2018 Ram 3500 ignition

If the vehicle experiences a sudden loss of
engine power while being driven in heavy
snow or rain, or when plowing snow, and/or
the “SERVICE AIR FILTER” message is dis-
played on the instrument cluster along with a
chime that repeats every 60 seconds, visually
inspect the air filter for snow/ice build up or
extreme water saturation. If the air filter is
not damaged, remove all snow/ice and rein-
stall air filter. If the air filter is damaged,
replace filter element.
NOTE:
The air filter housing contains a Mass Air
Flow sensor. This sensor is critical to proper
engine operation and component longevity.
Any damage or modification to this sensor
could result in major engine and/or exhaust
aftertreatment damage. We recommend you
use Mopar brand parts.
Even though your vehicle is equipped with an
Air Filter Monitor, a visual inspection of the
air cleaner filter element is recommended
every 15,000 miles (24,000km) or
12 months – whichever occurs first.Under nocircumstances should the air cleaner filter ele-
ment exceed 30,000 miles (48,000 km) or
24 months, whichever comes first.
CAUTION!
Many aftermarket performance air filter
elements do not adequately filter the air
entering the engine. Use of such filters can
severely damage your engine.
Draining Fuel/Water Separator
Filter
There are two fuel filter assemblies. One is
located on the driver's side of the engine. The
best access to this water drain valve is from
under the hood. The second one is on the
under body, located in front of the rear axle
above the drive shaft on pick-up models. The
Chassis Cab models second filter location is
on the frame behind the front axle. The best
access to this water drain valve is from under
the vehicle.
CAUTION!
• Do not drain the fuel/water separator
filter when the engine is running.
• Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appro-
priate container.
If water is detected in the water separator
while the engine is running, or while the
ignition switch is in the ON position, the
“Water In Fuel Indicator Light” will illumi-
nate and an audible chime will be heard five
times. At this point you should stop the
engine and drain the water from both of the
filters.
CAUTION!
If the “Water In Fuel Indicator Light” re-
mains on, DO NOT START the engine be-
fore you drain water from the fuel filters to
avoid engine damage.
If the “Water In Fuel Indicator Light” comes
on and a single chime is heard while you are
driving, or with the ignition switch in the ON
253

position, there may be a problem with your
water separator wiring or sensor. See your
authorized dealer for service.
Upon proper draining of the water from both
fuel filters, the “Water In Fuel Indicator
Light” will remain illuminated for approxi-
mately 10 seconds. If the water was drained
while the engine was running, the “Water In
Fuel Indicator Light” may remain on for ap-
proximately three minutes.
NOTE:
Care should be taken in disposing of used
fluids from your vehicle. Used fluids, indis-
criminately discarded, can present a problem
to the environment. Contact an authorized
dealer, service station, or government agency
for advice on recycling programs and for
where used fluids and filters can be properly
disposed of in your area.
Drain the fuel/water separator filters when
the “Water In Fuel Indicator Light” is ON.
Within 10 minutes of vehicle shutdown, turn
the engine mounted filter drain valve (located
on the side of the filter assembly) counter-
clockwise 1/4 turn, and turn the under body
mounted filter drain valve (located on thebottom of the filter assembly) counterclock
wise 1 full turn. Then turn the ignition switch
to the ON position, and allow any accumu-
lated water to drain. Leave the drain valve
open until all water and contaminants have
been removed. When clean fuel is visible,
close the drain valves by turning them fully
clockwise, and turn the ignition switch to
OFF.
If more than a couple ounces/milliliters of
fuel have been drained, follow the directions
for “Priming If The Engine Has Run Out Of
Fuel.”
Engine Mounted Fuel Filter
Replacement
NOTE:
• Using a fuel filter that does not meet the
manufacturer's filtration and water separat-
ing requirements can severely impact fuel
system life and reliability.
• The engine mounted filter housing is equipped with a No-Filter-No-Run (NFNR)
feature. Engine will not run if:
1. No filter is installed. 2. Inferior/Non-approved filter is used.
Use of OEM filter is required to ensure
vehicle will run.
CAUTION!
• Diesel fuel will damage blacktop pavingsurfaces. Drain the filter into an appro-
priate container.
• Do not prefill the fuel filter when install-
ing a new fuel filter. There is a possibility
debris could be introduced into the fuel
filter during this action. It is best to
install the filter dry and allow the in-tank
lift pump to prime the fuel system.
1. Ensure engine is turned off.
2. Place drain pan under the fuel filter drain hose.
3. Open the water drain valve 1/4 turn coun- terclockwise and completely drain fuel
and water into the approved container.
4. Close the water drain valve.
5. Remove lid using a socket or strap wrench. Rotate counterclockwise for re-
moval. Remove used o-ring and discard it.

Priming If The Engine Has Run
Out Of Fuel
WARNING!
Do not open the high pressure fuel system
with the engine running. Engine operation
causes high fuel pressure. High pressure
fuel spray can cause serious injury or
death.
1. Add a substantial amount of fuel to the tank, approximately 2 to 5 gal (8L to
19L).
2. Turn ignition switch to the start position to engage starter for one second, return ig-
nition switch to run position. This will
activate in tank fuel pump for approxi-
mately 15 seconds. Repeat this process
twice.
3. Start the engine using the “Normal Start- ing” procedure. Refer to “Starting Proce-
dures” in “Starting and Operating” for
further information.
CAUTION!
Do not engage the starter motor for more
than 15 seconds at a time. Allow two
minutes between the cranking intervals.
NOTE:
The engine may run rough until the air is
forced from all the fuel lines.
WARNING!
Do not use alcohol or gasoline as a fuel
blending agent. They can be unstable un-
der certain conditions and be hazardous or
explosive when mixed with diesel fuel.
CAUTION!
Due to lack of lubricants in alcohol or
gasoline, the use of these fuels can cause
damage to the fuel system. NOTE:
• A maximum blend of 5% biodiesel, meet-
ing ASTM specification D-975 may be used
with your Cummins diesel engine. (Chassis
Cab models not configured with B20 capa-
bility.)
• A maximum blend of 20% biodiesel, meet- ing ASTM specification D-7467 may be
used with your Cummins diesel engine.
(Pickup models and Chassis Cab models
configured with B20 capability.)
• Use of biodiesel mixture in excess of 20% can negatively impact the fuel filter's abil-
ity to separate water from the fuel, resulting
in high pressure fuel system corrosion or
damage.
• Ethanol blends are not recommended or approved for use with your Cummins diesel
engine.
• In addition, commercially available fuel ad- ditives are not necessary for the proper
operation of your Cummins diesel engine.
