Selecting and replacing antifreeze in Nissan Almera G15 - a task that requires attention to detail. Not only the stable operation of the engine, but also the service life of the radiator, pump and pipes depends on the correct type of coolant. Many owners are faced with questions: what kind of antifreeze is poured in from the factory, is it possible to mix different types, and how often does it need to be changed?
In this article we will analyze all the nuances - from official recommendations Nissan to practical advice on replacement. You will find out which liquids are compatible with HR16DE And K4M engines, how to check the antifreeze level, and what to do if the cooling system requires flushing. And also typical mistakes that reduce engine life.
Official Nissan antifreeze recommendations for Almera G15
The manufacturer clearly regulates which antifreeze should be used in Almera G15 (2012–2019). According to the service documentation, for all modifications - the same as with gasoline HR16DE (1.6 l), and with K4M (1.6 l, Renault-Nissan) - provided ethylene glycol based coolant with a long service life (Long Life Coolant, LLC).
Original antifreeze from Nissan has a catalog number KE902-99932 (concentrate) or KE902-99931 (ready liquid). This green antifreeze type G-11 (according to VW classification), but with unique additives adapted for aluminum engine blocks Renault-Nissan. Important: Despite the color, it cannot be mixed with traditional G-11 from other brands!
⚠️ Attention: Antifreeze KE902-99932 supplied as a concentrate. To dilute, use only distilled water in a 50/50 ratio (for climates with temperatures down to -37°C). In regions with frosts below -40°C, a ratio of 60% concentrate to 40% water is allowed.
Service life of original antifreeze - 5 years or 100,000 km (whichever comes first). However, in the conditions of the Russian climate and fuel quality, many services recommend reducing the interval to 3–4 years.

Compatible analogues: what can be filled instead of the original
Original antifreeze Nissan is not always available, and its price is higher than its analogues. Fortunately, there are several proven alternatives that are fully compatible with Almera G15:
- 🔹 CoolStream A-110 — Russian analogue, certified for Renault-Nissan. It has a green color and an identical additive package.
- 🔹 Motul Inugel Optimal - universal antifreeze that meets the standard Nissan LLC. Suitable for all engines Almera G15.
- 🔹 Ravenol HJC Hybrid Japanese Coolant — premium option with an extended service life (up to 250,000 km).
- 🔹 Liqui Moly KFS 2001 Plus — compatible with aluminum radiators and cylinder blocks.
Selection criterion: Look for compliance on the label Nissan LLC or Renault Type D. The color of the liquid is not the determining factor - it is the additive formula that is important. For example, red antifreeze G12++ from VW not suitable for Almera G15, despite the high characteristics.
Why can't you mix different types of antifreeze?
Mixing fluids with different additive packages (for example, G11 and G12) leads to a chemical reaction, which results in the formation of flakes and sediment. This clogs the radiator passages, impairs heat transfer and can cause the engine to overheat. In extreme cases, corrosion of aluminum parts.

Antifreeze volume in the Almera G15 cooling system
The total volume of coolant in Nissan Almera G15 depends on engine type and configuration:
- 🔧 HR16DE (1.6 l, 117 hp) — 6.7 liters (including expansion tank).
- 🔧 K4M (1.6 l, 102 hp, Renault) — 6.5 liters.
When complete replacement (with flushing) required 7–8 liters finished liquid or 4–4.5 liters of concentrate (for dilution). If you only add antifreeze, it is enough 1–1.5 liters.
⚠️ Attention: When replacing antifreeze in Almera G15 with automatic transmission (variator Jatco) be sure to drain the liquid from variator oil cooling radiator — it is integrated into the main system. Ignoring this step will result in mixing old and new antifreeze, which will shorten the life of the fluid.
Critical Feature: In models with air conditioning, part of the antifreeze remains in heat exchanger. To completely drain the fluid, you must disconnect the lower radiator hose. And Remove the hose from the heater (passenger side).
Step-by-step instructions for replacing antifreeze
Replacing antifreeze in Almera G15 does not require special equipment, but will require care. Here is the detailed algorithm:
- Preparation: Place the car on a flat surface, let the engine cool (antifreeze temperature should not exceed 50°C). Remove the expansion tank cap to relieve pressure.
- Draining old fluid:
- 🔧 Unscrew the drain plug on radiator (lower right corner).
- 🔧 Disconnect the lower radiator hose to speed up draining.
- 🔧 Drain the antifreeze from cylinder block (the plug is located under the exhaust manifold; a 14mm wrench is required).
MAX. Start the engine, warm it up to operating temperature (the fan will turn on), add fluid to the level.Purchase 7–8 liters of antifreeze (or 4 liters of concentrate + distilled water)|
Prepare a container for draining (volume of at least 8 l)|
Buy a new radiator drain plug (part no. 21410-4M000)|
Check the condition of the pipes and clamps (replace if necessary) |
Have on hand keys 10, 14 and a screwdriver to remove the protection (if any)
-->
Important nuance: After replacing the antifreeze, the first 2–3 days Monitor the level in the expansion tank. Due to the removal of air from the system, the level may drop - this is normal. Add fluid to the mark MAX.
If after replacing the antifreeze the heater blows cold air, it means there is air left in the system. To bleed it, remove the hose from the throttle body (from the intake manifold side) and add fluid until a bubble-free stream appears.
Signs that it's time to change antifreeze
Even if the scheduled time has not passed, antifreeze in Almera G15 requires replacement if the following symptoms occur:
- 🚨 Color change - if the green antifreeze has become rusty or cloudy, this is a sign of corrosion or additive development.
- 🚨 Sediment or flakes in the expansion tank - evidence of mixing of incompatible fluids or decomposition of additives.
- 🚨 Foam on the surface - indicates air or oil has entered the system (for example, through a broken cylinder head gasket).
- 🚨 Engine overheating If the fluid level is normal, the radiator or pump may become clogged.
- 🚨 Sweetish smell in the cabin - a sign of antifreeze leakage through the stove.
To check the condition of antifreeze you can use test strips (For example, Coolant Check from Liqui Moly). They show the pH level and additive content. If the pH is below 7.0 or above 10.5, the fluid must be replaced.
Antifreeze in Almera G15 loses its properties not only from time, but also from overheating, exposure to air or oil. Check its condition regularly - it's cheaper than engine repair!
Typical mistakes when replacing antifreeze
Even experienced car owners make mistakes that reduce the life of the cooling system. Here are the most common:
- Mixing different types of antifreeze. For example, topping up G12++ to original G11 from Nissan will lead to precipitation.
- Using tap water. Mineral salts in water form scale on the walls of the radiator and cylinder block.
- Incomplete drainage of old antifreeze. If the system is not flushed, the remaining fluid will shorten the service life of the new one.
- Ignoring air in the system. Air locks lead to local overheating of the engine and poor operation of the stove.
- Replacement without checking the pipes. Old hoses can burst under the pressure of new antifreeze.
Consequences of errors: Engine overheating, corrosion of aluminum parts, leaking radiator or pump. In the worst case - cylinder head deformation (especially relevant for HR16DE, where the block and cylinder head are aluminum).
Frequently asked questions (FAQ)
Is it possible to fill Almera G15 with G12++ antifreeze instead of the original one?
No, G12++ (red or purple) is not compatible with the original green antifreeze Nissan. It has a different additive package (organic acids instead of silicates) and can cause corrosion of aluminum parts. Use only LLC (Long Life Coolant) with markings Nissan LLC or Renault Type D.
How often should you check the antifreeze level?
B Almera G15 It is recommended to check the antifreeze level every month or before long trips. The level should be between the marks MIN And MAX on cold engine If the fluid leaves faster than 200–300 ml in 6 months, look for a leak (check the pipes, radiator, pump and cylinder head gasket).
What to do if antifreeze gets into the oil?
If antifreeze is mixed with oil (an emulsion appears on the dipstick and oil spots appear in the expansion tank), the car cannot be driven. This is a sign of a blown cylinder head gasket or a crack in the block/head. Required:
- Stop the engine immediately.
- Tow the car to a service center.
- Check the cylinder head gasket (part number
11044-4M000for HR16DE). - Change oil and antifreeze, flush the system.
The cost of repairs is from 15,000 ₽ (replacing the gasket) to 50,000 ₽ (if grinding of the cylinder head is required).
Is it possible to use antifreeze instead of antifreeze?
No, antifreeze (traditional domestic antifreeze) is not suitable for Almera G15. It has a different additive composition and temperature range. Antifreeze crystallizes already at -30°C (versus -40°C for the original antifreeze) and does not protect aluminum parts from corrosion. Its use will lead to:
- 🔸 Radiator blockage.
- 🔸 Engine overheating.
- 🔸 Corrosion of the pump and thermostat.
What kind of antifreeze is poured into the Almera G15 from the factory?
From factory to Nissan Almera G15 (2012–2019) filled green antifreeze Nissan Long Life Coolant (article KE902-99931). This not G11 in the usual sense, but a special liquid with an additive package for aluminum engines. Color - bright green, but it is not a determining factor (the composition is important).
