What causes my car to overheat is a great question To answer the question why does my car overheat we need to understand the components that make up the cooling system. The major players are the radiator, water pump, thermostat, fan, and hoses. The radiator is a heat ex-changer that coolant runs through. Small tubes with fins carry the coolant where the heat is exchanged into the air. The water pump moves the coolant from the engine block where it absorbs heat to the radiator where the heat is removed by the radiator. The thermostat has two roles, to slow the flow down and to regulate the temperature. If the coolant runs through the system too fast it cannot adequately transfer the heat to the coolant. The temperature of an engine has an effect on the efficiency of the engine. Most gasoline engines today prefer to run around 190 to 212 degrees. This makes them run strongest and most fuel efficient. The fan can be driven by belt or electric motor. It pulls air through the radiator to co ... read more
