• Q: How to Replace an A/C Accumulator (C60) on 2002 GMC Savana 3500?

  A: The first step to replace the A/C Accumulator requires recovering all refrigerant materials from the system. First remove the engine Coolant Reservoir followed by the air cleaner before removing the grille unit. The evaporator tube detachment process requires disconnecting it from the vehicle while maintaining the nuts and ferrules position on the evaporator tube. You need to detach the nuts on the A/C Accumulator before extracting the A/C Accumulator from its position on the evaporator tube. Place 525 viscosity refrigerant oil onto the o-rings prior to installation on the evaporator tube. After positioning the flow arrow of the A/C Accumulator towards the evaporator place it on the evaporator tube before fastening nuts to 15 n.m (11 lb ft). After reinstalling the evaporator tube professionals need to recharge the a/c system then perform a leak test at the repaired components' fittings by using the halogen leak detector (J 39400-A). The final step includes putting back the grille and engine Coolant Reservoir followed by the air cleaner.
