SERVICING AND MAINTENANCE353
Engine Air Cleaner   
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.
Engine Air Cleaner Selection
The quality of replacement engine air cleaner 
varies considerably. Only high quality filters 
should be used to ensure most efficient service. 
Mopar engine air cleaners are a high quality 
filter and are recommended.
Accessory Drive Belt Inspection
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 sepa -
rated from belt body)
Rib or belt wear
Longitudinal belt cracking (cracks between 
two ribs)
Belt slips
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.
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 compe -
tent mechanic.
