5 in) from the evap tube bend close to the high side access port then continuing the mark 50.8 mm (2 in) from that first point. Through use of a tubing cutter, trim the evaporator tube at the designated spot while preventing metal burrs from entering the tube both during cutting and removal processes. First remove the burrs from the evaporator tube before untightening nuts and removing O-rings from ferrules at A/C accumulator. Only install the ferrules and nuts onto the evaporator tube pieces without placing the O-rings at this time. Position the A/C accumulator onto the evaporator tube with the flow arrow facing the evaporator while installing ferrules which should have the small end at the nut side. When positioning the evaporator tube inside the A/C accumulator, agent should apply torque on the nuts until they reach 15 N.m (11 lb ft). Prior to installing the O-rings on the evaporator tube apply 525 viscosity refrigerant oil to them. The O-rings need to be placed on the evaporator tube. Secure the nuts on the A/C accumulator and torque them to 15 N.m (11 lb ft). Reinstall the evaporator tube into the vehicle before completing a leak test of the component join(s) with the Halogen Leak Detector model J 39400-A.
