Attention:
- Clean the drain plug and screw it in, installing a new O-ring.
- Radiator drain plug. See chapter "Engine lubrication and cooling system".
- If the drain plugs were removed from the drain holes in the cylinder block, screw them in and tighten them. See chapter "Mechanical part of the engine".
2. Make sure the hose clamps are tightened tightly.
3. Remove the air duct and resonator assembly and move the electric throttle actuator to the side. See chapter "Mechanical part of the engine".
4. Disconnect the heater hose (1) in the location indicated by the arrow in the figure.
- Raise the heater hose as high as possible.
5. Fill the radiator (1) to the required level.
Attention. Keep coolant away from non-electronic components (generator, etc.).
- Add coolant slowly at a rate of less than 2 liters. per minute so as to allow the air to escape from the system.
- When coolant begins to flow out of the heater, connect the heater hose and continue refilling.
- Use genuine Nissan coolant or equivalent mixed with water (distilled or desalted). See above.
Engine coolant filling capacity (with tank level «MAX»).
See chapter "Engine lubrication and cooling system".
6. Fill the reservoir with coolant to the mark «MAX».
Filling tank tank (at the level «MAX») *.
See chapter "Engine lubrication and cooling system".
7. Screw the cap on the radiator.
8. Install the electric throttle valve air duct and resonator assembly. See chapter "Mechanical part of the engine".
9. Warm up the engine until the thermostat opens. The standard warm-up time is about 10 minutes at an engine speed of 3000 rpm.
- To determine whether the thermostat is open, touch the lower radiator hose with your hand and make sure that warm liquid flows through it.
Attention: To avoid overheating the engine, watch the coolant temperature gauge.
10. Stop the engine and cool to below 50°C.
- To save time, cool with a fan.
- If necessary, fill the radiator with coolant up to the filler neck.
Attention. Do not allow coolant to come into contact with electronic components (generator, etc.).
11. Fill the reservoir with coolant to the mark «MAX».
12. Repeat paragraphs. Screw the cap on the radiator 5-10 times or more until the coolant level stops dropping.
13. Check for leaks from the cooling system with the engine running.
14. Warm up the engine and check the sound of leaking coolant by increasing the engine speed from idle to 3000 rpm and setting the heater temperature control to several positions between «COOL» and «WARM».
- A sound may be heard from the heater.
15. Repeat step 14 three times.
16. If you hear a sound, bleed air from the cooling system, repeating steps. 5-10 until the coolant level stops dropping.
Flushing the cooling system
1. If removed, install the tank and screw the plug into the radiator drain hole.
Attention:
- Clean the drain plug and screw it in, installing a new O-ring.
- Radiator drain plug: See chapter "Engine lubrication and cooling system".
- If the drain plugs were removed from the drain holes in the cylinder block, screw them in and tighten them. See chapter "Mechanical part of the engine".
2. Remove the air duct and resonator assembly and move the electric throttle actuator to the side. See chapter "Mechanical part of the engine".
3. Disconnect the heater hose (1) in the location indicated by the arrow in the figure.
Raise the heater hose as high as possible.
4. Fill the radiator and reservoir with engine coolant and screw the cap on the radiator.
- When coolant begins to flow out of the heater hose, connect the heater hose and continue refilling.
5. Install the electric throttle valve air duct and resonator assembly. See chapter "Mechanical part of the engine".
6. Start the engine and warm it up to normal operating temperature.
7. Press the accelerator pedal two or three times without load.
8. Stop the engine and wait until it cools down.
9. Drain the system. See above.
10. Repeat pl. 1-9. until clean water starts flowing out of the radiator.
