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 car is a simple but regular action that you will have to do so that your car can live.

Based on the recommendations of the manufacturer Nissan Almera, antifreeze should be replaced every 60,000 km. If the car owner rarely uses the car and drives little, it is advisable to change the coolant every 3 years. After that, replacement can be made less frequently - after 90,000 km. It is forbidden to use antifreeze after the expiration of the mentioned period, because the coolant loses its properties and is not able to fully protect the motor from overheating.

Which antifreeze is better, and how much to pour into a Nissan Almera?

When choosing antifreeze for Nissan Almera, you should focus on the manufacturer's recommendations. All information is available in the instructions for the car. The main requirement is that the antifreeze be of high quality and based on ethylene glycol.

The manufacturer recommends Nissan L250 for the next replacement of antifreeze. This composition provides optimal heat removal from the engine and has a relatively long service life. It contains additives that protect against corrosion, prevent leakage and boiling of the coolant.

Alternatively, the following formulations can be used:

• For cars manufactured between 1995 and 1997, Nissan Almera can be filled with G11 green antifreeze of the following brands - EVOX Extra, Genantin Super, Havoline AFC, AWM, G-Energy NF.
• If the car was produced between 1998 and 2002, it is recommended to fill in class G12 coolant. Suitable types are G-Energy, MOTUL Ultra, Castrol SF, Lukoil Ultra.
• In cars that left the assembly line after 2003 and were produced before 2006, it is advisable to pour G12 + class red antifreeze. Options - MOTUL Ultra, G-Energy, Lukoil Ultra.
• If Nissan Almera was manufactured after 2012, its cooling system requires red G12 ++ antifreeze - Freecor DSC, Castrol Radicool Si, FEBI, VAG.

When replacing antifreeze, you need to stock up on 6.7 liters of coolant (full capacity of the system).

Replacement process

To perform the work, prepare a set of tools. To drain the antifreeze, you will need 7 liters of distilled water, wrenches (it is better to take a set), a container for draining the spent coolant, and also a new antifreeze (7 liters). Also put on gloves on your hands, prepare glue sealant and a clean rag.

Drain antifreeze

The first step in replacing antifreeze on Nissan Almera cars is to drain the old fluid:

1. Remove the motor protection.
2. Discard the bottom tube that is connected to the radiator, then remove the cover.
3. Unscrew the plugs installed in the drain holes of the cylinder block.
4. Remove the coolant reservoir.
5. Look at the condition of the drained antifreeze. Pay attention to the presence of various contaminants such as traces of corrosion, rust and others. Notice the color. If the fluid turns brown, or even black, flush the system.

Flushing the cooling system

The next step is cleaning. Take the following steps:

1. Fill the radiator with water until it flows out of the bypass plug. After that, tighten the plug.
2. Pour distillate into the radiator and tank and screw on the radiator cap.
3. Start the engine and warm it up to the optimum operating temperature.
4. Depress the accelerator pedal 2-3 times, without excessive force.
5. Stop the engine and wait until it cools down.
6. Drain excess liquid.

Pouring new antifreeze

Now the antifreeze is being replaced directly. To fill the system with new antifreeze, do the following:

1. Replace the tank and tighten the plugs that were on the drain holes of the Nissan Almera engine block and radiator.
2. Apply sealant to the threaded part of the drain plug of the engine. Use only quality products.
3. Unscrew the bypass plug.
4. Pour the required amount of antifreeze into the tank and radiator until the required level is reached. Take your time so that the air has time to leave the system.
5. Tighten the plug at the moment when coolant comes out of it.

Start the Nissan Almera engine and wait for it to warm up to normal temperature. First remove the cap from the radiator to let the air out of the system. If, after starting the engine, antifreeze pours out of the neck, return the cap to its place. RPM up to 3000 and hold that level for 10 seconds. After, return the engine to idle. Close the radiator cap and repeat this procedure several times. All the time after starting the engine, watch the temperature gauge to avoid overheating.

In fact, the replacement of antifreeze is completed. Follow a few more steps:

• Stop the engine and let it cool down to 45-50 degrees Celsius. Use a fan to speed up the process.
• Top up coolant if required. Antifreeze should reach the beginning of the radiator neck and up to the MAX mark on the tank.
• Inspect the cooling system - there should be no leaks. Check after starting the engine.
• Warm up the engine, set the temperature control to various positions, and listen for the sounds of antifreeze flowing. If noise is heard, there is still air in the system. Let the engine run with the radiator cap open.
• Wipe the remaining antifreeze from the motor with a rag.

The main questions for the car owner are discussed above - how to drain the antifreeze, what to do to flush the engine, and according to what algorithm to fill the system with a new coolant. If you follow the instructions, you can do the work yourself and avoid visiting the service station.

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.

Coolant (coolant) is of great importance for the proper operation of the car. Thanks to her, the engine does not overheat while driving. Its timely replacement will extend the life of the machine. Replacing the coolant is a simple operation and may well be performed independently. The article describes which antifreeze to fill in Nissan Qashqai and how to properly replace it.

[ Hide ]

We carry out the replacement with our own hands

Due to the formation of a protective film on all surfaces of the cooling system, the coolant protects against corrosion, overheating, and contamination. The coolant is usable as long as anti-corrosion additives are present in it. As soon as their number becomes insufficient, electrolyte corrosion begins. Most of all, aluminum parts and a radiator are exposed to it. Therefore, it is necessary to change the fluid before the onset of corrosion processes.

Nissan Qashqai manufacturers recommend replacing the coolant after 90 thousand mileage or after 6 years of operation to prevent corrosion processes. You can determine the suitability of antifreeze using special test strips. Upon contact with the coolant, they change color: on a special scale, conclusions can be drawn about the state of the antifreeze and the need to replace it.

What kind of antifreeze to fill in?

In Nissan Qashqai, it is better to fill in Nissan branded antifreeze.

It contains anti-corrosion agents and does not require additional additives. You can fill in antifreeze of any brand that meets the G-11 standard. It can be green or blue. According to the rules, it must be diluted with distilled water approximately 50 to 50, in any case, the amount of coolant should be less than 30%. The original Nissan coolant does not require dilution and is ready for use.

Antifreeze that meets the G-12 standard, red or purple, has a longer service life. Manufacturers are constantly working on improving the coolant. A new G-13 standard coolant has appeared on the market, which needs to be changed after 100 thousand mileage. When switching from one standard to another, the cooling system should be cleaned of the previous fluid. In no case should they be mixed, as they lose their anti-corrosion properties.

Tools

You can replace the coolant yourself. Since antifreeze is a very toxic substance, safety precautions should be observed. If liquid gets on the body or car paint, it must be washed off with plenty of water. Near the place where the work will be carried out, there should be no pets and children. To drain the waste liquid, it is necessary to prepare an appropriate container, with a volume of at least 10 liters. Do not pour antifreeze on the ground.

For the replacement procedure, it is necessary to prepare the following materials and tools:

• antifreeze;
• pliers;
• clean rags;
• empty container, with a volume of about 10 liters.

Before work, the car should be installed on a lift, overpass or viewing hole.

Replacement instructions

Antifreeze is changed only on a cold engine. After waiting for the engine to cool down, grab the cap on the expansion tank with a clean rag and turn it counterclockwise.

Expansion tank with cap

When unscrewing, a hissing sound of escaping air should be heard. After the air is released, you need to completely unscrew and remove the cover.

Before draining, remove the protection and splash guards, open all the bleed fittings of the cooling system. The F7R engine has only a radiator bleeder. For other motors, the fittings are on the heating hose. The F3R engine is equipped with an additional bleeder port located on the thermostat housing.

To drain the coolant, the lower pipe is disconnected.

Under the place where it is located, you need to substitute the prepared container. Thanks to good access, it is more convenient to remove the pipe from the adapter tube located in the lower cross member of the body. To remove the branch pipe, loosen the clamp of the outlet pipe by compressing the bent ears with pliers. Then the clamp is moved from the place of attachment.

When the pipe is released from the clamp, it is removed and the waste liquid is drained into the prepared container.

Usually drains about 5 liters. To completely drain the antifreeze on Nissan Qashqai engines, with a volume of 1.4 / 2.0, unscrew the drain plug on the engine.

If there is a lot of rust and contamination in the drained fluid, then the cooling system should be flushed before filling with new fluid. Flushing is also performed in the event of a change in the type of antifreeze. The radiator and engine are washed separately.

To flush the radiator, disconnect the lower and upper radiator hoses. A garden hose is put on the top hose. After connecting the water, the radiator is washed until clean water comes out of the lower hose. If it is not possible to rinse with plain water, a special cleanser is used.

To flush the engine, it is necessary to dismantle the thermostat and temporarily connect the upper hose to the engine. After disconnecting the hoses from the radiator, the top hose is connected to the garden hose and clean water is driven through the engine. Flush the motor until clean water flows from the lower hose. After flushing, the thermostat is installed in place and the hoses are connected to the radiator.

Before pouring new antifreeze into the system, the condition of the hoses should be checked for breaks and cracks, if necessary, replaced with new ones. New antifreeze is poured through the expansion tank. A rag should be placed around the neck. It is necessary to fill in the coolant slowly, excluding the ingress of air into the liquid. To avoid air pockets, the radiator hoses should be periodically pressed with your hands.

Fill coolant up to the maximum mark. Then screw the cap on the expansion tank and start the engine, warming it up to operating temperature. While the engine is running, it is necessary to monitor the temperature of the coolant, avoiding overheating.

If the arrow reaches the red mark, and the radiator fans do not work, you should turn on the heater and check how much air comes out of it. Heated air indicates a malfunction of the fans, cold air - air jams have formed in the system.

Video "Which antifreeze to choose"

This video talks about the types of antifreeze, the myths associated with them, and also gives recommendations for use.

Antifreeze for a car is a special coolant designed to lower the temperature of a car engine. Replacing antifreeze on a car is an important procedure that is recommended for motorists to carry out regularly. This will avoid possible problems with the engine in the future and prevent the development of corrosion inside the cooling system. The publication proposed for consideration will provide information on the features and stages of replacing antifreeze with a Nissan Almera H16 with your own hands, will offer advice on choosing a coolant, and will also list the tools necessary for the procedure. In addition, additional information will be provided on the replacement of antifreeze on car models such as Nissan Almera Classic, Sunny, Expert.

Possible reasons for replacing the coolant

According to auto experts, the need to replace antifreeze with a Nissan Almera N16 arises every 50-60 thousand kilometers of a car run or annually until the mark of 100 thousand kilometers of a car run or five years from the date of operation of the car.

However, in some cases it may be necessary to replace antifreeze on a Nissan Almera H16 car for the following reasons:

• The service life of the coolant has come to an end. In this case, the concentration of inhibitors in the liquid decreases, and thereby the heat transfer decreases;
• The level of the special solution in the tank has decreased. To protect the engine from overheating, you need to monitor the coolant level. In the Nissan Almera H16 expansion tank, it must remain unchanged. Otherwise, a change in the level of antifreeze in the car tank can lead to cracks in the radiator and pipes;
• The coolant level in the Nissan Almera H16 has decreased due to overheating of the car engine. In such a situation, the following happens: the antifreeze begins to boil, which leads to the opening of the valve in the expansion tank of the cooling system and the release of coolant vapor into the atmosphere;
• If the engine is being repaired or parts of the cooling system need to be replaced;
• With frequent operation of the radiator fan during a hot period of time.

Signs that require replacement of antifreeze with a Nissan Almera H16:

• If the color of the coolant has changed or become cloudy, faded;
• According to the results of the test - strips;
• If the measurement of the coolant level in the machine was made using a refractometer or hydrometer;
• If chips, foam, scale, chips are found in the tank.

Every motorist needs to remember the importance of replacing antifreeze. Self-replacement of coolant on a Nissan Almera H16 car is a fairly simple and time-consuming procedure. It is worth remembering that in the event of an untimely change of antifreeze, the liquid loses its properties. As a result, oxides are formed and the risk of overheating of the car engine increases.

Stages of work with the replacement of antifreeze

Before proceeding with the independent replacement of antifreeze with a Nissan Almera H16, it is recommended to carefully select the coolant for the car. For the successful implementation of the procedure, it is advisable to select the original antifreeze or select a high-quality analogue that is suitable specifically for your car model. In order not to encounter an additional problem, it is recommended that you carefully study the composition of the coolant to verify that it complies with international standards.

Before you start replacing antifreeze with any of the Nissan models, be it Almera H16, H15, Nissan Almera Classic, Expert, Sunny, March, Laurel, you need to familiarize yourself with some rules:

• Antifreeze replacement is carried out only with a cooled car engine. Abuse of this rule can lead to serious consequences for your health;
• If the expansion tank of the cooling system is dirty, it must be removed and washed;
• When the car engine is running, it is required to monitor the temperature scale of the coolant. If the arrow is in the red zone, but the fan does not turn on, you should turn on the stove and check how much air comes out. If warm, then the fan has stopped working. If it is cold, then an air lock has appeared in the cooling system;
• It is forbidden to mix cooling solutions for a car of different colors. Before buying a liquid for a Nissan Almera H16, you need to not only study the instructions, but also check the color of the coolant on the car;
• The antifreeze level must be between the minimum and maximum limits;
• Within 3-5 days after replacing the antifreeze, it is recommended to check the level and color of the liquid in the expansion tank. If the level has dropped, you need to add fluid. If the color has changed, the fluid needs to be replaced.

To replace antifreeze in any Nissan model (Almera H 16, H15, Sunny, Expert, Nissan Almera Classic), you need to prepare a list of tools necessary to implement the procedure:

• At least seven liters of antifreeze;
• A free container for draining the used coolant;
• Seven liters of distilled water;
• Rags;
• Spanners;
• Adhesive sealant.

The procedure for replacing antifreeze in Nissan Expert:

• It is required to let the car engine cool down;
• First of all, you need to drain the old solution. To do this, put a free container with a volume of more than seven liters under the radiator;
• To avoid injury, reduce the pressure in the machine's cooling system. To do this, slowly turn the cap of the expansion tank counterclockwise;
• To drain the coolant from the engine, you can use a drain cock or a rubber hose. When draining antifreeze into a Nissan Expert from cylinders, use a drain plug;
• The next step should be flushing the expansion tank. It is recommended not to skip this step, because when flushing the tank, particles of the old solution are removed;
• After closing all drain plugs, it is required to fill in new antifreeze;
• The final step will be to turn on the engine for five to ten minutes. At this time, you should monitor the coolant level in the Nissan Expert. If the level drops, you need to add fluid. Before adding additional fluid, it is necessary to wait for the engine to cool down;
• After completing the procedure, you need to check if there are any leaks.

Step one

The procedure for replacing antifreeze in a Nissan Almera H16 car, as in the case of replacing coolant in other Nissan models, consists in the implementation of three mandatory steps. In order to replace antifreeze at home, you need to study in detail each of the stages.

Draining used antifreeze:

• The first step is to position the car above the pit or lift. This will allow you to easily get to the bottom of the car to drain the liquid;
• Next, you need to unscrew the bolts securing the engine in order to get to the radiator;
• Disconnect the hose from the radiator and remove the cover;
• Unscrew the plugs from the drain holes and wait for the coolant to drain completely. On average, this process takes 15-20 minutes.

step two

The second stage of replacing antifreeze on a Nissan Almera H16 car is not always necessary, but many experts advise not to neglect flushing the engine cooling system. In particular, this should be done if contaminants were found in the old fluid, rust or the color of the solution does not match the original shade.

Flushing the Nissan Almera H16 cooling system:

• Fill the radiator with clean water until water starts to flow out of the plug;
• Close the cap on the radiator and start the engine in order to warm it up to normal temperature;
• Press the pedal three or four times;
• Shut off the car engine and wait for it to cool completely;
• Drain the water.

Step Three

The final step in replacing antifreeze with a Nissan Almera H16 will be filling the car's cooling tank with the appropriate liquid. For the correct implementation of this stage, the following steps should be taken:

• A tank is installed and plugs are unscrewed in the drain holes on the radiator and cylinders;
• Adhesive sealant is applied to the threads of the drain plug of the cylinder block;
• The plug is turned out;
• Slowly pour antifreeze into the radiator and expansion tank of the Nissan Almera H16;
• Close the bypass plug;
• Start the car engine and warm it up to its operating temperature. If the coolant solution spills out of the radiator, tighten the cap;
• Turn off the car and cool the engine to a temperature of at least 50 degrees;
• If necessary, top up the reservoir with coolant to the optimum level;
• Be sure to check for antifreeze leakage while the engine is running.

In general, the process of replacing antifreeze on a Nissan Almera H16 car takes no more than one and a half hours. Subject to the described recommendations and steps, you can easily replace the coolant with a car yourself.
