Radiator

Engine Cooling Radiator Brazed Cooling Fins. Radiators help regulate your Mercedes engine's temperature and keep it within its optimal operating range. It is made up of two tanks which can be metal or plastic, connected by metal tubes with fins attached to direct air across the tubes called a core. Coolant circulating within the engine absorbs the engine's heat, bringing down the engine's temperature. This hot coolant then flows into one of the radiator's tanks. It is pushed through the core of the radiator, where heat from the coolant is passed to the air flowing through it, reducing the temperature of the coolant before entering back into the engine from the opposite radiator tank.
