Inspection

INFOID:0000000006260920

LEVEL

• Check if 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 radiator cap
tester adapter (commercial service tool) (B).

WARNING:

Never remove radiator cap when engine is hot. Serious burns
could 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:0000000006260921

WARNING:

• To avoid being scalded, never change engine coolant when the engine is hot.
• Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a

quarter of a turn to release built-up pressure. Then turn radiator cap all the way.

Remove engine under cover.

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

When draining all of engine coolant in the system, open water drain plugs on cylinder block. Refer
to

EM-90, "Setting"

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

Disconnect heater hose (1) at the position (

) in the figure.

Fill radiator, and reservoir tank if removed, to specified level.

CAUTION:

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

• When engine coolant overflows disconnected heater

hose, connect heater hose, and continue filling the engine
coolant.

• Use Genuine NISSAN Long Life Antifreeze/Coolant or

equivalent mixed with water (distilled or demineralized).

• 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.)

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

11. Repeat steps 7 through 10 two or more times with radiator cap installed until engine coolant level no

longer drops.

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 position 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 step 5, and steps from 7 to 14 until engine

coolant level no longer drops.

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) and the radiator cap tester adapter (commercial
service tool) (A), apply engine coolant to the cap seal surface.

• Replace radiator cap if there is an unusualness related to the above three.

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 connectors to prevent water from entering.

Apply water by hose to the back side of the radiator core vertically downward.

Apply water again to all radiator core surfaces once per minute.

Stop washing if any stains no longer flow out from radiator.

Blow air into the back side of radiator core vertically downward.
• Use compressed air lower than 490 kPa (5 kg/cm

, 71 psi) and keep distance more than 30 cm (11.81

in).
