Accessory Drive Belt Inspection
WARNING!
•Do not attempt to inspect an accessory drive belt
with vehicle running.
•When working near the radiator cooling fan, dis-
connect the fan motor lead. The fan is temperature
controlled and can start at any time regardless of
ignition switch position. You could be injured by
the moving fan blades.
•You can be badly injured working on or around a
motor vehicle. Only do service work for which you
have the knowledge and the proper equipment. If
you have any doubt about your ability to perform a
service job, take your vehicle to a competent me-
chanic.
When inspecting accessory drive belts, small cracks that
run across ribbed surface of belt from rib to rib, are
considered normal. These are not a reason to replace belt.
However, cracks running along a rib (not across) are not
normal. Any belt with cracks running along a rib must be
replaced. Also have the belt replaced if it has excessive
wear, frayed cords or severe glazing.

668 MAINTAINING YOUR VEHICLE

NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune-up to manufacturer’s specifica-
tions, should be obtained immediately.
To minimize the possibility of catalytic converter dam-
age:
•Do not shut off the engine or interrupt the ignition,
when the transmission is in gear and the vehicle is in
motion.
•Do not try to start the engine by pushing or towing the
vehicle.
•Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idle or malfunctioning operating conditions.
Cooling System
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.
686 MAINTAINING YOUR VEHICLE

WARNING!
A frayed or torn belt could rip apart in a collision and
leave you with no protection. Inspect the belt system
periodically, checking for cuts, frays, or loose parts.
Damaged parts must be replaced immediately. Do
not disassemble or modify the system. Seat belt
assemblies must be replaced after a collision if they
have been damaged (i.e., bent retractor, torn web-
bing, etc.).
FUSES
WARNING!
•When replacing a blown fuse, always use an appro-
priate replacement fuse with the same amp rating as
the original fuse. Never replace a fuse with another
fuse of higher amp rating. Never replace a blown
fuse with metal wires or any other material. Failure
to use proper fuses may result in serious personal
injury, fire and/or property damage.
•Before replacing a fuse, make sure that the ignition
is off and that all the other services are switched off
and/or disengaged.
•If the replaced fuse blows again, contact an autho-
rized dealer.
