Nissan car owners who carefully monitor their vehicles, probably know about the corporate antifreeges L248, L250 and L255. Let's discern that these cooling fluids represent.
Corporate antifreeze Nissan L248
Antifreeze COOLANT L248 Premix is \u200b\u200bdesigned specifically for cars of the Nissan concern. This product is positioned as a unique coat, developed under the cooling systems of freight and passenger cars Nissan.
However, in fact, in addition to the quality and balance of components, there is nothing supernatural in L248 antifreeges. They are the same as most of the cooling fluids of the SAE J1034 standard are prepared from ethylene glycol, water and a package of organic and inorganic additives. But unlike other cooling liquids, there are no silicate compounds in this antifreeze. This positively affects the intensity of the heat sink from the cooling shirt to the coolant due to the formation of a film with greater thermal conductivity.
The main protective components in the antifreeze L248 are phosphate and carboxylate additives. Phosphate protected from the aggression of ethylene glycol walls of the cooling shirt due to the formation of a thin protective film. But in the event of a lack of fluid in the system, phosphate compounds may cause the contour delivering. Therefore, among motorists there is such an unlocked rule: it is better to add in expansion tank Waters than ride with insufficient levels. Carboxylate compounds block areas with rapids corrosion and prevent damage growth.
The service life of the cooling fluids L248 is limited to 3-4 years. After this time, the protective properties of additives fall, and the cooling system can begin to collapse.
In general, the unlocked analogue of Nissan antifreeze (or at least close to the characteristics of the product) is a widespread antifreeze of the G12 ++ brand in the Russian market. It can be poured into the cooling systems of the NissaSN motor engine instead of 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 product L248. They are also created on the basis of ethylene glycol and water, have a combined package of organic and inorganic additives in its composition. The main differences are in color and service life.
Antifreeze of the L248 brand has a greenish tint. Because of the less enriched and balanced additive package, it ages somewhat faster than other Nissan branded products. Cooling fluids L250 and L255 painted in blue colour. The service life is increased to 5 years.
In terms of the effect on the cooling system and the heat sink intensity of the difference between the branded antifreezes for Nissan cars.
The original antifreeze from the Japanese automaker Nissan is a high-quality coolant, which was specifically designed for cars of this brand. Produces coolant Nissan Belgian company Arteco. Only Nissan's branded cooling fluids have such a chemical composition that is ideally combined with Nissan Engine Cooling Systems. At the moment, two antifreeze are popular:
Nissan Coolant L250.
GENUINE NISSAN COOLANT L250 5L, 1LAntifreeze Nissan Coolant L250 Premix was originally created for use on all Nissan cars. This refrigerant is high technical characteristicsWhat is confirmed by independent tests and reviews of satisfied consumers.
Replacement period of 6 years or 90,000 km.
Important! This coolant has already been removed from production and the Nissan CoolT L248 coolant was released on its shift, which is its complete analogue.
For this reason, according to the manufacturer, the L250 can be mixed with L248 without damage to the engine and the car cooling system, but at the same time the antifreeze replacement period decreases to the requirements of L248 - 3 years or 60 thousand km.
Nissan Coolant L248.
Original antifreeze Nissan L248 Premix in 5 liters and 1 liter Antifreeze Nissan Coolant L248 Premix is \u200b\u200ba blue-green antifreeze, made on the basis of ethyl glycol and does not contain in its composition of ethyl alcohol. The only coolant, which is recommended for use in the Nissan brand cars by the manufacturer. In the number of models of this Japanese brand where this coolant is not recommended to use such machines as: Kubistar, Primastar, Interstar. For them is intended special fluid Type D.
This antifreeze, according to the manufacturer, has no analogues. It is produced in the form of a finished coolant with a freezing temperature of up to - 38 ° C, so it can be immediately poured into the cooling radiator.
Antifreeze Nissan L248 eliminates the possibility of oxidation of engine parts, as well as prevents corrosion, leakage and bumping. Due to the unique composition, this refrigerant extends the service life of the engine cooling system. In addition, innovative components allow it less frequently change, and also allow it to interfere with distilled water in emergency cases.
Advantages and disadvantages
The advantages of the original Nissan antifreeze:
- Innovative composition;
- The ability to maintain its characteristics in a large temperature range;
- Special additives present in its composition allow you to replace the coolant less frequently than usual;
- Complete inertness to metal and rubber.
Disadvantages of Nissan Co.:
- You can not always buy due to small amounts of delivery to stores;
- Relatively high price;
- Comparison with products of other firms are not always beneficial to this antifreeze.
The car cooling fluid is one of the main components that ensure its work uninterrupted. Many car owners, and especially newbies, are interested in questions: what should the antifreeze should be purchased to Nissan when to replace and actually how to do it. In the article we will answer all these questions.
What is the cooling system
To find out why the antifreeze in Nissan is needed, first of all, to know what is the cooling system.
The cooling system in Nissan cars performs several very important functions:
in the cold season heats the air inside the interior of the machine;
thanks to it, the engine warming time is reduced, which faster leads the engine to the working condition;
the exhaust gases are cooled.
Replacing antifreeze
Replace the coolant on Nissan for experienced drivers is not much difficult, you can also contact the maintenance station. But, if you are a driver with a little experience and want to understand everything yourself, we will give several useful instructions, following which you can make this procedure in your garage.
But, we want to pay attention to that before buying antifreeze in Nissan in the store, you should familiarize yourself with its technical characteristics. So for Qashqai, only antifreeze of the red-colored manufacturer Nissan Coolnt L248 Premix is \u200b\u200bsuitable.
How and when to replace
Proper and timely replacement of coolant will ensure the impeccable work of your vehicle. Therefore, try to keep its level below the norm.
There are also technical standards for Nissan, namely, replacing the coolant every 90-100 thousand km. run, and at the same time use only original liquid For cooling.
Before starting the replacement, make sure the motor is completely cooled. Then disconnect all the nozzles and, removing the cover from the expansion tank, drain the residues into any container.
You should pay attention to the flowing fluid. So if it is dark color or there are any flakes, precipitate, it is necessary to thoroughly rinse the entire cooling system. For this purpose, it is possible to use water.
After all the procedures are held, fill the antifreeze into the expansion tank and start the motor, let it work for a while. Now check the level of the coolant in the expansion tank and, if necessary, decrease to the desired level.
Basic replacement rules
Summing up, we can say that in general, the replacement of antifreeze in cars Nissan. Does not require special work and skills, but it is still necessary to know some rules that should be followed.
Engine Nissan Tiida. In working condition heats up to high thermal values. But for the normal functioning of the car, the temperature in the system should not exceed 90 degrees. Therefore, it is very important to monitor the state of antifreeze, which maintains the temperature regime is normal. Timely replacement This fluid avoids negative consequences.
Stages of replacement of coolant Nissan Tiid
For full replacement Antifreeze will need drain liquid not only from the radiator, but also from the engine block. The benefit of the manufacturer provided for this drain plugs to which in the presence of a pit or lift is not so difficult to get.
This model B. different countries Sold under different names, so the instruction on replacing the coolant is suitable for:
- Nissan Tiida 1 (Nissan Tiida I C11 restyling);
- Nissan Tiida 2 (Nissan Tiida II C13);
- Nissan Latio (Nissan Latio);
- Nissan Versa (Nissan Versa);
- Nissan Pulsar (Nissan Pulsar).
Russia has popular versions with 1.8 engine volume, 1.6 gasoline, as they were sold officially. Although there are versions with 1.5 liters in diesel and gasoline.
Drain of coolant
Before filling a new antifreeze, it is necessary to drain the old one, this procedure is carried out when the engine is cooled. From the tools you will need a stop key to 14, a screwdriver for a cross, passage. Also, at hand, it is necessary to have a rod for wipping and a container for draining liquid with a volume of 10 liters. Due to the toxicness of the coolant when working with it, it is necessary to be careful.
Drain of old antifreeze is performed in the following sequence:
It should be noted that a sealant is applied to the drain bolt. Therefore, when installing it back, do not forget to miss.
After a drain, we set everything into place, now from the cooling system the old antifreeze is removed as much as possible, you can move to the next step.
Flushing cooling system
To new antifreeze He served a long time and did not lose its properties, if there is a mud, scale, rust in the radiator, you need to make the cooling system flushing procedure. If this is not done, the remains of corrosion are mixed with the coolant, and will soon be replaced.
Usually for washing a fairly simple distilled water, which also mentions the manufacturer of cars.
For flushing the cooling system, the Nissan Tiid fill the radiator and the expansion tank with distilled water. We start the engine and wait until it warms up to operating temperature, after which 1-2 minutes increase the speed up to 2500.
Moving motor, we are waiting for its cooling and drain the liquid. The procedure must be repeated several times until the water becomes transparent. After washing in the system there should be no deposits, as well as traces of old antifreeze. This will positively affect the service life of a new antifreeze.
Pouring without air stoppers
The final stage is directly filling a new antifreeze. Before which you need to check the integrity of all pipes, clamps. Damaged details Tone mandatory replacement. Also check for closing all drain holesSo that they are closed. And on the plug of the block head you need to not forget to apply high-temperature sealant.
The fill of the new antifreeze consists of the following steps:
- We find a hose going to the salon stove, remove it. It is done to enter the air so that in the bay, air traffic jams are not formed. This is a complex operation, as the hose itself is in an uncomfortable place, and the clamp is quite hard. After removal, you can replace the clamp on the screw, it will simplify the task. The diameter of the hose is about 27 millimeters.
- Fill up to the maximum mark the expansion tank and slowly begin to pour antifreeze into the radiator. As soon as the liquid is spoiled from the hose, put it in place and fill the radiator to the top of the neck. Close the filler plugs.
- After filling in the system, we put the car, let the engine warm up to the operating temperature, periodically push.
With proper execution, the procedure in the system should not form air traffic jams. This will indicate evenly warm radiator nozzles, upper and lower. As well as a fully working stove.
If the stove blows cold, the load hoses are not evenly, heard the flow of fluid, which means airlock Still formed. To eliminate, in this case, it is necessary in the old manner. Having come back the car on the hill, rebuild your nose. Put on the handbrake and raise the turnover, gas, minutes 3-5.
After a complete replacement, it is not necessary to forget that after cooling the engine you need to check the level of coolant in our Nissan Tiida and, if necessary, add.
Replacement frequency, which antifreeze pour
The first replacement of the coolant in the Nissan Tiid car must be produced in 90 thousand mileage or after 60 months. Subsequent replacements must be made with periodicity of 60 thousand.
Also, in the future, it is necessary to periodically check the quality and level so that in the case of which to detect the leakage of antifreeze in time to immediately eliminate. The refusal to this procedure may entail expensive repair, as well as wear of working parts.
For this car Suitable original antifreeze Nissan Coolant L248 Premix green. When searching for analogs, it is desirable to pick up fluids with Nissan tolerance or in accordance with the documentation for the vehicle.
From the analogues satisfying the requirements are suitable:
- Coolstream jpn;
- Ravenol HJC Hybrid Japanese Coolant Premix.
In the absence of such an opportunity, the use of coolant from third-party manufacturers identical to properties and composition is allowed.

Leaks and problems
When leakage detection, you need to determine the place and on the basis of this to make a decision. If the flow of the nozzle or the problem in the cottage, then you can try to eliminate yourself. And if the problem is more serious, such as leaky anticipation from under the head, then it is better to contact specialized service, To eliminate it.
