  Q: How to replace the A/C Expansion Valve for the Auxiliary Air Conditioning Evaporator on GMC Savana 1500?

  A: The replacement process of the auxiliary air conditioning Evaporator A/C Expansion Valve requires removing the Evaporator core first. Unpack the sealer material surrounding the A/C Expansion Valve (TXV) by using gentle force while recording its position on the core regarding the tube orientation. After detaching the clip which holds the capillary tube to the Evaporator core, disconnect the tube connections of the Evaporator from the txv to extract the txv from the core. Installation requires the attachment of the txv to the core with precautions needed for fastener use. The technician installs the Evaporator tube connections to the txv before tightening them to 28 nm (21 lb ft) while applying a clip to hold the capillary tube against the Evaporator core. Seal the txv with pack material following the same procedure that was used during removal and replace the Evaporator core in the system.
