• As for the bolt holes (B), normally apply liquid gasket inside

the holes. Occasionally, it should be applied outside the holes.
Check to read the text of service manual.

• Within five minutes of liquid gasket application, install the mat-

ing component.

• If liquid gasket protrudes, wipe it off immediately.
• Never retighten after mounting bolts and nuts the installation.
• After 30 minutes or more have passed from the installation, fill

engine oil and engine coolant.

CAUTION:

If there are specific instructions in this manual, observe them.

ENGINE COOLANT

Inspection

INFOID:0000000005518090

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
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:0000000005518091

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.

ENGINE COOLANT

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"

.

Refilling

INFOID:0000000005518092

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-122, "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.

• Use Genuine NISSAN Long Life Antifreeze/Coolant or

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

MA-15, "FOR NORTH AMERICA : Fluids and Lubri-

cants"

 (for North America) or 

MA-16, "FOR MEXICO : Fluids

and Lubricants"

 (for Mexico).
