1.5L L4 Turbo Engine
2.0L L4 Turbo Engine
1. Engine Cooling Fan (Out of View)
2. Coolant Surge Tank and Pressure Cap
Warning
An underhood electric fan 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
Do not touch heater or radiator hoses,
or other engine parts. They can be very
hot and can burn you. Do not run the
engine if there is a leak; all coolant could
leak out. That could cause an engine fire
and can burn you. Fix any leak before
driving the vehicle.
Engine Coolant
The cooling system in the vehicle is filled
with DEX-COOL engine coolant mixture. See
Recommended Fluids and Lubricants 0 311
and
Maintenance Schedule 0 303.
Vehicle Care
The following explains the cooling system
and how to check and add coolant when it
is low. If there is a problem with engine
overheating, see Engine Overheating 0 241.
What to Use
Warning
Plain water, or other liquids such as
alcohol, can boil before the proper
coolant mixture will. With plain water or
the wrong mixture, the engine could get
too hot but there would not be an
overheat warning. The engine could catch
fire and you or others could be burned.
Use a 50/50 mixture of clean, drinkable
water and DEX-COOL coolant. This mixture:
Gives freezing protection down to 37 °C
( 34 °F), outside temperature.
Gives boiling protection up to 129 °C
(265 °F), engine temperature.
Protects against rust and corrosion.
Will not damage aluminum parts.
Helps keep the proper engine
temperature.
