Radiators and Charge Air Coolers are critical components when it comes to proper engine temperature and combustion air temperature control. Combined with the fan clutches, blades, hoses and clamps also offered by Diesel Components, Inc. they comprise perhaps the most critical system of the engine. Even the fuel and electrical systems don’t work if the engine temperature gets too high or coolant gets into the air stream. From charge air cooler test kits to complete new, vehicle specific, radiator and charge air coolers from companies like Av-Tekk and Northern Factory, Diesel Component’s, Inc has what you need.
