Abstract
A method for cleaning and protecting a diesel cooling system from corrosion and the effects of the corrosive by-products wherein a filter is used to feed a dissolvable pellet comprising dissolvable cleaning agents and corrosion inhibiting agents into the cooling system. The cleaner consists of chelating agents, surfactants, and anti-foaming agents. The filter is removably inserted in the cooling system, and the cleaners and inhibitors dissolve in the coolant to clean and protectively coat the cooling system while the engine is operating. The removed impurities are captured by the filter and the filter is replaced within a few weeks with a standard filter containing inhibiting agents. The method thus does not require draining the cooling system to clean the cooling system.
