4. When performing a complete cooling system drain (to remove the engine or for engine repair), remove the

cylinder block front drain plug and the cylinder block RH drain plug.

5. Check the drained coolant for contaminants such as rust, corrosion or discoloration.

• If contaminated, flush the engine cooling system. Refer to "FLUSHING COOLING SYSTEM".

REFILLING ENGINE COOLANT

1. Install the radiator drain plug. If the cooling system was drained completely, install the reservoir tank and

the cylinder block drain plugs.

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

• Apply sealant to the threads of the cylinder block drain plugs. Use Genuine High Performance Thread

Sealant or equivalent. Refer to

2. If disconnected, reattach the upper radiator hose at the engine side.
3. 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.

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-12, "Engine Oil Recommendation"

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.

CAUTION:

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.
12. Fill the cooling system reservoir tank to the specified level and install the radiator cap. Run the engine to

warm up the cooling system and top up the system as necessary.

FLUSHING COOLING SYSTEM

1. Fill the radiator from the filler neck above the radiator upper hose and reservoir tank with clean water and

reinstall radiator filler cap.

2. Run the engine and warm it up to normal operating temperature.
3. Rev the engine two or three times under no-load.
4. Stop the engine and wait until it cools down.
5. Drain the water from the system. Refer to "DRAINING ENGINE COOLANT".
6. Repeat steps 1 through 5 until clear water begins to drain from the radiator.

FUEL LINES
FUEL LINES : Inspection

INFOID:0000000004202058

Inspect fuel lines, filler cap and tank for improper attachment, leaks,

cracks, damage, loose connections, chafing or deterioration.

If necessary, repair or replace damaged parts.

INFOID:0000000004523230

WARNING:

• Be careful not to burn yourself, as the engine oil may be hot.

• Prolonged and repeated contact with used engine oil may cause skin cancer; try to avoid direct skin

contact with used oil. If skin contact is made, wash thoroughly with soap or hand cleaner as soon as

possible.

1. Position the vehicle so it is level on the hoist.
2. Warm up the engine and check for oil leaks from the engine.
3. Stop engine and wait for 10 minutes.
4. Remove the oil pan drain plug and oil filler cap.

CAUTION:

• Be sure to clean the oil pan drain plug and install with a new washer.

• The refill capacity depends on the oil temperature and drain time. Use these specifications for

reference only. Always use the dipstick to determine when the proper amount of oil is in the

engine.

7. Warm up the engine and check around the oil pan drain plug and oil filter for oil leaks.
8. Stop engine and wait for 10 minutes.
9. Check the engine oil level using the dipstick.

CAUTION:

Do not overfill the engine oil.
