How to change antifreeze for a Nissan Tiida. Antifreezes Nissan L248, L250. Analogs and characteristics Branded coolant nissan l250 2

The original antifreeze from the Japanese automaker Nissan is a high quality coolant that has been specially developed for this brand of vehicles. The Belgian company ARTECO produces coolants Nissan. Only Nissan branded coolants are chemically formulated to blend perfectly with Nissan engine cooling systems. At the moment, two antifreezes are popular:

Nissan Coolant L250

Antifreeze Nissan Coolant L250 Premix was originally created for use on all Nissan vehicles. This refrigerant has high technical characteristics, which is confirmed by independent tests and reviews of satisfied consumers.

The replacement period is 6 years or 90,000 km.

Important! This coolant has already been discontinued and was replaced by the Nissan Coolant L248 coolant, which is its full counterpart.

For this reason, according to the manufacturer, L250 can be mixed with L248 without harm to the engine and the car's cooling system, but at the same time the antifreeze replacement period will be reduced to the requirements of L248 - 3 years or 60 thousand km.

Nissan Coolant L248

Antifreeze Nissan Coolant L248 Premix - blue-green antifreeze, made on the basis of ethylene glycol and does not contain ethyl alcohol. The only coolant recommended for use in Nissan vehicles by the manufacturer itself. Among the models of this Japanese brand where this coolant is not recommended for use include such machines as: Kubistar, Primastar, Interstar. It is intended for them special liquid type D.

This antifreeze, according to the manufacturer, has no analogues. It comes in the form of a ready-to-use coolant with freezing points down to -38 ° C, so it can be poured directly into the cooling radiator.

Nissan L248 antifreeze eliminates the possibility of oxidation of engine parts, as well as prevents corrosion, leaks and boil-off. Due to its unique composition, this refrigerant prolongs the service life of the elements of the engine cooling system. In addition, innovative components allow it to be changed less often, and also allow it to be mixed with distilled water in case of emergency.

Advantages and disadvantages

Benefits of Original Nissan Antifreeze:

• Innovative composition;
• Ability to maintain its characteristics over a wide temperature range;
• Special additives present in its composition make it possible to replace the coolant less often than usual;
• Complete inertness to metal and rubber.

Disadvantages of Nissan coolant:

• It is not always possible to buy because of the small volumes of delivery to the stores;
• Relatively high price;
• Comparison with the products of other companies is not always beneficial to this antifreeze.

Liquid for cooling car systems is one of the main components that ensure its smooth operation. Many car owners, and especially beginners, are interested in the questions: which antifreeze should be bought for Nissan, when to replace it and actually how to do it. In this article, we will answer all these questions.

What is a cooling system

To find out why change antifreeze in nissan, it is necessary, first of all, to know what the cooling system is.

The cooling system in Nissan cars performs several very important functions:

in the cold season heats the air inside the car;

thanks to it, the warm-up time of the motor is reduced, which quickly brings the engine into working condition;

exhaust gases are cooled.

Replacing antifreeze

Replace coolant on Nissan for experienced drivers is not difficult, you can also contact a service station. But, if you are a driver with little experience and want to figure it out yourself, then we will give you some useful instructions, following which you can do this procedure in your garage.

But, we want to draw your attention to the fact that before you buy antifreeze in Nissan in a store, you should familiarize yourself with its technical characteristics. So for Qashqai, only red antifreeze from the manufacturer Nissan Coolant L248 premix is ​​suitable.

How and when to replace

Correct and timely replacement of the coolant will ensure the flawless operation of your vehicle. Therefore, try to ensure that its level does not fall below normal.

There are also technical standards for Nissan, namely, to replace the coolant every 90-100 thousand km. mileage, and at the same time use only original coolant.

Make sure the motor is completely cool before starting replacement. Then disconnect all the pipes and, removing the cap from the expansion tank, drain the remains into a container.

Pay attention to dripping liquid. So if it is dark in color or there are any flakes, sediment in it, then it is necessary to thoroughly flush the entire cooling system. It is quite possible to use water for this purpose.

After carrying out all the above procedures, pour antifreeze into expansion tank and start the engine, let it run for a while. Now check the coolant level in the expansion tank and top up to the correct level if necessary.

Basic replacement rules

Summing up, we can say that in general, replacing antifreeze in Nissan cars does not require much work and skills, but you still need to know some rules that should be followed.

Nissan antifreeze is supplied to the market by a Japanese manufacturer. The product belongs to cooling liquids of excellent quality, which are widely consumed and specially designed for auto Nissan... Only branded fluids have a unique chemical composition that is optimally combined with the engine cooling systems installed on the machines of the described brand. There are two types of Nissan antifreeze that are in high demand.

Description Nissan Coolant L250

This type of liquid with a cooling effect was originally produced to equip all Nissan vehicles. A distinctive feature of this refrigerant is high technical characteristics, which is confirmed by numerous consumer reviews verified by independent tests. As for the replacement period, it is 6 years, it is also possible to carry out a change after passing 90 thousand km.

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe me? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!

It is worth knowing that the coolant type Coolant L250 from Nissan is currently discontinued. Previously, it was produced by article numbers:

• KE90299944 - 5 L;
• KE90299934 - 1 l.

The replacement was the developed updated coolant type Coolant L248, which is an analogue of the described product. Due to this feature, refrigerants of the L250 and L248 brands are allowed to be mixed, which will not cause any harm to the vehicle engine. However, when the described compositions are diluted, the replacement period is reduced to 60 thousand km, which is approximately three years of vehicle operation.

L248 Antifreeze Review

This coolant has a blue-green tint, its base is represented by ethylene glycol, and ethyl alcohol is also present in the composition. Coolant L248 is the only refrigerant recommended by the manufacturer for filling Nissan cars. Among Japanese car brands, in which it is not advisable to use the described coolant, the following are highlighted:

• Interstar;
• Primastar;
• Kubistar.

For these models, the original Nissan coolant, belonging to class D, has been developed, which has no analogues in the world. The product is produced in volumes of 5 liters (KE90299945) and 1 liter (KE90299935), with regard to the freezing point, it is 38 ° C. The liquid is completely ready for filling into the automotive system.

Antifreeze grade L248 prevents oxidation processes of individual engine parts, prevents the development of corrosion processes, boil-off, and leaks. Special coolant components extend the service life of the vehicle's cooling system. The presence of innovative components in the composition allows for a rare replacement of the refrigerant, which in extreme conditions can also be diluted with distilled water.

About the advantages and disadvantages

If we talk about original antifreeze Nissan, it has a number of positive and negative indicators, like any other widely consumed automotive product. Of the positive properties, the following are noted:

Of the visible shortcomings, it is noted high price of the described product. The complexity of the acquisition lies in the fact that the original Nissan coolant is supplied to ordinary points of sale in small quantities. It must be purchased from specialized official stores.

To avoid buying a low-quality fake, you must adhere to simple but effective recommendations. It is important to check the liquid for sediment on the bottom. sold containers. Real antifreeze from Nissan is a homogeneous liquid, in which there are no impurities or inclusions. The original packaging is even and without the slightest defects, supplemented with a sticker containing the detailed composition of the product, its article number, date of sale, etc.

Refrigerant replacement

Correct and normal operation of the vehicle is ensured timely replacement coolant. You should not wait for its level to drop to critical indicators, which can lead to a breakdown of the machine. According to technical standards developed for Nissan, the original refrigerant from the manufacturer is replaced after reaching no more than 90 thousand km. mileage.

Allow the motor to cool completely before proceeding with the replacement. After that, all the pipes are disconnected, the cover is removed from the expansion tank, and the remnants of the fluid used are drained. If there is sediment in it, foreign flakes, the cooling system must be thoroughly rinsed. For this purpose, it is used plain water... When all the preparatory procedures have been carried out, the original antifreeze is poured into the expansion tank, the engine starts up, and its correct operation is checked. ... Next, the level of the refrigerant in the working tank is checked., if necessary, it is topped up to the indicated mark.

Features of fluid replacement

Antifreeze in Nissan cars is replaced in the same way as in other vehicles. Special deep knowledge and skills are not required here. However, experts recommend adhering to these rules:

Original coolant from Nissan is a quality and time-tested product. It ensures the smooth and correct operation of the car, contains special additives that warn premature wear individual parts.

Owners Nissan cars who closely monitor their vehicle, probably know about branded antifreezes L248, L250 and L255. Let's figure out what these coolants are.

Branded antifreeze Nissan L248

Coolant L248 Premix antifreeze is specially designed for cars concern Nissan... This product is positioned as a unique coolant developed for cooling systems for trucks and passenger cars Nissan.

However, in fact, apart from the quality and balance of the components, there is nothing extraordinary in L248 antifreezes. They, like most SAE J1034 coolants, are formulated with ethylene glycol, water and a package of organic and inorganic additives. But unlike other coolants, there are no silicate compounds in this antifreeze. This has a positive effect on the intensity of heat removal from the cooling jacket to the coolant due to the formation of a film with a higher thermal conductivity.

The main protective components in L248 antifreeze are phosphate and carboxylate additives. Phosphate protects the walls of the cooling jacket from the aggression of ethylene glycol due to the formation of a thin protective film. But in the event of a lack of fluid in the system, phosphate compounds can cause airing of the circuit. Therefore, among motorists there is such unspoken rule: it is better to top up the expansion tank with water than to drive with insufficient level... Carboxylate compounds block areas of rust and damage growth.

The service life of L248 coolants is limited to 3-4 years. After this time, the protective properties of the additives fall, and the cooling system may begin to deteriorate.

In general, the unspoken analogue of Nissan's antifreezes (or, at least, a product close in characteristics) is the G12 ++ brand antifreeze widespread in the Russian market. It can be poured into the engine cooling systems of Nissasn cars instead of the expensive L248, as well as L250 and L255.

Antifreeze L250 and L255

Antifreeze Nissan L250 (and its later modification L255) is almost completely identical to the L248 product. They are also based on ethylene glycol and water and contain a combined package of organic and inorganic additives. The main differences are in color and durability.

Antifreeze brand L248 has a greenish tint. Due to its less enriched and balanced additive package, it ages slightly faster than other Nissan branded products. Coolants L250 and L255 are blue. Their service life has been increased to 5 years.

In terms of the impact on the cooling system and the intensity of heat dissipation, there is no difference between branded antifreezes for Nissan vehicles.
