WATER PUMP
lEngine coolant will leak from cylinder block, so have a receptacle ready below.
CAUTION:
lHandle the water pump vane so that it does not contact any other parts.
lWater pump cannot be disassembled and should be replaced as a unit.
INSPECTION AFTER REMOVAL
lVisually check if there is no significant dirt or rusting on the
water pump body and vane.
lMake sure that there is no looseness in the vane shaft, and that
it turns smoothly when rotated by hand.
lIf there are any unusualness, replace water pump assembly as
necessary.
INSTALLATION
lInstall in the reverse order of removal.
lInstall cooling fan (crankshaft driven type) with the front mark “AISIN” facing the front of engine. Refer to
CO-19, "
Removal and Installation".
INSPECTION AFTER INSTALLATION
lCheck for leaks of engine coolant using the radiator cap tester adapter [SST: EG17650301] and the radia-
tor cap tester (commercial service tool). Refer toCO-7, "
CHECKING RADIATOR SYSTEM FOR LEAKS".
lStart and warm up engine. Visually check if there is no leaks of engine coolant.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EKS00N1V
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 and SB section of
this Service Manual.
WARNING:
lTo 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 per-
formed by an authorized NISSAN/INFINITI dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
