Heater cores are part of the cooling system of the vehicle’s engine. The warm engine coolant flows through the heater core and exchange heat with the air in the vehicle interior to warm up the interior in cool conditions. The interior air is pushed through the heater core by the blower motor. After the air is warmed up it is distributed to the different air outlets, like feet, face or defrost outlets. The air distribution and blower fan speed is either controlled by the driver or passenger or automatically when equipped with a climate control system.
DENSO heater cores are designed alongside experts and manufactured to OE quality standards to ensure optimum HVAC performance journey after journey.
