What is a car heating system?
The heating system in the car is an essential part of the cooling system, as the cooling system has two main functions in every car, the first function is to cool the engine and withdraw heat from it so that it works within the operating temperature efficiently and to provide the best performance.
The second function is to heat and warm the interior of the car during low temperatures to keep the driver and passengers comfortable and keep them warm at all times, especially on days when the cold is severe and the air temperature is very low.
The heating system works with the cooling system permanently and is activated when the car's cabin needs to be heated, and it derives its heat from the heat that the coolant draws from the engine, as the coolant heat is the primary generator of heat for the heating system.
Since winter is just around the corner, it is necessary to choose a car in which the heating system works without issues, and for this, Motorgy offers you used cars for sale in Kuwait inspected by experts for all systems, including the heating system to be happy while driving your future car in the cold weather.

How does the car's heating system work?
The heating system in your car is directly connected to the cooling system, it is an integral part of it, it uses the heat of the coolant that has become hot due to the engine heat to heat the cabin, and the system contains a radiator or thermal heater called the Heater core integrated within the heating system, usually under the dashboard in front of the front passenger and is hidden.
When the heating system is turned on, the hot coolant enters the heating system, specifically the heater core, by pushing it in through the water pump, and after it enters the heater core, the thermostat closes to keep the hot coolant inside the engine and inside the heater to supply it with hot liquid that will turn into air that is pumped into the cabin.
When the coolant gets too hot inside the engine and heater core, the thermostat opens and allows the very hot fluid to exit the engine and heater to go to the radiator to be cooled and returned to the engine and heating system.

When the coolant heats up inside the engine and enters the heater core, the fan of the heating system starts blowing air on the heater, which will turn the cold air into hot due to the passage of air between its fins, which are similar to the fins of the car's main radiator, and then the hot air exits through the vents into the cabin.
The driver can choose the power of the fan as well as the temperature of the air that will enter the cabin according to the nature of the weather, and it is distributed inside the cabin according to the areas chosen by the driver, either on the windshield or on the face of the driver and passenger or on the legs in the front and back.
The heating system depends on the work of the engine as a heating system, as the engine needs to be running in order for the pump to circulate the coolant inside the system and inside the heater core, in addition to that the coolant must be hot to be able to generate heat for the cabin.

If the coolant is cold, especially when you start the engine in the early morning hours, the heating system will not work no matter how hard you try until several minutes later when the coolant heats up due to the heat generated by the engine, which it will take to the heater core to start blowing hot air into the cabin.
The colder the outside temperature, the longer it takes for the engine to heat up and the coolant that the heater needs to heat the cabin. If you notice that the heating system is not blowing hot enough air or is taking a long time to blow air, there may be an issue with the heater or the system in general.
