< PERIODIC MAINTENANCE >

ENGINE MAINTENANCE

• 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.

CAUTION:

Refill Genuine NISSAN Long Life Antifreeze/Coolant (blue) or
equivalent in its quality mixed with water (distilled or demineral-
ized). Refer to 

MA-15, "FOR NORTH AMERICA : Fluids and

Lubricants"

 (FOR NORTH AMERICA). or 

MA-16, "FOR MEXICO :

Fluids and Lubricants"

 (FOR MEXICO).

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
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.

ENGINE COOLANT : Draining

INFOID:0000000009722382

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.

1.

Remove engine under cover.

2.

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"

.

3.

Remove reservoir tank if necessary, and 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-13, "Flushing"

.

• 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-15, "FOR NORTH AMERICA : Fluids and

Lubricants"

 (for North America) or Refer to 

MA-16, "FOR MEXICO : Fluids and Lubricants"

 (for Mex-

ico).

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-123, "Dis-

assembly and Assembly"

.

2.

Check that each hose clamp has been firmly tightened.

3.

Remove air duct assembly and air cleaner cases (upper and lower) assembly. Refer to 

EM-31, "Exploded

View"

.

4.

Disconnect heater hose (1) at the position (

) in the figure.

5.

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.

ENGINE MAINTENANCE

6.

Install air duct assembly and air cleaner cases (upper and lower) assembly. Refer to 

EM-31, "Exploded

View"

.

7.

Install radiator cap.

8.

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.

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.

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.

RADIATOR CAP

RADIATOR CAP : Inspection

INFOID:0000000009722385

• Check valve seat (A) of radiator cap. 
- Check if valve seat is swollen to the extent that the edge of the

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

- Check if valve seat has no soil and damage.
- 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) 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.

CAUTION:

When installing radiator cap, thoroughly wipe out the radiator pipe (upper) filler neck to remove any
waxy residue or foreign material.
