A radiator, fan, water pump, coolant reservoir, thermostat, and any required pipes make up a vehicle cooling system. To remove heat from the engine, heat exchange occurs inside the engine. Coolant reservoirs, which contain the coolant liquids, are where the sequence begins. Automotive Radiator resembles the way refrigerant gas moves through the compressor system. Through a water pump, the coolant fluid is circulated throughout the whole engine circuit. The heat produced by the engine is absorbed by the coolant. The heat transfer mechanism states that heat moves from heated to cold surfaces. As a result, the coolant liquid dissipates the heat. The thermostat is a sensor-style device that continuously measures the coolant liquid's temperature. Normally, the thermostat permits the coolant to pass to the Automotive Radiator inlet when the coolant liquid temperature rises over the engine working temperature (200–250 degrees Celsius).
