The invention relates to method and apparatus for filtering engine coolant flowing in the cooling system of an automotive internal combustion engine. The method consists of constraining engine coolant which normally discharges from an overflow port in the cooling system radiator to pass through a filter into a reservoir, and of applying the suction normally produced at the overflow port as the cooling system cools to draw the filtered engine coolant back into the cooling system.

In combination with an internal combustion engine cooling system having overflow port means permitting overflow of liquid engine coolant when the cooling system overheats, and providing suction as the cooling system cools, a filtering apparatus comprising: filtering means for removing debris from engine coolant passing through the filtering means, including filter inlet means for receiving engine coolant to be filtered and filter outlet means for releasing filtered engine coolant; a reservoir in fluid communication with the filter outlet means for receiving and containing the filtered engine coolant; conduit means for placing each of the filter inlet means and the interior of the reservoir into fluid communication with the overflow port means to permit flow of engine coolant therebetween; and, valve means for directing the flow of fluids through the conduit means so that in use (a) engine coolant overflowing from the overflow port means is forced through the filter means into the reservoir and, (b) the suction provided at the overflow port means when the cooling system cools draws filtered engine coolant from the reservoir.
