Original antifreeze Nissan Coolant L248 Premix is a specialized coolant developed by the company’s engineers for the concern’s modern engines. Unlike universal analogues, this product takes into account the features of car cooling systems Nissan, Infiniti And Renault (within the alliance). Its unique formula is based on ethylene glycol with a package of organic additives OAT (Organic Acid Technology) provides an extended service life of up to 5 years or 160,000 km - subject to compliance with maintenance regulations.

Many owners are faced with a dilemma: to buy a branded L248 Premix at a price 2-3 times higher than universal analogues or take a chance with alternative liquids. In this article we will look at chemical composition antifreeze, its compatibility with specific models (including Qashqai J11, X-Trail T32 And Navara D23), and we will also give step-by-step instructions for replacement, taking into account the nuances of the design of cooling systems Nissan. We will pay special attention to common mistakes that reduce the life of the liquid by 30-40%.

Technical specifications Nissan Coolant L248 Premix

Antifreeze L248 Premix belongs to the class carboxylate coolants (OAT) with low silicate content. Its key parameters are regulated by an internal standard Nissan KE902-99932:

  • 🔹 Main component: monoethylene glycol (concentration 95%+)
  • 🔹 Color: blue (official name - Nissan Blue), does not change during operation
  • 🔹 Freezing point: up to -37°C (ready)
  • 🔹 Boiling point: 130°C (at 1.1 bar pressure)
  • 🔹 Service life: 5 years or 160,000 km (whichever comes first)

Important note: L248 Premix is supplied as a ready-made solution (premix) that does not require dilution with water. The concentration of ethylene glycol has already been optimized for the climatic conditions of Europe and Asia. Unlike concentrates (eg. Nissan Coolant L250), this product eliminates the risk of mismixing with water, which is critical for aluminum cylinder blocks in modern engines HR16DE or MR20DD.

Parameter Meaning Note
Density at 20°C 1.072–1.078 g/cm³ Measured by hydrometer
pH balance 7.5–8.5 Alkaline environment for corrosion protection
Seal Compatibility EPDM, silicone, fluorine rubber Not aggressive to rubber pipes
Quality standard JIS K 2234, Nissan KE902-99932 Meets Japanese and domestic requirements
⚠️ Attention: Antifreeze L248 Premix incompatible with propylene glycol based fluids (e.g. Toyota Super Long Life Coolant). Mixing causes sediment to form, which clogs the radiator channels and thermostat. When switching from another type of antifreeze, flushing the system is mandatory!

Compatible with Nissan, Infiniti and Renault models

The manufacturer positions L248 Premix as a universal solution for most alliance vehicles produced after 2010. However, there are nuances depending on the type of engine and radiator material. Below is the compatibility table for key models:

  • 🚗 Nissan Qashqai J11/J11B (2014–present) - all petrol and diesel versions
  • 🚗 Nissan X-Trail T32 (2014–present) - except for hybrid modifications (required L255)
  • 🚗 Nissan Navara D23 (2015–present) - only with engines YD25DDTi And YD23DDT
  • 🚗 Infiniti QX50 (2019–present) — with engine VC-Turbo (KR20DDET)
  • 🚗 Renault Koleos II (2016–present) - only for European and Asian markets

For vehicles with aluminum radiators (e.g. Nissan Juke F15 or Nissan Leaf) use L248 mandatory - silicate antifreeze (such as G11) cause corrosion of the alloy. At the same time, for older models with cast iron blocks (for example, Nissan Patrol Y61 with engine TD42) cheaper analogues of the class are also suitable G12+.

Differences between L248 Premix and other Nissan antifreezes

Company Nissan produces several types of coolants, which often causes confusion. Main differences L248 Premix from other products in the line:

  1. L248 Premix — ready-to-use solution (does not require dilution), blue in color, for modern engines with aluminum components.
  2. L250 — concentrate (requires mixing with distilled water in a ratio of 50/50), green, compatible with L248 when properly diluted.
  3. L255 - specialized fluid for hybrid and electric vehicles (for example, Nissan e-Power), purple color, service life up to 8 years.

Critical difference L248 from universal class antifreezes G12++ — availability of additive package Nissan Long Life Additive, which prevents the formation of gel deposits in the channels of the cooling system. This is especially important for turbocharged engines (e.g. MR16DDT in Nissan Juke Nismo), where overheating is critical for the life of the turbine.

What happens if you mix L248 with G11?

Mixing carboxylate (L248) and silicate (G11) antifreeze leads to a chemical reaction that results in the formation of abrasive particles. They act as “sandpaper” for the pump and thermostat, reducing their service life by 40–60%. In addition, silicates from G11 settle on the hot surfaces of aluminum cylinder heads, reducing heat transfer by 15–20%.

Step-by-step instructions for replacing antifreeze

Replacing coolant in cars Nissan has features related to the design of the cooling system. For example, in Qashqai J11 The drain valve is located on the lower radiator pipe, and in X-Trail T32 - on the cylinder block. To work you will need:

  • 🔧 Set of sockets and 10 mm wrench (for drain plugs)
  • 🔧 Funnel with an extended spout (for pouring without spills)
  • 🔧 Container for old antifreeze (volume of at least 8 liters)
  • 🔧 Distilled water (10–15 liters for rinsing)
  • 🔧 Vacuum pump (optional, for complete air removal)

Replacement algorithm (for example Nissan Qashqai J11 2.0):

1. Drain the old fluid (open the valve on the radiator and the plug on the block)

2. Rinse the system with distilled water (3–5 cycles)

3. Close the drain holes and fill with new L248 Premix

4. Warm up the engine to 90°C with the expansion tank cap open

5. Add antifreeze to the MAX level after cooling-->

Key point - air removal from the system. On models with an electronic thermostat (e.g. X-Trail T32) air pockets can cause false errors P0128 (insufficient coolant temperature). For pumping:

  1. Start the engine and let it idle for 2-3 minutes.
  2. Smoothly increase the speed to 2500-3000 rpm and hold for 10-15 seconds.
  3. Repeat the procedure 3-4 times, checking the level in the expansion tank.
⚠️ Attention: In engines VR30DDTT (for example, in Infiniti Q50) a dual-circuit cooling system is used. When replacing antifreeze, it is necessary to pour the liquid into both expansion tank (main and additional for the turbine)!

Common replacement errors and their consequences

According to statistics from service centers, 65% of premature failures of pumps and radiators are associated with improper replacement of antifreeze. Common mistakes:

  • 🚫 Using tap water for dilution (leads to the formation of scale on the walls of the channels).
  • 🚫 Incomplete drainage of old fluid (residues G11 or G12 react with L248 to form flocs).
  • 🚫 Ignoring flushing when switching from another type of antifreeze (risk of blockage of the heater radiator).
  • 🚫 Overflow above the MAX mark (when heated, excess liquid is squeezed out through the tank lid).

One of the most dangerous mistakes is replacing antifreeze without checking the system for leaks. For example, in Nissan Navara D23 with engine YD25DDTi A thermostat gasket leak may go undetected unless a pressure test is performed. For diagnostics use pressure blower (optimal value is 1.2 bar). The leak will appear in 5–10 minutes.

💡

Before adding new antifreeze, check the condition of the expansion tank. Microcracks (especially in welds) often cause a gradual drop in the liquid level. B Nissan Almera Tino tanks with article number 21450-4M000 prone to cracking after 5 years of use.

Analogues of Nissan Coolant L248 Premix: what can be filled instead of the original

Cost of original antifreeze L248 Premix (article KE902-99932) is ~1500–2000 rubles per 5 liters, which encourages owners to look for alternatives. However, not all analogues are compatible. Selection criterion - compliance with the standard JIS K 2234 and the absence of silicates. Suitable options:

Brand Title Article Notes
Ravenol JC Coolant Premix 4014835755806 Complete analogue in composition, approved for Nissan And Infiniti
Motul Inugel Optimal 105770 Suitable for aluminum radiators, service life 5 years
CoolStream Premium CS010-005 Budget option, but requires replacement every 3 years

Important: even among approved analogues there are nuances. For example, Ravenol JC Coolant has a higher boiling point (135°C versus 130°C for L248), which is useful for tuned engines. But CoolStream Premium contains fewer corrosion inhibitors and is therefore not recommended for vehicles with mileage over 100,000 km.

⚠️ Attention: On models with system Eco Mode (For example, Nissan Altima L33) the use of non-original antifreeze can lead to false operation of the temperature sensor. This is due to a different thermal conductivity coefficient of the liquid, which affects the operation algorithms of the ECU.

Owner reviews and expert opinion

Analysis of reviews on forums (for example, Nissan Club Russia or Drive2) shows that 87% of owners using L248 Premix, do not encounter cooling system problems during the warranty period. Among the common complaints:

  • ❌ High price (2-3 times more expensive than universal G12++).
  • ❌ Difficulties with purchasing in the regions (counterfeits are common).
  • ✅ No sedimentation even after 5 years of operation.
  • ✅ Stable operation of the thermostat (no temperature fluctuation).

Autochemical laboratory experts ATC Russia carried out tests that showed that L248 Premix superior to analogues in two key parameters:

  1. Oxidation resistance: after 500 hours of testing, no traces of additive decomposition were found in the liquid.
  2. Cavitation protection: microbubbles that destroy the metal do not form on the walls of the liners (relevant for diesel engines YD25).

Interesting fact: in Japan there is antifreeze L248 even used in racing versions Nissan GT-R (model R35), where the thermal load on the cooling system is 3–4 times higher than in civilian vehicles. This indirectly confirms its high performance properties.

💡

The original Nissan Coolant L248 Premix is the only fluid that guarantees the preservation of factory heat transfer parameters in engines with a variable compression system (for example, VC-Turbo in Infiniti QX50).

FAQ: Frequently asked questions about Nissan Coolant L248 Premix

Can L248 Premix be mixed with distilled water?

No, L248 Premix - This is a ready-made solution that does not require dilution. You can add water only in emergency cases (for example, if there is a leak on the way), but then the system needs to be flushed and fresh antifreeze added. The optimal concentration of ethylene glycol has already been selected by the manufacturer for the climatic zones of Europe and Asia.

How to distinguish the original L248 from a fake?

Signs of the original:

  • 🔍 Canister with a holographic sticker and production date.
  • 🔍 Label with article number KE902-99932 and a barcode starting with 490.
  • 🔍 The color of the liquid is rich blue without turbidity.
  • 🔍 There is no sediment at the bottom of the canister (shake before purchasing).

Counterfeits often have a thinner consistency and a strong chemical smell.

How long does it take to change L248 Premix in real conditions?

The official regulations are 5 years or 160,000 km. However, in the Russian climate (frequent temperature changes), it is recommended to reduce the interval to 4 years or 120,000 km. Signs that replacement is needed:

  • 🔋 Color change to greenish or brown.
  • 🔋 The appearance of cloudiness or flakes in the expansion tank.
  • 🔋 Frequent operation of the cooling fan at idle.

In diesel engines (for example, Nissan Terrano with K9K) antifreeze degrades faster due to the increased soot content in the system.

Can L248 Premix be used in cars of other brands?

Theoretically yes, but with reservations:

  • ✅ Suitable for Renault And Dacia (based on the platform Nissan B0).
  • ✅ Compatible with Mitsubishi And Suzuki, if their models were assembled at alliance factories.
  • ❌ Not recommended for Toyota, Honda or Kia — their cooling systems are designed for other additives.

Before use, check the material of the radiator: if it is copper or brass, L248 may cause accelerated corrosion.

What to do if you accidentally filled in the wrong antifreeze?

Algorithm of actions:

  1. Immediately drain the mixture from the system.
  2. Flush the system special cleaner (For example, Liqui Moly Kuhler-Reiniger) for 30 minutes at idle.
  3. Rinse 2-3 more times with distilled water.
  4. Fill in original L248 Premix and check the operation of the thermostat (should open at 88–92°C).

If you ignore flushing, after 3–6 months the destruction of aluminum parts will begin (the first signs are a white coating on the tank cap).
