Abstract
A system includes a coolant pump and a first rotary valve. The coolant pump is configured to be mechanically driven by an engine and to send coolant to an inlet of the engine. The first rotary valve is configured to receive coolant from an outlet of the engine and to send coolant to a first radiator and a heater core. The first rotary valve is adjustable to a zero flow position to prevent coolant flow to the first radiator and the heater core and thereby increase a rate at which the engine warms coolant flowing therethrough.
