ABSTRACT:
A coolant filter assembly for attachment to a coolant circulation system of a motor or to a motor housing is provided. The filter assembly includes a housing that accommodates a cylindrical filter cartridge. The housing is sealably connected to the coolant circulation system. The filter cartridge accommodates a sealed chamber between the two opposing ends of the filter cartridge and the inner surface of the filter cartridge. The sealed chamber may be comprised of a continuous sealing layer. As the housing is attached to the coolant circulation system, the sealing layer is punctured or otherwise broken to release liquid coolant additive to the coolant circulation system.
