open hood CHEVROLET CORVETTE 2010 6.G Owners Manual

Gasoline Octane
If the vehicle has the 6.2L V8 engine (VIN Code W), use
premium unleaded gasoline with a posted octane rating
of 91 or higher. You can also use regular unleaded
gasoline rated at 87 octane or higher, but the vehicle's
acceleration could be slightly reduced, and a slight
audible knocking noise, commonly referred to as spark
knock, might be heard. If the octane is less than 87,
a heavy knocking noise might be heard when driving.
If this occurs, use a gasoline rated at 87 octane or
higher as soon as possible. Otherwise, you could
damage the engine. If heavy knocking is heard when
using gasoline rated at 87 octane or higher, the engine
needs service.
If the vehicle has the 6.2L V8 engine (VIN Code T)
or the 7.0L V8 engine (VIN Code E), use premium
unleaded gasoline with a posted octane rating of 91
or higher. For best performance, use premium unleaded
gasoline with a posted octane rating of 93. In an
emergency, you can use regular unleaded gasoline
with an octane rating of 87 or higher. If 87 octane fuel is
used, do not perform any aggressive driving maneuvers
such as wide open throttle applications. You might also
hear audible spark knock during acceleration. Refill the
tank with premium fuel as soon as possible to avoid
damaging the engine. If heavy knocking is heard when
using gasoline rated at 91 octane or higher, the engine
needs service.
Gasoline Specifications
At a minimum, gasoline should meet ASTM
specification D 4814 in the United States or
CAN/CGSB‐3.5 or 3.511 in Canada. Some gasolines
contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT).
We recommend against the use of gasolines containing
MMT. See Additives
on page 6‑8for additional
information.
California Fuel
If the vehicle is certified to meet California Emissions
Standards, it is designed to operate on fuels that
meet California specifications. See the underhood
emission control label. If this fuel is not available in
states adopting California emissions standards, the
vehicle will operate satisfactorily on fuels meeting
federal specifications, but emission control system
performance might be affected. The malfunction
indicator lamp could turn on and the vehicle might fail
a smog‐check test. See Malfunction Indicator Lamp
on
page 4‑41. If this occurs, return to your authorized
dealer/retailer for diagnosis. If it is determined that the
condition is caused by the type of fuel used, repairs
might not be covered by the vehicle warranty.

Filling a Portable Fuel Container
{WARNING:
Never fill a portable fuel container while it is in
the vehicle. Static electricity discharge from the
container can ignite the fuel vapor. You can be
badly burned and the vehicle damaged if this
occurs. To help avoid injury to you and others:
.Dispense fuel only into approved containers.
.Do not fill a container while it is inside a
vehicle, in a vehicle's trunk, pickup bed,
or on any surface other than the ground.
.Bring the fill nozzle in contact with the inside
of the fill opening before operating the nozzle.
Contact should be maintained until the filling is
complete.
.Do not smoke while pumping fuel.
.Do not use a cellular phone while
pumping fuel.
Checking Things Under
the Hood
{WARNING:
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing, and tools away from any
underhood electric fan.
{WARNING:
Things that burn can get on hot engine parts and
start a fire. These include liquids like fuel, oil,
coolant, brake fluid, windshield washer and other
fluids, and plastic or rubber. You or others could
be burned. Be careful not to drop or spill things
that will burn onto a hot engine.

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, 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 Air Cleaner/Filter
See Engine Compartment Overviewon page 6‑14for
the location of the engine air cleaner/filter.
Notice: If you spray water into the engine air
cleaner/filter intake and water enters the engine
air cleaner/filter housing, you could damage your
vehicle's engine. The repairs would not be covered
by your warranty. Do not spray water into the
engine air cleaner/filter intake and/or housing. If you are cleaning the vehicle with the hood open, take
care not to spray water directly near the filter opening of
the air cleaner, as shown in the illustration, as this could
damage the vehicle's engine.
When to Inspect the Engine Air Cleaner/
Filter
Inspect the air cleaner/filter at the Maintenance
II
intervals and replace them at the first oil change after
each 80 000 km (50,000 mile) interval. See Scheduled
Maintenance
on page 7‑3for more information. If you
are driving in dusty/dirty conditions, inspect the filter at
each engine oil change.
How to Inspect the Engine Air Cleaner/
Filter
To inspect the air cleaner/filter, remove the filter from
the vehicle and lightly shake the filter to release loose
dust and dirt. If the filter remains caked with dirt, a new
filter is required.

To inspect or replace the engine air cleaner/filter: 1. Open the hood. See Hood Release on page 6‑13.

If you do decide to lift the hood , make sure the vehicle
is parked on a level surface.
Then check to see if the engine cooling fan is running.
If the engine is overheating, the fan should be running.
If it is not, do not continue to run the engine and have
the vehicle serviced.
Notice: Engine damage from running your engine
without coolant is not covered by your warranty.
See Overheated Engine Protection Operating Mode
on page 6‑41for information on driving to a safe
place in an emergency.
Notice: If the engine catches fire while driving
with no coolant, the vehicle can be badly damaged.
The costly repairs would not be covered by the
vehicle warranty. See Overheated Engine Protection
Operating Mode
on page 6‑41for information on
driving to a safe place in an emergency.
If Steam Is Coming From Your Engine
{WARNING:
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Turn it off and get everyone away from
the vehicle until it cools down. Wait until there
is no sign of steam or coolant before you open
the hood.
If you keep driving when the vehicles engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop the engine if
it overheats, and get out of the vehicle until the
engine is cool.
See Overheated Engine Protection Operating
Mode
on page 6‑41for information on driving to
a safe place in an emergency.

4. Open the hoods and locate the positive (+) and negative (−) terminal locations on each vehicle.
6.2 L LS3 shown, 7.0 L LS7 and 6.2 L LS9 similar
Your vehicle has a remote positive (+) terminal (A)
and a remote negative (−) terminal (B), as shown in
the illustration, which should be used to jump start
your vehicle. The remote positive (+) terminal (A) can be
accessed by opening the cover of the engine
compartment fuse block.
The remote negative (−) terminal (B) is located
underneath the engine cover, below the engine oil
fill cap.
See
Engine Compartment Overview
on page 6‑14for the location of the engine compartment fuse
block and engine oil fill cap.
You will not need to access the battery for jump
starting. The remote terminals are for that purpose.
{WARNING:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.
