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.

Tools:

1. 7 liters of new fluid Nissan L250. 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. Climb under the bottom of the car. Using a wrench, unscrew all the bolts that secure the protection in the engine.
4. 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.
5. Find and unscrew the drain plugs in the engine block. Wait until all the liquid has flowed out, this takes 15-20 minutes.
6. 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.
7. 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.
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. Close this engine and radiator block with a cover. Using sealant glue, lubricate the hole before closing the block cover.
11. Carefully dismantle the bypass plug.
12. 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.
13. When refrigerant exits this bypass plug, tighten it quickly.
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. Watch the engine to avoid overheating.
16. Turn off the engine and wait for cooling to about 40-50 degrees. You can help the 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. 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 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.

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.

1. So, drive your car into a pit garage or onto a lift.
2. Climb under the bottom and use a wrench to 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 placed a container under it to collect waste consumables.
4. Unscrew the drain plugs on the engine block. Wait about 15-20 minutes for the fluid to drain from the system.
5. 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.
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 harder. The expansion tank should also be filled with water. After that, screw the cap on the radiator.
7. Start the engine and let it idle to allow the engine to warm up to operating temperature.
8. Press the accelerator pedal several times, then stop the engine. Wait until it cools down and repeat the procedure for draining the coolant.
9. 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.
10. Remove the bypass plug.
11. 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.
12. When refrigerant begins to come out of 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 3,000 rpm for 10 seconds. After that, slow down and tighten the plug on the radiator.
14. This procedure should be repeated several times, but make sure that the motor does not overheat.
15. 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.
16. Now check the level of consumables in the expansion tank and, if necessary, add to the radiator up to the neck.
17. Add coolant to the expansion tank up to the MAX mark.
18. 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.

Refueling tanks.

Filling capacity of the engine coolant (with reservoir): ~ 6.7 l.

Tank: 0.7 l.

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

Ready coolant Nissan L250 Coolant Premix:

• 1 Liter KE90299934

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 tank 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.

When buying, you need to know the shade - Color and A type antifreeze, valid for the year of manufacture of your Almera G15. Select the manufacturer of your choice. Do not forget - each type of fluid has its own lifespan.
For instance: for Nissan Almera (Body G15) 2012, with a gasoline or diesel engine type, suitable - lobrid class of antifreeze, type G12 ++ with shades of red. The approximate next replacement period of which will be 7 years. If possible, check the selected fluid against the requirements of the vehicle manufacturer's specifications and service intervals. It's important to know Each type of liquid has its own color. There are rare cases when a type is tinted 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 - can if their types match the blending conditions. G11 can be mixed with G11 analogues G11 must not be mixed with G12 G11 can be mixed with G12+ G11 can be mixed with G12++ G11 can be mixed G13 G12 can be mixed with G12 analogues G12 must not be mixed with G11 G12 can be mixed with G12+ G12 must not be mixed with G12++ G12 must not be mixed with G13 G12+, G12++ and G13 can be mixed together It is not allowed to mix Antifreeze with Antifreeze. No way! Antifreeze and Antifreeze - very different in quality. Antifreeze is the trade name for the traditional type (TL) of an old-style coolant. At the end of the service life - the liquid completely discolors or becomes very dull. Before replacing one type of fluid with another, flush the car radiator with plain water. . Additionally
