• Q: How to replace the auxiliary evaporator core on 2004 Chevrolet Venture?

  A: Your replacement of the auxiliary Evaporator core starts with collecting the needed equipment that includes the halogen leak detector (J 39400-A). Start your procedure by taking out the auxiliary hvac module assembly and progressing to remove the auxiliary txv line clamp screws then the clamp from the hvac module assembly. After removing the auxiliary txv line block fitting bolt you should disconnect the a/c lines from the auxiliary txv while also eliminating the sealing washers and applying an immediate cap or tape to the open a/c lines as a contamination prevention measure. Removal of the auxiliary txv bolts from the auxiliary Evaporator core lets you extract the txv device and discard both sealing washers. You need to take out the auxiliary temperature actuator screws together with the auxiliary blower motor housing screws before removing the auxiliary hvac module case screws to detach case halves and retrieve the auxiliary Evaporator core from the lower hvac module case. Installation of an auxiliary Evaporator core requires pag oil addition with specified amounts before placing the core inside the lower hvac module case followed by casing half reassembly while tightening the screws to 1.6 n.m (14 lb in). You should now install the auxiliary blower motor housing together with its screws and tighten both pieces to 1.6 n.m (14 lb in). Then attach the auxiliary temperature actuator using screws before tightening all fasteners to 1.6 n.m (14 lb in). New sealing washers must be installed on the auxiliary Evaporator core after auxiliary txv line block fitting gets connected to the core and mounting bolts are tightened to 3.5 n.m (31 lb in). Install new sealing washers on the auxiliary txv line block fitting before connecting it to the auxiliary Evaporator core while fastening the retaining bolt at 11 n.m (97 lb in). After securing mounting bolts at 1.6 n.m (14 lb in) on the auxiliary txv line clamp to the hvac module assembly you should reinstall it and examine fittings with a halogen leak detector (J 39400-A).
