• Q: How to replace the auxiliary heater core on 2005 Chevrolet Venture?

  A: One must begin the auxiliary heater core replacement process by eliminating the auxiliary HVAC module followed by unscrewing the auxiliary heater pipe clamp screw and mounting screws of the auxiliary heater core. The HVAC module assembly requires separation from the auxiliary heater core before pipe seal and heater core mounting bracket removal from the auxiliary heater core can proceed. New seals should be installed onto the auxiliary heater core followed by attaching the heater core mounting bracket. The HVAC module assembly requires insertion of an updated pipe seal which comes before installing the auxiliary heater core. Always use the proper fasteners which need installation at their designated spots because replacement fasteners require matching the specific part numbers for proper use. The service procedure indicates which fasteners require replacement as well as which ones require thread locking compound or sealant application. Paints along with lubricants and corrosion inhibitors must not be applied to fasteners and their joint areas because these substances can alter torque values and clamping force which causes damage to the fastener. Follow exact tightening order and specifications to protect both parts and systems from harm. The worker should install the auxiliary heater core mounting screws at 1.6 Nm (14 lb in) torque before tightening the auxiliary heater pipe clamp screw to 1.6 Nm (14 lb in) torque. Then replace the auxiliary HVAC module.
