How to replace the Heater Core (Visteon) on GMC Yukon?

The repair of the Visteon heater core begins by removing the HVAC module assembly followed by removing screws from the heater core cover until the assembly becomes loose from the module. The procedure requires removal of the heater core cowl gasket from the heater core so you can extract the heater core out from the HVAC module assembly . The heater core installation requires insertion into the HVAC module assembly first and then addition of the heater core cowl gasket followed by reconnection of the heater core cover to the HVAC module assembly . The repair requires using appropriate fasteners which need to be installed in their exact positions since alternative fasteners must be of the proper part number for intended usage.
