Electric water pump
Coolant heat storage
tank
Coolant flow control
valve
The coolant heat storage tank system
stores hot coolant and feeds it via the
electric water pump automatically to warm
the engine as required. This system helps
generate clean emissions. To confirm the
coolant heat storage system check, the
pump may operate automatically with the
vehicle stopped (in the “IG
−
OFF” mode).
Although the pump may operate and
cause noise while the vehicle is stopped,
this does not indicate a malfunction.
CAUTION
D
The coolant in this tank is hot even
if the engine and radiator are cold.
D
For replacement of the coolant,
contact your Toyota dealer.
D
Do not touch bolts (9 pieces)
painted in yellow.
D
In case the bolts are loosened,
there is a risk of hot coolant com-
ing out from inside the tank.
D
When this has any malfunction, the
surface of this tank gets hot. To
prevent burning yourself, do not
touch the tank.
INFORMATION
D
In such cases as the time of engine
starting and a short trip after the
engine is stopped, the electric water
pump will work for a moment, but
this is no problem.
D
This is for the preparation for good
emission.
