(2) Overflow pipe

7.10.3 Function of reserve tank

When radiator internal pressure is above specified
pressure
Coolant expanded by high temperature is discharged to
and stored in the reserve tank.
When radiator internal
atmospheric pressure
When the engine cools, the coolant in the reserve tank
returns to the radiator based on lower than atmospheric
pressure.
