1996 CHEVROLET ASTRO Owners Manual

Part C: Periodic Maintenance
Inspections
Listed below are inspections and services which should
be performed
at least twice a year (for instance, each
spring and fall). You should let your GM 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 GM Service Manual. See “Service and Owner
Publications’’
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 “Engine Exhaust’’
in the Index.
Radiator and Heater Hose Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed.
Throttle Linkage Inspection
Inspect the throttle linkage for interference or binding,
and for damage or missing
parts. Replace parts as
needed. Replace any cables
that have high effort or
excessive wear.
Do not lubricate accelerator and cruise
control cables.

Drive Axle Service
Check readfront axle fluid level and add as needed.
Check constant velocity joints and axle
seals for leaking.
Transfer Case (All-Wheel Drive) Inspection
Every 12 months or at oil change intervals, check front
axle and transfer case and add lubricant when necessary.
Oil the control lever pivot point and all exposed control
linkage. 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. Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including
drums, wheel cylinders, calipers, parking brake, etc.
Check parking brake adjustment.
You may need to have
your brakes inspected more often if your driving habits
or conditions result in frequent braking.

Customer Satisfaction Procedure

Your satisfaction and goodwill are important to your
dealer and Chevrolet. Normally, any concern
you may
have with your vehicle can be handled by your selling or
servicing dealer. Your dealer has the facility, trained
technicians, special tools and up-to-date information to
promptly address
any issue which may arise. Chevrolet
has empowered its dealers to make decisions and repair
vehicles, and
they are eager to resolve your concern to
your complete satisfaction. If your concern has
not been
resolved
to your satisfaction, take the following steps:
STEP ONE -- Discuss your concern with a member
of dealer 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 Chevrolet Customer Assistance
Center by calling 1-800-222- 1020.
