Attention:
- Clean the drain plug and screw it in, installing a new O-ring.
- Radiator Drain Plug: See Chapter "Lubrication system and engine cooling system".
If the plugs were removed from the drain holes in the cylinder block, screw them back in and tighten them. See chapter "Mechanical part of the engine".
2. Make sure the hose clamps are tight.
3. Remove the air duct assembly and move the electric throttle actuator to the side. See Chapter "Mechanical part of the engine".
4. Disconnect the heater hose (1) at the location indicated by the arrow.
- Raise the end of the heater hose approximately 100 mm (a) higher than when installed.
5. Fill the radiator (1) to the required level.
Caution: Do not allow coolant to come into contact with electronic components (generator, etc.).
- Pour the coolant slowly at a rate of less than 2 liters per minute to allow air to escape from the system.
- When coolant begins to flow out of the heater hose, reconnect the heater hose and continue filling.
- Use genuine Nissan coolant or equivalent quality mixed with water (distilled or desalted). See above.
Engine coolant filling capacity (with tank at "MAX" level):
See chapter "Lubrication system and engine cooling system".
6. Fill the tank with coolant up to the "MAX" mark.
Tank filling capacity (at "MAX" level):
See chapter "Lubrication system and engine cooling system".
7. Screw the cap back on the radiator.
8. Install the air duct assembly and the electric throttle actuator. 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 if the thermostat is opening, touch the lower radiator hose with your hand and make sure that warm fluid flows through it.
Caution: To avoid overheating the engine, watch the coolant temperature gauge.
10. Stop the engine and cool down to below 50°C.
- To save time, cool with a fan.
- If necessary, fill the radiator with coolant up to the filler neck.
Caution: Do not allow coolant to come into contact with electronic components (generator, etc.).
11. Fill the tank with coolant up to the "MAX" mark.
12. Repeat steps 5-10 two or more times, tightening the radiator cap until the coolant level stops dropping.
13. Check for leaks in the cooling system with the engine running.
14. Warm up the engine and check for leaking coolant by increasing 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 a sound is heard, bleed the cooling system by repeating steps 5-10 until the coolant level stops dropping.
