Level check
- Make sure the coolant level in the reservoir is between the marks «MIN» and «MAX» when the engine is cold.
A. MAX; B. MIN
- If necessary, bring the coolant level to normal.
Leak check
- To check for leaks, pressurize the cooling system using a pump (suitable special tools) (A) and adapter (suitable special tools) (IN).
Test pressure. See paragraph below. «Technical data and specifications».
Attention:
- Do not remove the radiator cap when the engine is hot. High pressure coolant splashing out of the radiator can cause serious burns.
- Pressure higher than this may cause damage to the radiator.
Note. If the engine coolant level has dropped, add fluid to the radiator.
- If any abnormalities are found, correct them or replace damaged components.
Drain
Attention:
- Do not remove the radiator cap when the engine is hot. High pressure coolant splashing out of the radiator can cause serious burns.
- Wrap the lid with a thick cloth. First, unscrew the cap a quarter turn and release the pressure. Then unscrew the cap all the way.
1. Remove the engine protection from the bottom.
2. Remove the plug (1) from the drain hole at the bottom of the radiator and remove the radiator cap.
Attention. Perform this operation when the engine is cold.
- When draining all the coolant from the system, remove the drain plugs from the drain hole in the cylinder block. See below.
3. If necessary, remove the tank, drain the coolant and clean the tank before installation.
- It is necessary to remove the insulator of the right engine mount. See chapter «Mechanical part of the engine».
- Slide the tank (3) and remove it in the order indicated by the numbers in the figure.
4. Check the drained coolant for contaminants such as rust, corrosion, or discoloration. If there are traces of contamination, flush the engine cooling system. See below.
Refueling
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 below.
- If the drain plugs have been removed from the drain holes in the cylinder block, install and tighten them. See chapter «Mechanical part of the engine».
2. Make sure the hose clamps are tight.
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 place indicated by the arrow (
) in the picture.
- Raise the heater hose as high as possible.
5. Fill the radiator (1) to the required level.
Attention. Do not allow coolant to come into contact with electronic components (generator, etc).
- Add 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, connect the heater hose and continue refilling.
- Use genuine Nissan coolant with antifreeze or equivalent mixed with water (distilled or desalted). See chapter «Maintenance».
Engine coolant filling capacity (with tank level «MAX»):
See paragraph below. «Technical data and specifications»
6. Fill the reservoir with coolant to the mark «MAX».
A. MAX; B. MIN
Tank filling capacity (at level-MAX-):
See paragraph below. «Technical data and specifications».
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 opening, touch the lower radiator hose with your hand and make sure that warm liquid flows through it.
Attention. To avoid overheating the engine, monitor 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. 5-10 times or more, tightening the radiator cap 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 below.
- If the drain plugs have been removed from the drain holes in the cylinder block, install 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 place indicated by the arrow (
) in the picture.
- 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 actuator, 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 pp. 1-9 until clean water starts flowing out of the radiator.
