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.
