INSTALLATION
Installation is the reverse order of removal.
INSPECTION AFTER INSTALLATION
Check for leaks of engine coolant using a radiator cap tester adapter (special service tool: EG17650301)
and a 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 and A/T fluid (A/T models).
Checking Radiator CapEBS00KOK
Check valve seat of radiator cap.
–Check if valve seat is swollen to the extent that the edge of the
plunger cannot be seen when watching it vertically from the top.
–Check if valve seat has no soil and damage.
Pull negative-pressure valve to open it, and make sure that it is
completely closed when released.
–Make sure that there is no dirt or damage on the valve seat of
radiator cap negative-pressure valve.
–Make sure 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 (com-
mercial service tool) and the radiator cap tester adapter [SST],
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 filler neck to remove any waxy residue
or foreign material.
Checking RadiatorEBS00KOL
Check radiator for mud or clogging. If necessary, clean radiator as follows.
Be careful not to bend or damage radiator fins.
When radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radiator
shroud 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 surface once per minute.

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.
Water pump cannot be disassembled and should be replaced as a unit.

BASIC SERVICE PROCEDURE
NOTE:
Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pres-
sure cannot be completely released because T30 models do not have fuel return system.
CAUTION:
The fuel hose connection method used when taking fuel pressure check must not be used for
other purposes.
Be careful not to scratch or put debris around connection area when servicing, so that the quick
connector maintains sealability with O-rings inside.
When installing fuel hose quick connector, refer to EM-18, "INTAKE MANIFOLD" .
1. Release fuel pressure to zero. Refer to EC-49, "
FUEL PRESSURE RELEASE" .
2. Prepare fuel hose and fuel hose clamp for fuel pressure check, and connect fuel pressure gauge.
Use suitable fuel hose for fuel pressure check (genuine NISSAN fuel hose without quick connector).
To avoid unnecessary force or tension to hose, use moderately long fuel hose for fuel pressure check.
Do not use the fuel hose for checking fuel pressure with damage or cracks on it.
Use Pressure Gauge to check fuel pressure.
3. Remove fuel hose. Refer to EM-18, "
INTAKE MANIFOLD" .
Do not twist or kink fuel hose because it is plastic hose.
Do not remove fuel hose from quick connector.
Keep the original fuel hose to be free from intrusion of dust or foreign substances with a suitable cover.
4. Install the fuel pressure gauge as shown in the figure.
Wipe off oil or dirt from hose insertion part using cloth moist-
ened with gasoline.
Apply proper amount of gasoline between top of the fuel tube
and No.1 spool.
Insert fuel hose for fuel pressure check until it touches the
No.1 spool on fuel tube.
Use NISSAN genuine hose clamp (part number: 16439
N4710 or 16439 40U00).
When reconnecting fuel line, always use new clamps.
When reconnecting fuel hose, check the original fuel hose for
damage and abnormality.
Use a torque driver to tighten clamps.
Install hose clamp to the position within 1 - 2 mm (0.04 - 0.08
in).
Make sure that clamp screw does not contact adjacent parts.
5. After connecting fuel hose for fuel pressure check, pull the hose
with a force of approximately 98 N (10 kg, 22 lb) to confirm fuel
tube does not come off.
6. Turn ignition switch ON, and check for fuel leakage.
7. Start engine and check for fuel leakage.
8. Read the indication of fuel pressure gauge.
Do not perform fuel pressure check with system operating. Fuel pressure gauge may indicate false
readings.
During fuel pressure check, confirm for fuel leakage from fuel connection every 3 minutes.
9. If result is unsatisfactory, go to next step.
10. Check the following.
Fuel hoses and fuel tubes for cloggingTightening
torque:1 - 1.5 N·m (0.1 - 0.15 kg-m, 9 - 13 in-lb)
At idling: Approximately 350 kPa (3.5 bar, 3.57 kg/cm

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.

DTC P1111 IVT CONTROL SOLENOID VALVE
D T C P 1111 I V T C O N T R O L S O L E N O I D VA LV EPFP:23796
Component DescriptionEBS010R5
Intake valve timing control solenoid valve is activated by ON/OFF
pulse duty (ratio) signals from the ECM.
The intake valve timing control solenoid valve changes the oil
amount and direction of flow through intake valve timing control unit
or stops oil flow.
The longer pulse width advances valve angle.
The shorter pulse width retards valve angle.
When ON and OFF pulse widths become equal, the solenoid valve
stops oil pressure flow to fix the intake valve angle at the control
position.
