Cooling System Description
Outline
The coolant system uses a liquid cooling pressure circulation type, which is a bottom bypass system with a thermostat located at the water inlet side.

Cooling Control Spacer
By inserting a resin spacer into the the water jacket of the cylinder block, the coolant flow is distributed to the areas with higher cylinder bore temperatures. The effect is the areas with lower cylinder bore temperatures are heated the same as the higher bore temperature areas. This equalization of the coolant temperature around the cylinder walls reduces friction resulting in improved fuel efficiency.
