Caution
Failure to use the recommended
engine oil or equivalent can result
in engine damage not covered by
the vehicle warranty.
Viscosity Grade
Use SAE 0W-40 viscosity grade
engine oil.
When selecting an oil of the
appropriate viscosity grade, it is
recommended to select an oil of the
correct specification. See
“Specification” earlier in this section.
For the LT1 and LT4 engines only,
if 0W-40 dexos2 oil is not available,
SAE 5W-30 dexos1 full synthetic
engine oil may be used for
street use.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil. The
recommended oils meeting the
dexos2 specification are all that is
needed for good performance and
engine protection.
Engine oil system flushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.
What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean your
skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags
containing used engine oil. See the
manufacturer's warnings about the
use and disposal of oil products.
Used oil can be a threat to the
environment. If you change your
own oil, be sure to drain all the oil
from the filter before disposal. Never dispose of oil by putting it in the
trash or pouring it on the ground,
into sewers, or into streams or
bodies of water. Recycle it by taking
it to a place that collects used oil.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer that
indicates when to change the
engine oil and filter. This is based
on a combination of factors which
include engine revolutions, engine
temperature, and miles driven.
Based on driving conditions, the
mileage at which an oil change is
indicated can vary considerably. For
the oil life system to work properly,
the system must be reset every time
the oil is changed.
Z06, Grand Sport, ZR1, and
Stingray with Z51 have a
racetrack-ready dry sump engine
lubrication system. This high
performance system operates
differently than a standard engine
lubrication system and requires a

Cooling System (Engine)
The cooling system allows the
engine to maintain the correct
working temperature.

{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. See Recommended Fluids
and Lubricants 0321. The fluid
requires changing at certain
intervals. See Maintenance
Schedule 0312.
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 0247.
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 mixture of 40% DEX-COOL
coolant and 60% clean, drinkable
water. If using this mixture, nothing
else needs to be added. This
mixture:
. Gives freezing protection down
to−28 °C (−18 °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.
Caution
Do not use anything other than a
mix of DEX-COOL coolant that
meets GM Standard
GMW3420 and clean, drinkable
water. Anything else can cause
damage to the engine cooling
system and the vehicle, which
would not be covered by the
vehicle warranty.
Never dispose of engine coolant by
putting it in the trash, pouring it on
the ground, or into sewers, streams,
or bodies of water. Have the coolant
changed by an authorized service
center, familiar with legal
requirements regarding used
coolant disposal. This will help
protect the environment and your
health. If ambient temperatures are
anticipated below
−28 °C (−18 °F),
make sure a proper mixture ratio of
50% DEX-COOL coolant and 50%
clean, drinkable water is used.Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check to see if coolant is visible in
the coolant surge tank. If the coolant
inside the coolant surge tank is
boiling, do not do anything else until
it cools down. If coolant is visible
but the coolant level is not at or
above the cold fill line, add a
mixture of 40% DEX-COOL coolant
and 60% clean, drinkable water at
the coolant recovery tank, but be
sure the cooling system is cool
before this is done. See Engine
Overheating 0247.
The engine coolant surge tank is
toward the rear of the engine
compartment on the passenger side
of the vehicle. See Engine
Compartment Overview 0225. When the engine is cold, the coolant
level should be at the cold fill line on
the coolant surge tank.
When the engine is hot, the level
could be higher than the cold fill
line. If the coolant is below the cold
fill line when the engine is hot, there
could be a leak in the cooling
system.
If the coolant is low, add the coolant
or take the vehicle to your dealer for
service.
How to Add Coolant to the
Coolant Surge Tank
{Warning
Spilling coolant on hot engine
parts can burn you. Coolant
contains ethylene glycol and it will
burn if the engine parts are hot
enough.
