ENGINE MAINTENANCE

2.

Open radiator drain plug (1) at the bottom of radiator, and then
remove reservoir tank cap. 

3.

Remove reservoir tank if necessary, drain engine coolant, and clean reservoir tank before installing. 

4.

Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system. Refer to 

CO-6, "Flushing"

.

ENGINE COOLANT : Refilling

INFOID:0000000009190118

CAUTION:

• Do not reuse O-rings.
• Do not put additive such as waterleak preventive, since it may cause cooling waterway clogging.
• When refilling use Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent in its quality

mixed with water (distilled or demineralized). Refer to 

MA-22, "Fluids and Lubricants"

.

1.

Install reservoir tank if removed.

2.

Install radiator drain plug.

CAUTION:

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

3.

Check that each hose clamp has been firmly tightened.

4.

Fill radiator to specified level.
• Pour engine coolant through engine coolant filler neck

slowly of less than 2  (2-1/8 US qt, 1-3/4 lmp qt) a minute
to allow air in system to escape.

5.

Install radiator cap.

6.

Fill reservoir tank to “MAX” level line with engine coolant if nec-
essary.

7.

Install reservoir tank cap, and then start the engine.

8.

Warm up engine until thermostat opens. 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.

Watch water temperature gauge so as not to overheat engine.

9.

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.

10. Repeat steps 6 through 9 two or more times with radiator cap and reservoir tank cap installed until engine

coolant level no longer drops. 

11. When the coolant level of the radiator stops lowering, refill reser-

voir tank to the midpoint between the “MIN” (B) and “MAX” (A) of
the reservoir tank.

12. Check cooling system for leakage with engine running.
13. 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 positions between “COOL” and “WARM”.
• Sound may be noticeable at heater unit.

14. Repeat step 13 three times.

15. If sound is heard, bleed air from cooling system by repeating steps from 3 to 13 until engine coolant level

no longer drops. 

16. Recheck reservoir tank engine coolant level with the engine completely cold. Refer to 

MA-24, "ENGINE

COOLANT : Inspection"

.

ENGINE COOLANT : Flushing

INFOID:0000000009190119

1.

Install reservoir tank if removed, and radiator drain plug.

CAUTION:

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

2.

Fill radiator and reservoir tank with water.

3.

Run the engine and warm it up to normal operating temperature.

4.

Rev the engine two or three times under no-load.

5.

Stop the engine and wait until it cools down.

6.

Drain water from the system. Refer to 

CO-5, "Draining"

.

7.

Repeat steps 1 through 6 until clear water begins to drain from radiator.
