Coolant L248 - original antifreeze from Nissan, developed specifically for the engines of the Japanese automaker. This composition belongs to the class hybrid antifreezes (G11/G12+), which provides it with unique properties: high temperature stability, corrosion protection and extended service life. However, there are many myths surrounding L248 - from claims about its “forever” formula to disputes about compatibility with other brands.

In this article we will look at the exact chemical composition of L248, official Nissan recommendations for replacement, and we will also reveal a list of proven analogues that will not harm the cooling system of your car. We will pay special attention to the nuances of mixing, the consequences of using fakes and step-by-step instructions for self-replacement - taking into account the specifics of different models Nissan (from Qashqai to Patrol).

What is L248 antifreeze: technical specifications

Antifreeze Nissan L248 (article KE902-99932) is hybrid coolant based on ethylene glycol, meeting standards JIS K 2234 And Nissan MSE M3301. Its key features:

  • 🔹 Color: officially - green (but the shade can vary from turquoise to light green depending on the batch).
  • 🔹 Type: hybrid (contains both organic and inorganic corrosion inhibitors).
  • 🔹 Service life: to 6 years or 120,000 km (provided there is no dilution with water).
  • 🔹 Temperature range: from -37°C to +129°C (depends on concentration).

Unlike traditional antifreezes (e.g. G11), L248 contains phosphates and silicates, which form a protective film on metal surfaces. This prevents corrosion of aluminum parts (relevant for engines Nissan HR16DE, MR20DD, VQ35DE etc.). However, it is precisely because of phosphates that it cannot be mixed with most European carboxylate-based antifreezes (G12++/G13).

⚠️ Attention: If your cooling system previously used a different type of antifreeze (such as CoolStream Premium or Castrol Radicool SF), a complete replacement of L248 will require flushing the system special compounds (for example, LIQUI MOLY Kuhler-Reiniger). Ignoring this rule will lead to the formation of gel-like deposits that will clog the radiator and pump.

Which Nissan models does the L248 fit?

Officially antifreeze L248 recommended for all cars Nissanreleased after 2005, including:

Model Years of manufacture Engines Features
Qashqai (J10, J11) 2007–present HR16DE, MR20DD, M9R Requires dilution with distilled water 1:1 for the Russian climate
X-Trail (T31, T32) 2007–2021 MR20DE, QR25DE, M9R In models with CVT replacing antifreeze is critical to preserving the life of the variator
Patrol (Y62) 2010–present VK56VD, VK50VD Used in concentrated form (without dilution) for hot climates
Navara (D40, NP300) 2005–present YD25DDTi, VQ40DE Mixing with cheap antifreezes leads to the destruction of pump seals

For older models (eg Primera P12 or Almera N16) L248 does not fit - they use antifreeze of the old standard Nissan L250 (blue color). Also L248 is not compatible with hybrid systems Nissan e-Power (for example, in Note or Kicks), where a specialized fluid is required Nissan L255.

Original vs analogues: what can be filled instead of L248?

Cost of original antifreeze Nissan L248 (about 1,200–1,500 RUR per liter) pushes many owners to look for analogues. However, not all substitutes are equally safe. Below is the list certified analogues, which comply with the standard Nissan MSE M3301:

  • 🔧 Ravenol HJC Hybrid Japanese Coolant (article 4014835755107) - complete analogue in composition, suitable for all engines Nissan.
  • 🔧 CoolStream JPN - Russian brand, but has been tested for compatibility with aluminum blocks VQ And MR.
  • 🔧 AWM HJC Premium - used by dealers Nissan in Europe as an alternative to L248.
  • 🔧 Sintec Unlimited JPN - budget option (approx. 500 ₽/l), but requires replacement every 3 years.

What cannot be filled in instead of L248:

  • ❌ Antifreeze based carboxylates (G12++, G13) - for example, Castrol Radicool SF or Motul Inugel Optimal. They do not contain the phosphates needed to protect the aluminum.
  • ❌ Cheap domestic antifreeze (for example, Felix Carbox or Lukoil G12) - can cause corrosion of copper and brass in the radiator.
  • ❌ Universal “lobrid” antifreezes (for example, Total Glacelf Auto Supra) - incompatible with silicate additives L248.
💡

Before buying an analogue, check the availability of a certificate Nissan MSE M3301 on the packaging. Counterfeits often imitate the green color, but do not contain the necessary additives.

When and how often to change L248 antifreeze?

Official regulations Nissan prescribes replacement of antifreeze every 6 years or 120,000 km - whichever comes first. However, there are nuances:

  • 🔥 In regions with hot climate (for example, Krasnodar region, Crimea) or when operating in mountainous area service life is reduced to 4 years.
  • ❄️ If antifreeze is diluted with water (for example, during leaks), its properties are lost after 2–3 years.
  • 🚗 In cars with turbocharged engines (For example, Nissan Juke 1.6 DIG-T) replacement is required every 90,000 km.

Signs that it's time to change antifreeze:

  • 🔸 Change color to brown or rusty (indicates corrosion).
  • 🔸 Appearance sediment or flakes in the expansion tank.
  • 🔸 Frequent engine overheating at normal fluid levels.
  • 🔸 Smell burning or acid from under the hood.
⚠️ Attention: If the antifreeze appears air bubbles with the engine running, this may indicate broken cylinder head gasket (especially relevant for Nissan Almera G15 with engine HR16DE). In this case, urgent diagnosis is required!

Step-by-step instructions for replacing antifreeze L248

Replacing antifreeze in Nissan has its own characteristics related to the design of the cooling system. You will need:

  • 🛠️ New antifreeze L248 (volume depends on the model, see table below).
  • 🛠️ Distilled water (if rinsing is required).
  • 🛠️ Set of sockets and wrench on 10 mm for the drain plug.
  • 🛠️ Funnel and container for old antifreeze (at least 8 liters).

Make sure the engine is cool (temperature below 50°C)|

Open the expansion tank cap to relieve pressure|

Prepare a container for drainage under the radiator|

Check for a new gasket for the drain plug (Nissan part number 21050-4M000)-->

Step 1. Drain the old antifreeze

  1. Place the car on flat surface (better - on an overpass or lift).
  2. Remove engine protection (if there is one). B Nissan Qashqai J11 To do this you need to unscrew 4 bolts.
  3. Place the container under radiator drain plug (located in the lower right corner). In some models (for example, X-Trail T32) the plug is plastic - unscrew it carefully!
  4. Unscrew the plug and wait until the liquid is completely drained (approx. 10–15 minutes).

Step 2: Flush the system (if necessary)

If the drained fluid contains sediment or is heavily contaminated, flushing is required. To do this:

  1. Close the drain plug.
  2. Pour into the system distilled water (or a special cleaner, for example, Wynns Cooling System Flush).
  3. Start the engine and let it run 10–15 minutes at idle speed.
  4. Drain the water and repeat the procedure if it remains dirty.

Step 3. Filling with new antifreeze

For different models Nissan Different volumes of liquid are required:

Model Cooling system volume Recommended concentration
Qashqai J11 (1.6/2.0) 6.5–7.0 l 50% antifreeze + 50% water
X-Trail T32 (2.5) 8.0–8.5 l 60% antifreeze + 40% water (for cold climates)
Patrol Y62 (5.6) 12.0–12.5 l 100% concentrate (for hot climates)

After filling:

  1. Start the engine and let it run 5–7 minutes with the expansion tank cap open (for air to escape).
  2. Add antifreeze to the level MAX (with the engine cooled down).
  3. Check the system for leaks (there are no leaks from under the plug or pipes).
💡

After replacing the antifreeze within first 500 km Avoid sudden loads on the engine - this will help distribute additives evenly throughout the system.

Common replacement errors and their consequences

Even experienced car owners make mistakes that can lead to engine overheating or destruction of the pump. Let's look at the most common ones:

  • 🚫 Mixing L248 with other antifreezes (for example, with G12++). Consequence: education gel, which clogs the heater radiator and the main radiator. Symptoms: poor interior heating in winter, frequent activation of the cooling fan.
  • 🚫 Using tap water for dilution. Consequence: scale deposits on the walls of the cylinder block and radiator, reduced heat transfer.
  • 🚫 Incomplete drainage of old antifreeze. Remaining expired fluid accelerates corrosion. Especially dangerous for Nissan Juke with aluminum block HR16DET.
  • 🚫 Replacement without flushing after using cheap antifreeze. Consequence: destruction of the pump sealing rings (part number 21091-JK00A for Qashqai).

How to avoid mistakes?

  • ✅ Before adding new antifreeze blow out the system with compressed air (for example, through a fitting on the return pipe).
  • ✅ Use only distilled water (can be purchased at a pharmacy or auto store).
  • ✅ After replacement control the level first 1,000 km — Possible air leaks.
What to do if after replacing the antifreeze quickly darkens?

If the new antifreeze L248 darkens during the first 500 km, this indicates:

1. Remains of old fluid - Re-rinsing is required.

2. Corrosion in the system — check the condition of the radiator and cylinder block (especially important for Nissan Almera N16 with cast iron block).

3. Counterfeit antifreeze — the original L248 should not change color so quickly.

FAQ: Frequently asked questions about L248 antifreeze

Can L248 be mixed with a different color of antifreeze?

No! Color does not determine compatibility. L248 can only be mixed with antifreezes that meet the standard Nissan MSE M3301 (For example, Ravenol HJC). Mixing with G12++ or G13 will lead to precipitation.

How to distinguish the original L248 from a fake?

The original antifreeze has:

  • 🔹 Holographic sticker on a canister with an article number KE902-99932.
  • 🔹 Density 1.065–1.075 g/cm³ at +20°C (checked with a hydrometer).
  • 🔹 Strong alcohol smell (counterfeits often smell sweet).

Counterfeits are usually sold in cans without a bottling date or with misspellings (for example, "Nissan" is spelled "Nissan").

What happens if you don’t change antifreeze for more than 6 years?

After expiration of service life:

  • 🔥 Boiling point decreases - the risk of engine overheating increases by 30–40%.
  • ❄️ Frost resistance deteriorates - the liquid may freeze already at -20°C.
  • 🛑 Seals are destroyed - especially dangerous for the pump (replacement cost - from 8 000 ₽).

B Nissan X-Trail T31 with engine MR20DE prolonged replacement of antifreeze often leads to radiator leaks (article 21410-4M000).

Can L248 be used in other brands of cars?

Theoretically, yes, but with reservations:

  • ✅ Suitable for Renault (For example, Duster, Koleos), since they use the same engines (HR16DE, MR20DE).
  • ❌ Not recommended for Toyota, Honda or Kia/Hyundai - they have different standards (for example, Toyota Super Long Life Coolant).
  • ⚠️ B Mitsubishi (For example, Outlander) can only be used after the system has been completely flushed.
How to properly dilute L248 concentrate?

Proportions depend on climatic conditions:

Proportion (antifreeze:water) Freezing point Recommendations
50:50 -37°C Optimal for most regions of Russia
60:40 -45°C For Siberia and the Far East
100:0 -18°C Only for hot climates (eg UAE)

Use only distilled water — tap water contains salts that accelerate corrosion.
