Checking the coolant level.
Make sure the coolant level in the reservoir is between the MIN and MAX marks when the engine is cold.
If there is less or more coolant, bring the level to normal!
Draining the coolant.
1. Remove the lower engine protection.
2. Disconnect the bottom hose from the radiator and remove the radiator cap.
3. Turn out stoppers from drain apertures on the block of cylinders.
4. Remove the tank and drain the coolant.
Check the coolant for contaminants such as rust, corrosion and discoloration. If there are traces of contamination, flush the engine cooling system.
Flushing the cooling system.
1. Fill the radiator with water until water flows out of the bypass plug, then tighten the plug.
3. Start the engine and warm it up to normal operating temperature.
4. Press the accelerator pedal two or three times without load.
5. Stop the engine and wait until it cools down.
6. Drain the water.
Filling the engine with coolant.
1. Install the tank, screw the plugs into the drain holes on the radiator and cylinder block.
2. Apply sealant to the threads of the cylinder block drain plug.
3. Use branded sealant or equivalent.
4. Remove the bypass plug.
5. Fill the radiator and reservoir to the required level. Pour in the coolant slowly at a rate of less than 2 liters. per minute to allow air to escape from the system.
6. Tighten the bypass plug when coolant starts to flow out of it.
7. Start the engine and warm it up to normal operating temperature by removing the cap from the radiator. If coolant is pouring out of the radiator filler neck, install the cap.
Let the engine run at 3000 rpm for 10 seconds, then return to idle rpm by screwing the cap on the radiator.
8. Repeat two or three times.
ATTENTION! Watch the coolant temperature gauge so as not to overheat the engine.
9. Stop the engine and cool to below 50°C. To save time, cool with a fan.
If necessary, top up the radiator with coolant up to the filler neck.
11. Check the cooling system for leaks with the engine running.
12. Warm up the engine and check for the sound of leaking coolant by revving the engine from idle to 3000 rpm and setting the heater temperature control to several positions between COOL and WARM.
every 60 thousand km (3 years).
You will need: coolant, a clean rag, a container with a capacity of at least 7 liters for drained coolant, a “14” key.
WARNINGS: Use ethylene glycol based coolants (antifreeze). Change the coolant only when the engine is cold. Coolant is toxic, so be careful when handling it.
When starting the engine, the radiator and expansion tank caps must be closed.
Screw on the radiator cap tightly. The cooling system is under pressure when the engine is running, so if the plug is loosely screwed on, coolant may leak out from under it.
4. Remove the left mudguard of the engine (see "Removal and installation of mudguards of the engine").
3 turns on the drain cock plug and drain the fluid from the radiator.
7. Place a container next to the engine coolant drain hole located on the left side of the cylinder block near the 4th cylinder, unscrew the plug and drain the engine coolant.
8. Replace the engine drain plug.
11. Start the engine and let it run until the electric fan turns on.
12. Stop the engine and drain the water.
13. Flush the cooling system until clean water begins to drain.
14. Fill the engine cooling system by slowly pouring coolant into the radiator to the level of the vapor tube.
15. Start the engine and warm it up to operating temperature (until the fans turn on). As air escapes from the system, add coolant to the radiator.
16. Wrap the radiator cap and add coolant to the expansion tank to the "MAX" mark. Then stop the engine and let it cool down.
17. Check the coolant level and, if necessary, add it to the expansion tank to the “MAX” mark.
NOTE: When the engine is running, watch the coolant temperature on the gauge. If the arrow has reached the red zone, and the radiator fan does not turn on, turn on the heater and check how much air passes through it. If the heater supplies heated air, the fan is most likely defective, and if it supplies cold air, then an air lock has formed in the engine cooling system. To remove it, turn off the engine, let it cool and unscrew the plug of the expansion tank. Start the engine, let it run for 3-5 minutes and tighten the reservoir cap.
If after a very short time the color of the fresh liquid turned brown, then you filled in a fake, in which the manufacturer “forgot” to add corrosion inhibitors. In addition, one of the signs of a fake is a sharp complete discoloration of the liquid. The dye of high-quality coolant is very resistant and only darkens over time. The liquid, tinted with linen blue, is discolored. Such "antifreeze" must be replaced faster.

Many owners know that replacing Nissan Almera Classic antifreeze is one of the preventive maintenance work with the car. It is very important and must be carried out in accordance with all the rules so as not to aggravate the situation of the Nissan Almera N16, G15.
What coolant to use
For all foreign cars, including these, you need to use only high-quality liquid. Still, the use of refrigerants that are based on ethylene glycol is allowed. The specific brand of coolant required should be written in the instructions for your device.
The creators of the Almera 2014 car advise which antifreeze to use, and this is the Nissan L250. This is the original refrigerant that meets all international requirements and ensures long-term operation of your cooling system. This liquid has a green color, although this factor does not affect any of its characteristics.
Try to find exactly this type of product. If the coolant you need is not available at your location, you can order it online or from a dealer. But if you still can’t do it, then try to pick up a similar product.
There are many videos that talk about the coolant. But not all consumables will fit the requirements for this machine. Buy only the original, and if you are not sure, then you should not make a blind purchase.
Fluid replacement
Car developers advise changing it every 60,000 km or once a year. But the very first coolant change should be done after the first 90,000 km of run. The coolant cannot be used after this period in Nissan, since the liquid no longer has the necessary properties, it cannot sufficiently provide the required engine cooling.
Instruments:
- 7 liters of new fluid Nissan L250. It holds 6.7 liters in total.
- Container for collecting unnecessary antifreeze.
- Distilled water, you need 7 liters.
- Spanners.
- Adhesive sealant.
- Rags.
Procedure:
- Before starting, it is worth clarifying that this is a complete replacement of the coolant with the flushing of the cooling system included in it.
- Put the car on a pit or on a lift.
- Climb under the bottom of the car. Using a wrench, unscrew all the bolts that secure the protection in the engine.
- There will be a radiator. Disconnect the pipe from it, which is located lower. Place a container under the radiator to collect the old substance and unscrew the cap of the radiator itself.
- Find and unscrew the drain plugs in the engine block. Wait until all the liquid has flowed out, this takes 15-20 minutes.
- The coolant on the expansion tank must be disconnected in order to drain the substance afterwards. Since this is a complete fluid replacement, the remaining antifreeze must be poured out of the tank.
- We start flushing the system. Start pouring distilled water into the radiator. Fill it up until it goes beyond the bypass plug, and then tighten it harder. Fill the expansion tank with this water. Then return the radiator cap to its place and tighten.
- Activate the engine. Let it idle to warm up the engine to operating temperature.
- Press the accelerometer pedal 2-5 times, then turn off the engine. Wait for it to cool down and repeat the draining process.
- Install the expansion tank in its place. Close this engine and radiator block with a cover. Using sealant glue, lubricate the hole before closing the block cover.
- Carefully dismantle the bypass plug.
- Take a new fluid, pour into the radiator, then into the expansion tank. The pouring process must be carried out slowly. This is done so that air does not get into where we fill it. This means that the air must have time to leave that place so that an air lock does not form.
- When refrigerant exits this bypass plug, tighten it quickly.
- Remove the radiator cap, then start the engine to idle (3000 rpm for 10 seconds). Then reduce the number of revolutions, close the radiator with a stopper.
- Then repeat these steps several times. Watch the engine to avoid overheating.
- Turn off the engine and wait for cooling to about 40-50 degrees. You can help the fan in this matter.
- Check the amount of liquid in the expansion tank, top up if necessary up to the throat.
- Add fluid to the expansion tank at the MAX mark.
- Turn on the engine. Climb under the car, scan the entire system for leaks.
If they nevertheless appeared, then they are easy to find, just for this, the liquid is painted in different colors.
Conclusion
The coolant plays an important role. The reliability and the ability to operate the entire Almer machine depend on it. That is why it is worth choosing a high-quality and original coolant. This is the Nissan L250. It prevents corrosion inside the cooling system, boil-off, leakage of the substance. Remember that replacing antifreeze with a Nissan Almera Classic car is a simple but regular action that you will have to do so that your car can live.
Replacing the coolant (hereinafter referred to as the coolant) in any car is an important part of the technical work. Therefore, the choice of antifreeze should be given special attention, in particular, when it comes to Nissan cars. Today you will learn how the Nissan Almera Classic antifreeze is replaced, what is needed for this and which refrigerant is better to fill.
[ Hide ]
Getting ready to replace
The replacement of consumables includes not only the direct process of technical work, but also preparation. When preparing to change the coolant, you need to know which liquid is better to fill in, how much it is needed, and you also need to prepare everything that can come in handy in the process.
What coolant to pour?
If you do not know which antifreeze to pour into your car, then check out the information provided below. For Nissan Almera Classic cars, as for any other foreign car, it is recommended to use only high-quality antifreeze. It is allowed to use ethylene glycol-based refrigerants, as a rule, the brand of coolant is indicated in the instructions for the vehicle.
The manufacturer recommends pouring the original Nissan L250 refrigerant into their vehicles. As you know, this consumable fully complies with the requirements of Nissan Almera Classic car cooling systems. Its reliability and performance largely depend on the cooling of the power unit of the machine, therefore, the choice of coolant should be approached very carefully and responsibly. Nissan L250 helps prevent corrosion on the inner walls of the components of the cooling system, as well as leaks and boil-off of consumables.
The fluid has been produced in accordance with international standards and is able to provide a long service life for your Nissan's cooling system. The color of the original product is green, but this does not affect the characteristics of the refrigerant.
If you are unable to purchase an original product in your city, then contact the dealer or order it via the Internet. If you can’t do this for some reason, then select analog products that match the specifications of your car.
Note! Today, there are many types of coolants in the domestic car market, but not all of them meet the requirements of Nissan Almera. Refrain from buying if you are not sure that you have an original product.
We carry out a replacement
The manufacturer recommends replacing the consumable every 60,000 kilometers or once a year, whichever comes first. The first coolant change should be made after 90 thousand kilometers. It is strongly not recommended to use the coolant after this period, since the substance loses its properties and is not able to fully cool the engine.
What will be needed?
You will need:
- new antifreeze Nissan L250 in the amount of 7 liters (the system holds 6.7 liters);
- containers for collecting waste consumables;
- 7 liters of distilled water;
- set of wrenches;
- adhesive sealant;
- rag.
Instruction
We will consider the process of completely replacing the coolant, that is, with flushing the cooling system.
- So, drive your car into a pit garage or onto a lift.
- Climb under the bottom and use a wrench to unscrew the bolts securing the engine protection.
- You will see a radiator from which you need to disconnect the lower pipe. Having done this, unscrew the radiator cap, having previously placed a container under it to collect waste consumables.
- Unscrew the drain plugs on the engine block. Wait about 15-20 minutes for the fluid to drain from the system.
- You also need to disconnect and drain the coolant from the expansion tank - some old antifreeze remains in it, but since we are doing a complete replacement of the substance, the coolant tank must be drained.
- Let's start flushing the system. Take distilled water and start pouring it into the radiator. Pour until it starts to come out of the bypass plug, then tighten it harder. The expansion tank should also be filled with water. After that, screw the cap on the radiator.
- Start the engine and let it idle to allow the engine to warm up to operating temperature.
- Press the accelerator pedal several times, then stop the engine. Wait until it cools down and repeat the procedure for draining the coolant.
- Replace the expansion tank and tighten all caps on the engine block and on the radiator. Lubricate the bore with sealant before screwing on the cylinder head cover.
- Remove the bypass plug.
- Take a new original antifreeze and fill it into the radiator and expansion tank to the required level. Consumables should be poured very slowly. This must be done in order to prevent air pockets in the system. If the liquid is poured slowly, the air will have time to leave the system.
- When refrigerant begins to come out of the bypass plug, tighten it.
- Remove the radiator cap and start the engine to idle. Let the engine run at a speed of at least 3,000 rpm for 10 seconds. After that, slow down and tighten the plug on the radiator.
- This procedure should be repeated several times, but make sure that the motor does not overheat.
- Stop the car and wait until the engine cools down to 40-50 degrees. You can turn on the fan to cool it down faster.
- Now check the level of consumables in the expansion tank and, if necessary, add to the radiator up to the neck.
- Add coolant to the expansion tank up to the MAX mark.
- Then start the engine again, crawl under the bottom and check the system for leaks. If they do occur, then they can be identified quickly, because it is for this that the coolant is painted in various colors.
Replacing antifreeze on Nissan vehicles does not differ much from the standard procedure and is subject to the general procedure. If you have technical knowledge and skills, the car owner can perform all the actions on his own, without seeking the help of specialists.
How to replace antifreeze in Nissan Note?
Antifreeze is replaced with a Nissan Note every 3-4 years or at 90-100 thousand kilometers. High-quality and timely filling of new coolant will ensure a stable operating temperature of the engine and reduce the degree of wear of its parts.
To replace antifreeze, you will need a certain equipment:
- pliers and wrenches for unscrewing drain taps and connections;
- gloves and a clean rag;
- a container for draining old antifreeze, as well as flushing fluid and water, is calculated at 5-6 liters at a time;
- consumables - new coolant, flushing and distilled water.
When working with antifreeze, you should pay attention to certain safety rules. After the engine has been running recently, pressure builds up in the system, when opening caps and taps, splashes can get on the hands and face.
Taking into account this factor, it is recommended not only to exercise caution and accuracy when uncorking the system, but also not to work with a hot, just turned off engine. After each warm-up, you should give it time to cool at least to an acceptable temperature.
Separately, the high toxicity of the coolant is emphasized. Antifreeze is poisonous to the environment, gloves should be worn to replace it, and when draining and refilling, make sure that the liquid does not fall on the ground.
How to drain the coolant and flush the cooling system yourself?
Replacing antifreeze with a Nissan Note with your own hands begins with draining the old coolant. If necessary, the system is washed with a special liquid and distilled water. The general procedure is as follows:
- open the radiator and expansion tank caps;
- unscrew the drain cocks of the radiator and cylinder block, having previously placed a container under the drain;
- while the old coolant is flowing out, check the contacts, connections and hoses of the system for corrosion, cracks and leaks, and if they are found, they are replaced;
- about 5 liters should drain from the system, after which the taps are twisted and flushing fluid is poured into the expansion tank;
- the covers are closed, the engine is warmed up to operating temperature;
- after they turn off the engine, let it cool, the liquid is drained in the same order of actions;
- distilled water is poured into the system for flushing, the engine is warmed up in the same way and allowed to cool;
- flushing with water is repeated until it is relatively clean when drained.
It is not recommended to flush the cooling system with filtered water - despite cleaning, minerals remain in it, which settle in the system at high temperatures. The flushing liquid is used once, it is allowed to flush the system without it immediately with distilled water.
The need for flushing is relevant when switching to a new brand of antifreeze, as well as detecting contamination. With a simple coolant update, flushing is not necessary, but experts still recommend completely cleaning the system.
Filling with new fluid
After flushing the system completely and checking the hoses and connections, the system is reset. Antifreeze is poured through the radiator filler neck and expansion tank. The latter has special marks showing the MIN and MAX levels for the coolant.
After pouring antifreeze, the engine warms up again to operating temperature. If, after turning it off, the liquid level in the tank has decreased, top up again to the maximum. Then carefully tighten the caps of the radiator and expansion tank.
A separate procedure concentrate dilution. This solution is not a completely complete antifreeze, it is based only on ethylene glycol and additives and can freeze at a temperature of -10 degrees.
To increase the cooling properties and reduce the freezing threshold, such a concentrate is diluted with distilled water. Its percentage in the resulting solution is adjusted to 30%, an indicator of 50% is considered optimal. Mixing is carried out in a separate container.
In a few days after replacing the antifreeze, its condition is checked again. If the level has dropped, add the required amount. If the color has changed to brown or discolored, the coolant is completely changed.
A change in color indicates a low quality product, the absence of the necessary additives and the presence of useless dyes. High-quality antifreeze does not change color, it can only darken over time.
The difference between changing antifreeze for other Nissan models
- Nissan Note - 2005-08 requires G12+, since 2009 G12++;
- antifreeze replacement for 2001 Nissan X Trail - G12, 2002-08 G12+, since 2009 G12++;
- Nissan Micra before 1989 uses antifreeze, 1990-96 G11, 1997-2001 G12, 2002-08 G12+, since 2009 G12++;
- The Nissan Pathfinder has similar requirements to the Micra, the only difference is that the G12+ has been in use until 2010 and the G12++ since 2013;
- antifreeze replacement in 2003-08 Nissan Teana requires G12+, since 2009 G12++.
The question of how to replace antifreeze with a Nissan Wingroad or Bluebird Sylphy has the same solution as in other models. The procedure is subject to a general procedure, the choice of coolant is also made according to the specified categorization. Specialists do not distinguish individual features or differences in the replacement of antifreeze that distinguish one model from another.
