If contaminated, flush engine cooling system. Refer to CO-34, "FLUSHING COOLING SYSTEM" .
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 plug on cylinder block is removed, close and tighten it. Refer to EM-235, "ASSEM-
BLY" .
2. Remove air relief plug.
3. Fill radiator and reservoir tank to the specified level.

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

Use Genuine Nissan Anti-freeze Coolant or equivalent
mixed with water (distilled or demineralized). Refer to
MA-17, "
RECOMMENDED FLUIDS AND LUBRICANTS".

When engine coolant overflows air relief hole, install air relief
plug with new copper washer.
4. Install radiator cap.
5. Warm up until opening thermostat and water control valve. 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.
6. 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 radiator up to filler neck with engine coolant.
7. Refill reservoir tank to “MAX” level line with engine coolant.
8. Repeat steps 3 through 6 two or more times with radiator cap installed until engine coolant level no longer
drops.
9. Check cooling system for leaks with engine running.

10. 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.
11. Repeat step 10 three times.
12. If sound is heard, bleed air from cooling system by repeating steps 3 through 6 until engine coolant level
no longer drops.
FLUSHING COOLING SYSTEM
1. Install reservoir tank if removed, and radiator drain plug.
CAUTION:
Be sure to clean drain plug and install with new O-ring.

If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-235, "ASSEM-
BLY" .
2. Fill radiator with water until water spills from the air relief hole, then close air relief plug. Fill radiator and
reservoir tank with water and reinstall radiator cap.
3. Run engine and warm it up to normal operating temperature.
4. Rev engine two or three times under no-load.
5. Stop engine and wait until it cools down.
6. Drain water from the system. Refer to CO-32, "
DRAINING ENGINE COOLANT" .
7. Repeat steps 1 through 6 until clear water begins to drain from radiator.

REMOVAL
1. Drain engine coolant from radiator. Refer to CO-32, "Changing Engine Coolant" .
CAUTION:
Perform when engine is cold.
2. Remove air duct (inlet) and air duct assembly. Refer to EM-142, "
AIR CLEANER AND AIR DUCT" .
3. Disconnect radiator hose (upper) at radiator side. Refer to CO-12, "
RADIATOR" .
CAUTION:
Do not spill engine coolant on drive belt.
4. Disconnect harness connectors from fan motors, and move them to aside.
5. Remove radiator cooling fan assembly. Refer to CO-35, "
RADIATOR" .
CAUTION:
Be careful not to damage or scratch on radiator core.
INSTALLATION
Installation is the reverse order of removal.

Cooling fans are controlled by ECM. For details, refer to EC-1124, "DTC P0217 ENGINE OVER TEM-
PERATURE" (WITH EURO-OBD), EC-1480, "DTC P0217 ENGINE OVER TEMPERATURE" (WITHOUT
EURO-OBD).
DISASSEMBLY AND ASSEMBLY
Disassembly
1. Remove cooling fans.
2. Remove cooling fan motor (RH and LH) from cooling fan shroud.

Put marks to identify installation positions of cooling fan motor.

THERMOSTAT AND WATER PIPING

INSPECTION AFTER REMOVAL
Thermostat

Place a string so that it is caught in the valves of the thermostat.
Immerse fully in a container filled with water. Heat while stirring.

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

Continue heating. Check the full-open lift amount.

After checking the full-open lift amount, lower the water temper-
ature and check the valve closing temperature.
Standard values

If out of the standard, replace thermostat.
INSTALLATION
Note the following, and install in the reverse order of removal.

Install the thermostat with the whole circumference of each
flange part fit securely inside the rubber ring.

Install the thermostat with the jiggle valve facing upwards.
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.
