REFILLING ENGINE COOLANT
1. Install reservoir tank, and radiator drain plug.
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring.
If water drain plugs on cylinder block are removed, close and tighten them. Refer to EM-253,
"ASSEMBLY" .
2. Make sure that each hose clamp has been firmly tightened.
3. Remove air relief plug on heater hose.
4. Fill thermostat housing and reservoir tank to specified level.

Refill engine coolant up to filler neck of thermostat housing.

Pour engine coolant through engine coolant filler neck slowly of less than 2 (2-1/8 US qt, 1-3/4
Imp qt) a minute to allow air in system to escape.

Use Genuine Nissan Long Life Antifreeze/Coolant or equivalent mixed with water (distilled or
demineralized). Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRICANTS" .

When engine coolant overflows air relief hole on heater hose,
install air relief plug.
5. Install radiator cap.
6. Warm up until opening thermostat. Standard for warming-up time is approximately 10 minutes at 3,000 rpm.

Make sure thermostat opening condition by touching radiator hose (lower) to see a flow of warm water.
CAUTION:
Watch water temperature gauge so as not to overheat engine.
7. Stop engine and cool down to less than approximately 50 °C (122 °F).

Cool down using a fan to reduce the time.

If necessary, refill engine coolant up to filler neck of thermostat housing.
8. Refill reservoir tank to “MAX” level line with engine coolant. Radiator drain plug:

Engine coolant capacity
(With reservoir tank at “MAX” level):

9. Repeat steps 4 through 7 two or more times with radiator cap installed until engine coolant level no longer
drops.
10. Check cooling system for leaks with engine running.
11. Warm up engine, and check for sound of engine coolant flow while running engine from idle up to 3,000 rpm with heater temperature controller set at several position between “COOL” and “WARM”.

Sound may be noticeable at heater unit.
12. Repeat step 11 three times.
13. If sound is heard, bleed air from cooling system by repeating steps 4 through 7 until engine coolant level no longer drops.
FLUSHING COOLING SYSTEM
1. Install reservoir tank, and radiator drain plug.
CAUTION:
Be sure to clean drain plug and install with new O-ring.
If water drain plugs on cylinder block are removed, close and tighten them. Refer to EM-253,
"ASSEMBLY" .
2. Remove air relief plug on heater hose.
3. Fill thermostat housing with water until water spills from the air relief hole, then close air relief plug. Fill thermostat housing and reservoir tank with water and reinstall radiator cap.
4. Run engine and warm it up to normal operating temperature.
5. Rev engine two or three times under no-load.
6. Stop engine and wait until it cools down.
7. Drain water from the system. Refer to CO-38, "
DRAINING ENGINE COOLANT" .
8. Repeat steps 1 through 7 until clear water begins to drain from radiator. Radiator drain plug:
: 1.19 N·m (0.12 kg-m, 11 in-lb)

Removal and InstallationNBS003KR
CAUTION:

When removing water pump, be careful not to get engine coolant on drive belts.

Water pump can not be disassembled and should be replaced as a unit.

After installing water pump, connect hose and clamp securely, then check for leaks using radiator
cap tester (commercial service tool) and radiator cap tester adapter [SST: EG17650301 (J33984-
A)].
REMOVAL
1. Drain engine coolant from drain plugs on radiator and both side of cylinder block. Refer to CO-38, "Chang-
ing Engine Coolant" and EM-249, "DISASSEMBLY" .
CAUTION:

Perform this step when engine is cold.

Do not spill engine coolant on drive belts.
2. Remove following parts:

Engine front undercover

Air duct (inlet); Refer to EM-177, "AIR CLEANER AND AIR DUCT" .

Alternator, water pump and A/C compressor belt; Refer to EM-174, "DRIVE BELTS" .
3. Remove fan coupling with cooling fan, and then fan and water pump pulley.
4. Remove water pump.

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

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

Do not disassemble water pump.

Removal and InstallationNBS003KS
REMOVAL
1. Drain engine coolant from drain plugs on radiator and both side of cylinder block. Refer to CO-38, "Chang-
ing Engine Coolant" and EM-249, "DISASSEMBLY" .
CAUTION:

Perform this step when engine is cold.

Do not spill engine coolant on drive belts.
2. Remove engine cover with power tool. Refer to EM-173, "
ENGINE ROOM COVER" .
3. Remove air duct (inlet). Refer to EM-177, "
AIR CLEANER AND AIR DUCT" .
4. Disconnect water suction hose from water inlet.
5. Remove water inlet and thermostat. CAUTION:
Do not disassemble thermostat.
6. Remove intake manifolds (upper and lower). Refer to EM-179, "
INTAKE MANIFOLD" .
7. Disconnect radiator hose (upper) and water hoses from thermostat housing.
8. Disconnect heater hoses from water outlet and heater pipe.
9. Remove thermostat housing, water outlet pipe, water connector, water control valve, water outlet and heater pipe.
CAUTION:
Do not disassemble water control valve.
INSPECTION AFTER REMOVAL

Make sure that valves both in thermostat and water control valve are completely closing at normal temper-
ature.

Place a thread so that it is caught in the valves of the thermostat
and water control valve. Immerse fully in a container filled with
water. Heat while stirring. (The example in the figure shows ther-
mostat.)

The valve opening temperature is the temperature at which the
valve opens and falls from the thread.

Continue heating. Check the maximum valve lift.
NOTE:
The maximum valve lift standard temperature for water control
valve is the reference value.

After checking the maximum valve lift, lower the water tempera-
ture and check the valve closing temperature.
Standard values:

If the malfunctioning condition, when closing valve at normal temperature, or measured values are out of
the standard, replace thermostat and/or water control valve.
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Be careful not to spill engine coolant over engine room. Use rag to absorb engine coolant.

UNIFIED METER CONTROL UNIT

Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled by the
unified meter control unit, which is built into the combination meter. Unified meter control unit receives sig-
nals from unified meter and A/C amp.

Warning lamp and indicator lamp of combination meter are controlled by signals drawn from the unified
meter and A/C amp.

Odo/trip meter, shift position indicator and ICC system display segments can be checked in self-diagnosis
mode.

Meters/gauges can be checked in self-diagnosis mode.
