• Q: How to replace the A/C Accumulator on 2001 Chevrolet Impala?

  A: The first step for replacing the A/C Accumulator is to recover the refrigerant. The installation of the air cleaner assembly begins after you remove the left front fender upper diagonal brace. Before tightening the A/C Accumulator flare nuts you must instantly close both the evaporator front tube and condenser with tape or caps to avoid contaminants while working. Pull the A/C Accumulator out from its position on the evaporator tube before throwing away the o-ring seal. Place new o-rings on the end points of evaporator tubes before lubricating them. Afterwards replace the protective cap or tape whenever possible. Full installation of the A/C Accumulator against the ferrules must be achieved to properly position the o-ring within the accumulator housing. Secure the A/C Accumulator onto the evaporator tube by turning the flare nuts to 15 n.m (11 lb ft) while aligning the arrow toward the evaporator. The next procedure involves reinstalling both the air cleaner assembly along with the left front fender upper diagonal brace. Evacuation and recharging of the a/c system completes the procedure with a fitting test utilizing the halogen leak detector (J 39400-A).
