Engine Oil
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0228.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil (Except
Stingray with Z51 and Z06)
If the ENGINE OIL LOW–ADD OIL
message displays on the Driver
Information Center (DIC), check the
engine oil level right away. See
Engine Oil Messages 0123. Check
the engine oil level regularly.
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle
must be on level ground. The
engine oil dipstick handle is a loop.
See Engine Compartment Overview
0 218 for the location of the engine
oil dipstick.
Obtaining an accurate oil level
reading is essential:
1. If the engine has been running recently, turn off the engine and
check within five and
10 minutes of shutoff.
Checking the oil level too soon
after engine shutoff will not
provide an accurate oil level
reading.

5. Turn the air cleaner/filterendcap downward and
disengage the lower endcap
mounting tabs from the lower
retention hinge features. Be
sure to insert the lower endcap
mounting tabs fully into the
housing retention hinge
features before turning the
endcap upward and replacing
the screws.
6. Inspect or replace the air cleaner/filter.
7. Reverse Steps 1–6 to replace the air cleaner/filter endcap.
8. Replace the extractor hood duct. See above.
{Warning
Operating the engine with the air
cleaner/filter off can cause you or
others to be burned. The air
cleaner not only cleans the air; it
helps to stop flames if the engine
backfires. Use caution when
working on the engine and do not
drive with the air cleaner/filter off.
Caution
If the air cleaner/filter is off, dirt
can easily get into the engine,
which could damage it. Always
have the air cleaner/filter in place
when you are driving.
Cooling System (Engine)
The cooling system allows the
engine to maintain the correct
working temperature.

{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.
Caution
Using coolant other than
DEX-COOL®can cause
premature engine, heater core,
or radiator corrosion. In addition,
the engine coolant could require
changing sooner. Any repairs
would not be covered by the
vehicle warranty. Always use
DEX-COOL (silicate-free) coolant
in the vehicle.

Cooling System (Aero
Panel)
The aero panel enhances
aerodynamic efficiency and
improves fuel economy.
Remove the aero panel and bracket
to improve engine cooling and air
conditioning performance when
driving aggressively or in hot
weather.
To remove the aero panel and
bracket:
Non-Z51 and Z51 Shown, Z06Similar
1. Press up on the two indents at the bottom and lift the aero
panel off the bracket.Non-Z51 and Z51 Shown, Z06

2. Unscrew the two fasteners that secure the bracket.
3. Gently pull the bracket away from the grille.
To replace the bracket and aero
panel: 1. Position the bracket over the grille.
2. Secure the bracket by pushing the two fasteners into place.
3. Snap the aero panel into place.

Engine Coolant
The cooling system in the vehicle is
filled with DEX-COOL®engine
coolant. See Recommended Fluids
and Lubricants 0307. The fluid
requires changing at certain
intervals. See Maintenance
Schedule 0298.
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 0237.
What to Use
{Warning
Adding only plain water or some
other liquid to the cooling system
can be dangerous. Plain water
and other liquids, 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
(Continued)
Warning (Continued)
could get too hot but you would
not get the 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.
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
If improper coolant mixture,
inhibitors, or additives are used in
the vehicle cooling system, the
engine could overheat and be
damaged. Too much water in the
mixture can freeze and crack
engine cooling parts. The repairs
would not be covered by the
vehicle warranty. Use only the
proper mixture of engine coolant
for the cooling system. See
Recommended Fluids and
Lubricants 0307.
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.
