  • The engine cooling system is designed to help the engine maintain a particular operating temperature of between 205° F and 220° F (96°C - 104°C). When the system leaks or has some kind of mechanical failure it will allow the engine to run over the recommended temperature which can cause major engine damage such as:

    The purpose of the Engine Cooling System is to prevent the overheating of your vehicle’s engine. With engine combustion reaching extremely high temperatures, the resulting heat needs to be dissipated. An efficient cooling system is essential to prevent the engine from burning!! Another function of the cooling system is to regulate the temperature inside the passenger compartment, insuring your comfort and that of your passengers.

    Engine Cooling System

  • A water pump moves the engine coolant through the engine cooling system, thus providing the coolant circulation between the radiator and the engine. A water pump is usually installed on the engine cylinder block. It pulls cooled-down coolant from the radiator and pushes it through the passages in the engine cylinder block and the cylinder head and again out of the engine and into the radiator. This helps to keep the engine from overheating. The hot coolant passes through the radiator where it cools down and then returns back.

Mechanical Technology: Engine Cooling System

The thermostat regulates the engine coolant temperature in the engine coolant system. When a thermostat fails, if often gets stuck and fails to regulate the coolant temperature. If the car’s computer doesn’t see the engine coolant temperature rising to the correct operating temperature, it will illuminate the CEL. The solution? Replace the thermostat!
