Antifreeze for Nissan Terrano: selection, replacement and common mistakes

Cooling system Nissan Terrano - a critical component on which the stability of the engine depends, especially in Russian frosts or city traffic jams. The wrong choice or untimely replacement of antifreeze can lead to corrosion of the radiator, overheating of the engine, or even failure of the pump. In this article we will look at which antifreeze is suitable for Terrano different generations, how to replace it correctly and what to look for when buying.

Models Nissan Terrano (including Terrano II And Terrano R500) have their own characteristics: for example, engines K9K (1.5 dCi) and MR20DD (2.0) require different types of coolant. We analyzed factory recommendations, owner reviews and technical nuances to create a checklist for a safe replacement. We'll also tell you why Antifreezes of different colors cannot be mixed and how to avoid air locks in the system.

Original antifreeze for Nissan Terrano: part numbers and composition

The manufacturer recommends using for Nissan Terrano coolant based on ethylene glycol with additive package Long Life Coolant (LLC). Original antifreeze from Nissan comes in two versions:

• 🔹 Nissan Coolant L248 Premix (article KE902-99932) - violet liquid ready for pouring, meets the standard JIS K 2234. Suitable for all petrol and diesel engines Terrano after 2014.
• 🔹 Nissan Coolant L250 Concentrate (article KE902-99931) - concentrate, requires dilution with distilled water in a 50/50 ratio. Used on the conveyor for the first fills.

Both options belong to the class hybrid antifreezes (G12+ according to VW classification) and contain organic and inorganic corrosion inhibitors. Service life of the original fluid - up to 5 years or 100,000 km, but when operating in difficult conditions (frequent overheating, low temperatures), it is recommended to reduce the interval to 3–4 years.

Important: in Terrano with engines K9K (diesel) original antifreeze has increased resistance to oxidation, since the operating temperature of the turbine is higher in these engines. Using non-original fluids without approval Renault-Nissan may lead to the formation of deposits in the head bores.

Analogues of the original antifreeze: what can be filled

If the original antifreeze is not available, analogues with identical specifications can be used. The main rule: the liquid must meet the standard Nissan MES N 2640-001 or Renault 41-01-001/-S Type D. The table below shows proven analogues indicating compatibility:

Brand and name	Article	Color	Compatible with Terrano	Notes
CoolStream Premium	CS010-04	Purple	Full (all engines)	Contains additives OAT (organic acids), service life up to 5 years
Motul Inugel Optimal	106365	Yellow	Partial (gasoline engines only)	Not suitable for diesel engines K9K due to low boiling point
Liqui Moly KFS 2001 Plus	8844	Red	Full (except for models before 2010)	Contains silicates, requires flushing the system when switching from G12+
Sintec Unlimited	G12++	Orange	Full	Lobrid antifreeze, compatible with aluminum radiators

⚠️ Attention: Antifreeze based propylene glycol (For example, Glysantin G40) are not recommended for Terrano, since they have a lower heat capacity and can cause engine overheating under high loads. Also avoid liquids with methanol - they are aggressive to the rubber pipes of the cooling system.

When choosing an analogue, pay attention to:

• 🔧 Manufacturer's approvals (must be indicated on the label).
• 🔧 Freezing point — optimal for Russia -40°C.
• 🔧 Service life - cheap antifreezes often require replacement after 2 years.

When and how often to change antifreeze in Nissan Terrano

The frequency of antifreeze replacement depends on the type of fluid, operating conditions and vehicle mileage. The manufacturer sets the following intervals:

• 📅 Original antifreeze (Nissan L248) - every 100,000 km or 5 years.
• 📅 Analogues of class G12+/G13 - every 80,000 km or 4 years.
• 📅 Cheap antifreeze (G11, antifreeze) - every 40,000 km or 2 years.

However, there are situations when replacement needs to be done ahead of schedule:

• 🚨 Appearance rust or flakes in the expansion tank.
• 🚨 Change the color of antifreeze to brown or cloudy.
• 🚨 Engine overheating for no apparent reason (may indicate a loss of liquid properties).
• 🚨 Antifreeze leak and refilling with another brand (complete replacement required).

For Nissan Terrano with a mileage of more than 150,000 km, it is recommended to reduce the replacement interval to 3 years, as deposits accumulate in the system, reducing cooling efficiency. It is also worth checking the condition pumps And thermostat — their wear is accelerated when using low-quality antifreeze.

How to check the condition of antifreeze without a laboratory?

Lower the test strip (for example, Coolant Tester) into the expansion tank. If the indicators show a pH below 7.0 or a high nitrite content, the fluid must be replaced.

Step-by-step instructions for replacing antifreeze

Replacing antifreeze in Nissan Terrano requires caution, since there are areas in the system where air pockets can form (for example, in a heater). To work you will need:

• 🔧 New antifreeze (8–10 liters for a complete replacement).
• 🔧 Distilled water (for rinsing).
• 🔧 Set of keys (including socket head) 10 mm for the drain plug).
• 🔧 Container for draining (volume of at least 10 liters).
• 🔧 Funnel and hose for filling.

Sequence of actions:

1. Drain old antifreeze.
   

   Place the car on a level surface and let the engine cool. Remove the expansion tank cap, then unscrew the drain plug on the radiator (lower right corner) and the plug on the cylinder block (with the key on 10 mm). Drain the liquid into a container.

2. Flushing the system.
   

   Pour distilled water through the expansion tank, start the engine and let it idle for 10-15 minutes. Drain the water and repeat the procedure 2-3 times until the drained liquid becomes clear.

3. Filling with new antifreeze.
   

   Reinstall the drain plugs and fill the antifreeze through the expansion tank to the mark MAX. Start the engine, turn on the heater to maximum temperature and fan speed. Add fluid as it decreases (the system will displace air).

4. Checking for air pockets.
   

   After filling, squeeze the upper radiator hose several times - this will help expel the air. Monitor the antifreeze level for a week after replacement.

⚠️ Attention: On Terrano with engine MR20DD (2.0 petrol) the drain plug on the cylinder block is located in an inconvenient location - it may be necessary to remove the starter for access. If you do not drain the fluid from the block, up to 1 liter of old antifreeze will remain in the system, which will shorten the service life of the new one.

Typical mistakes when replacing antifreeze and their consequences

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

• 🔥 Mixing different types of antifreeze.
  

  For example, topping up G11 (silicate) in G12+ (carboxylate) leads to the formation of a gel that clogs the radiator and engine channels. Consequence: overheating and repair of the cylinder head.

• 🔥 Use water instead of distilled water for dilution.
  

  Ordinary water contains salts that are deposited on the walls of the cooling system, reducing heat transfer. After 1–2 years, this can lead to corrosion of aluminum parts.

• 🔥 Incomplete drainage of old antifreeze.
  

  If more than 10% of the old fluid remains in the system, the properties of the new antifreeze deteriorate by 30–40%. Particularly critical for diesel engines Terranowhere residues can cause pump cavitation.

• 🔥 Ignoring air pockets.
  

  Air in the system leads to local overheating and ineffective operation of the stove. B Terrano Traffic jams often form in the heater and rear circuit (on all-wheel drive versions).

Another common mistake is antifreeze overflow above mark MAX. When heated, the liquid expands, and excess pressure can damage the expansion tank or pipes. The optimal level is 1–2 cm below the maximum mark.

How to check the quality of antifreeze in a Nissan Terrano

Over time, antifreeze loses its properties, even if it has not reached the specified service life. You can check its status in several ways:

1. Visual inspection.
   

   Open the cap of the expansion tank and evaluate the color of the liquid:

   • 🟣 Purple/pink - the norm for the original Nissan L248.
   • 🟠 Brown or cloudy - a sign of oxidation or mixing with another liquid.
   • ⚪ Foam or flakes - indicates oil ingress (cylinder head diagnostics required).

Density check.

Use a hydrometer (cost ~300 rubles). Antifreeze density should be within 1.073–1.085 g/cm³ at a temperature of +20°C. If the indicator is lower, the liquid is diluted with water; if it is higher, it is too concentrated (risk of freezing at -30°C).

Test strips.

Antifreeze test strips (e.g. Coolant Check) change color depending on the pH level and the content of inhibitors. If the indicator shows red color — the liquid has lost its protective properties.

For Nissan Terrano with a mileage of more than 100,000 km, it is recommended to check the antifreeze content annually iron and copper (using water analysis kits). Increased metal concentrations indicate corrosion in the system.

Frequently asked questions (FAQ)

Is it possible to use G13 (LOBrid) antifreeze in Nissan Terrano?

Yes, class antifreeze G13 (For example, VW G13 or CoolStream A-115) compatible with Terrano, but only with a complete replacement. They have a longer service life (up to 10 years) and better protect aluminum parts. However, the cost of G13 is 1.5–2 times higher than that of G12+.

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

If the service life is exceeded, antifreeze loses its anti-corrosion properties, which leads to:

• 🔧Destruction aluminum parts (radiator, cylinder head).
• 🔧 Clogging channels sediments (circulation worsens).
• 🔧 Accelerated wear pumps and thermostat.

In critical cases it is possible engine overheating and deformation of the block head.

What kind of antifreeze does the 2020 Nissan Terrano come from the factory?

On the assembly line in Terrano 2020 (and later releases) used Nissan Coolant L248 Premix purple color. This hybrid antifreeze (G12+) with additive package Long Life Coolant. Does not require dilution and is designed for 5 years of operation.

Is it possible to mix Nissan L248 antifreeze with CoolStream Premium?

Yes, these liquids have the same base (ethylene glycol) and compatible additives. However, mixing will shorten the life of the antifreeze by up to 3 years, since the balance of inhibitors is disrupted. It is recommended to carry out a complete replacement as soon as possible.

How much antifreeze is needed for a complete change in Terrano?

Cooling system volume Nissan Terrano depends on the engine:

• 🔧 K9K 1.5 dCi — 7.5 liters.
• 🔧 MR20DD 2.0 — 8.3 liters.
• 🔧 H4M 1.6 — 6.8 liters.

For a complete replacement with flushing you will need 10–12 liters (taking into account losses during draining).
