RADIATOR CAP : InspectionINFOID:0000000003793170
 Check valve seat (A) of radiator cap.
- Check if valve seat is swollen to the extent that the edge of the
plunger (B) cannot be seen when watching it vertically from the
top.
- Check if valve seat has no soil and damage.
- Check that there is no dirt or damage on the valve seat of radiator
cap negative-pressure valve.
- Check that there are no unusualness in the opening and closing
conditions of negative-pressure valve.
 Check radiator cap relief pressure.
- When connecting radiator cap to the radiator cap tester (commer-
cial service tool) and the radiator cap tester adapter (commercial
service tool) (A), apply engine coolant to the cap seal surface.
 Replace radiator cap if there is an unusualness related to the above three.
CAUTION:
When installing radiator cap, thoroughly wipe out the radiator pipe (upper) filler neck to remove any
waxy residue or foreign material.

RADIATOR : InspectionINFOID:0000000003793171
Check radiator for mud or clogging. If necessary, clean radiator as follows:
CAUTION:
 Be careful not to bend or damage radiator fins.
 When radiator is cleaned without removal, remove all surrounding parts such as radiator cooling fan
assembly and horns. Then tape harness and connectors to prevent water from entering.
1. Apply water by hose to the back side of the radiator core vertically downward.
2. Apply water again to all radiator core surfaces once per minute.
3. Stop washing if any stains no longer flow out from radiator.
4. Blow air into the back side of radiator core vertically downward.
 Use compressed air lower than 490 kPa (4.9 bar, 5 kg/cm
2, 71 psi) and keep distance more than 30 cm
(11.81 in).
5. Blow air again into all the radiator core surfaces once per minute until no water sprays out.

b. Pull plunger stopper tab (A) up (or turn lever downward) so as to
remove plunger stopper tab from the ratchet of plunger (D).
NOTE:
Plunger stopper tab and lever (C) are synchronized.
c. Push plunger into the inside of tensioner body.
d. Hold plunger in the fully compressed position by engaging
plunger stopper tab with the tip of ratchet.
e. To secure lever, insert stopper pin (E) through hole of lever into
tensioner body hole (B).
 The lever parts and the tab are synchronized. Therefore, the
plunger will be secured under this condition.
NOTE:
Figure shows the example of 1.2 mm (0.047 in) diameter thin screwdriver being used as the stopper pin.
f. Install timing chain tensioner (primary).
 Remove dust and foreign material completely from backside of timing chain tensioner (primary) and
from installation area of rear timing chain case.
g. Remove stopper pin (A).
h. Check again that timing chain and water pump sprocket are engaged.
4. Install valve timing control cover (bank 1) and water pump cover as follows:
a. Before installing, remove all traces of old liquid gasket from mating surface of water pump cover using
scraper. Also remove traces of old liquid gasket from the mating surface of front timing chain case.
b. Apply a continuous bead of liquid gasket with the tube presser
(commercial service tool) to mating surface of water pump cover
(1).
Use Genuine Liquid Gasket or equivalent.
CAUTION:
Attaching should be done within 5 minutes after coating.
c. Tighten mounting bolts.
5. Install water drain plug (front) on water pump side of cylinder block.
 Apply liquid gasket to the thread of water drain plug (front).
Use Genuine Liquid Gasket or equivalent.
6. Install in the reverse order of removal after this step.
After starting engine, let idle for three minutes, then rev engine up to 3,000 rpm under no load to
purge air from the high-pressure chamber of chain tensioner. Engine may produce a rattling
noise. This indicates that air still remains in the chamber and is not a matter of concern.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003940045
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the “SRS AIRBAG” and
“SEAT BELT” of this Service Manual.
WARNING:
• To avoid rendering the SRS inoperative, 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 incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIRBAG”.
 Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
