COOLING SYSTEM [SKYACTIV-D 1.5]

id0112q2002800

Outline

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

• By adopting a water jacket spacer in the water jacket of the cylinder block, the flow speed of the engine coolant near the liner is reduced and heat loss of engine coolant from around the combustion is reduced.
