242 SERVICING AND MAINTENANCE

Engine Air Cleaner Filter

Refer to the "Maintenance Plan" in this section
for the proper maintenance intervals.
NOTE:
Be sure to follow the "Severe Duty Conditions"
maintenance interval if applicable.
WARNING!
The air induction system (air cleaner, hoses,
etc.) can provide a measure of protection in
the case of engine backfire. Do not remove
the air induction system (air cleaner, hoses,
etc.) unless such removal is necessary for
repair or maintenance. Make sure that no
one is near the engine compartment before
starting the vehicle with the air induction
system (air cleaner, hoses, etc.) removed.
Failure to do so can result in serious
personal injury.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner
filters varies considerably. Only high quality
filters should be used to ensure most efficient
service. Mopar engine air cleaner filters are a
high quality filter and are recommended.

Accessory Drive Belt Inspection

WARNING!
Do not attempt to inspect an accessory drive

belt with vehicle running.
When working near the radiator cooling fan,

disconnect the fan motor lead. The fan is
temperature controlled and can start at any
time regardless of ignition mode. 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 mechanic.
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.
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)


"Groove jumping" (belt does not maintain

correct position on pulley)


before new belt is installed)
Noise (objectionable squeal, squeak, or rumble
