COOLING SYSTEM [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)]

id0112m1002800

Outline

• Passing water resistance is reduced by improvement of the engine coolant passage shape.

• Pump efficiency has been improved by changing the water pump impeller to a closed impeller.

• A coolant control valve has been adopted to improve fuel economy during low engine loads. (with coolant control valve)
