Cooling System; Engine Coolant - Chevrolet Impala 2013 Owner's Manual

Cooling System

The cooling system allows the
engine to maintain the correct
working temperature.
When it is safe to lift the hood:
A. Engine Cooling Fans (Out
of View)
B. Coolant Surge Tank and
Pressure Cap
WARNING
An electric engine cooling fan
under the hood can start up even
when the engine is not running
and can cause injury. Keep
hands, clothing, and tools away
from any underhood electric fan.
WARNING
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the engine if there is a
leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
