Crossover Nissan Murano third generation (Z51, 2015–2026) is equipped with modern gasoline engines VQ35DD (3.5 L) and a hybrid system (in some markets). The correct choice and timely replacement of antifreeze for this model is a critically important procedure that affects the life of the engine, radiators and pump. Unlike previous generations, Murano Z51 requires use specialized coolants with a unique additive package compatible with aluminum blocks VQ-series and a direct injection system.

In this article we will analyze all the nuances: from original antifreeze Nissan to proven analogues, filling volumes for different types of engines, as well as step-by-step replacement instructions taking into account the specifics Z51. We will pay special attention risks of mixing liquids with different standards (e.g. Type D And Type E), which can lead to corrosion of cylinder liners after 20–30 thousand km.

Original antifreeze for Nissan Murano Z51: articles and standards

The manufacturer recommends using exclusively standard coolant Nissan Long Life Coolant Type E (blue color). This antifreeze is designed specifically for engines with aluminum alloys and direct injection systems that are installed on Murano Z51. Main articles of original liquids:

  • 🔹 KE902-99932 — concentrate Type E (1 l), requires dilution with distilled water in a 50/50 ratio.
  • 🔹 KE902-99931 — ready-to-use liquid (1 l).
  • 🔹 KE902-99944 — concentrate for regions with extremely low temperatures (down to -50°C).

Important: don't confuse Type E with outdated Type D (green)! The latter contains silicates, which over time form abrasive deposits in the channels of the cooling system VQ35DD. Original Type E has an extended service life - up to 120 thousand km or 6 years (whichever comes first).

⚠️ Attention: At dealerships Nissan They often offer universal antifreeze Coolant L250 (article KE902-99935) for all brand models. However for Murano Z51 it is only suitable as a last resort - its additives are less effective at protecting aluminum at high temperatures.
Article Type Color Volume, l Notes
KE902-99932 Concentrate Type E Blue 1 Dilute with distilled water 1:1
KE902-99931 Ready liquid Type E Blue 1 Refill without dilution
KE902-99944 Concentrate for cold climates Blue 1 Withstands down to -50°C
KE902-99935 Coolant L250 Green 1 Not recommended for Z51

Analogues of the original antifreeze: what can be poured into Murano Z51

If original Type E not available, the use of analogues from trusted manufacturers that meet specifications is allowed Nissan. The main requirement is compatibility with aluminum alloys and the absence of silicates (silicate-free). Best options:

  • 🔧 CoolStream A-110 (Russia) - fully compatible with Type E, has permission Nissan.
  • 🔧 Ravenol HJC Hybrid Japanese Coolant (Germany) - universal for Japanese cars, blue color.
  • 🔧 Motul Inugel Optimal (France) - silicate-free formula, suitable for VQ35DD.
  • 🔧 Peak OET Extended Life (USA) - analogue Type E, sold ready-made.

When choosing an analogue, be sure to check for certificates JIS K 2234 (Japanese standard) or ASTM D3306. Avoid ethylene glycol based fluids with silicates (G11) or carboxylate (G12+), if they do not have direct access Nissan. For example, popular Felix Carbox G12+ may cause corrosion in the cooling system Murano Z51 due to incompatibility of additives.

Antifreeze volume in the cooling system Murano Z51

The total volume of coolant in Nissan Murano Z51 depends on engine type and configuration:

  • 🚗 Petrol VQ35DD (3.5 l, 249 hp) — 9.5–10.0 l (including heater radiator).
  • 🚗 Hybrid version (2.5 l + electric motor) — 8.2–8.7 l.

When partial replacement (drain through the lower radiator pipe) about 5–6 l new antifreeze. For complete replacement with flushing will be required 12–14 l fluid (taking into account the residues in the engine block).

⚠️ Attention: In hybrid versions Murano Z51 The cooling system is divided into two circuits: for the internal combustion engine and for the inverter/batteries. Antifreeze in these circuits different! The inverter uses a special liquid Nissan EV Coolant (article KE902-99945), mixing it with regular antifreeze is strictly prohibited.

Before purchasing antifreeze, check the label for the words "Hybrid Vehicle Compatible"is a guarantee of compatibility with hybrid systems Murano Z51.

When to change antifreeze Nissan Murano Z51: regulations and signs of wear

Official regulations Nissan provides for replacing antifreeze every 120 thousand km or 6 years (whichever comes first). However, in real operating conditions (especially in cities with traffic jams or hot climates), this interval should be reduced to 90–100 thousand km. Signs that the liquid has lost its properties:

  • 🔥 Darkening of color (from blue to brown or rusty).
  • 🔥 The appearance of sediment or flakes in the expansion tank.
  • 🔥 Frequent activation of the cooling fan at normal temperatures.
  • 🔥 Drop in liquid level without visible leaks (evaporation of additives).

To check the condition of antifreeze you can use test strips (For example, Coolant Check from Liqui Moly). They show the level of corrosion protection and freezing point. If the bar shows pH below 7.0 or crystallization temperature is higher -35°C, the fluid requires urgent replacement.

What happens if you don't change the antifreeze?

Long-term use of old fluid leads to:

- Corrosion of cylinder liners (especially in the area of contact with the coolant).

- Clogging of the radiator channels and heater stove (deterioration of heat transfer).

- Accelerated wear of the pump (abrasive particles in the liquid destroy the seal).

- Engine overheating due to reduced thermal conductivity.

Step-by-step instructions for replacing antifreeze in Murano Z51

To replace you will need:

  • 🛠️ New antifreeze (10–12 l for a complete replacement).
  • 🛠️ Distilled water (5 l for washing).
  • 🛠️ Set of keys (head on 10 mm for the drain plug).
  • 🛠️ Funnel and hose for pouring.
  • 🛠️ Container for draining (minimum 10 l).

Procedure:

  1. Draining old antifreeze:

    Place the car on a flat surface, lift the front part (you can use a jack or overpass). Remove the engine protection (if equipped). Place a container under the radiator drain plug (located in the lower right corner). Unscrew the plug with the key to 10 mm and wait until it drains completely. Then unscrew the plug on the engine block (on the right side to the oil filter) - this will allow the residue to drain from the cooling jacket.

  2. Flushing the system:

    Close the drain plugs and fill the expansion tank with distilled water to the maximum. Start the engine and let it run 10–15 minutes at idle speed (turn the heater to maximum). Drain the water and repeat the procedure 2-3 times until the drained liquid becomes 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, warm it up to operating temperature (the fan should turn on 2-3 times). Add antifreeze to the level - the system will “bleed” on its own.

⚠️ Attention: B Murano Z51 after replacing antifreeze necessarily need to clear the error P0597 (low coolant level) via diagnostic scanner. Otherwise the dashboard will light up Check Engine, despite the normal level.

Typical mistakes when replacing antifreeze and how to avoid them

Even experienced car owners make mistakes that can lead to serious damage. Let's look at the most common ones:

  • ❌ Mixing different types of antifreeze. For example, topping up Type D (green) in Type E (blue) causes a chemical reaction leading to the formation of a gel that clogs the heater radiator.
  • ❌ Using tap water. Salts and impurities in water form scale on the walls of the channels, impairing heat transfer.
  • ❌ Incomplete drainage of old antifreeze. Remains of the old fluid reduce the service life of the new one by 30–40%.
  • ❌ Ignoring flushing. Without washing, new additives will not be able to fully protect the metal.

Another common problem is air jams. B Murano Z51 they form at the top point of the system (near the throttle valve). To remove them, after adding antifreeze you need to:

  1. Warm up the engine until the fan turns on.
  2. Turn off the engine and let cool for 10 minutes.
  3. Open the expansion tank cap and squeeze the upper radiator hose with your hand (air will escape).
  4. Add antifreeze to the level MAX.
💡

Never pour antifreeze “by eye” - into Murano Z51 It is critical to observe the proportions of dilution of the concentrate. Exceeding the proportion of water reduces the boiling point of the liquid, which can lead to overheating of the engine in traffic jams.

Frequently asked questions (FAQ)

Is it possible to mix antifreeze? Type E with Type D in Murano Z51?

No, mixing them is strictly prohibited. Type D contains silicates that react with organic additives Type E, forming gel-like deposits. This leads to clogging of the heater radiator and overheating of the engine. If you had to top up with another type, perform a complete replacement with flushing as soon as possible.

What kind of antifreeze is poured in from the factory? Murano Z51 2023?

From factory to all Murano Z51 (including restyled models 2022–2026) filled Nissan Long Life Coolant Type E blue color. This fluid does not require replacement first 120 thousand km, but only on condition that the system is sealed and there have been no top-ups from other brands.

What to do if it lights up after replacing the antifreeze Check Engine?

In 90% of cases this is an error P0597 (low coolant level). It appears due to the release of pressure in the system after replacement. To eliminate it, you need:

  1. Warm up the engine to operating temperature.
  2. Stop the engine and open the expansion tank cap.
  3. Add antifreeze to the mark MAX.
  4. Connect a diagnostic scanner (for example, Launch X431) and reset the error.

If the error appears again, check the system for leaks (there may be a leak through the thermostat gasket or a crack in the expansion tank).

How much does it cost to replace antifreeze at a service center? Murano Z51?

Cost of work at official dealers Nissan amounts to 3,500–5,000 rubles (excluding the cost of liquid). In independent services the price is lower - 2,000–3,000 rubles. However, saving on work can lead to problems: for example, not all services flush the system before replacement, which shortens the service life of the new antifreeze.

Can antifreeze be used? G12++ or G13 instead of Type E?

Theoretically, antifreeze class G12++ or G13 (For example, Liqui Moly KFS 2001 Plus) have similar characteristics to Type E. However Nissan does not give official approval for these liquids in Murano Z51. Risks of use:

  • Incompatibility of additives with aluminum alloy block VQ35DD.
  • Reduced pump life due to a different composition of lubricating additives.
  • Loss of engine warranty (if the car is under warranty).

If you still decide to fill G12++, select products marked "Japan Spec"and change the fluid every 60 thousand km.
