SERVICING AND MAINTENANCE
251
When inspecting accessory drive belts, small
cracks that run across the ribbed surface of a 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.
Accessory Belt (Serpentine Belt)
Conditions that would require replacement:
Rib chunking (one or more ribs has separated
from belt body)
Rib or belt wear
Longitudinal belt cracking
(cracks between two ribs)
Belt slips
“Groove jumping" (belt does not maintain
correct position on pulley)
Belt broken
NOTE:
Identify and correct problem before new belt is
installed
Noise (objectionable squeal, squeak, or rumble
is heard or felt while drive belt is in operation).
Some conditions can be caused by a faulty
component such as a belt pulley. Belt pulleys
should be carefully inspected for damage and
proper alignment.
Belt replacement on some models requires the
use of special tools; we recommend having your
vehicle serviced at an authorized dealer.

For best possible performance, your air conditioner
should be checked and serviced by an authorized
dealer at the start of each warm season. This
service should include cleaning of the condenser
fins and a performance test. Drive belt tension
should also be checked at this time.
WARNING!
Use only refrigerants and compressor lubri
-
cants approved by the manufacturer for your
air conditioning system. Some unapproved
refrigerants are flammable and can explode,
injuring you. Other unapproved refrigerants or
lubricants can cause the system to fail,
requiring costly repairs. Refer to Warranty
Information located online, for further
warranty information.
The air conditioning system contains refrig
-
erant under high pressure. To avoid risk of
personal injury or damage to the system,
adding refrigerant or any repair requiring lines
to be disconnected should be done by an
experienced technician.
CAUTION!
Do not use chemical flushes in your air
conditioning system as the chemicals can
damage your air conditioning components. Such
damage is not covered by the New Vehicle
Limited Warranty.
