2002 Chevrolet Impala Parts Questions & Experts Answers

• Q: How to replace the A/C Accumulator on 2002 Chevrolet Impala?

  A: First recover the refrigerant before a replacement of the A/C Accumulator. Installation of the air cleaner assembly happens after you take out the left front fender upper diagonal brace. The A/C Accumulator flare nuts must be loosened before capping or taping the open front evaporator tube and condenser tubes to stop any form of contamination. Extract the A/C Accumulator which is fastened to the evaporator tube then throw away the o-ring. Install new o-rings to the ends of the evaporator tubes following cap or tape removal and perform lubrication steps. Proper installation of the A/C Accumulator to ferrules requires complete seating because it ensures the o-ring properly seats inside the accumulator housing. The A/C Accumulator installation on the evaporator tube must face the evaporator direction while making sure flare nuts reach the 15 n.m (11 lb ft) torque value. The air cleaner assembly must be reattached with the left front fender upper diagonal bracket as well. The last step includes evacuation and recharging of the a/c system followed by halogen leak detector (J 39400-A) testing the component fittings.
