Inspection

INFOID:0000000012197516

LEVEL

• Check that the reservoir tank engine coolant level is within the

“MIN” to “MAX” when the engine is cool.

• Adjust the engine coolant level if necessary.

CAUTION:

Refill Genuine NISSAN Long Life Antifreeze/Coolant (blue) or

equivalent in its quality mixed with water (distilled or deminer-

alized). Refer to

MA-11, "Fluids and Lubricants"

LEAKAGE

• To check for leakage, apply pressure to the cooling system with the

radiator cap tester (commercial service tool) (A) and the radiator

cap tester adapter (commercial service tool) (B).

WARNING:

Never remove radiator cap when engine is hot. Serious burns

may occur from high-pressure engine coolant escaping from

engine cooling system.

CAUTION:

Higher test pressure than specified may cause radiator dam-

age.

NOTE:

In a case that engine coolant decreases, replenish radiator with engine coolant.

• If anything is found, repair or replace damaged parts.

Draining

INFOID:0000000012197517

WARNING:

• Never remove radiator cap when engine is hot. Serious burns may occur from high-pressure engine

coolant escaping from radiator.

• Wrap a thick cloth around the radiator cap. Slowly turn it a quarter of a turn to release built-up pres-

sure. Then turn it all the way.

1. Connect drain hose.

• Use a genera-purpose hose with the dimensions show in the

figure.

B : MIN

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.

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-
