ABSTRACT:
An air filter is described which is used in conjunction with an overflow receptacle or container of an engine cooling system. The container is in fluid communication with the engine cooling system so that coolant may flow from the cooling system to the container when the coolant expands within the cooling system and to permit the coolant to be drawn back inwardly into the cooling system as the coolant cools. The upper end of the container is provided with a fill opening having a threadadly mounted closure element thereon. The closure element is provided with a plurality of openings formed therein to permit air to be drawn into the container as the coolant therein is drawn into the cooling system and to permit air to escape outwardly therethrough when coolant is passing from the cooling system into the container. A filter is positioned over the openings in the closure element together with means for maintaining the same thereon so that the air being drawn into the container will be filtered to remove foreign particles or substances therefrom.
