Engine Oil
Checking Oil Level
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop.
The best time to check the engine oil level is about five
minutes after a fully warmed engine is shut off or before
starting the engine after it has sat overnight.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain
the oil level in the “SAFE” range. Adding 1.0 qt (1.0L) of
oil when the reading is at the bottom of the “SAFE” range
will result in an oil level at the top of the “SAFE” range
on these engines.
CAUTION!
Overfilling or underfilling will cause oil aeration or
loss of oil pressure. This could damage your engine.

Change Engine Oil
Refer to the Maintenance Schedule in Section 8.
NOTE: Under no circumstances should oil change
intervals exceed 6,000 mi (10 000 km) or six months,
whichever occurs first.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only
recommends full synthetic engine oils that meet the
American Petroleum Institute (API) categories of SM or
SM/CF, and meet the requirements of DaimlerChrysler
Material Standard MS-10725.
The manufacturer recommends the use of a full synthetic
engine oil, such as Mobil 1SAE 0W-40 or equivalent.
Engine Oil Viscosity (SAE Grade)
SAE 0W-40 engine oil is preferred for use in 6.1L Engines
within the operating temperatures shown in the engineoil viscosity chart. SAE 5W-40 Engine Oil is also allowed
for use in 6.1L Engines. The proper SAE viscosity grade
of engine oil should be selected based on the following
recommendation and be within the operating tempera-
ture shown in the engine oil viscosity chart.
392 MAINTAINING YOUR VEHICLE

The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
engine oil filler cap location, refer to the “Engine Com-
partment” illustration in this section.
Materials Added to Engine Oil
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental addi-
tives.
Disposing of Used Engine Oil and Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your authorized dealer, service
station, or governmental agency for advice on how and
where used oil and oil filters can be safely discarded in
your area.
Engine Oil Filter
The engine oil filter should be replaced at every engine
oil change.
Engine Oil Filter Selection
This manufacturer’s engines have a full-flow type oil
filter. Use a filter of this type for replacement. The quality
of replacement filters varies considerably. Only high
quality filters should be used to assure most efficient
service. MoparEngine Oil Filters are a high quality oil
filter and are recommended.
Drive Belts — Check Condition and Tension
Belt tension is controlled by means of an automatic
tensioner. Therefore, no belt tension adjustments are
required. However, belt and belt tensioner condition
should be inspected periodically and replaced if re-
quired. Improper belt tension can cause belt slippage and
failure. Low generator belt tension can cause battery
failure.

WARNING!
Fluid level should be checked on a level surface and
with the engine OFF to prevent injury from moving
parts and to ensure accurate fluid level reading. Do
not overfill. Use only manufacturer’s recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to “Fluids, Lubricants, and Genuine
Parts” in this section for the correct fluid type.
Front and Rear Suspension Ball Joints
The suspension ball joints should be inspected for exter-
nal leakage or damage when other maintenance is per-
formed.
Steering Linkage
The tie rod end ball joints should be inspected for
external leakage or damage when other maintenance is
performed.
Body Lubrication
Locks and all body pivot points, including seat tracks,
door hinges, trunk hinges, and hood hinges, should be
lubricated periodically to assure quiet, easy operation
and to protect against rust and wear. Prior to the appli-
cation of any lubricant, the parts concerned should be
wiped clean to remove dust and grit; after lubricating,
excess oil and grease should be removed. Particular
attention should also be given to hood latching compo-
nents to ensure proper function. When performing other
underhood services, the hood latch, release mechanism,
and safety catch should be cleaned and lubricated.

The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small
amount of a high quality lubricant such as MoparLock
Cylinder Lubricant or equivalent directly into the lock
cylinder.
Windshield Wiper Blades
The rubber edges of the wiper blades and the windshield
should be cleaned periodically with a sponge or soft cloth
and a mild nonabrasive cleaner. This will remove accu-
mulations of salt or road film.
Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt
from a dry windshield.
Avoid using the wiper blades to remove frost or ice from
the windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc.
Windshield Washers/Headlight Washers
The windshield washer and the headlight washer share
the same fluid reservoir. The fluid reservoir is located in
the front of the engine compartment. Be sure to check the
fluid level in the reservoir at regular intervals. Fill the
reservoir with windshield washer solvent (not radiator
antifreeze) and operate the system for a few seconds to
flush out the residual water.
When refilling the washer fluid reservoir, apply some
washer fluid to a cloth or towel and wipe the wiper
blades clean. This will help blade performance.
To prevent freeze-up of your windshield washer system
in cold weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This
rating information can be found on most washer fluid
containers.
402 MAINTAINING YOUR VEHICLE

The fluid reservoir will hold nearly 1 gal (4 l) of washer
fluid when the message “Low Washer Fluid” appears in
the Electronic Vehicle Information Center (EVIC).
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around
the washer solution.
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle isdamaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing CO, refer
to “Exhaust Gas” under “Safety Tips” in Section 2.
