1. Install reservoir tank if removed and radiator drain plug.

CAUTION:
Be sure to clean drain plug and install with new O-ring.

Radiator drain plug : Refer to CO-42, "Exploded View".

• If water drain plugs on cylinder block are removed, close and tighten them. Refer to EM-228, "Disassembly and Assembly".

2. Check that each hose clamp has been firmly tightened.

3. Remove air duct (between air cleaner case and electric throttle control actuator). Refer to EM-161, "Exploded View".

4. Disconnect heater hose (1) at position (
) in the figure.

: Vehicle front

• Enhance heater hose as high as possible.

5. Fill radiator (1) to specified level.

CAUTION:
Never adhere the engine coolant to electronic equipments (alternator etc.).

• Use Genuine NISSAN Engine Coolant or equivalent in its quality mixed with water (distilled or demineralized). Refer to MA-13, "Fluids and Lubricants".

Engine coolant capacity (With reservoir tank at “MAX” level) Refer to CO-54, "Periodical Maintenance Specification".

6. Refill reservoir tank to “MAX” level line with engine coolant.

A : MAX
B : MIN

Reservoir tank engine coolant capacity (At “MAX” level)
Refer to CO-54, "Periodical Maintenance Specification".

7. Install air duct (between air cleaner case and electric throttle control actuator). Refer to EM-161, "Exploded View".

8. Install radiator cap.

9. Warm up engine until opening thermostat. Standard for warming-up time is approximately 10 minutes at 3,000 rpm.

• Check 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

.

10. Stop the engine and cool down to less than approximately 50°C (122°F).

• Cool down using fan to reduce the time.

• If necessary, refill radiator up to filler neck with engine coolant.

CAUTION:
Never adhere the engine coolant to electronic equipments (alternator etc.).

11. Refill reservoir tank to “MAX” level line with engine coolant.

12. Repeat steps 5 through 10 two or more times with radiator cap installed until engine coolant level no longer drops.

13. Check cooling system for leakage with engine running.

14. Warm up the 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.

15. Repeat step 14 three times.

16. If sound is heard, bleed air from cooling system by repeating step 5 through 10 until reservoir tank level no longer drops.
