2. Open radiator drain plug (A) at the bottom of radiator, and then

remove radiator cap. 

CAUTION:

Perform this step when engine is cold.

• When draining all of engine coolant in the system, open water

drain plugs on cylinder block. Refer to 

EM-72, "Setting"

.

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

Refer to 

CO-16, "Exploded View"

.

4. Check drained engine coolant for contaminants such as rust, corrosion or discoloration. If contaminated,

flush the engine cooling system. Refer to 

CO-12, "Flushing"

.

5. Disconnect drain hose.

Refilling

INFOID:0000000012197518

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-11, "Fluids and Lubricants"

.

1. Install reservoir tank if removed, and install 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-72, "Setting"

.

2. Check that each hose clamp has been firmly tightened.
3. Remove air duct (suction side). Refer to 

EM-27, "Exploded View"

.

4. Disconnect vacuum hose break booster side, and removal vacuum tube from clamp. Refer to 

BR-42,

"Exploded View"

.

5. Disconnect heater hose (1) at position (

) in the figure.

• Enhance heater hose as high as possible.

6.  Fill radiator (1) to specified level.

CAUTION:

Never adhere the engine coolant to electronic equipments

(alternator etc.).
• Pour coolant slowly of less than 2   (2-1/8 US qt, 1-3/4

Imp qt) a minute to allow air in system to escape.

• When engine coolant overflows disconnected heater

hose, connect heater hose, and continue filling the engine

coolant.

ENGINE COOLANT

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

8. Install air duct (suction side). Refer to 

EM-27, "Exploded View"

.

9. Install radiator cap.
10. 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.

11. 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.).

12. Refill reservoir tank to “MAX” level line with engine coolant.
13. Repeat steps 6 through 11 two or more times with radiator cap installed until engine coolant level no

longer drops. 

14. Check cooling system for leakage with engine running.
15. 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.

16. Repeat step 15 three times.
17. If sound is heard, bleed air from cooling system by repeating step 6 through 11 until reservoir tank level no

longer drops. 

Flushing

INFOID:0000000012197519

1. Install 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-72, "Setting"

.

2. Remove air duct (suction side), air cleaner cover assembly and air cleaner body assembly. Refer to 

EM-

27, "Exploded View"

.

3. Disconnect vacuum hose break booster side, and remove vacuum tube from clamp. Refer to .

4. Disconnect heater hose (1) at position (

) in the figure.

• Enhance heater as high as possible.

5. Fill radiator and reservoir tank with water and reinstall radiator cap.

• When engine coolant over flows disconnected heater hose, connect heater hose, and continue filling the

engine coolant.

6. Connect vacuum hose, and install vacuum tube. 
7. Install air duct (suction side), air cleaner cover assembly and air cleaner body assembly. Refer to

INFOID:0000000012197520

• Check valve seat (A) of radiator cap. 

- Check that valve seat is swollen to the extent that the edge of the

plunger cannot be seen when watching it vertically from the top.

- Check that valve seat has no soil and damage.

• Pull negative-pressure valve to open it, and that it close completely

when released.

- Check that there is no dirt or damage on the valve seat of radiator

cap negative-pressure valve. 

- Check 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 (commer-

cial service tool) (A) and the radiator cap tester adapter (commer-

cial service tool) (B), 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.

RADIATOR
RADIATOR : Inspection

INFOID:0000000012197521

Check radiator for mud or clogging. If necessary, clean radiator as follows.

CAUTION:

• Be careful not to bend or damage radiator fins.

• When radiator is cleaned without removal, remove all surrounding parts such as radiator cooling fan

assembly and horns. Then tape harness and harness 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 surfaces once per minute.
3. Stop washing if any stains no longer flow out from radiator.
