ABSTRACT:
An engine cooling system and method and apparatus for controlling hydraulic fluid flow between a plurality of hydraulic components in a hydraulic system is shown. The system and method utilized at least one hydraulic sensor for actuating a hydraulic valve which controls the fluid delivery to the hydraulic components. At least one of the hydraulic sensors includes a thermosensitive material which causes the sensor to deliver hydraulic pressure to an actuator on the valve when the material is heated in response to an increase in temperature of, for example, a coolant associated with the engine.
