Coolant replacement

Coolant drain

Attention.

• To avoid burns, do not change the fluid when the engine is hot.
• Wrap the radiator cap with a thick layer of rags and unscrew the cap. First, turn the plug a quarter of a turn to reduce the pressure in the system. Then turn further and fully open the plug.

1. Disconnect the lower radiator hose and remove the expansion tank cap.

Note. When it is necessary to drain the liquid from the system completely, unscrew the plugs of the cooling system jacket on the cylinder block.

Attention.

• Perform this step only on a cold engine.
• Do not allow coolant to come into contact with the drive belt.

2. If necessary, remove the expansion tank and drain the coolant. Clean the expansion tank before installation.

3. Check the drained coolant for signs of rust, corrosion, or discoloration. If the fluid is contaminated, flush the cooling system.

Coolant filling

1. If removed, install expansion tank.

2. Connect the lower radiator hose.

Note. If the cooling system jacket plugs on the cylinder block have been removed, tighten them to a torque of 9.8 Nm.

3. Tighten all hose clamps securely.

4. Disconnect the heater hose (1) at the location indicated by the black arrow in the figure.

Note.

• The white arrow points towards the front of the vehicle.
• Raise the heater hose as high as possible so that its edge is above the mark "MAX" expansion tank.

5. Fill the expansion tank to the prescribed level:

Fill coolant slowly, no more than 2 liters per minute, to allow air to escape from the system.

When the coolant starts to flow out of the heater block, connect the heater hose and continue to fill the coolant up to the mark "MAX" expansion tank.



Start the engine without closing the expansion tank cap.

Maintaining the crankshaft speed at 1500 rpm for about 2-3 minutes, refuel the expansion tank to the mark "MAX", if needed.

Note. Use Genuine NISSAN Engine Coolant or an equivalent antifreeze/water mixture (distilled or demineralized).

6. Install the expansion tank cap.

7. Warm up the engine until the thermostat opens. Typically, the engine warm-up time at 2000-2500 rpm is 10 minutes.

Note. The opening of the thermostat is indicated by the heating of the lower radiator hose, through which hot coolant begins to flow.

Attention. In order to avoid overheating of the engine, it is necessary to monitor the coolant temperature gauge.

8. Stop the engine and let it cool down to about 50°C.

Note. Turn on the fan to reduce the cooling time.

9. If necessary, add coolant to the expansion tank to the level "MAX".

10. Repeat steps 6 through 9 two or more times with the expansion tank cap installed until the coolant level in the tank no longer drops.

11. With the engine running, check the cooling system for leaks.

12. Warm up the engine and check the sound of coolant flowing with the engine running by changing the engine speed from idle to 3000 rpm and setting the heating temperature control to various positions between "COOL" And "WARM". The sound may be heard in the heater area.

13. Repeat step 12 three times.

14. If the sound is clearly audible, bleed air from the system by repeating steps 6 through 9 until the coolant level stops decreasing.

15. Make sure that the cap of the expansion tank is securely tightened.

Flushing the cooling system

1. Replace the expansion tank (if filmed) and tighten the radiator drain plug.

Attention. Thoroughly clean the radiator drain plug and install with a new O-ring.

2. Disconnect the hose (1) heater at the location indicated by the black arrow in the figure.

Note.

• The white arrow points to the front of the car.
• Raise the heater hose as high as possible so that its edge is above the mark "MAX" expansion tank.

3. Fill the radiator and expansion tank with water and install the radiator cap.

Note. If water starts to flow out through the disconnected heater hose, connect it and continue pouring water further up to the mark "MAX".

4. Install the duct (between air filter housing and electronic throttle actuator).

5. Start and warm up the engine to normal operating temperature.

6. Accelerate the engine to high speeds without load two or three times (on the spot).

7. Stop the engine and wait until it cools down.

8. Drain water from the cooling system.

9. Repeat steps 1 to 8 until clean water flows from the radiator.

10. Make sure that the cap of the expansion tank is securely tightened.
