GENERAL INFORMATION 0B-13
Weather-Strip Lubrication
Apply a thin film silicone grease using a clean cloth.
EACH TIME THE OIL IS CHANGED
Brake System Inspection
This inspection should be done when the wheels are
removed for rotation. Inspect the lines and the hoses
for proper hookup, binding, leaks, cracks, chafing, etc.
Inspect the disc brake pads for wear. Inspect the rotors
for surface condition. Inspect other brake parts, the
parking brake, etc., at the same time. Inspect the brakes
more often if habit or conditions result in frequent braking.
Steering, Suspension and Front Drive Axle
Boot And Seal Inspection
Inspect the front and rear suspension and the steering
system for damaged, loose or missing parts, signs of
wear or lack of lubrication. Inspect the power steering
line and the hoses for proper hookup, binding, leaks,
cracks, chafing, etc. Clean and inspect the drive axle
boot and seals for damage, tears or leakage. Replace
the seals if necessary.
Exhaust System Inspection
Inspect the complete system (including the catalytic
converter if equipped). 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 heat
buildup in the floor pan or could let exhaust fumes seep
into the trunk or passenger compartment.
Throttle Linkage Inspection
Inspect the throttle linkage for interference or binding,
damaged, or missing parts. Lubricate all linkage joints
and throttle cable joints, the intermediate throttle shaft
bearing, the return spring at throttle valve assembly, and
the accelerator pedal sliding face with suitable grease.
Check the throttle cable for free movements.
Engine Drive Belts
Inspect all belts for cracks, fraying, wear and proper
tension. Adjust or replace the belts as needed.
Hood Latch Operation
When opening the hood, note the operation of the
secondary latch. It should keep the hood from opening
all the way when the primary latch is released. The hood
must close firmly.
AT LEAST ANNUALLY
Lap and Shoulder Belts Condition and
Operation
Inspect the belt system including: the webbing, the
buckles, the latch plates, the retractor, the guide loops
and the anchors.
Movable Head Restraint Operation
On vehicles with movable head restraints, the restraints
must stay in the desired position.
Spare Tire and Jack Storage
Be alert to rattles in the rear of the vehicle. The spare
tire, all the jacking equipment, and the tools must be
securely stowed at all times. Oil the jack ratchet or the
screw mechanism after each use.
Key Lock Service
Lubricate the key lock cylinder.
Body Lubrication Service
Lubricate all the body door hinges including the hood,
the fuel door, the rear compartment hinges and the
latches, the glove box and the console doors, and any
folding seat hardware.
Underbody Flushing
Flushing the underbody will remove any corrosive
materials used for ice and snow removal and dust control.
At least every spring clean the underbody. First, loosen
the sediment packed in closed areas of the vehicle. Then
flush the underbody with plain water.
Engine Cooling System
Inspect the coolant and freeze protection fluid. If the fluid
is dirty or rusty, drain, flush and refill the engine cooling
system with new coolant. Keep the coolant at the proper
mixture in order to ensure proper freeze protection,
corrosion protection and engine operating temperature.
Inspect the hoses. Replace the cracked, swollen, or
deteriorated hoses. Tighten the clamps. Clean the
outside of the radiator and the air conditioning
condenser. Wash the filler cap and the neck. Pressure
test the cooling system and the cap in order to help
ensure proper operation.

Problems in the steering, the suspension, the tires, and
the wheels involve several systems. Consider all systems
when you diagnose a complaint. Some problems, such
as abnormal or excessive tire wear and scuffed tires,
may by the result of hard driving. Always road test thevehicle first. If possible, do this road test with the
customer.
Proceed with the following preliminary checks. Correct
any substandard conditions.
