• Q: How to Replace an Evaporator Core in a Visteon System on 2005 Chevrolet Tahoe?

  A: Replacing the Evaporator core (Visteon) demands removal of the hvac module and detachment of the electrical connector from the recirculation actuator. Begin by removing the Evaporator cover screw set then eliminate the cover from the hvac module assembly. First you should remove the Evaporator cowl gasket which is attached to the Evaporator before pulling the Evaporator core out of the hvac module assembly. The installation process requires adding petroleum base oil to the Evaporator core but only when you are also replacing the condenser. The hvac module assembly accepts the Evaporator core while installation of the Evaporator cowl gasket goes on the Evaporator before installing the Evaporator cover onto the hvac module assembly. The correct fasteners need to be installed where they belong because replacement fasteners should match exactly with the specified part number for proper use. Fasteners together with their joint surfaces should always remain free of paints and lubricants and corrosion inhibitors because such substances alter torque and clamping force measurements. When following tightening procedures it is necessary to use the correct sequence and specifications to avoid damaging components. Complete the installation by fastening screws to the Evaporator cover while tightening them to 2 nm (18 lb in) torque then connect the electrical connector to the recirculation actuator before reinstalling the hvac module.
