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.
