How to choose and change the coolant in Nissan X-Trail. How to choose and change the cooling fluid in Nissan X-Trail which antifreeze to apply in Nissan X-Trail

The optimal temperature of the internal combustion engine is within 80-90 degrees on the Celsius scale. To maintain this mode, it is necessary to constantly remove the heat from the heated parts. All modern cars are equipped with a liquid cooling system, which includes:

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

Also in the cylinder block and its head there are special holes for which the cooling fluid circulates.

There are two circle of circulation of antifreeze: small and large. The first is designed for rapid heating of the engine and coolant. The second is necessary to cool the antifreeze after passing the full heat exchange cycle.

What is needed cooling fluid (antifreeze)

Previously, many car owners were used instead of antifreeze ordinary water. Such actions were erroneous, since the water has a low boiling point, as a result of which it is formed on the inner walls of the cooling system elements. This leads to a deterioration of heat exchange and, as a result, the rapid wear of the engine parts. To avoid such developing events, it is necessary to use a special cooling fluid.

Nissan Antifreeze Replacement Dates

Many car owners neglect the timely antifreeze replacement procedure, and in vain, because From this, as you have convinced earlier, the operability of the car engine depends. The first replacement of antifreeze in Nissan cars should be carried out after 90 thousand runs, and each subsequent - every 60 thousand. If you postpone this procedure for the future, you can encounter the fact that the coolant will begin to change the properties and adversely affect the metal (usually aluminum), from which the cylinder head is made and the block itself.

Instructions for replacing antifreeze in Nissan cars

For this car brand, the use of the original Nissan antifreeze (based on ethylene glycol) is recommended, which is specified in the documentation for the vehicle. In case there is no possibility to use the original coolant, select analogue based on fluid specifications.

In no case, do not proceed to replace the hot engine, otherwise you can get serious burns.
In addition, use gloves.

The process of replacing the coolant is as follows:

1. Revealing the crane on the radiator, which is accompanied by the leakage of antifreeze.
2. Removing the radiator cover. After that, you will find how the liquid will begin to pour intensely.
3. Removing the lid of the expansion tank.
4. Revealing the cork on the cylinder block.
5. Swinging the cork on the cylinder block.
6. Tightening the crane on the radiator.
7. Filling the cooling system by antifreeze.
8. Filling the expansion tank by antifreeze to the corresponding mark.
9. Spinning of the radiator lid and expansion tank.
10. Engine starting. During his work, we see the testimony of the temperature sensor in the cooling system.
11. The wasting engine and look at the fluid level. The level should be between MIN and MAX marks.

• In order to devastate the expansion tank, you need to remove it. It is done easily: we take the appropriate key and unscrew the bolt on which the tank holds. After removal of the fluid, disconnect the hose and rinse the tank thoroughly and then dry.
• As a rule, after draining antifreeze, there is still some amount of fluid in the system. Throw into a bulk hole in order to drive out the entire cooling fluid.
• After replacing antifreeze, it is recommended to drive a couple of tens of kilometers on the car, then add the required amount of fluid.
• Before filling a new antifreeze, you can rinse the system with ordinary water, or use special compositions.
• Under normal conditions, the boiling point of the antifreeze is 108 degrees Celsius, in the hermetic cooling system 130 degrees Celsius. Therefore, in the event of a tightness impairment (for example, a crack in an expansion tank or hose) the engine will pour the engine. To avoid this, change the expansion tank with the hose in a timely manner.

If you are in doubt that you will conduct an antifreeze replacement procedure yourself, then contact a specialized car service Nissan, where experienced and professional mechanics will solve this task for you.

The antifreeze replacement procedure may seem fairly simple: unscrewed the plug, drained the waste fluid, replacing it with fresh. Alas, not everything is so simple. But, first, let's figure it out, which is a coolant and for which it needs to be changed.

What you need to know about antifreeze

From the title, it can be understood that the coolant is used to remove heat produced by fuel, simply speaking, for cooling internal combustion. Any liquid could cope with this task if she had sufficient specific heat. Nevertheless, in nature there is only one substance with the greatest heat capacity (4200 J / kg ºС) - this is water. It would be ideal for cooling the engines of cars if it were not for one thing: the water is quite an aggressive substance for metals and, moreover, it freezes at a temperature below 0 ºС.

In order to make water suitable for cooling engines in it, substances that prevent its crystallization at low temperatures and special anti-corrosion additives are added. One of these solutions is antifreeze. They are customary to call a solution, ready for filling into the cooling system of the engine. The crystallization temperature depends on the density. By adding concentrated antifreeze into distilled water, you can achieve the necessary density and the required freezing point. But it should not be overly carried away - increasing the density of the coolant, you automatically reduce the specific water heat capacity. In winter, it is not critical, but in the summer of the engine can overheat.

In our latitudes, the cooling fluid can be considered, not freezing at temperatures -35 - -40 ºС. Such antifreeze is sold in the finished form. In regions where frosts can reach -50 ºС, it makes sense to bring the density of "cooled" to 60%. This is 600 g of a concentrate on 1 liter of water. It does not make sense to add more concentrate, since with exceeding this density, the freezing point does not omit, but on the contrary rises. In addition, as indicated above, the specific heat capacity decreases.

Why should I change antifreeze?

During the operation of the car, the coolant aging is aging. Although its density does not change, and there is no risk of crystallization, but the additives are depleted, and the fluid does not provide complete protection against corrosion. The weak link are aluminum parts to which the car radiator belongs. If not changing antifreeze in the timing specified by the manufacturer, sinks and leaks may appear, with all the ensuing consequences. The coolant produces garbage from rust and other products of chemical reactions with metals. It is clear that such a porridge makes it difficult for heat exchange, scoring honeycombs (as a result -).

What antifreeze to apply in Nissan X-Trail?

First Caution: In no case do not pour Tosol to Nissan X-Trail. This liquid is designed to protect copper parts. Aluminum radiator of your SUV does not protect. Tosol designation: TL. Color - blue or shades of blue. Not compatible with all antifreeges of type G.

Second Caution: Remember that not all antifreeze brands are compatible with each other. Therefore, if you do not have compatibility confidence - pour one type of fluid. Each type of antifreeze is marked with its color shade. For example, a green antifreeze type G11 is indicated, and red - G12. These two types of antifreeze are separately suitable for Nissan X-Trail, but it is impossible to mix them. Therefore, when replacing the type of antifreeze to another (incompatible with the previous one), try to merge the maximum amount of coolant (about 7 liters). In this case, be sure to wash the cooling system with water.

Calculate the average repair cost

In the G12 ruler, colorless antifreeze G12 + and G12 ++ can be found. For them, it is permissible mixing with red and green liquids or among themselves. Fill without flushing, if there are no deposits, allowed with compatible types of cooling fluids. This simplifies the replacement process, since the remaining fluid (about 1 - 2 l) will not significantly affect the quality of the cooling.

Cooling systems in gasoline and diesel engine are identical. Therefore, the brands and types of antifreeze used in diesel engines are also suitable for carburetor (injection) engines. Especially for the brand of Nissan cars for sale approved by the manufacturer of this brand of vehicles Antifreeze Nissan Coolant Premix L248 (Ke9029-9935), as well as its concentrate. The liquid of the green color means corresponds to the type G11 (it is impossible to mix with the shades of other colors, but you can mix with the shades of green and yellow or with colorless antifreeges).

Replacement frequency

To the question "" the manufacturer gives a clear answer. The first replacement is recommended to be carried out after 90 thousand km of mileage or after 6 years of its operation, depending on which event comes earlier. All subsequent replacements are performed for every 60 thousand km of mileage. Separate brands declare the development of antifreeze capable of providing mileage to 100 thousand km.

What are the indicators to navigate - to solve you. But it is necessary to control the condition of the coolant before in the winter, using tests:

• The density is measured by the range. To do this, you need to select a small amount of antifreeze from the radiator. This can be done using a rubber pear.
• The state of the additive is determined by the Lacmus, which changes the color, depending on the exhaustion of the composition. Graduation of colors and their meaning are indicated in the instructions.
• In the extreme case, you can go to a hundred and to make sure the suitability of antifreeze.

Replacement frequency for a new car

When buying a new car, any model should be made in the density of antifreeze factory fill. The fact is that the manufacturer can focus on export to countries with a warm climate, and you can't know exactly what car to you. If the concentration is less than 35%, then for our latitudes it must be increased to 40 - 50%. This can be done by adding a compatible concentrate to the factory liquid.

For this, it is not necessary to merge all the antifreeze, and it can be limited to the drain only from the radiator and from the expansion tank. About 1 liter of concentrate and pour back to the radiator should be added to this volume. After warming up the car to the operating temperature, the total ratio of antifreeze and water will reach the desired level.

If you are not sure of compatibility of concentrate, it is better to buy fresh antifreeze and replace the factory fill.

Antifreeze replacement algorithm in Nissan X-Trail

Getting Started with antifreeze replacement procedure, you need to cool the engine if it worked. Make it need not only for their own security reasons. The fill of the cold liquid in the hot block creates a sharp temperature difference, which can lead to unpredictable consequences. This warning is especially relevant in winter.

Consumables:

• antifreeze for the Nissan brand;
• pads for traffic jams;
• sealant.

Instruments:

• sacral turnover;
• key by 14;
• flat screwdriver;
• jack;
• balloon key.

The procedure for draining waste fluid

• Align the pressure by opening the lid of the expansion tank.
• Carefully remove the plastic cork on the radiator with a crossed scold. Then open the radiator cover and collect content into a suitable ass.

• Remove the plastic expansion tank, observing extreme caution in the frost, and empty it. The tank is attached by one bolt to 10.

• For convenient access to the intermediate nozzle, you should remove the left wheel and the protective mudguard.
• Disconnect the scrolling pipe in different directions. If he "baked" and is not amenable, carefully refood the edge of a flat scolder. We drain the liquid from the nozzles.
• To complete the removal of the exhaust antifreeze, you must unscrew the plug on the block. If you shot the wheel, then smooth the jack.
• If you have done everything correctly, then it is from 7 liters of antifreeze. Near the liter will remain in the system, but it is permissible when pouring a compatible coolant.
• Inspect the plugs and contents of the dishes. If dirty impurities are observed in a merge antifreeze - washing with a special means or washing with clean water when replacing the type of antifreeze to another.

We set the details to your places. We change gaskets in the plugs and lubricate them with a sealant for reliability. Pour fresh antifreeze, pressing your fingers on the nozzle for air booming.

After the fill, you need to wait some time until the air bubbles go out. After that, you start the engine when the stove is turned on. If when the operating temperature is reached, the procedure is completed on the cooled engine, topping the antifreeze to the maximum level. Otherwise, you will have to eliminate air traffic jams by pressing on the nozzles.

After a small run, you should monitor the coolant level. If he dropped, then a fraction.

Replacing antifreeze on Nissan Tiida should be timely - it is extremely important for the normal functioning of the power unit on this machine. Some manufacturers claim to be changed liquid (in order to prevent rust, you need once a year).
The engine temperature, which is optimal (for the internal combustion engine), should be located within 80-90 degrees Celsius. To support such a mode, you need to constantly remove the heat from the heated parts.

Causes of refrigeration leaks

Antifreeze in the tank when the engine works, decreases, even when the system is proper. Antifreeze is periodically evaporated, and in winter, when cooling occurs, part of the fluid decreases significantly in volumes. We begin to beat the alarm when antifreeze leaves much faster than it was earlier, that is, with the proper engine operation.

The following problems lead to coolant leakage:

• damage to the expansion tank or its covers;
• damage to tubes and hoses;
• deformation of the radiator.

When such situations arise, the antifreeze evaporates very quickly. In this case, you need to replace the damaged item to the new one. However, if the replacement of antifreeze on Nissan Tiid is quite simple, then the details of the cooling system are more complicated.

How to replace antifreeze on Nissan Tiida?

Many car owners have previously used conventional water instead of antifreeze - these actions are considered erroneous, because water boils at a lower temperature, compared to antifreeze, as a result, a scale was formed on the inner walls of the system elements. As a result, heat exchange was worse and the details of the motor were worse. Especially for these purposes and created a cooling fluid called antifreeze.

Replacing antifreeze on Nissan Tiid models, Nissan Note and Nissan Latio is carried out according to an identical algorithm, since the cooling systems and the location of component parts in the motor compartment coincide. Also on these cars is the same and frequency of replacement of the coolant, because the refrigerant of the G12 + class refrigerant is used.

The first replacement of antifreeze in Nissan Tiida cars should be carried out after 90 thousand mileage or 60 months later. It is also recommended to check the refrigerant every 15 thousand kilometers of a run or 6 months. This procedure is necessary to control the quality of the coolant so that, if necessary, make a premature replacement. Cooling fluid over time loses properties, if you postpone the replacement procedure, it will adversely affect the engine metal and its operation as a whole. After the first replacement of antifreeze, the subsequent times are recommended to change it every 30,000 mileage or 2 kilometers.

Replacing the coolant is carried out in several Stages:

• Draining old refrigerant;
• Flushing cooling system;
• Fill new antifreeze.

Stage First

The draining of old antifreeze is carried out in the following Sequences:

• We unscrew the cork at the bottom of the radiator;
• Remove the radiator lid;
• We merge the coolant.

Stage two

If there are signs of corrosion or scale, it is necessary to wash the cooling system, otherwise the remains of dirt, rust and old liquid will lead to the fact that the new antifreeze will lose its properties very quickly.

The flushing procedure is as follows:

• We pour water into the radiator until you find leak from the plug. After that, closing the plug;
• Tighten the cover in the radiator (in front of this fill the water here);
• We bring the power unit, warm it up to the optimum temperature;
• Smoothly press the gas pedal (several times);
• Stop the operation of the power unit and we are waiting for the water in the system will cool;
• We drag the liquid.

For washing, any suitable liquid is suitable, which is diluted with distilled water. Washing solution can only be used at the first cleaning, subsequent cycles can be poured distilled water. The procedure repeats while the water being drained will not be clean, as a rule, 2-3 times.

Stage Third

After cleaning the cooling system, you need to check the health of all hoses and pipes, and if there is no damage, you can start the fill of the new antifreeze.

The new antifreeze is poured as follows:

• We establish a coolant tank and tighten the plugs on all drainage necks;
• Lubricate all the plugs with sealant;
• Unscrew the bypass valve;
• In the expansion tank, slowly pour antifreeze to the permissible value. It is not worth exceeding the speed of the bay (more than two liters in one minute) to allow air to exit the system;
• We start the power unit, warm it up to the optimal operating temperature, then remove the cap from the radiator;
• The engine is left to work with turns up to 3000 per minute, for 10 seconds, then return to standard and tighten the cover in the radiator;
• Stop the operation of the engine and cool it up to 50 degrees Celsius. Cool fan;
• Refuel the tank to the maximum mark and check the system for the presence of sublishes that occurred during the operation of the power unit;
• The engine is necessary to warm up and check the sounds of the circulating fluid, increasing the revolutions;
• Now you need to wipe the extra antifreeze from the engine and close the hood.

When working with antifreeze, it is recommended to use rubber gloves and not allow it to enter open areas of the skin, as the liquid of poisonous and inflicts chemical burns. If the refrigerant hit his arms or other parts of the body, you need to immediately rinse the affected area with a large number of running water and contact your doctor.

The regular replacement of antifreeze is very important to maintain the optimal operation of the car. Car manufacturers recommend changing antifreeze every 45,000 kilometers to avoid engine overheating. Many mechanics recommend changing antifreeze at least once a year to prevent corrosion formation, especially in vehicles with aluminum cylinder head and radiator. However, this recommendation will soon become obsolete. Antifreeze manufacturers have released a new generation antifreeze market with a formula that, according to manufacturers, makes it possible to increase the timing of antifreeze replacement to 100,000 kilometers. Manufacturers warn that it is necessary to fill a new antifreeze in a clean system. When mixed with conventional antifreeze, the anti-corrosion properties of the new antifreeze are significantly reduced.

The duration of the antifreeze depends on the content of anti-corrosion additives in it, such as silicates, phosphates and borates. While these substances are present in antifreeze, it is not necessary to change it. But as soon as the number of anti-corrosion substances is reduced, the engine and the radiator are subjected to electrolyte corrosion. This is especially dangerous for engines with aluminum parts. With an insufficient number of anti-corrosion substances in antifreeze and suitable conditions, aluminum parts of the engine can quickly turn into a Swiss cheese. That is why antifreeze is better to change before corrosion processes have already begun.

One way to check whether to change antifreeze, it is to test it using special test strips. These strips offer many antifreeze manufacturers. When contacting antifreeze, the strip changes the color by which using a special scale you can determine the state of antifreeze and decide whether to change antifreeze or not.

Replace antifreeze can be independently. To do this, you need to choose a place away from pets and children. Antifreeze is toxic, so working with it, you need to comply with strict security measures. It is impossible to drain antifreeze in rivers and streams, as well as near the sources of water supply (wells, columns, etc.).

Antifreeze is changing on a cold engine. Change antifreeze on the hot engine is dangerous. Find the radiator lid and remove it. Next, locate the drainage of the radiator and open it, pre-putting a large bucket under it. Drain antifreeze. After that, inspect the cooling system hoses for cracks and breaks. If necessary, change the hoses.

Before filling a new antifreeze system need to rinse to remove rust, fat and deposits that can not remove water. To wash the system there are special means for washing. It is necessary to pour the entire bottle of funds into the radiator and add deionized or demineralized water into the radiator and in the tank to the edges. Covers close.

The next step is to turn on the engine and the stove to the maximum and wait until the engine is heated to the operating temperature. After that, you need to turn off the engine and give it to cool, then remove the covers from the radiator and drain the liquid.

After that, it is necessary to pour into the system of ordinary water, close the lids and turn on the engine again for 15 minutes. Then again allow the engine to completely cool and drain the water from the cooling system. Only after that you can pour a new antifreeze.

Pour antifreeze in accordance with the manufacturer's recommendations. The antifreeze concentration in the system should not exceed 70%, and the optimal concentration is 50% antifreeze and 50% water. After filling the antifreeze, you need to turn on the engine and heating in the cabin to the maximum so that the antifreeze is uniformly distributed over the system, as well as to remove air bubbles from the cooling system. After several days of driving the car, do not forget to check the level of antifreeze in the system and the result of antifreeze to the desired level, if necessary.

The replacement of antifreeze on Nissan cars does not have special differences from the standard procedure and is subject to the general procedure. In the presence of technical knowledge and skills, all the actions of the car owner can produce independently, not referring to the help of specialists.

How to replace antifreeze in Nissan Nout?

The replacement of antifreeze to Nissan Note is produced once every 3-4 years or at 90-100 thousand km of run. A high-quality and timely fill of the new coolant will provide a stable engine operating temperature and reduce the degree of wear of its parts.

To replace antifreeze, you will need a certain equipment:

• pliers and keys for unscrewing drain cranes and connections;
• gloves and pure rag;
• capacity for the drain of old antifreeze, as well as washing fluid and water, calculated 5-6 liters at a time;
• consumables - new coolant, flushing and distilled water.

When working with antifreeze, you should pay attention to certain safety regulations. After the recent engine of the engine in the system, pressure is formed, when opening covers and cranes, splashes can get into arms and face.

Taking into account this factor, it is recommended not only to be caution and accuracy when the system is scolding, but also not to work with hot, only the engine is turned off. After each warming, it is necessary to make it time to cool at least to an acceptable temperature.

Separately emphasizes the high toxicity of the coolant. Antifreeze is poisonous for the environment, for its replacement should wear gloves, and when draining and the fill, make sure that the liquid does not fall on the ground.

How to drain the coolant and rinse the cooling system yourself?

The replacement of antifreeze on the Nissan laptop with their own hands begins with the drain of the old coolant. If necessary, the system is washed with a special liquid and distilled water. The overall procedure is as follows:

• open the lids of the radiator and the expansion tank;
• unscrew the drain cranes of the radiator and the block of cylinders, pre-substituting under the drain of the container;
• while the old cooling fluid flows, check the contacts, connections and hoses of the system for corrosion, cracks and leaks, when they are detected, replace;
• from the system, there should be about 5 liters, after that, the taps are spinning and a flushing fluid is poured into the expansion tank;
• covers are closed, the engine warms up to operating temperature;
• after the mois, the motor gives it to cool, the liquid is drained along the same procedure;
• distilled water for flushing is poured into the system, the engine is heated and give it to cool;
• washing with water is repeated until it turns out to be relatively clean.

It is not recommended to wash the cooling system with filtered water - despite the cleaning of it remains minerals, which at high temperatures are settled in the system. Fluid for washing is used once, it is allowed to rinse the system and without it immediately distilled water.

The need for washing is relevant when moving to a new antifreeze brand, as well as discovery of pollution. With a simple renewal of the coolant, the washing is not required, but the specialists are still recommended to fully clean the system.

Pouring a new liquid

After a complete flushing of the system and checking hoses and connections, the system is provided in its original state. Antifreeze is poured through the bulk of the radiator and the expansion tank. The latter has special labels showing MIN and MAX levels for coolant.

After filling the antifreeze, the engine again warms up to the operating temperature. If after it is turned off the level of fluid in the tank decreased - again fill up to the maximum. Then neatly spin the lids of the radiator and the expansion tank.

Separately allocate the procedure dilution of concentrate. This solution is not completely complete antifreeze, it is based only on ethylene glycol and additives and can freeze at 10 degrees.

To increase the cooling properties and reducing the frost threshold, such a concentrate is diluted with distilled water. Its percentage in the resulting solution is adjusted to 30%, an indicator is optimal in 50%. Mixing is produced in a separate container.

A few days later After replacing the antifreeze, its state is checked again. If the level fell - the required amount is attached. If the color has changed to brown or discouraged - completely change the coolant liquid.

Color change speaks of low product quality, the absence of the necessary additives and the availability of useless dyes. High-quality antifreeze does not change color, with time can only darken.

The difference of the change of antifreeze for other models of Nissan

• Nissan Note - 2005-08 requires G12 +, from 2009 G12 ++;
• replacing antifreeze on Nissan X Trail 2001 - G12, 2002-08 G12 +, from 2009 G12 ++;
• Nissan Micra until 1989 uses Tosol, 1990-96 G11, 1997-2001 G12, 2002-08 G12 +, from 2009 G12 ++;
• Nissan Pathfinder has similar requirements from a micra, the only difference is that G12 + is applied until 2010, and G12 ++ from 2013;
• replacing antifreeze in Nissan Teana 2003-08 requires G12 +, from 2009 G12 ++.

The question of how to replace antifreeze to Nissan Wingroad or Bluebird Sylphy, has the same solution as in other models. The procedure is subject to the overall procedure, the choice of coolant is also made by the specified categorization. Separate features or differences in the replacement of antifreeze, distinguishing one model from another, specialists do not allocate.
