WARNING
Be sure the ignition switch is in the OFF or
LOCK position before servicing drive belt.
The engine could rotate unexpectedly.1. Visually inspect the belt for signs of unusual
wear, cuts, fraying or looseness. If the belt is
in poor condition or is loose, have it replaced
or adjusted. It is recommended that you visit
a NISSAN dealer for this service.
2. Have the belt checked regularly for condi- tion and tension in accordance with the
maintenance schedule. For additional infor-
mation, refer to the Maintenance and
schedules section of this manual.
For additional information on the Cummins 5.0L
engine drive belt, refer to the “Titan Diesel Own-
er’s Manual”.
REPLACING SPARK PLUGS
Iridium-tipped spark plugs
It is not necessary to replace iridium-tipped spark
plugs as frequently as conventional type spark
plugs because they last much longer. Follow the
maintenance log shown in the “Maintenance and
schedules” section of this manual. Do not service
iridium-tipped spark plugs by cleaning or regap-
ping.
● Always replace spark plugs with rec-
ommended or equivalent ones.

WARNING
Be sure the engine and ignition switch are
off and that the parking brake is engaged
securely.
CAUTION
Be sure to use the correct socket to re-
move the spark plugs. An incorrect socket
can damage the spark plugs.
If replacement is required, it is recommended that
you visit a NISSAN dealer for this service.
WARNING
● Operating the engine with the air
cleaner removed can cause you or oth-
ers to be burned. The air cleaner not
only cleans the air, it stops the flame if
the engine backfires. If it isn’t there, and
the engine backfires, you could be
burned. Do not drive with the air cleaner
removed, and be careful when working
on the engine with the air cleaner
removed. ●
Never pour fuel into the throttle body or
attempt to start the engine with the air
cleaner removed. Doing so could result
in serious injury.
To remove the filter from the air cleaner, push the
tabs and pull the cover upward.
The viscous paper type filter element should not
be cleaned and reused. Replace the air filter
according to the maintenance log shown in the
“Maintenance and schedules” section of this
manual.
When replacing the air filter, wipe the inside of
the air cleaner housing and the cover with a damp
cloth.
NOTE:
After installing a new air cleaner, make
sure the air cleaner cover is seated in the
housing and latch the tabs.

atmospheric conditions, varying road surfaces,
individual driving habits and vehicle usage, addi-
tional or more frequent maintenance may be re-
quired.Maintenance beyond the last period
on the tables requires similar maintenance.

NOTE:
(1) After 40,000 miles (64,000 km) or 48 months, inspect every 10,000 miles (16,000 km) or 12 months. Replace the drive belts if found
damaged.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Periodic maintenance is not required.
(4) First replacement interval is 105,000 miles (168,000 km) or 84 months. After first replacement, replace every 75,000 miles (120,000 km)
or 60 months.
(5) It is recommended that you use only Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent with proper mixture ration of
50% antifreeze and 50% demineralized or distilled water. Mixing any other type of coolant or the use of non-distilled water may reduce
the life expectancy of the factory fill coolant.
(6) Periodic maintenance is not required. However, if valve noise increased, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by NISSAN for reliable vehicle operation. The owner need not perform such
maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and intervals are
required.
