The location of the heater core is under the steering system and dashboard. Its components, such as wires, pipes, coolant container and exhaust gases, are located on all sides of the dashboard. The heater core is the main component that controls the heating and cooling functions inside to normalize the atmosphere in the cabin. The heater core adjusts the
coolant in the cooling system to supply warm air to the cabinet and prevent overheating. In addition, the coolant reduces overheating, which causes the windows to mist over.

Foggy windows are also one of the main signs of a bad heater core. If the windows of your car are fogging inside, it means your car faces problems with the heater. This is a sign that the fluid in the radiator is leaking inside the car, which makes it foggy. The fog window function is also called window condensation. Using expert maintenance tips can be a good idea for properly maintaining a car's cooling system.

2. Coolant leak

Another serious sign of damage to the heater core is the leakage of radiator fluid inside and outside the car. It is quite easy to suspect a coolant leak in a car from a seat on the passenger side or spilling coolant to the ground. This happens when the system is colder than usual. Your seats in the front cabin may be wet if there is a leak.

Coolant could also spill from the coolant tank. So repair the whole system as soon as possible.

4. Cooling system failure

If your cooling or heating system is not functioning properly, then it's time to give it service or repair. The absence of heat or heat in the cabin will prove the failure of the cooling system.
