ABSTRACT:
An engine cooling system is provided that includes an engine, a radiator, and a coolant pump. A thermostat is disposed in a chamber formed in a coolant passageway connecting the radiator and the coolant pump. The thermostat selectively opens and closes the coolant passageway in response to the temperature of coolant flow from a throttle body disposed in another coolant passageway connecting the outlet portion of the engine body and the coolant pump. Preferably, the thermostat is actuated depending only on the temperature of coolant passing through the throttle body.
