2021 NISSAN TITAN air condition

Exhaust system:Visually inspect the ex-
haust pipes, muffler and hangers for leaks,
cracks, deterioration and damage. Tighten
connections or replace parts as necessary.
For additional information, see “Exhaust
gas (carbon monoxide)” (P. 5-4).
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks af ter the
vehicle has been parked for a while. Water
dripping from the air conditioner af ter use
is normal. If you should notice any leaks or if
fuel fumes are evident, check for the cause
and have it corrected immediately.
Power steering fluid level* and lines:
Check the level when the fluid is cold, with
the engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Radiator and hoses Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances from the underbody, otherwise
rust may form on the floor pan, frame, fuel
lines and exhaust system. At the end of winter, the underbody should be thor-
oughly flushed with plain water, in those
areas where mud and dirt may have accu-
mulated. For additional information, see
“Cleaning exterior” (P. 7-2).
Windshield-washer fluid*:
Check that
there is adequate fluid in the reservoir. The following descriptions are provided to
give you a better understanding of the
scheduled maintenance items that should
be regularly checked or replaced. The
maintenance schedule indicates at which
mileage/time intervals each item requires
service.
Items marked with
“*”are recommended
by NISSAN for reliable vehicle operation.
You are not required to perform mainte-
nance on these items in order to maintain
the warranties which come with your
NISSAN. Other maintenance items and in-
tervals are required.
When applicable, additional information
can be found in the “Do-it-yourself ” section
of this manual.
NOTE: NISSAN does not advocate the use
of non-OEM approved af termarketflushing systems and strongly advisesagainst performing these services on aNISSAN product. Many of the af termar-ket flushing systems use non-OEM ap-proved chemicals or solvents, the use ofwhich has not been validated by NISSAN.
For recommended fuel, lubricants, fluids,
grease, and refrigerant, see “Recom-
mended fluids/lubricants and capacities”
(P. 10-2).
EXPLANATION OF SCHEDULED
MAINTENANCE ITEMS
Maintenance and schedules9-5

EMISSION CONTROL SYSTEM
MAINTENANCE:
Drive Belts*:Check engine drive belts for
wear, fraying or cracking and for proper
tension. Replace any damaged drive belts.
Engine Air Filter: Replace at specified in-
tervals. When driving for prolonged periods
in dusty conditions, check/replace the filter
more frequently.
Engine Coolant*: Replace coolant at the
specified interval. When adding or replac-
ing coolant, be sure to use only Genuine
NISSAN Long Life Antifreeze/Coolant (blue)
or equivalent with the proper mixture. (For
additional information on the proper mix-
ture for your area, see “Engine cooling sys-
tem” (P. 8-6)).
NOTE: Mixing any other type of coolant or
the use of non-distilled water may reduce
the recommended service interval of the
coolant.
Engine Oil and Oil Filter: Replace engine
oil and oil filter at the specified intervals. For
recommended oil grade and viscosity see
“Recommended fluids/lubricants and ca-
pacities” (P. 10-2). Engine Valve Clearance*:
Inspect only if
valve noise increases. Adjust valve clear-
ance if necessary.
Evaporative Emissions Control Vapor
Lines*: Check vapor lines for leaks or loose-
ness. Tighten connections or replace parts
as necessary.
Fuel Lines*: Check the fuel hoses, piping
and connections for leaks, looseness, or
deterioration. Tighten connections or re-
place parts as necessary.
CHASSIS AND BODY
MAINTENANCE:
Brake Lines and Cables: Visually inspect
for proper installation. Check for chafing,
cracks, deterioration, and signs of leaking.
Replace any deteriorated or damaged
parts immediately.
Brake Pads and Rotors: Check for wear,
deterioration and fluid leaks. Replace any
deteriorated or damaged parts immedi-
ately.
Exhaust System: Visually inspect the ex-
haust pipes, muffler and hangers for leaks,
cracks, deterioration, and damage. Tighten
connections or replace parts as necessary. In-Cabin Microfilter:
Replace at specified
intervals. When driving for prolonged peri-
ods in dusty conditions, replace the filter
more frequently.
Propeller Shaf t(s): Check for damage,
looseness, and grease leakage. (4WD/
AWD/RWD).
Steering Gear and Linkage, Axle and Sus-
pension Parts, Drive Shaf t Boots: Check
for damage, looseness, and leakage of oil
or grease. Under severe driving conditions,
inspect more frequently.
Tire Rotation: Rotate tires at the specified
interval shown in the maintenance sched-
ule. When rotating tires, check for damage
and uneven wear. Replace if necessary.
Transmission Fluid/Oil, Differential Oil,
Transfer Case Oil: Visually inspect for signs
of leakage at specified intervals.
Replace automatic transmission fluid at
specified intervals.
If towing a trailer, using a camper or car-top
carrier, or driving on rough or muddy roads:
• Replace the differential oil every 20,000 miles (32,000 km) or 24 months.
•
Replace the automatic transmission fluid
ever 30,000 miles (48,000 km) or 24 months.
9-6Maintenance and schedules

Off-Road Maintenance:Check the follow-
ing items frequently whenever you drive
off-road through deep sand, mud or water:
• Brake pads and rotors
• Brake lines and hoses
• Differential, transmission and transfer case oil
• Steering linkage
• Propeller shaf t(s) and front drive shaf ts
• Engine air filter
• Clutch housing drain (4WD only) To help ensure smooth, safe and economi-
cal driving, NISSAN provides two mainte-
nance schedules that may be used, de-
pending upon the conditions in which you
usually drive. These schedules contain
both distance and time intervals, up to
120,000 miles (192,000 km)/96 months. For
most people, the odometer reading will in-
dicate when service is needed. However, if
you drive very little, your vehicle should be
serviced at the regular time intervals
shown in the schedule.
Af ter 120,000 miles (192,000 km)/96
months, continue maintenance at the
same mileage/time intervals.
ADDITIONAL MAINTENANCE ITEMS
FOR SEVERE OPERATING
CONDITIONS
Additional maintenance items for severe
operating conditions
should be per-
formed on vehicles that are driven under
especially demanding conditions. Addi-
tional maintenance items should be per-
formed if you primarily operate your vehicle
under the following conditions:
• Repeated short trips of less than 5 miles in normal temperatures or less than 10
miles in freezing temperatures. • Stop-and-go traffic in hot weather or low
speed driving for long distances.
• Driving in dusty conditions or on rough, muddy or salt-spread roads.
• Towing a trailer, or using a camper or car- top carrier.
If your vehicle is mainly operated under the
severe conditions, follow the severe main-
tenance intervals shown in the mainte-
nance schedule.
