2007 CHEVROLET CORVETTE oil change

When to Inspect the Engine
Air Cleaner/Filters
Inspect the air cleaner/lters at the MaintenanceII
intervals and replace them at the rst oil change
after each 50,000 mile (83 000 km) interval.
SeeScheduled Maintenance on page 433for
more information. If you are driving in dusty/dirty
conditions, inspect the lters at each engine
oil change.
How to Inspect the Engine
Air Cleaner/Filters (6.0L V8 Engine)
To inspect the air cleaner/lters, remove the lters
from the vehicle and lightly shake the lters to
release loose dust and dirt. If the lters remain
caked with dirt, new lters are required.
To inspect or replace the engine air cleaner/lters,
do the following:1. Pull the latches on each side of the cover to
open, then move the latches up and out of
the way.
2. Push the air cleaner/lter cover toward the front
of the vehicle and then pull it up and away.
3. Inspect or replace the lter. SeeNormal
Maintenance Replacement Parts on page 445.
4. Reverse Steps 1 and 2 to replace the
air cleaner/lter cover.
5. Repeat the procedure for the second
air cleaner/lter.

If you no longer have the overheat warning,
you can drive. Just to be safe, drive slower for
about 10 minutes. If the warning does not
come back on, you can drive normally.
If the warning continues and you are not
stopped, pull over, stop, and park your vehicle
right away.
If there is still no sign of steam, you can idle the
engine for three minutes while you are parked.
If you still have the warning, turn off the engine
and get everyone out of the vehicle until it
cools down. Also, see “Overheated Engine
Protection Operating Mode” later in this section.
You may decide not to lift the hood but to get
service help right away.Overheated Engine Protection
Operating Mode
If an overheated engine condition exists and the
messages COOLANT OVER TEMPERATURE
and REDUCED ENGINE POWER are displayed,
along with the Check Engine light, an overheat
protection mode which alternates ring groups of
cylinders helps prevent engine damage. In
this mode, you will notice a loss in power and
engine performance. This operating mode allows
your vehicle to be driven to a safe place in an
emergency; you may drive up to 50 miles (80 km).
Notice:After driving in the overheated
engine protection operating mode, to avoid
engine damage, allow the engine to cool before
attempting any repair. The engine oil will be
severely degraded. Repair the cause of coolant
loss, change the oil and reset the oil life
system. SeeEngine Oil on page 333.

{CAUTION:
Using the wrong replacement wheels,
wheel bolts, or wheel nuts on your vehicle
can be dangerous. It could affect the
braking and handling of your vehicle,
make your tires lose air and make you
lose control. You could have a collision
in which you or others could be injured.
Always use the correct wheel, wheel bolts,
and wheel nuts for replacement.
Notice:The wrong wheel can also cause
problems with bearing life, brake cooling,
speedometer or odometer calibration,
headlamp aim, bumper height, vehicle ground
clearance, and tire clearance to the body
and chassis.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel could
come off and cause a crash. When you
change a wheel, remove any rust or dirt
from places where the wheel attaches to
the vehicle. In an emergency, you can use
a cloth or a paper towel to do this; but be
sure to use a scraper or wire brush later,
if you need to, to get all the rust or dirt off.
{CAUTION:
Never use oil or grease on studs or the
threads of the wheel nuts. If you do, the
wheel nuts might come loose and the
wheel could fall off, causing a crash.

The proper replacement parts, uids, and
lubricants to use are listed inRecommended
Fluids and Lubricants on page 443andNormal
Maintenance Replacement Parts on page 445.
When your vehicle is serviced, make sure these
are used. All parts should be replaced and all
necessary repairs done before you or anyone else
drives the vehicle. We recommend the use of
genuine GM parts.Scheduled Maintenance
When the CHANGE ENGINE OIL message comes
on, it means that service is required for your
vehicle. Have your vehicle serviced as soon as
possible within the next 600 miles (1 000 km). It is
possible that, if you are driving under the best
conditions, the engine oil life system may
not indicate that vehicle service is necessary for
over a year. However, your engine oil and
lter must be changed at least once a year and at
this time the system must be reset. Your
dealer/retailer has trained service technicians who
will perform this work using genuine parts and
reset the system.
433

If the engine oil life system is ever reset
accidentally, you must service your vehicle within
3,000 miles (5 000 km) since your last service.
Remember to reset the oil life system whenever
the oil is changed. SeeEngine Oil Life System on
page 340for information on the Engine Oil Life
System and resetting the system.
When the CHANGE ENGINE OIL message
appears, certain services, checks, and inspections
are required. Required services are described
in the following for “MaintenanceI” and
“MaintenanceII.” Generally, it is recommended
that your rst service be MaintenanceI, your
second service be MaintenanceII, and that you
alternate MaintenanceIand MaintenanceII
thereafter. However, in some cases,
MaintenanceIImay be required more often.MaintenanceI— Use MaintenanceIif the
message comes on within 10 months since the
vehicle was purchased or MaintenanceII
was performed.
MaintenanceII— Use MaintenanceIIif the
previous service performed was MaintenanceI.
Always use MaintenanceIIwhenever the message
comes on 10 months or more since the last
service or if the message has not come on at all
for one year.
