If your air conditioning system is
functioning properly, it is not
necessary to remove and replace
the refrigerant or compressor oil.
. A V-ribbed belt is used for the
fan belt. This type of belt
requires the tension to be
adjusted more accurately than is
required with the conventional V
belt. Inappropriate tension could
cause the belt to make noise or
break. When the fan belt is
damaged, electricity is not
properly generated or becomes
a cause of engine overheating.
You must check the tension of
the fan belt carefully.
. Use dealer-certified genuine
parts when changing the
fan belt.
. Have the vehicle inspected and
serviced at your dealer. .
The air conditioning drive belt,
if equipped, must be adjusted
after fan belt adjustment. If the
belt is not adjusted properly, the
A/C belt may experience
excessive tension, and possible
premature failure.

Customer Satisfaction
Procedure
Your satisfaction and goodwill are
important to your dealer and to
Chevrolet. Normally, any concerns
with the sales transaction or the
operation of the Chevrolet chassis,
or upfitted rear body will be resolved
by your dealer's sales or service
departments. Sometimes, however,
despite the best intentions of all
concerned, misunderstandings can
occur. If your concern has not been
resolved to your satisfaction, the
following steps should be taken:
STEP ONE : Discuss your concern
with a member of dealership
management. Normally, concerns
can be quickly resolved at that level.
If the matter has already been
reviewed with the sales, service,
or parts manager, contact the owner
of your dealership or the general
manager.

STEP TWO :If after contacting a
member of dealership management,
it appears your concern cannot be
resolved by your dealership without
further help call the Chevrolet
Customer Assistance Center at
1-800-862-4389.
We encourage you to call the
toll-free number in order to give your
inquiry prompt attention. Have the
following information available to
give the Customer Assistance
representative:
. Your name, address, and
daytime phone number.
. Vehicle Identification
Number (VIN). This is available
from the vehicle registration or
title, and on the VIN plate or the
Vehicle Certification and
Greenhouse Gas (GHG)
Emissions Plate in the cab of the
vehicle.
. Dealership name and location.
. Vehicle delivery date and
present mileage.
. Nature of the problem. When contacting Chevrolet,
remember that your concern will
likely be resolved at a dealer's
facility. That is why we suggest
following Step One first.
