We are dealing in harvester radiator which function as the main part of the vehicle's cooling system. It has been made to fulfill the purpose of keeping the engine coolant fluid at a desired level. The said coolant flows throughout the engine so as to keep the engine components protected from overheating. It can cool down the fluid as it moves over them. Harvester radiator runs through the main working principle of convection in which a motor car works, very effectively. Convection is the main process through which the heat transfer takes place.
