Suzuki heater core is a smaller version of the radiator. Technically, the heater core is not part of the vehicle cooling system. It is more precisely can be considered as component of the vehicle climate control system. If the air conditioning unit lowers the temperature inside the vehicle living compartment, the heater core does the opposite role. It rises the internal temperature of the vehicle. Both the heater core and the air conditioning system maintain a comfortable level of temperature inside the car. When the temperature outside is too humid and hot, the air conditioning system cools down the internal climate of the vehicle. On the other hand, the heater core warms the internal climate of the vehicle if the temperature outside is too cold.

The Suzuki heater core operates in the same manner as the radiator of the vehicle. Coolant circulates from the engine block to the heater core. An electric fan blows air on the heater core. The heater core can be located on the dashboard of your vehicle. If you want to circulate warm air inside your vehicle, you simply turn on the blower (electric fan) that blows air on the heater core. The flow of hot coolant from the engine block can also be controlled by closing the heater valves. A separate water pump allows the circulation of coolant into the heater core.

You can also disengage the clutch of the heater core water pump to stop the circulation of hot coolant into the heater core. This will effectively turn off the heater core. Aside from size and function, another difference between the heater core and the engine radiator is the thermostat. Thermostats are generally not present in heater cores. You should manually switch off the heater core to stop its operation. On the other hand, radiators have thermostats that automatically close valves when the temperature in the engine starts to drop. Only a small amount of thermal energy is derived from the engine by the heater core. Hence, it does not significantly affect the temperature balance of the engine.

Although there are other types of heaters, the heater core is still the most cost-effective and practical. For instance, an air condition unit can double as heater by simply reversing its operation; but it is not practical because it consumes more energy, requiring the engine to work harder. A heater core is also much simpler in design. Air conditioning units are more complex. An air condition unit requires higher voltage of electricity for its compressor and blower fan. If the heater core of your vehicle becomes clogged or defective, it is better to replace it than try fixing it.
