Choosing the right antifreeze for Nissan Almera G15 (2012-2019) is a task that requires attention to detail. Unsuitable coolant can lead to corrosion of aluminum engine parts, overheating, or even pump failure. In this article we will look at what kind of antifreeze was added from the factory?, which analogues are suitable for refueling or complete replacement, as well as nuances of the procedure that are not written about in standard instructions.

Models Almera G15 with engines HR16DE (1.6 l) and K4M (1.6 l, Renault) have different coolant requirements. For example, original antifreeze from Nissan for these motors the composition differs from what is recommended Renault for a similar unit. We analyzed factory manuals, owner reviews and laboratory test results to give clear recommendations - without general phrases or dubious advice.

Original antifreeze for Nissan Almera G15: part numbers and composition

From factory to Nissan Almera G15 coolant is poured based on ethylene glycol with additive package Long Life Coolant (LLC). It meets the specification Nissan Coolant L255 and has a characteristic green color (not to be confused with G11 or G12!). Important: original antifreeze Nissan not compatible with most universal type fluids G12+ or G13 due to differences in the composition of corrosion inhibitors.

Official articles of original antifreeze:

  • 🔹 KE902-99932 — concentrate (1 l), requires dilution with distilled water in a ratio of 50/50.
  • 🔹 KE902-99931 — ready-made liquid (1 l), already diluted to -37°C.
  • 🔹 KE902-99944 — concentrate (5 l), for complete replacement.

The composition of the original liquid includes:

  • 🧪 Ethylene glycol (base) - 90–95%.
  • 🧪 Additive package based on organic acids (OAT) free of silicates and borates.
  • 🧪 Green dye (does not affect properties, only for identification).
  • 🧪 pH balance: 7.5–8.5 (alkaline environment to protect aluminum).
⚠️ Attention: Antifreeze KE902-99932 often counterfeited. The original has a holographic sticker on the canister and a barcode that can be checked on the website Nissan. Counterfeits usually have a thinner consistency and a strong chemical smell.
📊 What antifreeze do you use in Nissan Almera G15?
  • Original Nissan (KE902-99932)
  • Analogue (for example, Ravenol, Motul)
  • Universal G12++/G13
  • I don't know what's in there

Analogues of the original antifreeze: what can be filled

If the original antifreeze Nissan not available, analogues with identical composition can be used. The main rule: the liquid must meet the specification Nissan L255 or Renault Type D (for engines K4M). Below are proven analogues used by dealers and service centers:

Brand Article Type Color Compatibility
Ravenol 4014835755007 JTC - Japanese Technology Coolant Green Full
Motul 105785 Inugel Optimal Green Full (for HR16DE)
CoolStream NRC Nissan/Renault Coolant Green Full
Liqui Moly 3676 Kuhlerschutz KFS 2001 Plus Green Partial (requires flushing)

Important: even among “compatible” analogues there are nuances. For example, Liqui Moly KFS 2001 Plus contains small amounts of silicates that can settle in the cooling system Almera G15 when mixed with original antifreeze. If you are planning a complete replacement, this option is suitable, but for refueling it is better to choose Ravenol JTC or Motul Inugel.

For engines K4M (Renault) antifreeze is also suitable Renault Glaceol RX Type D (article 7711428132). It is identical to the original Nissan composition, but has a yellow color. You can mix green and yellow antifreeze - The only difference is in the dye.

💡

Before purchasing an analogue, check its compatibility with aluminum radiators. Some "generic" antifreezes contain phosphates, which will destroy aluminum with prolonged use.

Antifreeze volume in the Almera G15 cooling system

Total volume of the cooling system Nissan Almera G15 depends on engine type and configuration:

  • 🔧 HR16DE (1.6 l, Nissan) — 6.7 liters (including expansion tank).
  • 🔧 K4M (1.6 l, Renault) — 6.2 liters.

When completely replacing antifreeze, it is usually possible to drain only 5.0–5.5 liters due to residues in the cylinder block and heater core. To flush the system you will need additional 8–10 liters of distilled water.

If you are planning a partial replacement (for example, if the level in the expansion tank drops), 1–1.5 liters of original antifreeze is enough. Important: do not add water or liquid of a different color - this will upset the balance of additives and lead to corrosion.

⚠️ Attention: In models with air conditioning, the volume of antifreeze may be 0.3–0.5 liters more due to the additional heat exchanger. Check the level after replacement with the engine running - it should be between the marks MIN And MAX on the expansion tank.

When to change antifreeze: regulations and signs of wear

Official regulations Nissan requires replacement of antifreeze every 90,000 km or 6 years (whichever comes first). However for Almera G15 with engine HR16DE this interval is often shortened to 60,000 km or 4 years due to the nature of the cooling system:

  • 🔥 High boiling temperature (up to 110°C) accelerates the breakdown of additives.
  • 🌀 Turbulent fluid movement in the channels of the cylinder block leads to increased wear of corrosion inhibitors.
  • 🚗 Operation in city mode (frequent warm-ups and stops) reduces the service life of antifreeze by 20–30%.

Signs that it’s time to change the antifreeze:

  • 🟢 Color change from green to brown or rusty.
  • 💨 The appearance of sediment or flakes in the expansion tank.
  • 🌡️ Frequent engine overheating (temperature rises above 95°C in traffic jams).
  • 🔊 Noise from the pump (a sign of cavitation due to loss of anti-foam properties).
What happens if you don't change the antifreeze?

Long-term use of old coolant leads to corrosion of aluminum parts (cylinder head, radiator), clogging of channels with decay products and failure of the thermostat. In critical cases, engine overheating and cylinder block deformation are possible.—>

To check the condition of the antifreeze, you can use test strips (for example, Motul Coolant Test Strips). They show the pH level and inhibitor content. If the pH is below 7.0 or the inhibitors are worn out by more than 50%, urgent replacement is required.

Step-by-step instructions for replacing antifreeze

Replacing antifreeze in Nissan Almera G15 requires care - there are many “air pockets” in the system that can lead to overheating if not removed. Below are step-by-step instructions, taking into account typical mistakes.

Required tools and materials:

  • 🔧 10 mm wrench (for radiator drain plug).
  • 🔧 Screwdriver with a flat blade (for pipe clamps).
  • 🔧 Funnel with a narrow spout.
  • 🔧 7-8 liters of distilled water (for rinsing).
  • 🔧 New antifreeze (6–7 liters).
  • 🔧 Drain container (minimum 10 l).

Procedure:

  1. Drain old antifreeze:
    • 📌 Place the car on a flat surface and let the engine cool (antifreeze temperature should be below 50°C).
    • 📌 Unscrew the expansion tank cap, then the drain plug on the radiator (lower right corner).
    • 📌 Remove the lower radiator pipe to speed up draining.
  2. Flush the system:
    • 📌 Pour distilled water through the expansion tank.
    • 📌 Start the engine and let it run for 5-7 minutes at idle speed.
    • 📌 Drain the water and repeat the procedure 2-3 times until the drained liquid becomes transparent.
  3. Fill with new antifreeze:
    • 📌 Install all plugs and pipes in place.
    • 📌 Fill antifreeze through the expansion tank to the mark MAX.
    • 📌 Start the engine and warm it up to operating temperature (the fan will turn on).
    • 📌 Add antifreeze to the level - when warmed up, the air will leave the system.

Make sure the engine is cold|Prepare a drain container with a volume of ≥10 l|Buy antifreeze with a reserve (7 l)|Check the tightness of the pipes and clamps

⚠️ Attention: Do not use ordinary tap water to flush the system - salts and minerals will settle in the radiator channels and worsen heat transfer. Also avoid "universal" acid-based washes - they can damage the plastic parts of the cooling system Almera G15.

Typical mistakes when replacing antifreeze and how to avoid them

Even experienced car owners make mistakes when replacing antifreeze, which later lead to serious problems. Here are the most common ones and how to prevent them:

1. Incomplete drainage of old antifreeze

In the cylinder block HR16DE Up to 1.5 liters of liquid remains, which cannot be drained by gravity. If you do not flush the system, the new antifreeze will mix with the old and its properties will deteriorate. Solution: use pneumatic compressor for purging the system through the expansion tank pipe.

2. Filling with antifreeze without removing air

Air locks in the cooling system Almera G15 lead to local overheating of the engine. To avoid this:

  • 🔹 After filling the antifreeze, remove the throttle heating hose and wait until bubble-free liquid comes out of it.
  • 🔹 Warm up the engine with the expansion tank cap open, periodically squeezing the radiator pipes.

3. Using inappropriate analogues

Many owners add antifreeze G12++ or G13, considering it "universal". However, these liquids contain carboxylateswhich are not compatible with the original additive package Nissan. Consequences: corrosion of aluminum parts and clogging of the heater radiator. Solution: Use only labeled antifreeze Nissan L255 or Renault Type D.

4. Ignoring leak testing

After replacing antifreeze, be sure to check the system for leaks:

  • 🔹 Inspect the pipes and clamps for cracks.
  • 🔹 Check the expansion tank cap - it should hold pressure 1.1–1.3 bar.
  • 🔹 Make sure the radiator drain plug is tightly tightened 1.5–2.0 Nm (do not overtighten!).

💡

The most critical mistake is mixing different types of antifreeze. Even if the colors match, the additive composition may be incompatible, which will lead to the formation of a gel and clogging of the radiator channels.

Frequently asked questions (FAQ)

Is it possible to mix green Nissan antifreeze with yellow Renault Type D?

Yes, these liquids are completely compatible in composition - the only difference is in the dye. Both meet specification Nissan L255 and do not contain silicates/borates. However, it is not recommended to mix them with other types (for example, G11 or G12+).

What antifreeze is installed in the 2018 Almera G15 from the factory?

Filled from the factory Nissan Coolant L255 (KE902-99932) — green, based on ethylene glycol with a package of additives OAT. For models with engine K4M (Renault) can be used Renault Glaceol RX Type D (yellow), which is identical in composition.

How much does original Nissan antifreeze cost for Almera G15?

Cost of original antifreeze KE902-99932 (1 l) in official dealership centers - 800–1200 rubles. Concentrate KE902-99944 (5 l) costs 3500–4500 rubles. Analogs (for example, Ravenol JTC) 20–30% cheaper.

What should I do if the engine gets hot after replacing the antifreeze?

Reasons for overheating after replacement:

  • 🔥 Air lock in the system (you need to bleed the air through the throttle hose).
  • 🔥 Faulty thermostat (check if it opens at 85–90°C).
  • 🔥 Clogged radiator (needs flushing or replacement).
  • 🔥 Incorrect antifreeze concentration (should be 50/50 with distilled water).

Is it possible to use antifreeze instead of antifreeze?

No, absolutely not possible. Antifreeze is an outdated ethylene glycol-based coolant with silicate additives that form deposits in the cooling system Almera G15. In addition, antifreeze has a lower boiling point (105°C versus 110–115°C for antifreeze L255), which will lead to engine overheating.
