o-44 Maintenance and Lubrication
Periodic Maintenance Inspection
Steering and Suspension Inspection
Inspect the front and the rear suspension for the
following:
• Damaged parts
• Loose or missing parts
• Signs of wear or lack of lubrication
Inspect the power steering lines and the hoses for the
following:
• Proper hookup
• Binding
• Leaks
• Cracks
• Chafing, etc.
Tire and Wheel Inspection
Inspect the tires for uneven wear or damage. If there
is irregular or premature wear, test the wheel
alignment. Inspect for damaged wheels. For tire
diagnosis information, refer to Abnormal or Excessive
Tire Wear in Suspension.
For wheel alignment diagnosis information, refer to
Preliminary Alignment Inspection in Suspension.
Exhaust System Inspection
Inspect the complete 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. For exhaust system
inspection diagnosis refer to Exhaust System
Inspection in Engine Exhaust.
Engine Cooling System Inspection
Caution: NEVER spray water on a hot radiator. The
resulting steam could cause personal injury.
Notice: Compressed air or water can be used to clean
the radiator fins. Do not exceed 138 kPa (20 psi).
Pressure over 138 kPa (20 psi) will damage the
radiator.
Inspect and replace the radiator hoses if they are
cracked, swollen, or deteriorated.
Inspect all of the pipes, the fittings, and the clamps
and replace as needed.
Important: The radiator and the A/C condenser
should be kept clean to ensure proper system
performance. Cleaning is recommended at least once
a year.
Inspect the front surface of the radiator and the A/C
condenser. Insects, leaves, debris, etc. can affect
the performance of the radiator and the A/C
condenser.
If the front surface of either or both of these
components requires cleaning, the unwanted material
can be removed by performing the following:
• Ensure that the engine is off and cool.
• Blow compressed air through the radiator from the
rear surface of the radiator toward the front of the
vehicle.
General Information
• If compressed air is not available, use a water
hose to force water through the radiator from
the rear surface of the radiator toward the front of
the vehicle.
To help ensure proper cooling system pressure, a
pressure test of the cooling system and pressure cap
is recommended at least once a year.
Throttle System Inspection
The throttle system (including the accelerator and the
cruise control) should operate freely and without
hesitation between full closed and wide open t~rottle.
Important: The accelerator and the cruise control
cables should NOT be lubricated under any
circumstance. Any throttle system components
causing hesitation or sticking should be replaced.
Inspect for the following:
• Missing parts such as retainers or clips.
• Interference of the linkage or the cable cooduit to
critical components such as fuel lines, brake ·
lines, harness leads, etc.
• Proximity of the cable to the exhaust system and
other heat sources. Inspect for melting and/or
discoloration.
• Cable kinking. Avoid sharp bends in cables.
• Clearance of the throttle system's moving parts
throughout their travel from other stationary
components.
• Damage of any components due to cable kinking,
severe abrasion, misalignment, etc. If any of the
above conditions exist, see your dealer for a
rerouting, adjustment, or replacement
recommendation.
Brake System Inspection
Inspect the entire brake system.
Notice: A low brake fluid level can indicate worn disc
brake pads which may need to be serviced. Also,
if the brake system warning light stays on or comes
on, something may be wrong with the brake system. If
the anti-lock brake system warning light stays on or
comes on, something may be wrong with the anti-lock
brake system.
Inspect the brake lines and the hoses for the following:
• Proper hookup
• Binding
• Leaks
• Cracks
• Chafing, etc.
Inspect the disc brake pads for wear. Inspect the
surface condition of the rotors. Inspect all other brake
parts including the calipers, the parking brake, etc.
The brakes may need to be inspected more often
if driving habits or conditions result in frequent braking.
