RECOMMENDED FLUIDS AND LUBRICANTS

For Mexico: Engine Coolant Mixture Ratio

INFOID:0000000005548417

The engine cooling system is filled at the factory with a high-quality,

year-round and extended life engine coolant. The high quality engine

coolant contains the specific solutions effective for the anti-corrosion

and the anti-freeze function. Therefore, additional cooling system

additives are not necessary.

CAUTION:

• When adding or replacing coolant, be sure to use only Genu-

ine NISSAN Engine Coolant.

The use of other types of engine coolant may damage your

cooling system.

• When checking the engine coolant mixture ratio by the coolant

hydrometer, use the chart below to correct your hydrometer read-

ing (specific gravity) according to coolant temperature.

Mixed coolant specific gravity

Unit: specific gravity

WARNING:

Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-

sure fluid escaping from the radiator. Wait until the engine and radiator cool down.

WARNING:

Be sure to perform when the engine is stopped.

1. Remove air duct and resonator assembly when inspecting drive belt. Refer to

EM-26, "Removal and

Installation"

.

2. Visually check entire belt for wear, damage or cracks.

ENGINE COOLANT
ENGINE COOLANT : Changing Engine Coolant

INFOID:0000000005255670

WARNING:

• To avoid being scalded, never change the coolant when the engine is hot.

• Wrap a thick cloth around the cap to carefully remove the cap. First, turn the cap a quarter of a turn

to release any built-up pressure, then push down and turn the cap all the way to remove it.

DRAINING ENGINE COOLANT

1. Turn ignition switch ON and set temperature control lever all the way to HOT position or the highest tem-

perature position. Wait 10 seconds and turn ignition switch OFF.

2. Remove the engine front undercover using power tool.
3. Open the radiator drain plug at the bottom of the radiator, and

remove the reservoir cap. This is the only step required when

partially draining the cooling system (radiator only).

CAUTION:

Do not to allow the coolant to contaminate the drive belts.

ENGINE MAINTENANCE (VQ40DE)

4. When draining all of the coolant in the system for engine

removal or repair, it is necessary to drain the cylinder block.

Remove the cylinder block drain plugs, and block heater if

equipped, to drain the cylinder block as shown.

NOTE:

For Canada, the “D” cylinder block drain plug as shown, is not a

cylinder block drain plug but a block heater.

5. Remove the reservoir tank to drain the engine coolant, then clean the reservoir tank before installing it.
6. Check the drained coolant for contaminants such as rust, corrosion or discoloration.

If the coolant is contaminated, flush the engine cooling system. Refer to

CO-12, "Changing Engine Cool-

ant"

.

REFILLING ENGINE COOLANT

1. Close the radiator drain plug. Install the reservoir tank, cylinder

block drain plugs, and block heater if equipped, if removed for a

total system drain or for engine removal or repair.

• The radiator must be completely empty of coolant and water.

• Apply sealant to the threads of the cylinder block drain plug.

Use Genuine High Performance Thread Sealant or equivalent.

Refer to

GI-14, "Recommended Chemical Products and Seal-

ants"

2. Set the vehicle heater controls to the full HOT and heater ON position. Turn the vehicle ignition ON with

the engine OFF as necessary to activate the heater mode.

3. Remove the vented reservoir cap and replace it with a non-vented reservoir cap before filling the cooling

system.

4. Install the Tool by installing the radiator cap adapter onto the

radiator neck opening. Then attach the gauge body assembly

with the refill tube and the venturi assembly to the radiator cap

adapter.

5. Insert the refill hose into the coolant mixture container that is

placed at floor level. Make sure the ball valve is in the closed

position.

• Use Genuine NISSAN Long Life Anti-freeze coolant or equiva-

lent, mixed 50/50 with distilled water or demineralized water.

Refer to

MA-17, "For North America: Engine Oil Recommen-

dation"

.

6. Install an air hose to the venturi assembly, the air pressure must

be within specification.

CAUTION:

The compressed air supply must be equipped with an air dryer.

7. The vacuum gauge will begin to rise and there will be an audible hissing noise. During this process open

the ball valve on the refill hose slightly. Coolant will be visible rising in the refill hose. Once the refill hose is

full of coolant, close the ball valve. This will purge any air trapped in the refill hose.

8. Continue to draw the vacuum until the gauge reaches 28 inches

of vacuum. The gauge may not reach 28 inches in high altitude

locations, refer to the vacuum specifications based on the alti-

tude above sea level.

9. When the vacuum gauge has reached the specified amount, disconnect the air hose and wait 20 seconds

to see if the system loses any vacuum. If the vacuum level drops, perform any necessary repairs to the

system and repeat steps 6 - 8 to bring the vacuum to the specified amount. Recheck for any leaks.

10. Place the coolant container (with the refill hose inserted) at the same level as the top of the radiator. Then

open the ball valve on the refill hose so the coolant will be drawn up to fill the cooling system. The cooling

system is full when the vacuum gauge reads zero.

Do not allow the coolant container to get too low when filling, to avoid air from being drawn into

the cooling system.

11. Remove the Tool from the radiator neck opening and install the radiator cap.
12. Remove the reservoir cap.
13. Fill the cooling system reservoir tank to the specified level. Run the engine to warm up the cooling system

and top up the system as necessary before installing the reservoir cap.

FLUSHING COOLING SYSTEM

1. Drain the water from the engine cooling system. Refer to

CO-12, "Changing Engine Coolant"

.

2. Fill the radiator and the reservoir tank (to the “MAX” line), with water. Reinstall the radiator cap and leave

the vented reservoir cap off.

3. Run the engine until it reaches normal operating temperature.
4. Press the engine accelerator two or three times under no-load.
5. Stop the engine and wait until it cools down.
6. Drain the water from the engine cooling system. Refer to

CO-12, "Changing Engine Coolant"

.

7. Repeat steps 2 through 6 until clear water begins to drain from the radiator.
