a. Remove alternator. Refer to SC-13, "
CHARGING SYSTEM" .
b. Remove oil level gauge and oil level gauge guide. Refer to EM-27, "
OIL PAN AND OIL STRAINER" .
CAUTION:
Plug the oil level gauge guide opening to prevent oil pan from entering foreign materials.
c. Remove mounting bolts for water pipe.
d. Remove water pump housing.
5. Remove exhaust manifold and three way catalyst assembly. Refer to EM-25, "
EXHAUST MANIFOLD
AND THREE WAY CATALYST" .
6. Remove water pipe.

INSPECTION AFTER REMOVAL

Visually check if there is no significant dirt or rusting on water
pump body and vane.

Make sure that there is no looseness in vane shaft, and that it
turns smoothly when rotated by hand.

Replace water pump, if necessary.
INSTALLATION
Note the following, and install in the reverse order of removal.

When inserting water pipe end into cylinder block, apply a neutral detergent to O-ring. Then insert it imme-
diately.
INSPECTION AFTER INSTALLATION

Check for engine coolant leaks using a radiator cap tester adapter (special service tool: EG17650301)
and radiator cap tester (commercial service tool). Refer to CO-9, "
LEAK CHECK" .

Start and warm up engine. Visually check if there is no leaks of engine coolant.

WARNING:
Do not remove radiator cap when the engine is hot. Serious burns could occur from high pressure
engine coolant escaping from the radiator.
REMOVAL
1. Remove RH engine undercover.
2. Remove drive belt. Refer to EM-140, "
DRIVE BELTS" .
3. Drain engine coolant. Refer to CO-32, "
DRAINING ENGINE COOLANT" .
CAUTION:
Perform when engine is cold.
4. Support the bottom of oil pan (lower) with a floor jack etc, and remove RH engine mounting insulator (front
side of engine). Refer to EM-222, "
ENGINE ASSEMBLY" .
5. Remove water pump pulley.

Loosen the pulley bolts after fixing the pulley using a screwdriver etc.
6. Remove RH engine mounting bracket.
7. Remove water pump.

Engine coolant will leak from cylinder block, so have a receptacle ready below.
CAUTION:

Handle the water pump vane so that it does not contact any other parts.

INSPECTION AFTER REMOVAL

Visually check if there is no significant dirt or rusting on the
water pump body and vane.

Make sure that there is no looseness in the vane shaft, and that
it turns smoothly when rotated by hand.

If there are any unusualness, replace water pump assembly as
necessary.
INSTALLATION

Installation is the reverse order of removal.

Install water pump pulley with the front mark (painted white, used to prevent errors during assembly) fac-
ing the front of engine. Refer to CO-43, "
WATER PUMP" .
INSPECTION AFTER INSTALLATION

Check for leaks of engine coolant using the radiator cap tester adapter (special service tool:
EG17650301) and the radiator cap tester (commercial service tool). Refer to CO-32, "
CHECKING RADIA-
TOR SYSTEM FOR LEAKS" .

Start and warm up engine. Visually check if there is no leaks of engine coolant.

TROUBLE DIAGNOSIS

17. DETECT MALFUNCTIONING PART
Check the following.

Check camshaft position sensor (PHASE) and circuit. Refer to EC-257, "DTC P0340 CMP SENSOR
(PHASE)" .

Check crankshaft position sensor (POS) and circuit. Refer to EC-250, "DTC P0335 CKP SENSOR (POS)"
.
OK or NG
OK >> GO TO 18.
NG >> 1. Repair or replace.
2. GO TO 4.
18. CHECK ECM FUNCTION
1. Substitute another known-good ECM to check ECM function. (ECM may be the cause of an incident, but
this is a rare case.)
2. Perform initialization of NATS system and registration of all NATS ignition key IDs. Refer to BL-108,
"NATS (NISSAN ANTI-THEFT SYSTEM)" .
>> GO TO 4.
