Abstract
A liquid cooling system having a combined coolant pump/electric motor assembly detached from a liquid cooled internal combustion engine. Liquid coolant is circulated from a radiator, first through the engine head jacket, then through the engine block jacket and back into the radiator. A two-speed electric pump varies the liquid coolant flow rate in relation to a deviation between actual engine temperature and an optimum temperature. The combined coolant pump/electric motor assembly further combines a magnetic clutch with the electric motor such that a separate magnetic clutch is not required.
