How to replace the A/C Expansion Valve in the auxiliary system on 2001 GMC Savana 3500?

Begin the thermal expansion valve replacement in the auxiliary system by removing the Evaporator core followed by a gentle seal removal procedure around the txv where the mounting position and tube orientation on the core need to be noted. After you remove the capillary tube clip from the Evaporator core you must disconnect txv connections from the Evaporator tubes before taking out the txv from the core. When installing the txv position it onto the core before connecting the Evaporator tubes to the valve with torques set to 28 n.m (21 lb ft). The clip will secure the capillary tube to the Evaporator core before the pack sealer application enables a wrapping of the txv just as in disassembly steps and completion of Evaporator core reinstallation.
