Heater Core

The service of heater core begins with removing the heater/vent assembly. Begin by removing the heater core cover screws before taking out the heater core and heater core cover one after another. Install the new heater core by setting it into correct position before putting back the heater core cover. When installing the heater core cover screws users must follow the Fastener Notice in Service Precautions before securing them to 1.6 Nm (14 lb in). Finally, reinstall the heater/vent module.

The replacement process for the auxiliary heater core begins with removing the auxiliary HVAC module and then removing the air temperature actuator from the module. The stud found underneath the auxiliary HVAC module between heater core pipes should be taken out so technicians can separate the gasket and remove the heater core pipe retainer. Start by extracting the auxiliary HVAC module lower cover and subsequently remove the heater core clamp before taking out the heater core from the module. You should start by inserting the heater core into the auxiliary HVAC module before tightening it with the heater core clamp during installation. Install the heater core pipe retainer followed by its gasket before you can attach the auxiliary HVAC module lower cover. Reinstall the stud which connects the heater core inlet to outlet at the underpart of the rear HVAC module. Follow this step by fixing the air temperature actuator onto the auxiliary HVAC module.

The replacement of the heater core inside the auxiliary HVAC module requires the module to be extracted first then the air temperature actuator and heater core cover should be removed. Start heater core removal by taking it out from the auxiliary HVAC module. Begin heater core installation by placing the new component into the auxiliary HVAC module and then return the heater core cover and the air temperature actuator to attach onto the module. The installation of the vehicle's auxiliary HVAC module assembly requires its return it back into the vehicle after all other steps are completed.

The heater core replacement (HEAT ONLY) starts with uninstalling the heater/vent module then proceeding to remove heater core cover screws before uninstalling the heater core cover. Follow the fastening guidance in Service Precautions when you install the new heater core because the next step is to put on the heater core cover followed by the replacement of the heater core. Reinstall the heater/vent module after tightening the heater core cover screws to 1.6 N.m (14 lb in).

The replacement process of Visteon heater cores starts with the HVAC module assembly removal. The first step involves removing the screws holding the heater core cover before extracting the heater core cover out of the HVAC module assembly . The next step requires removing the heater core cowl gasket from the heater core which allows the heater core to be extracted from the HVAC module assembly. Reinstall the heater core inside the HVAC module assembly before putting on the heater core cowl gasket to the HVAC module assembly . Post-installation verify that all hardware is tightly fastened to 2 N.m (18 lb in). Secure the heater core cover onto the HVAC module assembly while maintaining proper tightenness of screws at 2 N.m (18 lb in). Repair the procedure by reinstalling the HVAC module assembly.

Installments for a new Visteon heater core should begin by removing the HVAC module assembly. Screws from the heater core cover must be extracted before pulling the heater core cover apart from its position on the HVAC module assembly. The separate procedure involves removing the heater core from the assembly through the removal of the heater core cowl gasket . Installation begins by putting the heater core inside the HVAC module assembly before installing the heater core cowl gasket to the HVAC module assembly. Install the heater core cover to the HVAC module assembly following the specified instructions in the Service Precautions for Fastener Notice. You should install and tighten the heater core cover screws to 2 Nm (18 lb in). You must reinstall the HVAC module assembly as the last step.

The replacement of the Delphi-based heater core starts with removing the HVAC module assembly. Press the screws from the heater core cover before you take the heater core cover out of the HVAC module assembly. The heater core cowl gasket must be detached from the heater core before the core can be extracted from the HVAC module assembly. Put the heater core into the HVAC module assembly first and then position the heater core cowl gasket on top of the heater core. Use the HVAC module assembly as a base to install the heater core cover before securing its screws which must be tightened to 2 N.m (18 lb in). Put the HVAC module assembly back into position as the last step.

The replacement process for the heater core (Delphi) starts with HVAC module assembly removal. The following steps require separate screw removal from the heater core cover before removing it from the HVAC module assembly. You should then disconnect the heater core cowl gasket from the heater core and remove the heater core from the HVAC module assembly. Put the heater core into position first in the HVAC module assembly before setting the heater core cowl gasket onto the heater core . Reinstall the heater core cover onto the HVAC module assembly before securing its screws at 2 N.m (18 lb in) torque range. The HVAC module assembly should be installed as the last step.

The process of changing the auxiliary heater core begins with the removal of the auxiliary HVAC module followed by unattachment of the air temperature actuator connecting to the module. First access the stud beneath the auxiliary HVAC module while between the heater core inlet and outlet pipes before gently removing the heater core pipe gasket from the module case to take out the heater core pipe retainer. Begin heater core replacement by first removing the auxiliary HVAC module lower cover after you detach the heater core clamp before pulling out the heater core from the auxiliary HVAC module. When installing the core place it inside the auxiliary HVAC module then fasten it with heater core clamp. Insert the auxiliary HVAC module lower cover before installing the heater core pipe retainer along with its gasket. The installation of the stud between heater core inlet and outlet should take place under the rear HVAC module while reattaching the air temperature actuator to the auxiliary HVAC module followed by installation of the auxiliary HVAC module assembly back in the vehicle.
