ABSTRACT:
A simple, low cost, replaceable coolant filtering is integrated in a coolant reservoir bottle or reservoir tank of an internal engine liquid cooling system. The coolant filtering system intercepts coolant flowing between the engine cooling system and the coolant reservoir, removing particulates from the coolant by filtration, entrapping the removed particulates on the filter media as well as capturing larger particulates into a drainable cup-like depression provided within the coolant reservoir. Also a coolant bypass passage is operative to permit coolant to bypass the filter should the filter media become blocked with contaminants.
