• Q: How to replace the A/C Accumulator on 2009 GMC Savana 1500?

  A: Before changing the air conditioning accumulator use equipment to collect the refrigerant from the a/c system. The process begins with reservoir removal followed by the a/c low pressure sensor electrical connector disconnection before removing the accumulator's evaporator outlet pipe retaining nut. Start by removing the retaining nut securing the compressor suction hose to the accumulator after which disconnect the hose from the accumulator. Next remove the retaining screw securing the accumulator to its bracket before you can detach the accumulator itself. When changing the accumulator you should introduce pag oil according to specifications directly within the accumulator. Follow these steps for installing your accumulator: fit the screw into the accumulator retaining bracket while applying 9 nm (80 lb in) of torque. After plugging in the low pressure sensor connector, install new sealing washers then reinstall the evaporator outlet pipe. Begin installation of the compressor suction hose and its retaining nut which should be tightened to 16 nm (12 lb ft). Next step is the evaporator outlet pipe retaining nut where a torque reading of 16 nm (12 lb ft) applies. The Coolant Reservoir must be installed after the a/c system evacuates followed by recharge operations and further component fitting leak tests using j 39400-a halogen leak detector equipment.
