ABSTRACT:
A coolant filter assembly for use in automotive cooling systems includes a filter cartridge having a perforated cartridge shell open at one end to admit coolant and filled with filter material to cleanse the coolant as it passes therethrough, the filter cartridge being removably mounted in an enlarged portion of the coolant path to the radiator inlet, thereby permitting coolant flow both through and around the filter cartridge. Perforations of the cartridge shell include openings in the end wall and openings in the cylindrical sidewall formed at an acute angle to enhance flow through the filter cartridge. Liners of fine filter material are located adjacent the inside wall of the cartridge shell, coarse fibrous filter material is provided in the central portion and magnetized particles are preferably deployed in the fibrous filter material. A filter cartridge housing is provided in two telescopically joined housing halves with the filter cartridge removably mounted therein. Each of the housing halves has an end connector tube for attaching the filter housing in the coolant flow path to the radiator inlet. Alternatively, the radiator inlet itself is enlarged and the filter cartridge mounted in the radiator inlet on a spider member permitting flow around the filter cartridge. The radiator inlet hose is provided with an enlarged end which fits over the enlarged radiator inlet and accommodates the filter cartridge.
