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 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 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.
Tire and Wheel Inspection
Inspect the tires for uneven wear or damage. If there is
irregular or premature wear, check the wheel alignment.
Inspect for damaged wheels.
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. 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.
Rear Axle Service
Check the gear lubricant level in the rear axle and add if
needed. See “Rear Axle” in the Index.
A fluid loss may
indicate a problem. Check the axle and repair it
if needed.
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, parlung brake, etc. You may need to
have your brakes inspected more often if your driving
habits or conditions result in frequent braking.
