GMC YUKON DENALI 2003 Owners Manual

Part C: Periodic Maintenance
Inspections
Listed in this part are inspections and services which
should be performed at least twice a year (for instance,
each spring and fall).
You should let your dealer’s
service department or other qualified service center do
these jobs. Make sure any necessary repairs are
completed at once.
Proper procedures
to perform these services may be
found in a service manual. See Service Publications
Ordering Information on page
7- IO.
Steering and Suspension Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts, signs of
wear or lack of lubrication. Inspect the power steering
lines and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body
near the exhaust system. Look for broken, damaged,
missing or out-of-position parts as well as open seams,
holes, loose connections or other conditions which
could cause a heat build-up in the floor pan or could let
exhaust fumes into the vehicle. See Engine Exhaust
on page 2-29.
Fuel System Inspection
Engine Cooling System Inspection
Inspect the complete fuel system for damage or leaks.
Inspect the hoses and have them replaced
if they
are cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed. Clean the
outside of the radiator and air conditioning condenser.
To help ensure proper operation, a pressure test of
the cooling system and pressure cap is recommended
at least once a year.
Transfer Case and Front Axle
(All-Wheel Drive) Inspection
Every 12 months, or at engine oil change intervals,
check front axle and transfer case and add lubricant
when necessary.
A fluid loss could indicate a problem.
Check and have it repaired,
if needed. Check vent
hose at transfer case for kinks and proper installation.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear and rotors
for surface condition. Inspect other brake parts,
including calipers, parking brake, etc. You may need
to
have your brakes inspected more often if your driving
habits or conditions result in frequent braking.

Customer Assistance Information
Customer Satisfaction Procedure
Your satisfaction and goodwill are important to
your dealer and to GMC. Normally, any concerns with
the sales transaction or the operation of your vehicle 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 the dealership or
the general manager.
STEP TWO: If after contacting a member of dealership
management] it appears your concern cannot be
resolved by the dealership without further help, contact
the GMC Consumer Relations Manager by calling
1 -800-GMC-8782 (1 -800-462-8782, Customer
Assistance prompt). In Canada, contact GM of Canada
Customer Communication Centre in Oshawa by calling
1-800-263-3777 (English) or 1-800-263-7854 (French). We encourage you
to call
the toll-free number in order to
give your inquiry prompt attention. Please have the
following information available
to give the Customer
Assistance Representative:
Vehicle Identification Number (This is available from
the vehicle registration or title, or the plate at the top
left of the instrument panel and visible through the
windshield.)
Dealership name and location
Vehicle delivery date and present mileage
When contacting GMC, please remember that your
concern will likely be resolved at a dealer’s facility.
That is why we suggest you follow Step One first
if you
have a concern.
STEP THREE: Both General Motors and your dealer
are committed
to making sure you are completely
satisfied with your new vehicle. However,
if you continue
to remain unsatisfied after following the procedure
outlined in Steps One and Two, you should file with the
GM/BBB Auto Line Program
to enforce any additional
rights you may have. Canadian owners refer to
your Warranty and Owner Assistance Information
booklet for information on the Canadian Motor Vehicle
Arbitration Plan (CAMVAP).
