2003 Chevrolet Venture A/C Expansion Valve Parts Questions & Experts Answers

• Q: How to replace the A/C Expansion Valve in the auxiliary system on 2003 Chevrolet Venture?

  A: The first step for A/C Expansion Valve replacement in the auxiliary system includes refrigerant recovery. Restrain the left lower quarter trim panel along with the foam wrap around the auxiliary A/C Expansion Valve before proceeding. Start by unscrewing the screws on the line clamp of the auxiliary A/C Expansion Valve system then unload the clamp from the hvac module assembly. The bolt behind the auxiliary A/C Expansion Valve line block fitting needs extraction before removing a/c lines from the auxiliary A/C Expansion Valve while discarding sealing washers. Seal the exposed a/c lines right away with tape and caps in order to stop contamination. Detach the bolts fixing the auxiliary A/C Expansion Valve to the Evaporator core before removing it from the core while capping off the Evaporator core lines with tape or alternative sealing before discarding all washers. To install replace the covering from Evaporator lines before fixing new sealing washers to the auxiliary A/C Expansion Valve installation on the Evaporator core by tightening mounting bolts to 3.5 n.m (31 lb in). Take off any caps or tape from the a/c lines then substitute new sealing washers before linking these hoses to the auxiliary A/C Expansion Valve where you should fasten its retaining bolt to 11 n.m (97 lb in). Reinstall the hvac module auxiliary A/C Expansion Valve line clamp and tighten its clamp screw to 1.6 n.m (14 lb in). End your work by putting new foam on the auxiliary A/C Expansion Valve then vacuum the a/c system for recharging. Additionally install the left lower quarter trim panel.
