Part C: Periodic
Maintenance Inspections
Listed in this part are inspections and services which
should be performed at least twice a year (for instance,
each spring and fall). You should let your 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 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
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.

Throttle System Inspection

Inspect the throttle system for interference or binding,
and for damaged or missing parts. Replace parts as
needed. Replace any components that have high effort
or excessive wear. Do not lubricate accelerator and
cruise control cables.
