Original antifreeze for Nissan X-Trail T32: part number and specifications

From factory to Nissan X-Trail T32 (including restyled versions 2017–2020) coolant is added Nissan Long Life Coolant (LLC) green color. This antifreeze meets internal specifications KE902-99931 (concentrate) or KE902-99932 (ready liquid). It is important to note that the original product is manufactured by Calsonic Kansei - official supplier for Nissan.

Characteristics of factory antifreeze:

• 🔹 Type: carboxylate (OAT - Organic Acid Technology), free of silicates and phosphates.
• 🔹 Color: green (not to be confused with traditional green silicate antifreezes, for example, G11).
• 🔹 Service life: up to 5 years or 160,000 km (depending on operating conditions).
• 🔹 Freezing point: −37°C (with proper dilution of the concentrate).

Original antifreeze Nissan LLC sold in two versions:

• 📦 Concentrate (article KE902-99931) - requires dilution with distilled water in a 50/50 ratio.
• 📦 Ready liquid (article KE902-99932) - already diluted and ready for pouring.

⚠️ Attention: Do not confuse the original green antifreeze Nissan LLC with cheap silicate analogues of green color (for example, G11). The latter are incompatible with aluminum engine parts X-Trail T32 and may cause corrosion.

Why is the right choice of antifreeze for X-Trail T32 important?

Engines Nissan X-Trail T32 (petrol MR20DD And QR25DE, diesel R9M) have aluminum blocks and heads, which are especially sensitive to the composition of the coolant. Incorrect antifreeze can lead to:

• 🔥 Engine overheating due to the formation of deposits in the radiator and channels.
• 🛑 Corrosion of aluminum partsif the liquid contains silicates or phosphates.
• ⚡ Damage to seals and hoses when using aggressive additives.
• ❄️ Freezing of liquid in winterif the antifreeze concentration is insufficient.

Manufacturer Nissan insists on use only carboxylate antifreeze (type OAT), since they provide:

• 🛡️ Long-term protection against corrosion without the formation of a protective layer (unlike silicate antifreeze).
• 🔄 Stability of properties throughout the entire service life.
• 🌡️ Optimal heat transfer, which is critical for modern turbocharged and diesel engines.

Analogues of the original antifreeze: what can be filled instead of Nissan LLC

If the original antifreeze Nissan LLC not available, can be used certified analogues, meeting specifications JIS K 2234 (Japanese standard) or ASTM D3306 (American standard). The main condition is that the liquid must be carboxylate (OAT) and do not contain silicates, amines or phosphates.

The table below shows proven analogues compatible with X-Trail T32:

Brand	Product name	Article	Color	Type	Notes
Coolstream	Coolstream OAT	CS010-005	Green	OAT	Complete analogue Nissan LLC, recommended for Japanese cars.
Ravenol	JC Coolant OAT	4014835755057	Green	OAT	Compliant JIS K 2234, suitable for Nissan And Infiniti.
Sintec	Sintec Unlimited	50406	Red	Lobrid (OAT + silicates)	Allowed, but requires flushing the system when switching from Nissan LLC.
Motul	Inugel Optimal	105775	Orange	OAT	Universal, but the color does not match the original.
Liqui Moly	Kuhlerfrostschutz KFS 2001 Plus	8940	Green	OAT	Suitable for Japanese and Korean cars, but service life is 3 years.

When choosing an analogue, pay attention to:

• 🔬 Composition: should be specified as OAT or Carboxylate-based.
• 📋 Certificates: compliance JIS K 2234 or Nissan KE902-99931.
• 🎨 Color: not critical, but the green color makes it easier to control the level.

⚠️ Attention: Do not mix different types of antifreeze (e.g. OAT And G11)! This can cause a gel or sediment to form that will clog the radiator. When switching to another type of fluid, be sure to flush the system with distilled water.

How to check the level and condition of antifreeze in X-Trail T32

Regularly checking the level and condition of antifreeze is a mandatory procedure for Nissan X-Trail T32. It is recommended to do this every 10,000 km or before a long trip. The expansion tank is located in the engine compartment on the driver's side (on most versions).

Step-by-step verification instructions:

1. ✅ Make sure the engine has cooled down (checking on a hot engine is prohibited!).
2. ✅ Open the hood and find the expansion tank (transparent plastic tank with a lid, marked COOLANT).
3. ✅ The fluid level must be between the marks MIN And MAX.
4. ✅ Check the color and consistency of the antifreeze:
   • ✔️ Norm: green (or other original color), transparent, without sediment.
   • ❌ Warning signs: cloudy color, flakes, rusty tint, pungent odor.

If the level is lower MIN, add antifreeze of the same brand that is already filled. If the fluid becomes cloudy or changes color, a complete replacement is required.

When and how to change antifreeze in Nissan X-Trail T32: step-by-step instructions

According to the regulations Nissan, replacing antifreeze in X-Trail T32 required every 5 years or 160,000 km (whichever comes first). However, under severe operating conditions (frequent overheating, extreme temperatures, city traffic jams), the interval is reduced to 3–4 years.

Signs that it’s time to change the antifreeze:

• 🔴 The color has turned brown or rusty.
• 🔴 Sediment or flakes have appeared in the expansion tank.
• 🔴 Frequent engine overheating for no apparent reason.
• 🔴 Antifreeze has lost transparency or become cloudy.

Step-by-step replacement instructions:

1. 🔧 Preparation:
   • Place the car on a level surface.
   • Allow the engine to cool (at least 2 hours after driving).
   • Prepare a container for draining (volume of at least 8 liters).
2. 🔧 Draining old antifreeze:
   • Remove the expansion tank cap.
   • Unscrew the drain plug on the radiator (lower part, driver's side).
   • Unscrew the plug on the engine block (if provided).
   • Wait until the liquid is completely drained.
3. 🔧 Flushing the system (if necessary):
   • Pour distilled water into the system.
   • Start the engine and let it run for 10-15 minutes.
   • Drain the water and repeat the procedure if the liquid remains dirty.
4. 🔧 Filling with new antifreeze:
   • Reinstall all plugs.
   • Pour in the concentrate diluted with distilled water (50/50) or the prepared liquid.
   • Start the engine and run it for 5-10 minutes to remove any air pockets.
   • Add antifreeze to the level MAX.

Antifreeze volume in the cooling system Nissan X-Trail T32 is approximately 7.5–8.5 liters (depending on engine and configuration). After replacement, check the level after 1-2 days and top up if necessary.

What to do if after replacing the antifreeze quickly darkens?

If the new antifreeze turns dark after a few days, this may indicate:

- remains of old fluid in the system (re-flushing is required);

- corrosion in the radiator or engine (diagnostics required);

- use of low-quality or incompatible antifreeze (replace with a certified analogue).

Common mistakes when replacing antifreeze and how to avoid them

Many owners Nissan X-Trail T32 make mistakes when replacing antifreeze, which can lead to serious consequences. Let's look at the most common of them:

Mistake 1: Using tap water

Distilled water is the only acceptable diluent for concentrate. Tap water contains salts and minerals that:

• 🔸 Accelerate corrosion of aluminum parts.
• 🔸 Reduces the service life of antifreeze.
• 🔸 May cause scale formation in the radiator.

Mistake 2: Mixing different types of antifreeze

Even if the colors are the same, mix OAT (For example, Nissan LLC) with silicate (G11) or hybrid (G12+) antifreeze cannot be used. This leads to:

• 🔸 Precipitation that clogs the channels.
• 🔸 Loss of anti-corrosion properties.
• 🔸 Risk of engine overheating.

Error 3: Incomplete drainage of old antifreeze

If more than 10–15% of old fluid remains in the system, it may:

• 🔸 Worse the properties of the new antifreeze.
• 🔸 Cause a chemical reaction between additives.
• 🔸 Lead to the formation of gel.

Mistake 4: Ignoring air pockets

After replacing the antifreeze, air pockets may remain in the system, which:

• 🔸 Lead to local overheating of the engine.
• 🔸 Causes incorrect temperature sensor readings.
• 🔸 May cause stove failure.

To avoid traffic jams, after adding antifreeze:

1. Start the engine and let it idle for 5-10 minutes.
2. Periodically squeeze the radiator pipes to speed up circulation.
3. Add antifreeze to the level MAX after the engine has cooled down.

FAQ: Frequently asked questions about antifreeze in Nissan X-Trail T32

Is it possible to fill X-Trail T32 with G12++ or G13 antifreeze?

Theoretically G12++ And G13 (lobrid antifreeze) compatible with OAT, but The manufacturer recommends that you adhere to the original specifications. If you decide to use G12++, select products marked JIS K 2234 and perform a complete flush of the system before replacement. G13 (propylene glycol based) is less aggressive to aluminum, but its use does not guarantee compliance with factory requirements.

What happens if you don’t change antifreeze for more than 5 years?

Over time, antifreeze loses its properties:

• 🔸 Boiling point decreases - risk of engine overheating.
• 🔸 Anti-corrosion properties deteriorate — the destruction of aluminum parts begins.
• 🔸 Deposits form — the radiator and pump channels become clogged.
• 🔸 Increased risk of cavitation — destruction of the pump blades.

In critical cases this can lead to overheating of the engine, deformation of the cylinder head or jamming of the pistons.

What kind of antifreeze is poured into the X-Trail T32 on the assembly line in Russia?

At the factory Nissan in St. Petersburg (where they collect X-Trail T32 for the Russian market) the same Nissan Long Life Coolant (KE902-99931/32), as in Japanese enterprises. Color - green, type - OAT. Some batches may contain antifreeze from Coolstream (supplier for Nissan), but with identical characteristics.

Is it possible to add water to antifreeze in the summer?

Top up distilled water in small quantities (up to 200–300 ml) is allowed if the antifreeze level has dropped due to evaporation. However:

• 🔸 Do not exceed the ratio of 50/50 (antifreeze/water), otherwise the freezing temperature will decrease.
• 🔸 After adding water, check the density with a hydrometer (should be at least 1.075 g/cm³).
• 🔸 Restore the antifreeze concentration as soon as possible.

Using regular water prohibited!

Where to buy original Nissan LLC antifreeze?
