• Q: How to replace the A/C Accumulator on 2001 Buick Regal?

  A: The first step when replacing the A/C Accumulator is to recoup the refrigerant. Phase one demands removal of the left front fender upper diagonal brace followed by air cleaner assembly installation. You should loose the A/C Accumulator flare nuts after applying caps or tape to seal the open front evaporator tube combined with the condenser to stop contamination. The A/C Accumulator needs removal from the evaporator tube before discarding its o-ring. Move the tape or cap from the evaporator tubes while adding lubrication to the ends before placing new o-rings on each tube termination. The successful operation of the A/C Accumulator demands proper insertion of the accumulator into its ferrules to achieve o-ring sealing within the accumulator housing. The A/C Accumulator requires installation on the evaporator tube with arrow pointing to the evaporator while tightening flare nuts to 15 n.m (11 lb ft). After replacing these components the air cleaner assembly along with the left front fender upper diagonal brace needs to be restored. The a/c system evacuation follows with recharging then fittings need halogen leak detector (J 39400-A) testing before completing the maintenance work.
