2018 Ram 4500 Chassis Cab engine oil

Heavy Duty Use Of The Vehicle
Change engine oil at 4,000 miles (6,500 km)
or 350 hours of engine run time if the vehicle
is operated in a dusty and off road environ-
ment or is operated predominately at idle or
only very low engine RPM’s. This type of
vehicle use is considered Severe Duty.
SCHEDULED MAINTENANCE — 6.7L
CUMMINS DIESEL ENGINE
CAUTION!
Failure to perform the required mainte-
nance items may result in damage to the
vehicle.
At Each Stop For Fuel
Check the engine oil level at least 30 minutes
after a fully warmed engine is shut off.
Checking the oil level while the vehicle is on
level ground will improve the accuracy of the
oil level reading. Add oil only when the level
is at or below the ADD or MIN mark. Once A Month
• Inspect the batteries, and clean and
tighten the terminals as required.
• Check the fluid levels of the coolant reser- voir, brake master cylinder, and automatic
transmission (if equipped), and add as
needed.
At Each Oil Change
• Change the engine oil filter.
• Inspect the exhaust system.
• Inspect engine air filter.
• Check the coolant level, hoses, and clamps.
• Inspect front end, and lubricate — If equipped with serviceable fittings.
• Lube the front drive shaft fitting (4X4 mod- els only).
Inspection and service should also be per-
formed anytime a malfunction is observed or
suspected. Retain all receipts.
Oil Change Indicator System —
Cummins Diesel
Your vehicle is equipped with an engine oil
change indicator system. This system will
alert you when it is time to change your
engine oil by displaying the words “Oil
Change Due” in your instrument cluster dis-
play. The oil change reminder will remind the
owner to change the engine oil every
15,000 miles or 500 hours, whichever
comes first, except for the Chassis Cab mod-
els and Pickup models configured with op-
tional B20 capability that are using B20 bio-
diesel, which are 12,500 miles or 400 hours,
whichever comes first. Failure to change the
engine oil per the maintenance schedule can
result in internal engine damage.
Replace the engine oil and oil filter every
15,000 miles (24,000 km) or six months, or
sooner if prompted by the oil change indicator
system. Under no circumstances should oil
change intervals exceed 15,000 miles
(24,000 km) or six months, whichever comes
first.

NOTE:
• Under no circumstances should oil changeintervals exceed 15,000 miles
(24,000 km) or six months or 500 Hours,
whichever comes first.
• Replace the engine oil and oil filter every 12,500 miles (20 000 km) when running
B20 fuel (Chassis Cab Only).
If Chassis Cab models and Pickup models
configured with optional B20 capability are
operated with greater than 5% levels of bio-
diesel, the oil change interval must not ex-
ceed 12,500 miles (20 000 km) under any
circumstances. See the Fuel Requirements
section for more information regarding opera-
tion of Chassis Cab models and Pickup mod-
els configured for use with biodiesel blend
(B6-B20) fuel meeting ASTM specification
D-7467.Perform Service Indicator —
Cummins Diesel
Your vehicle will require emissions mainte-
nance at a set interval. To help remind you
when this maintenance is due, the instru-
ment cluster will display “Perform Service”.
When the “Perform Service” message is dis-
played on the instrument cluster it is neces-
sary to have the emissions maintenance per-
formed. Emissions maintenance may include
replacing the Closed Crankcase Ventilation
(CCV) filter element. The procedure for clear-
ing and resetting the “Perform Service” indi-
cator message is located in the appropriate
Service Information.

6. Remove the used filter cartridge from thehousing and dispose of according to your
local regulations.
7. Wipe clean the sealing surfaces of the lid and housing.
8. Install new o-ring back into ring groove on the filter housing and lubricate with clean
engine oil.
9. Remove new filter cartridge from plastic bag and install into housing.
NOTE:
Do not remove cartridge from bag until
you reach this step in order to keep car-
tridge clean.
10. Push down on the cartridge to ensure it is properly seated. Do not pre-fill the filter
housing with fuel.
11. Install lid onto housing and tighten to 22.5 ft lbs (30.5 N.m). Do not over-
tighten the lid.
12. Prime the engine using the procedure in “Priming If The Engine Has Run Out Of
Fuel.” Then start the engine and confirm
there are no leaks.Underbody Mounted Fuel Filter
Replacement
NOTE:
• Using a fuel filter that does not meet themanufacturer's filtration and water separat-
ing requirements can severely impact fuel
system life and reliability.
• The underbody mounted filter housing will cause the engine not to run if:
1. No filter is installed.
CAUTION!
• Diesel fuel will damage blacktop paving surfaces. 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 full turn counterclockwise 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.
6. Remove the used filter cartridge from the housing and dispose of according to your
local regulations.
7. Wipe clean the sealing surfaces of the lid and housing.
8. Install new o-ring back into ring groove on the filter housing and lubricate with clean
engine oil.
NOTE:
WIF sensor is re-usable. Service kit comes
with new o-ring for filter canister and WIF
sensor.
