• Q: How to replace the air conditioning evaporator core on 2008 Chevrolet Express 2500?

  A: The first step in replacing an air conditioning Evaporator core demands the recovery of the refrigerant from the a/c system. You need to detach the low pressure sensor electrical connector as well as the Blower Motor assembly electrical connector and the Blower Motor resistor assembly electrical connector before removing the coolant recovery reservoir. Start by removing the retaining nut from the Evaporator inlet tube then proceed to remove both the Evaporator inlet tube retaining screw and finally take out the tube together with its o-ring seal. Start by taking out the retaining nut from the accumulator after which you should remove the accumulator along with its o-ring seal. Work to disconnect the blower module assembly screws and the blower module assembly components. The last step of this procedure requires removal of the Evaporator core from within the Evaporator and blower module assembly. To replace the Evaporator core you should add pag oil as per specification into the Evaporator unit. Mount the new Evaporator and then put on the Evaporator and blower module assembly and fasten it using retaining screws. Use new o-ring seals to join the accumulator to the Evaporator and fasten it with a retaining nut stirred to 18 n.m (13 lb ft). Begin by fitting the Evaporator inlet tube to its place on the Evaporator then fasten it with a retaining nut that reaches 16 n.m (12 lb ft) before installing the Evaporator inlet tube retaining screw. Connect the electrical wire of the Blower Motor resistor assembly and of the Blower Motor assembly along with the electrical wire of the low pressure sensor assembly. Place the coolant recovery reservoir back then proceed to vacuum and charge the a/c system. Complete the leak test procedure on the components' fittings by using the halogen leak detector (J 39400-A).
