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 retailer’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 an Aurora service manual. See “Service and
Owner Publications’’ in the Index.
Steering, Suspension and Front-Wheel-Drive
Axle Boot and Seal 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. Clean and then inspect the drive axle boot seals for
damage, tears or leakage. Replace seals if necessary.
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.
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.
