Engine Coolant - Chevrolet 2010 Camaro Owner's Manual

Notice: Using coolant other
®
than DEX-COOL can cause
premature engine, heater core,
or radiator corrosion. In addition,
the engine coolant could require
changing sooner, at 50 000 km
(30,000 miles) or 24 months,
whichever occurs first. Any
repairs would not be covered by
the vehicle warranty. Always use
®
DEX-COOL (silicate-free) coolant
in the vehicle.

Engine Coolant

The cooling system in the vehicle
is filled with DEX-COOL
coolant. This coolant is designed to
remain in the vehicle for five years
or 240 000 km (150,000 miles),
whichever occurs first.
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 on
page 9-24.
What to Use
Adding only plain water to the
cooling system can be dangerous.
Plain water, or some other liquid
such as alcohol, can boil before
the proper coolant mixture will.
The vehicle's coolant warning
system is set for the proper
coolant mixture. With plain water
or the wrong mixture, the engine
could get too hot but you would
not get the overheat warning.

engine
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.

WARNING
®
Vehicle Care
Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
coolant. If using this mixture,
nothing else needs to be added.
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.
Notice: If an improper coolant
mixture is used, the engine could
overheat and be badly damaged.
The repair cost would not be
covered by the vehicle warranty.
Too much water in the mixture
can freeze and crack the engine,
radiator, heater core, and other
parts.
