Abstract
An active de-aeration system includes a fill tube, a removable pressure cap, a de-aeration baffle within the fill tube and an externally disposed outlet conduit connected to a sump chamber of the fill tube disposed outside a baffled chamber defined by the de-aeration baffle. The outlet conduit is connected to the coolant system downstream with respect to the fill tube. Air bubbles are actively drawn into the fill tube by coolant movement into the baffled chamber and removably mix with air above a coolant surface in the fill tube.
