results in failure of another part,

For detailed information concerning
specific parts covered by these
emission control systems
warranties, ask your dealer.
Replacement Parts
The emission control systems of
your vehicle were designed, built,
and tested using genuine GM parts*
and the vehicle is certified as being
in conformity with applicable federal
and California emission
requirements.
Accordingly, it is
recommended that any
replacement parts used for
maintenance or for the repair of
emission control systems be new,
genuine GM parts. The warranty obligations are not
dependent upon the use of any
particular brand of replacement
parts. The owner can elect to use
non-genuine GM parts for
replacement purposes. Use of
replacement parts which are not of
equivalent quality may impair the
effectiveness of emission control
systems.
If other than new, genuine GM parts
are used for maintenance
replacements or for the repair of
parts affecting emission control, the
owner should assure himself/herself
that such parts are warranted by
their manufacturer to be equivalent
to genuine GM parts in performance
and durability.
*
“Genuine GM parts,” when used in
connection with GM vehicles means
parts manufactured by or for GM,
designed for use on GM vehicles,
and distributed by any division or
subsidiary of GM.

22 Emission Warranty Parts List
Maintenance and Repairs
Maintenance and repairs can be
performed by any qualified service
outlet; however, warranty repairs
must be performed by an authorized
Chevrolet Low Cab Forward Truck
dealer except in a situation where
the vehicle owner is significantly
inconvenienced and when a
warranted part or a warranty station
is not reasonably available to the
vehicle owner.
In a situation where the vehicle
owner is significantly
inconvenienced, and an authorized
Chevrolet Low Cab Forward Truck
dealer is not reasonably available,
repairs may be performed at any
available service establishment or
by the owner, using any
replacement part. Chevrolet will
consider reimbursement for the
expense incurred, including
diagnosis, not to exceed the
manufacturer's suggested retail
price for all warranted parts
replaced and labor charges based
on Chevrolet's recommended time
allowance for the warranty repairand the geographically appropriate
labor rate. A part not being available
within 10 days or a repair not being
completed within 30 days
constitutes a significant
inconvenience. Retain receipts and
failed parts in order to receive
compensation for warranty repairs
reimbursable due to these
situations.
If you are in a situation where you
are significantly inconvenienced,
and it is necessary to have repairs
performed by other than a Chevrolet
Low Cab Forward Truck dealer and
you believe the repairs are covered
by emission warranties, take the
replaced parts and your receipt to a
Chevrolet Low Cab Forward dealer
for reimbursement consideration.
This applies to both the Federal
Emission Defect Warranty and
Federal Emission Performance
Warranty.
Receipts and records covering the
performance of regular maintenance
or other repairs (such as those
outlined earlier) should be retained
in the event questions arise
concerning maintenance. These
receipts and records should be
transferred to each subsequent
owner. Chevrolet will not deny
warranty coverage solely on the
absence of maintenance records.
However, Chevrolet may deny a
warranty claim if a failure to perform
scheduled maintenance resulted in
the failure of a warranty part.
Claims Procedure
As with the other warranties
covered in this booklet, take your
vehicle to any authorized Chevrolet
Low Cab Forward dealer facility to
obtain service under the emission
warranty. This should be done as
soon as possible after failing an
EPA-approved I/M test or a
California smog check test, or at
any time you suspect a defect in
a part.
Those repairs qualifying under the
warranty will be performed by any
Chevrolet Low Cab Forward dealer
at no charge. Repairs which do not
qualify will be charged to you. You
will be notified as to whether or not
