Inspections
Listed below are inspections and services which should
be performed at least twice a year (for instance, each
spring and fall).
You sh,ould let your dealer’s service
department
or other qualified service center do these
jobs. Make sure any necessary repairs are completed
nt once.
Proper procedures to perform these services may be
found
in a service manual. See “Service and Owner
Publications’’ in
the Index.
Steering, Suspension and Front 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.
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.
