Replacing the coolant (hereinafter - coolant) in any car is an important part of 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.

Preparing to replace

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 fluid is best to fill, how much you need, and you also need to prepare everything that may come in handy in the process.

What kind of coolant to pour?

If you do not know what kind of antifreeze to pour into your car, then read the information provided below. For Nissan Almera Classic cars, like for any other foreign car, it is recommended to use only high-quality antifreeze. Operation of refrigerants based on ethylene glycol is allowed, as a rule, the coolant brand is indicated in the instructions for the vehicle.

The manufacturer recommends pouring the original Nissan L250 coolant into their vehicles. As you know, this consumable fully meets the requirements of the cooling systems of Nissan Almera Classic cars. 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 leakage and boil-off of consumables.

The fluids have been produced in accordance with international standards and are 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 in any way.

If you are unable to purchase an original product in your city, then contact a dealer or order it online. If you cannot do this for any reason, then select analogue products that meet the specifications of your car.

Note! To date, 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 if you have original products.

We are replacing

The manufacturer recommends replacing consumables every 60 thousand kilometers or once a year, whichever comes first. The first replacement of the coolant should be done after 90 thousand kilometers. It is strongly not recommended to operate the refrigerant after this period, since the substance loses its properties and is not able to fully cool the engine.

What do you need?

You will need:

• new antifreeze Nissan L250 in the amount of 7 liters (the system holds 6.7 liters);
• container for collecting waste consumables;
• 7 liters of distilled water;
• set of wrenches;
• adhesive sealant;
• rags.

Instructions

We will consider the process of completely replacing the coolant, that is, flushing the cooling system.

1. So, drive your car into a pit garage or lift.
2. Climb under the bottom and using a wrench, unscrew the bolts securing the engine protection.
3. You will see a radiator from which you need to disconnect the lower pipe. Having done this, unscrew the radiator cap, having previously substituted a container under it to collect the used consumables.
4. Unscrew the drain plugs on the engine block. Wait about 15-20 minutes for the liquid to drain from the system.
5. You also need to disconnect and drain the coolant from the expansion tank - some of the old antifreeze remains in it, but since we are carrying out a complete replacement of the substance, you need to drain the coolant from the coolant tank.
6. 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 firmly. The expansion tank should also be filled with water. Then screw the cap onto the radiator.
7. Start the engine and let it idle to warm up the engine to operating temperature.
8. Press the accelerator pedal several times, then turn off the engine. Wait until it cools down and repeat the coolant drain procedure.
9. Replace the expansion tank and tighten all caps on the engine block and radiator. Before screwing on the cover of the cylinder block, grease the hole with sealed glue.
10. Remove the bypass plug.
11. Take a new original antifreeze and pour it into the radiator and expansion tank to the required level. The consumable should be filled very slowly. This must be done in order to prevent air locks in the system. If the fluid is poured slowly, air will escape from the system.
12. When refrigerant starts to escape from the bypass plug, tighten it.
13. Remove the radiator cap and start the engine to idle. Let the engine run at a speed of at least 3 thousand per minute for 10 seconds. After that, slow down and tighten the plug on the radiator.
14. This procedure should be repeated several times, but be careful not to overheat the motor.
15. Stop the car and wait until the engine has cooled down to 40-50 degrees. You can turn on the fan to cool it down faster.
16. Now check the level of consumables in the expansion tank and, if necessary, add to the radiator to the very neck.
17. Add coolant to the expansion tank up to the MAX mark.
18. Then start the engine again, climb under the bottom and check the system for leaks. If they occur, then they can be identified quickly, because it is for this that the coolant is painted in different colors.

Refueling tanks.

Engine coolant filling capacity (with reservoir): ~ 6.7 l.

Tank: 0.7 l.

Antifreeze: in the original packaging from NISSAN comes Castrol Antifreeze NF.

Ready coolant Nissan L250 Coolant Premix:

• 1 Liter KE90299934

• 5 Liters KE90299944

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, top up the level!

Draining the coolant.

1. Remove the lower engine guard.

2. Disconnect the lower hose from the radiator and remove the radiator cap.

3. Remove the drain plugs from the cylinder block.

4. Remove the reservoir 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 it flows out of the bypass plug, then tighten the plug.

3. Start the engine and warm it up to normal operating temperature.

4. Depress the accelerator pedal two to 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 reservoir, screw the plugs into the drain holes on the radiator and cylinder block.

2. Apply sealant to the threads on the drain plug on the cylinder block.

3. Use a proprietary sealant or equivalent.

4. Unscrew the bypass plug.

5. Fill the radiator and reservoir to the required level. Add coolant slowly at a rate of less than 2 liters. per minute so as to allow air to escape from the system.

6. Tighten the bypass plug when coolant begins to flow out.

7. Start the engine and warm it up to normal operating temperature by removing the radiator cap. If coolant is pouring out of the radiator filler neck, replace the cap.

Let the engine run at 3000 rpm for 10 seconds, then return to rpm by tightening the cap on the radiator.

8. Repeat two to three times.

ATTENTION! Observe the coolant temperature gauge so as not to overheat the engine.

9. Stop the engine and cool to below 50 ° C. Cool with a fan to save time.

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 flowing coolant by increasing the engine speed from idle to 3000 rpm and setting the heater temperature control to several positions between COOL and WARM.

The optimum temperature for an internal combustion engine is between 80-90 degrees Celsius. To maintain this mode, it is necessary to constantly remove heat from heated parts. All modern cars are equipped with a liquid cooling system, which includes:

• main radiator,
• radiator for oil cooling,
• forced cooling fan,
• pump for pumping liquid,
• thermostat,
• expansion tank,
• connecting pipes,
• temperature sensor.

Also in the cylinder block and its head there are special holes through which the coolant circulates.

There are two circles of antifreeze circulation: small and large. The first is designed to quickly heat up the engine and coolant. The second is necessary to cool the antifreeze after it has passed a full heat exchange cycle.

What is coolant (antifreeze) for

In the past, many car owners used regular water instead of antifreeze. Such actions were erroneous, since the water has a low boiling point, as a result of which scale forms on the inner walls of the cooling system elements. This leads to a deterioration in heat transfer and, as a result, rapid wear of engine parts. To avoid such a development of events, it is necessary to use a special coolant.

Nissan antifreeze replacement timing

Many car owners neglect the timely procedure for replacing antifreeze, but in vain, because from this, as you have seen earlier, the performance of the car engine depends. The first replacement of antifreeze in Nissan cars should be carried out after 90 thousand mileage, and each subsequent replacement - every 60 thousand. If you postpone this procedure for the future, you may be faced with the fact that the coolant will begin to change its properties and negatively affect the metal (usually aluminum) from which the cylinder head and the block itself are made.

Instructions for replacing antifreeze in Nissan vehicles

For this car brand, it is recommended to use original Nissan antifreeze (based on ethylene glycol), which is specified in the documentation for the vehicle. If it is not possible to use the original coolant, select an analogue based on the specifications of the fluid.

Do not under any circumstances start replacing with a hot engine, otherwise you can get serious burns.
Also, use gloves.

The coolant replacement process is as follows:

1. Unscrewing the tap on the radiator, which is accompanied by the leakage of antifreeze.
2. Removing the radiator cap. After that, you will find how the liquid begins to pour out more intensively.
3. Removing the expansion tank cap.
4. Unscrewing the plug on the cylinder block.
5. Tightening the plug on the cylinder block.
6. Tightening the tap on the radiator.
7. Filling the cooling system with antifreeze.
8. Fill the expansion tank with antifreeze to the appropriate mark.
9. Tightening the radiator cap and expansion tank.
10. Engine starting. During its operation, we observe the readings of the temperature sensor in the cooling system.
11. We turn off the engine and look at the liquid level indicator. The level should be between the MIN and MAX marks.

• In order to empty the expansion tank, you need to remove it. This is done easily: we take a suitable wrench and unscrew the bolt that holds the tank. After removing the liquid, disconnect the hose and thoroughly rinse the tank and then dry it.
• As a rule, after draining the antifreeze, some liquid remains in the system. Blow into the filler hole to expel all the coolant.
• After replacing antifreeze, it is recommended to drive a couple of tens of kilometers by car, and then add the required amount of fluid.
• Before pouring new antifreeze, you can flush the system with plain water, or use special compounds.
• Under normal conditions, the boiling point of antifreeze is 108 degrees Celsius, in a sealed cooling system 130 degrees Celsius. Therefore, in the event of a leakage (for example, a crack has formed in the expansion tank or hose), the engine will boil. To avoid this, change the expansion tank with a hose in a timely manner.

If you doubt that you will carry out the antifreeze replacement procedure yourself, then contact a specialized Nissan car service, where experienced and professional mechanics will solve this problem for you.

Many owners know that replacing the Nissan Almera Classic antifreeze is one of the preventive maintenance work with the car. It is very important and must be complied with in accordance with all the rules so as not to aggravate the situation for Nissan Almera N16, G15.

What coolant to use

For all foreign machines, 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 coolant grade 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 an original refrigerant that meets all international requirements and ensures long-term operation of your cooling system. This liquid is green, although this factor does not affect any of its characteristics.

Try to find this particular type of product. If the required coolant is not available in your place of residence, you can order it online or from a dealer. But if you still fail to do this, then try to find a similar product.

There are many videos about 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 change

Car developers advise changing it every 60,000 km or once a year. But the very first coolant change must be done after the first 90,000 km. The refrigerant cannot be used after this period in Nissan, since the liquid no longer has the required properties, cannot sufficiently provide the required engine cooling.

Tools:

1. 7 liters of new Nissan L250 fluid. It holds 6.7 liters in total.
2. Container for collecting unnecessary antifreeze.
3. Distilled water, you need 7 liters.
4. Spanners.
5. Adhesive sealant.
6. Rags.

Procedure:

1. 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.
2. Put the car on a pit or on a lift.
3. Get under the bottom of the car. Using a wrench, unscrew all the bolts that secure the protection to the engine.
4. There will be a radiator. Disconnect the lower branch pipe from it. Place a container under the radiator to collect the old substance and unscrew the cap of the radiator itself.
5. Find and remove the drain plugs in the engine block. Wait until all the liquid has drained out, this takes 15–20 minutes.
6. The refrigerant on the expansion tank must be disconnected in order to drain the substance afterwards. Since this is a complete fluid replacement, it is imperative to pour out the remaining antifreeze from the tank.
7. We start flushing the system. Start pouring distilled water into the radiator. Fill it until it extends beyond the bypass plug, and then tighten it harder. Fill the expansion tank with this water. Then put the radiator cover back in place and screw it on.
8. Activate the engine. Let it idle to warm up the engine to operating temperature.
9. Press the accelerometer pedal 2–5 times, then turn off the engine. Wait for it to cool down and repeat the draining process.
10. Install the expansion tank in its place. Place a cover on this engine and radiator block. Using sealed adhesive, lubricate the hole until the unit cover is closed.
11. Carefully remove the bypass plug.
12. Take a new fluid, pour it into the radiator, then into the expansion tank. The pouring process should be carried out slowly. This is done so that air does not enter where we pour. This means that the air must have time to leave the place so that an air lock does not form.
13. Retighten the bypass plug quickly when refrigerant escapes from this bypass plug.
14. 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.
15. Then repeat these steps several times. Observe the motor to avoid overheating.
16. Turn off the engine and wait for cooling down to about 40-50 degrees. You can help a fan in this matter.
17. Check the amount of liquid in the expansion tank, top up, if necessary, up to the throat.
18. Add fluid to the expansion tank at the MAX mark.
19. Switch on the engine. Climb under the vehicle, inspect the entire system for leaks.

If they did appear, then they are easy to find, just for this, the liquid is painted in different colors.

Conclusion

The coolant plays an important role. Reliability and the ability to operate the entire Almera 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, and substance leakage. Remember that replacing antifreeze on a Nissan Almera Classic car is a simple, but regular action that you will have to do in order for your car to live.

Antifreeze for Nissan Almera G15

When buying, you need to know the shade - Colour and A type antifreeze approved for the year of manufacture of your Almera G15. Select the manufacturer at your discretion. Do not forget - each type of fluid has its own service life.
For instance: for Nissan Almera (Body G15) 2012 onwards, with a gasoline or diesel engine type, lobrid antifreeze class, type G12 ++ with shades of red is suitable. The approximate next replacement period is 7 years. If possible, check the selected fluid against the vehicle manufacturer's specifications and service intervals. It is important to know Each type of liquid has its own color. There are rare cases when a type is colored with a different color.
The color of red antifreeze can be from purple to light pink (green and yellow have the same principles).
Mix liquid from different manufacturers - canif their types match the mixing conditions. G11 can be mixed with G11 analogues G11 cannot be mixed with G12 G11 can be mixed G12 + G11 can be mixed G12 ++ G11 can be mixed G13 G12 can be mixed with G12 analogues G12 cannot be mixed with G11 G12 can be mixed with G12 + G12 cannot be mixed with G12 ++ G12 cannot be mixed with G13 G12 +, G12 ++ and G13 can be mixed with each other Mixing of Antifreeze with Antifreeze is not allowed. No way! Antifreeze and Antifreeze are very different in quality. Antifreeze is the trade name of the traditional type (TL) of the old-style coolant. At the end of its service life, the liquid is completely discolored or very dull. Before changing one type of fluid to another, flush the car radiator with plain water. ... Additionally
