Antifreeze Nissan L248, L250. Analogues and characteristics

Branded antifreeze Nissan L248

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

However, in fact, apart from the quality and balance of the components, there is nothing super unusual in L248 antifreezes. They, like most coolants of the SAE J1034 standard, are prepared from 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 ones protect 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 the circuit to air. Therefore, among motorists there is such an unspoken rule: it is better to add water to the expansion tank than to drive with an insufficient level. Carboxylate compounds block areas with the beginnings of corrosion and prevent the growth of damage.

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, an 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.

Reviews of motorists

Motorists generally feel good about branded and branded antifreezes, like TCL or FL22 antifreeze. Regarding coolants for Nissan, the owners of these Japanese cars for the most part consider it justified to buy L248 and L250 (L255) antifreezes.

Judging by the reviews, these fluids work perfectly in the cooling system. With timely replacement, overheating, precipitation or premature failure of the pump, thermostat or nozzles are not observed.

Among the disadvantages of L255, L248 and L250 antifreezes, motorists often cite their high price and inaccessibility in remote regions. In some small towns, these coolants can only be purchased on request. At the same time, sellers often make unreasonably high mark-ups.
