Abstract
A device for treating and conditioning engine coolant for use with an internal combustion engine includes a housing having an inlet and outlet and a filtering media and container carrying coolant treatment material located within the housing. Coolant passes through the filter, and then is exposed to the tip of a rod which erodes away to permit treatment material to be discharged in the coolant. As the corrosiveness of the coolant decreases, erosion of the rod is discontinued, so that additional treatment material is no longer discharged into the coolant. Accordingly, the corrosiveness of the coolant is controlled to within relatively narrow limits.
