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.
Restraint Systems
Now and then, make sure all your belts, buckles, latch
plates, retractors, anchorages and reminder systems are
working properly. Look for any loose parts or damage.
If you see anything that might keep a restraint system
from doing its job, have it repaired.
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 hookup, 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.
