2007 Buick Rainier Parts Questions & Experts Answers

• Q: How to replace the A/C Accumulator on 2007 Buick Rainier?

  A: The first step before installing a new accumulator requires recovery of the refrigerant. Start by disconnecting the electrical connector from the a-c pressure switch followed by removing the a-c low pressure switch. Start by removing the accumulator clamp's nut before unclipping the accumulator from the Evaporator and separating the compressor suction hose assembly from the accumulator's body. The accumulator must be thoroughly cleaned of its o-ring seals so you can remove it from the vehicle along with its clamp nut. During installation apply refrigerant oil to the new accumulator unit. Secure the accumulator within the accumulator clamp before hexing the accumulator clamp nut to 10 n.m (88 lb in). Start by installing the a-c low pressure switch then tighten it to 5 n.m (44 lb in). New o-ring seals should be installed afterward. Fasten the accumulator to the Evaporator using its retaining nut while torqueing it to 28 n.m (21 lb ft). Secure the suction hose to the accumulator before tightening the hose nut so it reaches 48 n.m (35 lb ft). The final task includes circuit connections to the a-c low pressure switch then performs system evaporation while. Verification occurs with j39400-a.
