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 ªService and Owner
Publicationsº 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 ªEngine Exhaustº 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.
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. Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including
drums, wheel cylinders, calipers, parking brake, etc.
Check parking brake adjustment. You may need to have
your brakes inspected more often if your driving habits
or conditions result in frequent braking.
