ENGINE OIL
Engine Oil Selection
Use only the manufacturer's recommended fluids Úpage 278.
NOTE:Hemi engines at times can tick right after startup and then
quiet down after approximately 30 seconds. This is normal
and will not harm the engine. This characteristic can be
caused by short drive cycles: for example, if the vehicle is
started then shut off after driving a short distance. Upon
restarting, you may experience a ticking sound. Other
causes could be if the vehicle is unused for an extended
period of time, incorrect oil, extended oil changes or
extended idling. If the engine continues to tick or if the
Malfunction Indicator Light (MIL) comes on, see the
nearest authorized dealer.
WARNING!

Battery fluid is a corrosive acid solution and can burn
or even blind you. Do not allow battery fluid to
contact your eyes, skin, or clothing. Do not lean over
a battery when attaching clamps. If acid splashes in
eyes or on skin, flush the area immediately with large
amounts of water
Úpage 216.

posts and free of corrosion.
 If a “fast charger” is used while the battery is in the
vehicle, disconnect both vehicle battery cables
before connecting the charger to the battery. Do not
use a “fast charger” to provide starting voltage.
CAUTION!
Precautions have been taken to safeguard all parts and
connections however, the pressures generated by these
machines is such that complete protection against
water ingress cannot be guaranteed.
WARNING!
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

ACCESSORY DRIVE BELT INSPECTION
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)
 Belt slips
 Groove jumping (belt does not maintain correct
position on pulley)
 Belt broken (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.
BODY LUBRICATION
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, decklid, sliding doors and hood hinges, should be
lubricated periodically with a lithium-based grease, such
as Mopar® Spray White Lube to ensure quiet, easy
operation and to protect against rust and wear. Prior to the
application of any lubricant, the parts concerned should
be wiped clean to remove dust and grit; after lubricating,
excess oil and grease should be removed.
WARNING!
 Do not attempt to inspect an accessory drive belt
with vehicle running.
 When working near the radiator cooling fan, discon -
nect 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.
