Inspection

INFOID:0000000001062331

LEVEL

1.

Check if the reservoir tank coolant level is within MIN to MAX
when engine is cool.

2.

Adjust coolant if too much or too little.

LEAKAGE

• To check for leakage, fit the adapter to the reservoir tank, and then

connect it to the tester [SST: — (M.S. 554-07)] (A) as shown.

• Warm up the engine and turn it off.
• To check for leaks, apply pressure to the cooling system with the

radiator cap tester and radiator reservoir cap tester adapter.

• If the pressure drops, look for leakage.
• Unscrew slowly the adapter from the reservoir tank to reduce the

pressure in cooling system, and install the reservoir tank cap.

WARNING:

Never remove the radiator cap when the engine is hot. Serious burns could occur from high pressure
engine coolant escaping from the radiator.

CAUTION:

Higher pressure than specified may cause radiator damage.

Draining

INFOID:0000000001062332

WARNING:

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

release built-up pressure. Then turn the cap all the way.

1.

Remove engine undercover.

2.

Disconnect reservoir tank hose (lower) (1) from radiator and
remove reservoir tank cap.

3.

Remove air relief plug from water outlet. Refer to

CO-62,

"Exploded View"

.

4.

Remove reservoir tank, then clean reservoir tank.

5.

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

CO-53,

"Flushing"

.

Refilling

INFOID:0000000001062333

• Before start working, turn off the automatic air conditioner and the blower motor.

1.

Install reservoir tank, lower radiator hose and air relief plug.

2.

Fill reservoir tank slowly with coolant until coolant spills from the air relief hole. Refer to

CO-62, "Exploded

View"

.

• Put a cloth under the air relief plug to prevent engine coolant to dampen the crankshaft position

sensor.

• Pour coolant to the MAX level line of the reservoir tank at a

rate of 2 liter (1-3/4 lmp qt)/min or lower.

3.

Close the air relief plug.

CAUTION:

If the filling rate is too fast, this could lead to air being
mixed in the coolant. Be sure to fill the coolant slowly
according to the rate indicated above.
Use Nissan Genuine Coolant L250 or equivalent mixed with
water (distilled or demineralised). Refer to

MA-22, "Engine

Coolant Mixture Ratio"

.

4.

Start engine without closing reservoir tank cap and keep engine racing at 1,500 rpm for about 2-3 minutes.
If neccesary, pour engine coolant up to MAX level.
• If coolant overflows reservoir tank hole, install filler cap.
• Watch engine coolant temperature gauge so as not overheat the engine during all of the opera-

tion.

WARNING:

• Be careful not be scaled with hot engine coolant or vacuum pump when operating.
• Radiator fan blade can start at any time and make personal injuries.

5.

Turn off the engine and loose air relief plug until coolant spills from air relief hole.

6.

Close the air relief plug and run the engine at 2,000 rpm until the upper hose comes hot and radiator fan
operates. Let the engine running approximately 5 minutes at idle speed and check for sound of coolant
flow while running engine from idle up to 3,000 rpm.
• Sound may be noticeable at heater water cock.

7.

If sound is heard, bleed air from cooling system by repeating steps 4 to 6 until coolant lever no longer
drops.
• Check the radiator lower hose for any signs of leakage.

8.

Turn off the engine and let it cool down.
• Cool down using a fan to reduce the time.

9.

After cooling period, loose the air relief plug and check if coolant spills from the air relief hole. In other
case, remove the air relief plug until the coolant spills, and then close the relief air plug. Bleed air from
cooling system by repeating steps 6 to 10 until the coolant spills immediately.

10. Check the engine coolant level when engine is cool and refill to MAX level line if the level is lower.

• Clean excess coolant from engine.

11. Check that the reservoir tank cap is tightened.

Flushing

INFOID:0000000001062334

1.

Fill reservoir tank with water until water spills from the air relief hole, then close air relief plug. Reinstall
reservoir tank cap.

2.

Run engine and warm it up to normal operating temperature.

3.

Rev engine two or three times under no-load.

4.

Stop engine and wait until it cools down.

5.

Drain water.

6.

Repeat steps 1 through 5 until clear water begins to drain from radiator.
