2005 Buick Park Avenue Parts Questions & Experts Answers

• Q: How to replace the A/C Accumulator in a system on 2005 Buick Park Avenue?

  A: Frigerant recovery operations must begin before replacement of the accumulator. Start by removing both the evaporator hose from the accumulator cover and then unscrew the accumulator cover. Start by removing the accumulator's compressor hose nut before separating the hose and throwing away the washer from the compressor hose. Perfect the connection by loosening the accumulator tube nut while you pull away the accumulator tube from its bracket and throw away the o-rings attached to it. Begin by uninstalling the accumulator bracket bolt then remove the accumulator from its bracket position. To set up the accumulator workers need to pour refrigerant oil at the approved level before installing it to the bracket using an accumulator bracket bolt that should be tightened to 6 n.m (53 lb in). Fit the new sealing washer onto the compressor hose after connecting it to the accumulator then tighten the compressor hose nut to 24 n.m (18 lb ft). The work requires new o-rings for the accumulator tube which must be attached to the accumulator and secured using the accumulator tube nut at 24 n.m (18 lb ft). Asiaquate the accumulator cover onto the accumulator while applying pressure for attachment followed by connecting the evaporator hose to the accumulator cover. To finish the repair process you need to both evacuate and recharge the a/c system then conduct a halogen leak detector (J 39400-A) assessment of all a/c component fittings.
