  Q: How to replace the A/C Accumulator on Buick Rendezvous?

  A: Following refrigerant recovery from the a/c system you should raise the vehicle while providing support before removing the A/C Accumulator. Detach the bolts which secure the radiator air deflector and remove the deflector piece. Before loosening the A/C Accumulator flare nuts you should tape or cap the open Evaporator inlet tubes immediately to stop contamination. Dominating the reusable A/C Accumulator from its position on the Evaporator tube marks the beginning of discarding the surrounding o-rings. The technician should first undo the caps or tape from the Evaporator inlet tubes before adding lubrication and installing new o-rings on both ends of each tube. The o-rings must achieve complete seating within the accumulator housing when you fully install the A/C Accumulator to its ferrules. Install the A/C Accumulator into the Evaporator inlet tube while aligning its arrow toward the Evaporator and fasten flare nuts to 15 n.m (11 lb ft). Screw back the radiator air deflector while fastening its bolts at 20 n.m (15 lb ft). Lower the vehicle while performing an evacuating and recharging procedure of the a/c system. Your final step should be leak testing the fittings of the component by using halogen leak detector (J 39400-A).
