When your car's heater is on, hot coolant from the engine is diverted to the heater core to provide warmth to the cabin. If the engine is overheating, it could indicate issues such as low coolant levels, a malfunctioning thermostat, or a failing water pump. These conditions can prevent the cooling system from effectively regulating engine temperature, causing the engine to overheat even when the heater is active. Additionally, if the heater core becomes clogged, it can restrict coolant flow and exacerbate overheating.
