A coolant filter kit, for attaching in-line to a coolant hose of a combustion engine, includes a fluid conduit member and a coolant filter apparatus. The fluid conduit member has a stem and two opposed branches connected to the stem, with an inlet formed in a first branch thereof, and an outlet formed in a second branch. The fluid conduit member further has a partition in the stem thereof, substantially separating a first flow chamber from a second flow chamber therewithin. In a preferred embodiment of the invention, a limited amount of fluid is allowed to flow directly from the inlet to the outlet without passing through the filter apparatus. The filter apparatus includes a hollow housing defining a filter chamber therein. A porous cylindrical filter element is disposed in the filter chamber of the housing. Optionally, the filter apparatus may include a slow-dissolving tablet or plug for releasing a supplemental coolant additive into coolant over time.

[ What is claimed is:] [1.]1. A coolant filter kit for attaching to an engine coolant hose, comprising:(a) a fluid conduit member having a stem, said stem including means for attaching a coolant filter apparatus, and two opposed branches connected to said stem,(1) said fluid conduit member having an inlet formed in a first of said branches and an outlet formed in a second of said branches;(2) said stem of said fluid conduit member further having a cylindrical sleeve coaxially disposed within said stem, said sleeve defining an intermediate zone therearound within said stem, said sleeve further defining an internal zone therewithin that functions as an outlet flow passage in communication with said outlet, and a wall disposed in said intermediate zone and being integrally formed with said sleeve and said stem, said wall dividing said intermediate zone into a first portion that that functions as an inlet flow passage within the stem in communication with said inlet and a second portion that functions as a bypass flow passage in communication with said outlet, said wall providing for fluid communication through or around the wall from said first portion to said second portion such that fluid bypass around said coolant filter apparatus is provided; and(b) a coolant filter apparatus for attaching to said stem of said fluid conduit member, said filter apparatus comprising:(1) a hollow housing defining a filter chamber therein, said housing having means for interconnecting said coolant filter apparatus to said stem of said fluid conduit member;(2) a hollow outlet tube disposed in said filter chamber, adapted for communication with said outlet flow passage and connected to an end wall of said housing, said housing further having a plurality of inlet holes, adapted for communication with said inlet flow passage, formed therein outside of said outlet tube; and(3) a filter member disposed in said housing and comprising a porous filter element having a hollow bore formed centrally therein, said filter apparatus being constructed and arranged so that said hollow bore of said filter element is in communication with said housing outlet tube.
