Original Nissan antifreeze: part numbers, composition and replacement rules

The engine cooling system is a critical component of any vehicle, and original Nissan antifreeze plays a key role in it. Not only the stable operation of the engine, but also the life of the pump, radiator and pipes depend on its quality. However, the market is full of fakes and analogues that can harm the cooling system. How to distinguish a real product from a counterfeit? Which part numbers are suitable for your model? Nissan? And why can’t you mix different types of antifreeze? In this article we will analyze everything in detail - from the chemical composition to step-by-step instructions for replacement.

The manufacturer strictly regulates the use original technical fluids, and antifreeze is no exception. In line Nissan Several types of coolants are presented, differing in color, composition and compatibility with system materials. For example, for modern engines VR30DDTT (installed on Skyline And Infiniti Q50) a special low-freezing composition with an increased resource is required, and for older models like Almera N16 Classic green antifreeze is suitable. Let's figure out how not to make a mistake with your choice and avoid expensive repairs.

Why is original antifreeze important for Nissan?

Many car owners believe that antifreeze is simply an “anti-freeze” and can be filled with any kind of antifreeze, as long as it does not freeze in winter. This is a dangerous misconception. Genuine Nissan coolant is developed taking into account:

• 🔬 Cooling system materials — compatibility with aluminum blocks, copper radiators and rubber pipes of a specific model.
• ⚙️ Engine thermal conditions - modern turbo engines (for example, MR20DD in Qashqai) operate at higher temperatures than naturally aspirated engines of the 2000s.
• 🛡️ Corrosion protection — original additives prevent the formation of oxides on the walls of the channels, which is especially important for engines with thin oil channels (for example, HR16DE).
• ⏳ Service life — fakes lose their properties after 1–2 years, while the original is designed for 5 years or 100,000 km.

Using non-original antifreeze is fraught with:

• 🔥 Engine overheating due to the formation of deposits in the radiator.
• 💧 Leaks through corroded pipes or pump gasket.
• 🚗 Failure of the interior heating system (the stove blows cold air).

⚠️ Attention: In engines Nissan with an aluminum block (for example, QR25DE in X-Trail T31) the use of antifreeze with silicate additives leads to accelerated corrosion. Original liquid Nissan L255N contains only organic inhibitors (OAT technology).

Articles and types of original Nissan antifreeze

Company Nissan supplies the market with several types of antifreeze, differing in composition and scope of application. Main articles and their purpose:

Article	Name / Color	Type	Application	Volume, l
KE902-99932	Nissan Long Life Coolant (green)	Hybrid (HOAT)	Old models before 2010 (Almera N16, Primera P12)	1, 5
KE902-99944	Nissan Super Long Life Coolant (blue)	Organic (OAT)	Modern models since 2010 (Qashqai J11, X-Trail T32)	1, 4
KE902-99945	Nissan Electric Vehicle Coolant (pink)	Special (for EV)	Electric cars Leaf, hybrids Note e-Power	1
KE902-99931	Nissan Concentrate Coolant (green)	Concentrate (diluted with water)	All models (requires preparation)	1

Important: Antifreeze color is not a universal indicator of compatibility. For example, green KE902-99932 and green concentrate KE902-99931 have different composition! Always focus on article numberspecified in your model's instruction manual.

For vehicles with engines Renault-Nissan Alliance (For example, K4M in Almera G15) antifreeze can be used Renault Glaceol RX Type D (article 7711428132), which is fully compatible with the original Nissan Super Long Life Coolant.

How to distinguish an original from a fake

Fake antifreeze may look identical to the original, but its composition is diluted ethylene glycol with a minimal amount of additives. Here 5 signs of counterfeit:

• 📦 Packaging - original canisters Nissan They have an embossed logo on the lid, which cannot be faked properly. Counterfeits often have blurred font or crooked seams on the plastic.
• 🔖 Label — the original contains the article number, production date and country of origin (Japan or Belgium). Fakes often lack information about the composition.
• 💧 Consistency - the original antifreeze is slightly oily to the touch, the fake is watery. When shaken, the original foams moderately, the fake foams strongly or does not foam at all.
• 🌡️ Freezing — the original can withstand −40°C without crystallization. You can check it in the freezer: the fake will thicken at −20°C.
• 🔍 Price - if antifreeze Nissan sold for less than 800–1000 rubles per liter, it is 100% fake. The original cannot be worth as an anti-freeze agent for glass.

⚠️ Attention: Counterfeit antifreeze containing high levels of methanol (rather than ethylene glycol) may cause destruction of aluminum engine parts in 6–12 months. Methanol is aggressive to metals and rubber, and its vapors are toxic.

A proven way to purchase is to order through official dealers Nissan or trusted online stores (for example, Exist.ru, Autodoc). Always ask for a certificate of conformity and a receipt indicating the article number.

How to check antifreeze for authenticity at home?

Mix a small amount of liquid with water in a 1:1 ratio and place in the freezer for 12 hours. The original will not freeze or become cloudy. Counterfeit may form flakes or ice. You can also use a hydrometer: the density of the original antifreeze at +20°C should be 1.075–1.085 g/cm³.

When and how often to change antifreeze in Nissan

The timing of antifreeze replacement depends on its type and operating conditions. Manufacturer Nissan makes the following recommendations:

• 🟢 Green antifreeze (KE902-99932) - replacement every 3 years or 60,000 km.
• 🔵 Blue Super Long Life (KE902-99944) - replacement every 5 years or 100,000 km.
• 🟣 Pink for electric vehicles (KE902-99945) - replacement every 8 years or 160,000 km (but at least level checks every 2 years).

However there is factors that shorten the service life of antifreeze:

• ⚡ Frequent engine overheating (for example, due to a faulty thermostat).
• 🚗 Operation in conditions of extreme temperatures (hot climates or severe frosts).
• 💦 Diluting antifreeze with water (even distilled) by more than 20%.
• 🔧 Repair of the cooling system with replacement of pipes or radiator.

You can check the condition of the antifreeze visually:

• 🔴 Rusty or brown color - a sign of corrosion in the system.
• ⚪ Cloudy or whitish tint - evidence of additive precipitation or mixing of incompatible types.
• 🌊 Foam or flakes - a signal about decomposition of antifreeze or oil ingress.

Step-by-step instructions for replacing antifreeze with your own hands

Replacing antifreeze in Nissan - a procedure that can be performed independently with a minimum set of tools. You will need:

• 🔧 Set of keys (for drain plug).
• 🛢️ Container for draining (at least 8 liters).
• 💧 Distilled water (10–15 liters for rinsing).
• 🧤 Gloves and rags.
• ⚖️ Hydrometer (to check density).

Sequence of actions:

1. Preparation:

   • Place the car on a flat surface (preferably on an overpass or pit).
   • Allow the engine to cool (antifreeze temperature should not exceed 40°C).
   • Remove the expansion tank cap (be careful - there may be pressure!).

2. Draining old antifreeze:

   • Place a container under the drain plug on the radiator (usually located in the lower right corner).
   • Unscrew the plug with a 10 or 12 key (depending on the model). On some vehicles (for example, Juke) the drain plug may be missing - then disconnect the lower radiator pipe.
   • Open the heater valve to maximum to allow the antifreeze to drain from the heater.

3. Flushing the system (if required):

   • Close the drain plug and fill with distilled water to the maximum level.
   • Start the engine and let it idle for 10-15 minutes.
   • Drain the water and repeat the procedure until the liquid is clear.

4. Filling with new antifreeze:

   • If you are using concentrate (KE902-99931), mix it with distilled water in a 1:1 ratio (for −40°C).
   • Slowly pour antifreeze through the expansion tank, avoiding the formation of air pockets.
   • Start the engine and warm it up to operating temperature (the fan will turn on).
   • Add antifreeze to a level between MIN And MAX.

⚠️ Attention: On vehicles with automatic transmissions (eg CVT in X-Trail) antifreeze also circulates through the automatic transmission heat exchanger. When replacing fluid, be sure to flush the system two volumes distilled water to remove any remaining antifreeze from the heat exchanger.

Compatibility with other brands and can they be mixed?

Definite answer: You cannot mix different types of antifreeze. Even if they are the same color. For example, green Nissan KE902-99932 (hybrid) incompatible with green Volkswagen G11 (silicate). Consequences of mixing:

• 🧪 Sediment falling out, clogging the radiator and engine channels.
• 🔥 Deterioration of heat transfer and risk of overheating.
• 🛑 Destruction of rubber seals and pipes.

Topping up is allowed only the same type of antifreeze, which is already loaded into the system. If you don't know what was uploaded earlier, it's better completely replace liquid. As a last resort, you can add distilled water (no more than 200–300 ml), but after that be sure to check the density with a hydrometer.

Common mistakes when replacing antifreeze and how to avoid them

Even experienced car owners make mistakes that can lead to serious damage. Here TOP-5 errors and how to prevent them:

• 🚫 Incomplete drainage of old antifreeze — up to 1–1.5 liters of liquid remain in the system, which worsens the properties of the new antifreeze.

  Solution: Flush the system with water until it runs clear. On some models (for example, Patrol Y62) To completely drain, you need to remove the lower radiator hose.

• 🌬️ Air jams - lead to overheating of the engine and poor operation of the stove.

  Solution: After adding antifreeze, remove the throttle body heating hose (if equipped) and wait until bubble-free liquid comes out of it. You can also squeeze the upper radiator hose several times.

• 💦 Using tap water — the salts and minerals contained in it form scale.

  Solution: Use only distilled water for diluting the concentrate or washing.

• ❄️ Wrong dilution ratio - too “weak” antifreeze will freeze in winter, too “strong” - it will lose its heat-removing properties.

  Solution: Mix the concentrate with water in a 1:1 ratio at a temperature of −40°C. In the southern regions, a ratio of 2:3 (antifreeze:water) is allowed for −25°C.

• 🔧 Ignoring level check after replacement — antifreeze “leaves” into the system and its level drops.

  Solution: 1-2 days after replacement, check the level in the expansion tank and top up if necessary.

Another common mistake is replacing antifreeze without checking the system for leaks. If there is a microcrack somewhere (for example, in the radiator or pipe), the new antifreeze will quickly leak, and you will be sinning on its quality. Before replacing, inspect:

• 🔍 Pipes for cracks.
• 🔥 Condition of the radiator (especially after an accident).
• 🚗 Pump gasket (a common cause of leakage on Qashqai with engine MR20DE).

FAQ: Answers to frequently asked questions

Is it possible to put another brand of antifreeze into a Nissan if it is the same color?

No, color does not guarantee compatibility. For example, red antifreeze Toyota and red Nissan have different composition. Always focus on article number and standard (OAT, HOAT, etc.).

How often should you check the antifreeze level?

Minimum - once a month, and also before long trips. On most models Nissan The expansion tank is transparent and the level can be seen without opening the lid. The optimal level is between the marks MIN And MAX.

What happens if you don't change antifreeze on time?

Aging of additives leads to:

• Corrosion of aluminum parts (for example, cylinder block).
• The radiator becomes clogged with deposits (cooling deteriorates).
• Destruction of rubber seals and leaks.
• Engine overheating, especially in traffic jams.

In practice this may turn out to be block head repair (from 50,000 rubles) or replacing the radiator (from 20,000 rubles).

Can EV antifreeze (pink) be used in a regular Nissan?

No, pink antifreeze KE902-99945 designed specifically for electric vehicle cooling systems Leaf and hybrids. It has a different additive package and is not compatible with traditional internal combustion engines.

How to recycle old antifreeze?

Antifreeze is a toxic liquid and should not be poured down the drain or onto the ground. Hand over used antifreeze to hazardous waste collection points or service stations that have a disposal license. Some auto chemical stores accept old technical fluids when purchasing new ones.
