Your Mercedes S320 Radiator is one of the main components that make up your cooling system. The radiator essentially works in conjunction with the antifreeze to effectively regulate the temperature in the engine of your luxury vehicle. The antifreeze, sometimes called coolant, flows throughout the engine and cylinder heads in a closed loop that eventually runs through the radiator.

As the antifreeze makes its way through the engine, it pulls heat away from the engine parts, heating itself up in the process. The radiator’s job, in turn, is to cool down the antifreeze.

Situated in the front of your vehicle’s engine, the Mercedes S320 Radiator uses the air that rushes through the grille and an internal fan to properly cool down the antifreeze so it can make another pass through the engine. In order to maintain a constant adequate temperature, there is a temperature-operated valve that sits between the engine and the radiator. This valve will stay closed, blocking the path of the antifreeze, until the temperature of the engine increases to the proper activation point. Once the thermostat on the temperature valve discovers that the engine is getting too hot, it will open to allow the radiator to start cooling the antifreeze. If your radiator becomes jammed or broken, it will likely cause the fan to stop spinning, which will reduce the amount of heat transfer taken away from the coolant. This may eventually lead to your car overheating. To avoid this, an OE quality radiator is a must.With this Mercedes S320 Radiator, you can be sure that your luxury vehicle will stay properly cooled even in the hottest of temperatures.
