Mercedes S430 Replacement Radiator Information


Although it's nestled out of sight behind the fancy grille work on your Mercedes S430, the radiator is an essential part of your car. Radiators can be complete deal breakers because they help cool the entire engine block. If they fail, your car will continue getting hotter and hotter, losing fuel efficiency in huge steps until it finally overheats and you have to call for a tow.

Radiators are full of pipes or tubes that flow in a convoluted back-and-forth manner. This winding path increases the amount of surface area available for cooling, which is necessary because radiator tubes are filled with the cooling fluid that circulates through your engine block. Your S430 radiator's ability to cool that fluid efficiently relies on the airflow coming through your grille and the contact surfaces of the radiator, which must be designed to allow efficient heat transfer.
