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.

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