All modern cars are designed so that their cooling system depends on the heating system that goes to the salon. In order for the interior to heat up as soon as possible, the cooling radiator must turn off in a timely manner, and this is what the thermostat was invented for. When the small circuit heats up to 92 degrees, the thermostat begins to open its valve, thereby increasing the line. When the liquid required for cooling reaches its normal temperature, the valve of the device moves to the closed position. If the owner takes good care of his car and changes the antifreeze in time, the thermostat can work for ten years.

The second point that should alert you is that the stove stops heating up, even if at that moment the engine is running for a long time. This is because the thermostat is open all the time.
