• When the lock nut is loosened excessively, the idle
r pulley tilts and the correct tension adjust-
ment cannot be performed. Never loo sen it excessively (more than 45 degrees).
• Put a matching mark on the lock nut, and check turning angle with a protractor. Never visually
check the tightening angle.
2. Adjust the belt tension by turning the adjusting bolt. CAUTION:
• When checking immediately after in stallation, first adjust it to the specified value. Then, after
turning crankshaft two turns or more, re-adjust to the specified value to avoid variation in deflec-
tion between pulleys.
• When the tension adjustment is performed, the lo ck nut should be in the condition at step“2”. If
the tension adjustment is performed when the lo ck nut is loosened more than the standard, the
idler pulley tilts and the correct tens ion adjustment cannot be performed.
3. Tighten the idler pulley lock nut.
ENGINE COOLANT
ENGINE COOLANT : Inspection INFOID:0000000004806014
LEVEL CHECK • Check if the reservoir tank engine coolant level is within the “MIN” to “MAX” range when engine is cool.
• Adjust the engine coolant level as necessary.
CHECKING COOLING SYSTEM FOR LEAKS To check for leaks, apply pressure to the cooling system using suit-
able tool and Tool.
WARNING:
Never remove the radiator cap wh en the engine is hot. Serious
burns could occur from high pressure coolant escaping from
the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.
ENGINE COOLANT : Chang ing Engine Coolant INFOID:0000000004806015
WARNING:
• To avoid being scalded, do not change engine coolant when engine is hot.
• Wrap a thick cloth around radiator cap and carefully remove the cap. First, turn the cap a quarter of a
turn to release built-up pressure. Then turn the cap all the way.
CAUTION:
• Do not spill engine coolant on drive belt.

ENGINE MAINTENANCE (HR16DE)
1. Open radiator drain plug (1) at the bottom of radiator, and then remove radiator cap.
• Front
When draining all of engine coolant in the system, open
water drain plug on cylinder block. Refer to EM-96 .
CAUTION:
• Perform this step when engine is cold.
• Do not spill engine coolant on drive belt.
2. Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing. Refer to CO-16, " Component " .
3. Check drained engine coolant for contaminants such as rust, corrosion or discoloration. If contaminated, flush the engine cooling system.
REFILLING ENGINE COOLANT
1. Install the radiator drain plug. Install the reservoir tank and cylinder block drain plug, if removed for a total
system drain or for engine removal or repair.
• The radiator must be complete ly empty of coolant and water.
• Apply sealant to the threads of the cylinder bl ock drain plugs. Use Genuine High Performance
Thread Sealant or equivalent. Refer to GI-42, " Recommended Chemical Product and Sealant " .
2. If disconnected, reattach the upper radiator hose at the engine side.
3. Set the vehicle heater controls to the full HOT and heat er ON position. Turn the vehicle ignition ON with
the engine OFF as necessary to activate the heater mode.
4. Install the Tool by installing the radiator cap adapter onto the radiator neck opening. Then attach the gauge body assembly
with the refill tube and the venturi assembly to the radiator cap
adapter.
5. Insert the refill hose into the coolant mixture container that is placed at floor level. Make sure the ball valve is in the closed
position.
• Use Genuine NISSAN Long Life Anti-freeze coolant or
equivalent, mixed with distil led water or demineralized
water.
Refer to MA-15, " Anti-freeze Coolant Mixture Ratio " .
6. Install an air hose to the venturi assembly, the air pressure must be within specification.
CAUTION:
The compressed air supply must be equipped with an air dryer.
7. The vacuum gauge will begin to rise and there will be an audible hissing noise. During this process open the ball valve on the refill hose slightly. Coolant will be vi sible rising in the refill hose. Once the refill hose is
full of coolant, close the ball valve. This will purge any air trapped in the refill hose. PBIC3799E

Seat Belt Inspection " .
• Check the seat belt anchors for loose bolts, damage, or excessive wear.
• Check the seat belt webbing for any damage, cuts, fraying, or excessive wear.
• Check the retractor for smooth operation.
• Check the function of the buckles by inserting the seat belt tongue and checking for proper engagement of
the buckle and press the button on the buckle to c heck for proper release of the seat belt tongue.
CAUTION:
• After any collision, inspect all seat belt assembli es, including retractors and other attached compo-
nents, such as the guide rail set. NISSAN recomme nds replacing all seat belt assemblies in use dur-
ing a collision, unless they are not damaged an d are inspected to confirm they are operating
properly after a minor collision.
Also inspect all seat belt assemblies that are not in use during a collision, and replace any compo-
nents if damaged or not operating properly. The seat belt pre-tensioner should be replaced even if
the seat belts are not in use during a frontal coll ision where the driver and passenger air bags have
been deployed.

• If any component of the seat belt assembly is susp
ected of being damaged or not operating prop-
erly, do not repair the component. Replace the components as an assembly.
• If the seat belt webbing is cut, frayed, or damaged then replace the seat belt assembly.
• Never lubricate the seat belt buckle or tongue.
• When replacing any seat belt assembly alw ays use a Genuine NISSAN seat belt assembly.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER" INFOID:0000000004786253
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:
• To avoid rendering the SRS inoper ative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery, and wait at least 3 minutes before performing any service.
