General Information
Maintenance Requirements
Some regular maintenance is
essential to maintain the vehicle’s
mechanical condition, as well as its
emissions and engine performance.
It is the owner ’s responsibility to
make sure that the scheduled
maintenance, as well as general
maintenance, is performed.
As the vehicle owner, you are the
only one who can ensure that your
vehicle receives proper
maintenance. You are a vital link in
the maintenance chain.
General Maintenance
General maintenance includes
those items that should be checked
during normal day-to-day operation.
They are essential for proper
vehicle operation. It is your
responsibility to perform these
procedures regularly as prescribed. Performing general maintenance
checks requires minimal mechanical
skill and only a few general
automotive tools.
These checks or inspections can be
done by yourself, a qualified
technician, or, if you prefer, your
dealer.
Scheduled Maintenance
The maintenance items listed in this
section are required to be serviced
at regular intervals. However, under
severe driving conditions, additional
or more frequent maintenance will
be required.
Where to go for Service
If maintenance service is required or
your vehicle appears to malfunction,
have the systems checked and
serviced. It is recommended that
you visit your dealer for this service.
Chevrolet technicians are
well-trained specialists and are kept
up to date with the latest service
information through technical
bulletins, service tips, and training
programs.

Explanation of Scheduled
Maintenance Items
The following descriptions are
provided to give you a better
understanding of the scheduled
maintenance items that should be
regularly checked or replaced. The
maintenance schedule indicates at
which mileage/time intervals each
item requires service.
In addition to scheduled
maintenance, your vehicle requires
that some items be checked during
normal day-to-day operation. For
additional information, refer to
“General Maintenance” in this
section.
Items marked with * are
recommended for reliable vehicle
operation. You are not required to
perform maintenance on these

and intervals are required. When applicable, additional
information can be found under
“Vehicle Checks”
in the Vehicle
Care section of this manual.
Chevrolet does not advocate the
use of non-OEM approved
aftermarket flushing systems and
strongly advises against performing
these services on a Chevrolet
product. Many of the aftermarket
flushing systems use non-OEM
approved chemicals or solvents, the
use of which has not been validated
by Chevrolet.
For recommended fuel, lubricants,
fluids, grease, and refrigerant, refer
to Recommended Fluids and
Lubricants 0257.

piping, and connections for leaks,
looseness, or deterioration. Tighten
connections or replace parts as
necessary.
Spark plugs : Replace at specified
intervals. Install new plugs of the
same type as originally equipped.

248 Service and Maintenance
Maintenance Schedules
To help ensure smooth, safe, and
economical driving, two
maintenance schedules are
provided, depending upon the
conditions in which you usually
drive. These schedules contain both
distance and time intervals, up to
160 000 km (100,000 mi)/
120 months. For most people, the
odometer reading will indicate when
service is needed. However, if you
drive very little, your vehicle should
be serviced at the regular time
intervals shown in the schedule.
After 160 000 km (100,000 mi)/
120 months, continue maintenance
at the same mileage/time intervals.
Additional Maintenance Items for
Severe Operating Conditions
Additional maintenance items for
severe operating conditions should
be performed on vehicles that are
driven under especially demanding
conditions. Additional maintenanceitems should be performed if you
primarily operate your vehicle under
the following conditions:
.
Repeated short trips of less than
8 km (5 mi).
. Repeated short trips of less than
16 km (10 mi) with outside
temperatures remaining below
freezing.
. Operating in hot weather in
stop-and-go “rush hour”traffic.
. Extensive idling and/or low
speed driving for long distances,
such as police, taxi,
or door-to-door delivery use.
. Driving in dusty conditions.
. Driving on rough, muddy, or salt
spread roads.
. Using a car-top carrier.
For vehicles operated in Canada,
both standard and severe
maintenance items should be
performed at every interval.
Standard Maintenance
The following tables show the
standard maintenance schedule.
Depending upon weather and
atmospheric conditions, varying
road surfaces, individual driving
habits, and vehicle usage, additional
or more frequent maintenance may
be required. After 160 000 km
(100,000 mi)/120 months, continue
maintenance at the same mileage/
time interval.

System Maintenance
(1) After 64 000 km (40,000 mi) or
48 months, inspect every 16 000 km
(10,000 mi) or 12 months. Replace
the drive belts if found damaged.
(2) If operating mainly in dusty
conditions, more frequent
maintenance may be required.
(3) Periodic maintenance is not
required.
(4) First replacement interval is
168 000 km (105,000 mi) or
84 months. After first replacement,
replace every 120 000 km
(75,000 mi) or 60 months. (5)
Use only prediluted ACDelco CE
Long Life Antifreeze Coolant (blue)
or equivalent. Mixing any other type
of coolant or using non-distilled
water may reduce the life
expectancy of the factory fill coolant.
See Recommended Fluids and
Lubricants 0257.
(6) Replace spark plug when the
plug gap exceeds 1.4 mm (0.055 in)
even if within specified periodic
replacement mileage.
(7) Periodic maintenance is not
required. However, if valve noise
increased, inspect valve clearance. * Maintenance items and intervals
with * are recommended for reliable
vehicle operation. The owner need
not perform such maintenance in
order to maintain the emission
warranty or manufacturer recall
liability. Other maintenance items
and intervals are required.
