Antifreeze for Nissan Qashqai J10: a complete guide to selection and replacement

Choice antifreeze for Nissan Qashqai J10 - a task that requires attention to detail. The first generation of the crossover (2007–2013) was equipped with gasoline (MR20DE, HR16DE) and diesel (K9K, M9R) engines, each of which has its own requirements for coolant. An error in choice can lead to corrosion of the radiator, overheating of the motor, or even failure of the pump. In this article we will look at what antifreeze is filled in from the factory, what analogues are suitable, how often to change it and what to pay attention to when replacing it.

Feature Qashqai J10 — sensitivity of the cooling system to fluid quality. For example, diesel versions with engine M9R require antifreeze with increased protection against cavitation, and gasoline ones with resistance to high temperatures. The manufacturer recommends using the original fluid Nissan Coolant L248 Premix, but there are worthy analogues on the market that meet the specifications JIS K 2234 or G12+. Below is a detailed analysis of each aspect.

Original antifreeze for Qashqai J10: what is filled from the factory

From the assembly line Nissan Qashqai J10 refilled with coolant Nissan Coolant L248 Premix (article KE902-99932). This carboxylate antifreeze based on ethylene glycol, colored blue color (important: the color is not a standard, but only a marker of the manufacturer!). Liquid meets Japanese standard JIS K 2234 and has the following characteristics:

• 🔹 Type: carboxylate (OAT), without silicates and phosphates
• 🔹 Service life: 5 years or 100,000 km (depending on operating conditions)
• 🔹 Freezing point: up to –37°C (diluted)
• 🔹 Compatibility: all engines Qashqai J10, including HR16DE, MR20DE, K9K, M9R

Important: original antifreeze L248 supplied as concentrate (diluted 1:1 with distilled water) or finished liquid (already diluted). There is a mark on the canisters with concentrate Premix - this means that the liquid is ready to be filled without additional dilution. Counterfeits often reveal themselves by the absence of a holographic sticker on the canister or unclear markings.

⚠️ Attention: Don't be confused Nissan Coolant L248 (blue) with Nissan Coolant L250 (green) - the latter is intended for newer models and is not compatible with Qashqai J10 according to the composition of the additives!

Analogues of the original antifreeze: what can be filled

If the original antifreeze is not available, analogues that meet the specifications can be used JIS K 2234 or European standard G12+. The main rule: the liquid must be carboxylate (OAT) and silicate-free. Here are the tested options:

Brand	Title	Article	Color	Notes
CoolStream	Premium	CS010-005	Red	Compatible with L248, service life 5 years
Sintec	Unlimited G12++	OB-12++	Purple	Suitable for diesel M9R/K9K
Motul	Inugel Optimal	106365	Yellow	High thermal stability, recommended for turbocharged engines
Ravenol	JC Coolant	4014835755029	Green	Compliant JIS K 2234, used in Japanese cars

When choosing an analogue, pay attention to manufacturer's approvals. For example, antifreeze CoolStream Premium has official approval Nissan, which is confirmed by certificates. But cheap fluids labeled “Universal” often contain silicates, which over time form sediment in the radiator.

Antifreeze volume in the Qashqai J10 cooling system

The total volume of coolant in Nissan Qashqai J10 depends on the engine type and configuration. Below are the data for the main modifications:

• 🔧 Gasoline engines:
  • HR16DE (1.6 l) — 5.5 liters
  • MR20DE (2.0 l) — 6.5 liters
• ⚙️ Diesel engines:
  • K9K (1.5 dCi) — 6.0 liters
  • M9R (2.0 dCi) — 7.0 liters

Important: when partial replacement (for example, when topping up) about 3–4 liters, since some of the liquid remains in the cylinder block and radiator. A complete replacement requires flushing the system and filling the full volume. For precise control, use expansion tank - the level must be between the marks MIN And MAX.

When and how often to change antifreeze in Qashqai J10

The manufacturer recommends replacing antifreeze in Nissan Qashqai J10 every 5 years or 100,000 km (whichever comes first). However, in Russian conditions the time frame may be reduced:

• 🌡️ Extreme Temperatures: if the car is operated at –30°C and below or in heat above +35°C, it should be replaced every 3–4 years.
• 🚗 Aggressive riding style: Frequent engine loads (for example, towing a trailer) accelerate the degradation of additives.
• 🔧 Leaks or repairs: If antifreeze was added with water or mixed with other liquids, a complete replacement must be done immediately.

Signs that antifreeze has lost its properties:

• 🔴 Darkening or cloudiness of the liquid (indicates corrosion).
• 🟠 The appearance of sediment or flakes in the expansion tank.
• 🟣 A sharp sweetish smell (may indicate a leak into the interior through the stove).

Step-by-step instructions for replacing antifreeze

Replacing antifreeze in Qashqai J10 does not require special equipment, but will require care. You will need:

• 🔧 10 mm wrench (for drain plug).
• 🛢️ Container for old antifreeze (at least 7 liters).
• 💧 Distilled water (for rinsing).
• 🧤 Gloves and rags.

Algorithm of actions:

1. Draining old antifreeze:
   • Place the car on a level surface and let the engine cool.
   • Remove the expansion tank cap and unscrew the drain plug on the radiator (lower right corner).
   • Drain the liquid into a container. On diesel versions, additionally unscrew the plug on the cylinder block (14 mm wrench).
2. Flushing the system:
   • Close the drain plugs and fill with distilled water to the level MAX.
   • Start the engine, let it run for 5-10 minutes, then drain the water.
   • Repeat the procedure 2-3 times until the water becomes clear.
3. Filling with new antifreeze:
   • Tighten the plugs and fill in antifreeze through the expansion tank.
   • Start the engine, turn the heater on to maximum and add fluid to the level (air will leave the system).

⚠️ Attention: On diesel Qashqai J10 with engine M9R After replacing the antifreeze, an error may light up P0128 (thermostat malfunction). This is due to air entering the system. To fix the problem, sharply press the radiator hose several times with the engine running - this will help expel the air lock.

Typical mistakes when replacing antifreeze

Even experienced car owners sometimes make mistakes that lead to serious consequences. Here are the most common:

• 🚫 Mixing different types of antifreeze. For example, fill G11 (silicate) into the system where it was G12+ (carboxylate), leads to the formation of a gel and blockage of the channels.
• 🚫 Using tap water. Chlorine and salts in water accelerate the corrosion of aluminum parts (radiator, pump).
• 🚫 Incomplete drainage of old antifreeze. Remaining fluid with expired additives reduces the effectiveness of the new antifreeze.
• 🚫 Ignoring flushing. If there was sediment in the system, the new antifreeze will quickly lose its properties.

It is especially dangerous to mix antifreezes of different flowers. For example, blue Nissan L248 incompatible with red CoolStream A-110, despite similar characteristics. As a result of the reaction of the additives, a sediment may form that will clog the stove radiator - replacing it will cost 15-20 thousand rubles.

What happens if you fill in the wrong antifreeze?

Incompatible additives will react to form gel-like clumps. This will lead to:

- Engine overheating (risk of cylinder head deformation).

- Blockage of the heater radiator (failure of interior heating).

- Accelerated pump wear (due to increased cavitation).

In critical cases, it will be necessary to replace the radiator, thermostat and clean the entire system (cost from 30 thousand rubles).

Frequently asked questions about antifreeze for Qashqai J10

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

Topping up distilled water is allowed in small quantities (up to 200–300 ml) if the level has dropped due to evaporation. However, in winter this will lead to higher freezing temperatures. It is optimal to add a ready-made mixture of antifreeze and water in a 1:1 ratio.

How to check the quality of antifreeze?

Use coolant test strips (available at auto parts stores). They show the pH level and additive content. If the pH is below 7.5 or above 10.5, the antifreeze must be replaced. Also pay attention to the color: cloudiness or change in shade indicate loss of properties.

What is the difference between antifreeze for gasoline and diesel Qashqai J10?

The main difference is in additive package. Diesel engines (K9K, M9R) are more susceptible to cavitation (the formation of air bubbles), so antifreeze for them contains special inhibitors. Gasoline engines are less demanding, but need protection from high temperatures.

Do I need to flush the system when replacing antifreeze?

Yes, flushing is required if:

• They started adding water more than 2-3 times.
• The antifreeze has become cloudy or sediment is visible in it.
• Mixing of different types of liquid has occurred.

For rinsing use distilled water or special cleaning compounds (for example, LIQUI MOLY Kuhlerreiniger).

What antifreeze should I fill in after repairing the engine?

After major repairs or replacement of the pump/radiator, it is recommended to use original Nissan L248 or its equivalent with approval JIS K 2234. This is due to the fact that there may be particles of metal or old sealant left in the system, and high-quality antifreeze will help neutralize them.
