What antifreeze to fill in Nissan Almera G15 (2013-2022): original, analogues, volume and replacement

Choosing the right antifreeze for Nissan Almera G15 (2013-2022) is a task that requires attention to detail. An error in the selection of coolant can lead to corrosion of aluminum engine parts, overheating, or even failure of the pump. In this article we will look at what antifreeze is filled in from the factory, which analogues are suitable for refilling and complete replacement, as well as the nuances of the replacement procedure.

Models Almera G15 with gasoline engines HR16DE (1.6 l) and K4M (1.6 l, for CIS markets) have specific requirements for coolant. The manufacturer recommends using green antifreeze based on ethylene glycol with additive package Nissan Long Life Coolant (code KE902-99931), but there are worthy analogues on the market. It is important to consider not only the color, but also the standard of the liquid - for Almera G15 this is JIS K 2234 or Nissan Coolant L250.

Original antifreeze for Nissan Almera G15: part numbers and specifications

From factory to Nissan Almera G15 original coolant is added Nissan Long Life Coolant (L250). It is green in color and meets Japanese standard JIS K 2234. Key Features:

• 🔹 Color: green (not to be confused with G11 or G12+)
• 🔹 Base: ethylene glycol + organic additives
• 🔹 Service life: 5 years or 100,000 km (depending on operating conditions)
• 🔹 Freezing point: down to -37°C (with proper dilution)

The original antifreeze comes in two versions:

Article	Volume	Type	Note
KE902-99931	1 l (concentrate)	Nissan Long Life Coolant	Requires dilution with distilled water 1:1
KE902-99932	5 l (ready solution)	Nissan Long Life Coolant	Already diluted, can be poured without preparation
KE902-99944	4 l (concentrate)	Nissan Super Long Life Coolant	For new models, but compatible with G15

Important: original antifreeze Nissan not compatible with silicate-based fluids (e.g. G11) or hybrid antifreezes (G12+). Mixing may cause gel-like deposits to form in the radiator.

⚠️ Attention: If you buy antifreeze in retail stores, check the label for compliance with the standard JIS K 2234. Even if the liquid is green, this does not guarantee compatibility with Almera G15.

Analogues of the original antifreeze: what can be filled instead of Nissan L250

The original fluid is not always available, so many owners Almera G15 looking for analogues. The main rule: the analogue must comply with the standard JIS K 2234 or have clearance Nissan Coolant L250. Here are the tested options:

• 🔧 CoolStream JPN: complete analogue of the original, green, article number CS-JPN-1 (1 l) or CS-JPN-5 (5 l). Produced in Russia according to Japanese standards.
• 🔧 Ravenol JLC: German antifreeze with approval for Japanese cars, article number 4014835734607 (1.5 l).
• 🔧 Totachi Long Life Coolant: Japanese brand, item number T22001 (4 l). Used on conveyors Nissan And Toyota.
• 🔧 Sintec Unlimited: Russian antifreeze with approval JIS K 2234, article SINTEC-UNLIMITED-G12++ (despite the G12++ marking, it is compatible with Almera G15).

When choosing an analogue, avoid antifreeze labeled G11 (silicate) or G13 (propylene glycol). They are not suitable for aluminum engines HR16DE And K4M. It is also not recommended to use universal fluids such as Felix or Lukoil without checking for compliance with the standard JIS K 2234.

If you are in doubt about your choice, pay attention to color and smell liquids. Original antifreeze for Almera G15 It has a bright green tint and a faint sweetish odor. Counterfeits are often dull or have a strong chemical odor.

The volume of antifreeze in the cooling system of Nissan Almera G15

The total volume of coolant in Nissan Almera G15 depends on engine type and configuration:

• 🔢 HR16DE (1.6 l, 110 hp): 6.7 liters (including heater radiator).
• 🔢 K4M (1.6 l, 102 hp, for CIS): 6.5 liters.

When completely replacing antifreeze, you will need 5.5–6 liters finished fluid (taking into account the residues in the cylinder block). If you use a concentrate, it must be diluted with distilled water in the proportion 1:1 to reach a freezing temperature of -37°C.

⚠️ Attention: When refilling antifreeze, do not exceed the maximum level in the expansion tank (mark MAX). Overfilling can cause liquid to be squeezed out of the plug when heated.

If you are planning a partial replacement (for example, due to a leak), 1-2 liters of antifreeze is enough. However, in this case it is recommended to use the same brand that was poured earlier. Mixing different types of liquids (even if they are green) can cause a chemical reaction and the formation of sediment.

What happens if you overfill antifreeze?

If the level in the expansion tank is exceeded, excess pressure during heating can force the liquid through the plug valve. This will lead to loss of antifreeze and the risk of engine overheating. In addition, excess fluid may enter the crankcase ventilation system, which will negatively affect the operation of the internal combustion engine.

When to change antifreeze in Nissan Almera G15: regulations and signs of wear

The manufacturer recommends replacing antifreeze in Nissan Almera G15 every 5 years or 100,000 km (whichever comes first). However, in Russian conditions (with sharp temperature changes and aggressive operation), it is better to reduce the interval to 3–4 years or 60,000 km.

Signs that antifreeze has lost its properties and requires replacement:

• 🔴 Color Change: the liquid has turned brown or cloudy.
• 🔴 Sediment or flakes: Rust particles or gel-like clots are visible in the expansion tank.
• 🔴 Foam on surface: indicates a violation of the chemical composition.
• 🔴 Burning smell: may indicate overheating or decomposition of additives.
• 🔴 Frequent engine overheating: even with a working thermostat and fan.

If you notice any of these signs, check the condition of the antifreeze using test strips (sold in auto stores). They show the pH level and the content of corrosion inhibitors. Normal pH for Almera G15 — 7,5–9,5.

Step-by-step instructions for replacing antifreeze in Nissan Almera G15

Replacing antifreeze in Almera G15 does not require special equipment, but will require care. You will need:

• 🛠️ New antifreeze (6-7 liters).
• 🛠️ Distilled water (10 l).
• 🛠️ A set of keys and sockets (especially for 10 And 14).
• 🛠️ Container for draining (at least 7 l).
• 🛠️ Funnel and hose for pouring.
• 🛠️ Gloves and rags.

Replacement process:

1. Draining old antifreeze:
   • Place the car on a level surface and let the engine cool.
   • Remove the expansion tank cap (slowly to relieve pressure).
   • Place a container under the drain hole on the radiator (bottom right) and unscrew the plug with a key 14.
   • Unscrew the plug on the cylinder block (key on 10, located next to the oil filter).
   • Allow the liquid to drain completely (10–15 minutes).
2. Flushing the system (optional):
   • Tighten the drain plugs and pour distilled water through the expansion tank.
   • Start the engine and let it idle for 5-10 minutes.
   • Drain the water and repeat the procedure 2-3 times until the water runs clear.
3. Filling with new antifreeze:
   • If you use concentrate, mix it with distilled water in the proportion 1:1.
   • Fill the liquid through the expansion tank to the mark MAX.
   • Start the engine, turn the heater on to maximum and let it run for 5-7 minutes.
   • Add antifreeze to the level (if necessary) and screw on the cap.

⚠️ Attention: After replacing antifreeze, check the level in the expansion tank for the first 2-3 days. Air pockets may leave the system, which will lead to a decrease in the level.

If after replacement the heater blows cold air, it means there is air left in the system. To remove it:

1. Start the engine and let it run for 2-3 minutes.
2. Revise the throttle several times (up to 3000 rpm).
3. Unscrew the expansion tank cap and squeeze the upper radiator hose with your hand to squeeze out the air.
4. Add antifreeze to the level and repeat the procedure.

Common mistakes when replacing antifreeze and how to avoid them

Even experienced car owners make mistakes when replacing coolant. Here are the most common ones and how to prevent them:

• ❌ Mixing different types of antifreeze: For example, green JIS K 2234 with red G12+. This leads to a chemical reaction and the formation of a precipitate.
  Solution: Use only compatible fluids or flush the system before replacing.
• ❌ Ignoring flushing: If old antifreeze with deposits remains in the system, the new one will quickly lose its properties.
  Solution: Flush the system with distilled water until the drain is clear.
• ❌ Incorrect dilution of concentrate: A solution that is too weak will freeze in winter, and a solution that is too strong will lose its heat capacity.
  Solution: Mix concentrate with water in proportion 1:1 for the climate of Russia.
• ❌ Forgetting to remove air plugs: This leads to poor operation of the stove and overheating of the engine.
  Solution: After replacement, re-gas several times and check the level.
• ❌ Using tap water: Salts and impurities in water accelerate corrosion.
  Solution: Use only distilled water.

Critical error: adding antifreeze without pre-cooling the engine. The hot fluid in the system is under pressure, and unscrewing the plug can cause serious burns.

Answers to frequently asked questions about antifreeze in Nissan Almera G15

Is it possible to mix original Nissan antifreeze with CoolStream JPN?

Yes, CoolStream JPN is a complete analogue of the original liquid and has the same standard JIS K 2234. Mixing will not lead to negative consequences, but it is recommended to use one brand for a complete replacement.

What antifreeze is installed in the 2020 Almera G15 from the factory?

On the assembly line in the 2020 model it is filled Nissan Long Life Coolant (L250) green with article number KE902-99932 (ready solution). Sometimes used for CIS markets Totachi Long Life Coolant.

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

Aging of antifreeze leads to:

• Corrosion of aluminum engine parts (cylinder head, radiator).
• Deterioration of heat transfer and engine overheating.
• Destruction of rubber pipes and pump seal.
• Scale formation in the channels of the cooling system.

In critical cases this can lead to engine jam or radiator rupture.

How to check the antifreeze level in Almera G15?

The level is checked visually in the expansion tank. Normal level is between the marks MIN And MAX. Carry out the test on a cold engine, as the liquid expands when heated.

If the level is lower MIN, add antifreeze of the same brand. If the tank is empty, check the system for leaks (especially at the junction of the pipes and the radiator).

Is it possible to use G12++ antifreeze instead of the original one?

Theoretically G12++ (For example, Sintec Unlimited) compatible with Almera G15, as it does not contain silicates. However, the manufacturer recommends adhering to the standard JIS K 2234. If you decide to fill G12++, make sure it does not contain borates or amines.
