With coolant control valve

Outline

•  The coolant control valve adjusts the coolant control valve opening angle and supplies engine coolant to the appropriate engine coolant passage according to the changes in the engine coolant temperature.

•  Further engine warming has been promoted by blocking each water passage while the engine is cool.

Construction

•  The coolant control valve is located on the left side of the engine.

•  The coolant control valve feeds engine coolant via 3 engine coolant passages.

Note

•  The thermostat is integrated with the coolant control valve. When the engine coolant temperature exceeds the specification, engine coolant is forced to flow into the radiator.

•  Engine coolant flows constantly in coolant passage (1).

•  At coolant passages (2) and (3), engine coolant flows when the rotor rotates and the rotor opening is aligned to each engine coolant passage outlet.

•  The PCM adjusts the coolant control valve opening angle and switches the engine coolant passage according to changes in the engine coolant temperature. For details, refer to the [WATER FLOW CONTROL]. (See WATER FLOW CONTROL [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)
