Inspection

INFOID:0000000005988456

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.

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
radiator.

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:0000000005988457

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.

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.

2.

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

CO-14, "Exploded View"

.

3.

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

CO-11, "Flushing"

Refilling

INFOID:0000000005988458

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 plugs on cylinder block are removed, close and tighten them. Refer to EM.

2.

Check that each hose clamp has been firmly tightened.

3.

Remove air duct inlet and air cleaner assembly. Refer to 

EM-24, "Removal and Installation"

.

4.

Disconnect heater hose (1) at position (

) in the figure.

• 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.).
• 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. 

• Use Genuine NISSAN Engine Coolant or equivalent in its

quality mixed with water (distilled or demineralized). Refer
to 

MA-8, "Fluids and Lubricants"

.

6.

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

7.

Install air duct (between air cleaner case and electric throttle control actuator). Refer to 

EM-24, "Removal

and Installation"

.

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. 

Flushing

INFOID:0000000005988459

Remove air duct inlet and air cleaner case assembly. Refer to 

EM-24, "Removal and Installation"

.

3.

Disconnect heater hose (1) at position (

) in the figure.

• Enhance heater as high as possible.
