Oil Ram 2500 2014 Service Manual

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.
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.
After the engine has warmed up, operate the defroster for
a few minutes to reduce the possibility of smearing or
freezing the fluid on the cold windshield. Windshield
washer solution used with water as directed on the
container, aids cleaning action, reduces the freezing point
to avoid line clogging, and is not harmful to paint or trim.
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
If you notice a change in the sound of the exhaust system;
or if the exhaust fumes can be detected inside the vehicle;
or when the underside or rear of the vehicle is damaged;
have an authorized technician inspect the complete ex-
haust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams
or loose connections could permit exhaust fumes to seep
into the passenger compartment. In addition, have the
exhaust system inspected each time the vehicle is raised
for lubrication or oil change. Replace as required.

WARNING!(Continued)
•To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that has
been in a tightly closed container. Keep the master
cylinder reservoir cap secured at all times. Brake
fluid in a open container absorbs moisture from the
air resulting in a lower boiling point. This may
cause it to boil unexpectedly during hard or pro-
longed braking, resulting in sudden brake failure.
This could result in a collision.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing
the brake fluid to catch fire. Brake fluid can also
damage painted and vinyl surfaces, care should be
taken to avoid its contact with these surfaces.
WARNING! (Continued)
•Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
Rear Axle And 4x4 Front Driving Axle Fluid Level
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons
the exterior surfaces of the axle assembly should be
inspected. If gear oil leakage is suspected inspect the
fluid level. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further informa-
tion. This inspection should be made with the vehicle in
a level position.
706 MAINTAINING YOUR VEHICLE

For 1500 Model axles, the fluid level should be even with
the bottom of the fill hole (within 1/4 in (6.4 mm) of edge
of hole) for the FDU215 HD front axle and C235FE rear
axle.
For all 2500/3500 Model axles, the fluid level should be
1/4 in ± 1/4 in (6.4 mm ± 6.4 mm) below the fill hole on
the 9.25 in front and 3/4 in ± 1/4 in (19 mm ± 6.4 mm) on
10.5 in rear axles. The 11.5 in rear axle level should be 1/4
in ± 1/4 in (6.4 mm ± 6.4 mm) below the fill hole.
Drain And Refill
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Lubricant Selection
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.NOTE:
The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.
Limited-Slip Differentials
1500 Model rear axles equipped with a Limited Slip
Differential require that 5 oz. (148 ml) MOPAR® Limited
Slip Additive be added to the gear lubricant. Refer to
“Fluids, Lubricants, and Genuine Parts” in “Maintaining
Your Vehicle” for further information. The MOPAR®
Limited Slip Additive should be added to the gear
lubricant whenever a fluid change is made to an axle
equipped with a Limited Slip Differential.
2500/3500 Model axles DO NOT REQUIREany limited
slip oil additive (friction modifiers).

7. Remove the dipstick again and note the fluid level onboth sides. The fluid level reading is only valid if there
is a solid coating of oil on both sides of the dipstick.
Note that the holes in the dipstick will be full of fluid
if the actual level is at or above the hole. The fluid level
should be between the “HOT” (upper) reference holes
on the dipstick at normal operating temperature. If the
fluid level is low, add fluid through the dipstick tube
to bring it to the proper level. Do not overfill.Use
ONLY the recommended fluid (see Fluids, Lubri-
cants, and Genuine Parts for fluid specifications).
After adding any quantity of oil through the dipstick
tube, wait a minimum of two minutes for the oil to
fully drain into the transmission before rechecking the
fluid level. NOTE:
If it is necessary to check the transmission below
the operating temperature, the fluid level should be
between the two “COLD” (lower) holes on the dipstick
with the fluid at 60-70°F / 16-21°C. Only use the COLD
region of the dipstick as a rough reference when setting
the fluid level after a transmission service or fluid
change. Re-check the fluid level, and adjust as required,
once the transmission reaches normal operating tempera-
ture.
CAUTION!
If the fluid temperature is below 50°F (10°C) it may
not register on the dipstick. Do not add fluid until
the temperature is elevated enough to produce an
accurate reading. Run the engine at idle, in PARK, to
warm the fluid.
8. Check for leaks. Release the parking brake.

Wheel And Wheel Trim Care
•All wheels and wheel trim, especially aluminum and
chrome plated wheels, should be cleaned regularly
with a mild soap and water to prevent corrosion.
• To remove heavy soil and/or excessive brake dust, use
MOPAR® Wheel Cleaner.
NOTE: If your vehicle is equipped with Dark Vapor
Chrome wheels DO NOT USE wheel cleaners, abrasives
or polishing compounds. They will permanently damage
this finish and such damage is not covered by the New
Vehicle Limited Warranty. USE ONLY MILD SOAP AND
WATER WITH A SOFT CLOTH. Used on a regular basis
this is all that is required to maintain this finish.
CAUTION!
Do not use scouring pads, steel wool, a bristle brush,
or metal polishes. Do not use oven cleaner. These
products may damage the wheel’s protective finish.
Avoid automatic car washes that use acidic solutions
or harsh brushes that may damage the wheel’s pro-
tective finish. Only MOPAR® Wheel Cleaner or
equivalent is recommended.

MAINTAINING YOUR VEHICLE 715

•For tough stains, apply MOPAR® Total Clean, or a
mild soap solution to a clean, damp cloth and remove
stain. Use a fresh, damp towel to remove soap residue.
• For grease stains, apply MOPAR® Multi-Purpose
Cleaner to a clean, damp cloth and remove stain. Use
a fresh, damp towel to remove soap residue.
• Do not use any harsh solvents or any other form of
protectants on Stain Repel products.
Interior Care
Use MOPAR® Total Clean to clean fabric upholstery and
carpeting.
Use MOPAR® Total Clean to clean vinyl upholstery.
MOPAR® Total Clean is specifically recommended for
leather upholstery. Your leather upholstery can be best preserved by regular
cleaning with a damp soft cloth. Small particles of dirt
can act as an abrasive and damage the leather upholstery
and should be removed promptly with a damp cloth.
Stubborn soils can be removed easily with a soft cloth
and MOPAR® Total Clean. Care should be taken to avoid
soaking your leather upholstery with any liquid. Please
do not use polishes, oils, cleaning fluids, solvents, deter-
gents, or ammonia-based cleaners to clean your leather
upholstery. Application of a leather conditioner is not
required to maintain the original condition.
WARNING!
Do not use volatile solvents for cleaning purposes.
Many are potentially flammable, and if used in
closed areas they may cause respiratory harm.

To Help Maintain The Appearance Of Your Spray-On
Bedliner, Follow The Steps Below:
1. Rinse your truck bed out with water to remove anyloose dirt and debris.
2. Mix a mild soap or detergent with water with a soft cloth or brush.
3. Rinse bedliner with water.
4. Once dry, apply a small amount of MOPAR® Spray-On Bedliner Conditioner to a moist towel or
sponge and wipe over the entire surface of the truck
bedliner.
WARNING!
Do not use silicon-based protection products to clean
your bedliner. Silicon-based products can become
slippery and may result in personal injury. Spray-On Bedliners are chemically-resistant to many
different types of chemicals (including gasoline, oil,
hydraulic fluids) for short periods of time. If a spill
occurs on your Spray-On Bedliner, rinse the truck out as
soon as possible to avoid permanent damage.
Repairing The Spray-On Bedliner
While extremely tough, it is possible to damage a
Spray-On Bedliner. One common condition is when
loading a heavy pallet and dragging that pallet across the
floor of the bed. If a nail or sharp point is exposed under
the weight of the pallet a scratch or tear is possible. While
not covered by your new vehicle warranty, a cosmetic fix
to cover the metal exposed by the scratch is required. To
repair a tear or gouge, follow the directions provided in
the MOPAR® Quick Repair Kit.
