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 ªService and Owner
Publicationsº in the Index.
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 ªEngine Exhaustº in
the Index.
Engine Cooling System Inspection
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.

7-24 Throttle System Inspection
Inspect the throttle system for interference or binding,
and for damaged or missing parts. Replace parts as
needed. Replace any components that have high effort
or excessive wear. Do not lubricate accelerator and
cruise control cables.
Drive Axle Service
Check rear/front axle fluid level and add as needed.
Check constant velocity joints and axle seals for leaking.
Transfer Case
(Four-Wheel Drive) Inspection
Every 12 months or at oil change intervals, check front
axle and transfer case and add lubricant when necessary.
On manual shift transfer case, oil the control lever pivot
point. Check vent hose at transfer case for kinks and
proper installation. More frequent lubrication may be
required on off
-road use.
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 Satisfaction ProcedureYour 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.
