Abstract
The present invention is an apparatus and method for treating coolant for an internal combustion engine. A pump circulates the coolant from an internal combustion engine through a filter and returns the coolant to the internal combustion engine. After circulation, the coolant is delivered to a holding reservoir. Additives and other materials are delivered to an addition reservoir. A vacuum pump is connected to the internal combustion engine to reduce the vacuum air pressure within the cooling system to between 15 and 27 inches of mercury below atmospheric. The addition reservoir and holding reservoir are connected to the cooling system so that the material from the addition reservoir and from the holding reservoir are pulled into the cooling system because of the reduced pressure.
