2005 DODGE RAM 2500 DIESEL engine oil

CAUTION!
The filtering medium of other aftermarket filters
may disintegrate. Debris from failed filters may plug
the piston oil cooling nozzles, resulting in scuffed
pistons and engine failure.
CAUTION!
Fill the oil filter element with clean oil before
installation. Use the same type oil that will be used
in the engine. When filling the oil filter, prevent
foreign material from falling into the filter. Severe
engine damage may occur.
Apply a light film of lubricating oil to the sealing surface
of the filter gasket before installing the filter.
CAUTION!
Overtightening may distort the threads or damage
the filter element seal.
Install the filter as specified by the filter manufacturer.
Turn the filter 3/4 to one full turn after making contact
with the gasket.
Check the condition of the threads and sealing surface on
the oil pan and drain plug.
Install the drain plug and sealing washer and tighten to
37 ft-lbs. (50 N·m).
Use only high-quality multi-grade lubricating oil in your
Cummins Diesel Engine. Choose the correct oil for your
operating conditions as outlined in the Selection of
Engine Oil.

Cummins Turbo Diesel
Fill the engine with the correct grade of new oil. The
engine capacity is 11 quarts (10.4 liters) in the crankcase
and 1 quart (.95 liter) in the lubricating oil filter.
Start the engine and operate it at idle for several minutes.
Check for leaks at the lubricating oil filter and oil pan
drain plug.
Run the engine until it has reached operating tempera-
ture, stop the engine. Wait approximately 15 minutes to
let the oil in the upper parts of the engine drain back to
the pan. Check the oil level again.
Add oil as necessary to bring the level to the “SAFE”
mark on the dipstick.
Disposing Of Used Engine Oil And Filter
Care should be taken in disposing of the used engine
fluids from your vehicle. Used fluids, indiscriminately
discarded, can present a problem to the environment.Contact your local dealer, service station, or governmen-
tal agency for advice on recycling programs and where
used fluids and filters can be safely discarded in your
area.
Drive Belt
Inspection
Check the belt for intersecting cracks.
•Transverse (across the belt width) cracks are accept-
able.
•Longitudinal (direction of belt length) cracks that
intersect with transverse cracks are NOT acceptable.
Replace the belt if it has unacceptable cracks, is frayed or
has pieces of material missing.
The engine speed sensor, located near the damper, should
be inspected for damage if a belt is frayed.

across the filter element increases, a yellow disc travels
along a graduated scale on the side of the Filter
Minder™.
The yellow disc will always show the greatest restriction
experienced by the filter element. When the disc reaches
the red zone, the filter element may need to be replaced.
There is no other time or mileage interval for changing
the air cleaner filter element.
If the vehicle experiences a sudden loss of engine power
when being driven in heavy snow or rain or when
plowing snow, check the Filter Minder™
•If the Filter Minder™ is showing a plugged filter, the
filter should be visually inspected for snow/ice build
up or extreme water saturation.
•The filter is not damaged, remove all snow/ice, rein-
stall filter and reset the Filter Minder™.A visual inspection of the air cleaner filter element is
never recommended under normal circumstances. A
badly restricted element may appear clean while a soiled
element may be quite effective in filtering particles
without restricting air flow. Rely on the Filter Minder™
to determine when a filter change is necessary.
After a new filter element is inserted, press the rubber
button on the top of the Filter Minder™. This action will
reset the yellow disc to the clean position.
CAUTION!
When using an engine cleaner or a degreaser, be sure
to wrap and tape the Filter Minder™ to protect the
plastic housing from damage and discoloration.

amount of a high quality lubricant such as MoparLock
Cylinder Lubricant 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
The fluid reservoir is located under the hood and should
be checked for fluid level at regular intervals. Fill the
reservoir with windshield washer solvent only (not ra-
diator antifreeze).
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, operate the defroster for a
few minutes to reduce the possibility of smearing or
freezing the fluid on the cold windshield. Mopar All
Weather 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.
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 is
damaged, 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 fumesto 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, fol-
low the preceding safety tips.
Exhaust System Rubber Isolator and Loop-Type
Hanger — If Equipped
Inspect surfaces whenever the vehicle is hoisted for
rubber to metal separation or deep cracks. If, however,
excessively deep localized cracks are present, or any part

of the exhaust system abnormally contacts the under-
body hardware, the isolator and/or hanger should be
replaced.
Cooling System
Cooling System Maintenance
At the intervals shown in the Maintenance Schedules
Section of the manual, the system should be drained,
flushed and filled.
Inspection
Check engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where
applicable). If coolant is dirty or rusty in appearance, the
system should be drained, flushed and refilled with fresh
coolant as specified.
Inspect the entire cooling system for leaks. Check the face
of the radiator for any accumulation of bugs, leaves, or
other foreign matter. If dirty, clean the radiator core witha garden hose. With the engine OFF, gently spray water
from the back of the radiator core. Check coolant bottle
tube for condition and tightness of connections at coolant
bottle and radiator.
Extremely cold ambient temperature may require the
addition of a “winter front” for effective operation of the
cab heating/cooling system. Make certain that a percent-
age of the radiator is exposed for adequate air flow
through the charge air cooler and automatic transmission
oil cooler. The percentage of opening must be increased
with the increasing ambient air temperature and/or
engine load. If the cooling fan can be heard cycling
frequently, increase the size of the opening in the winter
front.
Coolant bottle level check
The coolant reserve system provides a quick visual
method of determining that the coolant level is adequate.
