ABSTRACT:
A spin-on filter assembly for filtering engine coolant has a transparent plastic container attached to a cover plate by an annular joint. The annular joint is formed by an annular trough in the cover plate, which annular trough has a lip which overlies a radial flange on the transparent plastic container. A filter element is disposed within the container and is urged by a coil spring against an end plate which abuts the cover plate. The end plate has a threaded central outlet opening and a plurality of spaced inlet openings which are accessed through a recess in the cover plate. The spin-on filter assembly is mounted in the coolant system of an internal combustion engine by a hollow threaded stud.
