Required Maintenance For Noise Control Systems
The following maintenance services must be performed
every six months or 7,500 miles (12 000 km) whichever
comes first, to assure proper operation of the noise
control systems. In addition, inspection and service
should be performed anytime a malfunction is observedor suspected. Proper maintenance of the entire vehicle
will help the effectiveness of the noise control systems.
Exhaust System
Inspect the entire exhaust system for leaks and damaged
parts. Devices such as hangers, clamps, and U-bolts
should be tight and in good condition. Damaged compo-
nents, burned or blown out mufflers, burned or rusted
out exhaust pipes should be replaced according to the
procedures and specifications outlined in the appropriate
service manual.
Air Cleaner Assembly
Inspect air cleaner housing for proper assembly and fit.
Make certain that the air cleaner is properly positioned
and that the cover is tight. Check all hoses leading to the
air cleaner for tightness. The air filter element must also
be clean and serviced according to the instructions out-
lined in the Maintenance Schedule section of this manual.7

Engine Coolant We recommend you use MOPAR Antifreeze/Coolant 10 Year/150,000 Mile Formula OAT (Organic Additive Technology).
Engine Oil In ambient temperatures above 0°F (-18°C), we recommend you use 15W-40 engine oil such
as MOPAR, Shell Rotella and Shell Rimula that meets FCA Material Standard MS-10902 and
the API CJ-4 engine oil category is required. Products meeting Cummins CES 20081 may
also be used. The identification of these engine oils is typically located on the back of the
oil container.
In ambient temperatures below 0°F (-18°C), we recommend you use 5W-40 synthetic
engine oil such as MOPAR, Shell Rotella and Shell Rimula that meets FCA Material
Standard MS-10902 and the API CJ-4 engine oil category is required.
