The Heater Core in GMC Yukon vehicles has the responsibility of warming up the cabin with the assistance of excessive heat from the engine. Looking like a miniature radiator, this component is cooled with a water and antifreeze solution; hot coolant from the engine flows through the core to warm the air in the cabin. Different control methods, including the valve or door, control the movement of coolants through the core to control climates. Besides, the heater core can also enhance the function of engine cooling as well as dehumidification for air-conditioned automotive vehicles. But normal problems such as blockage and dripping can only worsen the situation leading to regular repairs conferred to the core as the structure has various complex components which need to be removed to access the core.
