Nissan Primera P12 (2001–2007) - a car that is still popular due to its reliability and unpretentiousness. However, even the most reliable machine requires timely maintenance, and the cooling system is no exception. Antifreeze in Primera P12 not only prevents engine overheating, but also protects metal parts from corrosion and rubber seals from cracking.
In this article we will look at what antifreeze is suitable for Nissan Primera P12, how to choose it correctly, when to change it and what nuances to consider when replacing it. We will also answer frequently asked questions from owners, including compatibility with analogues and the consequences of using the wrong liquid.
Original antifreeze for Nissan Primera P12: what the factory filled
From factory to Nissan Primera P12 (with gasoline engines QR20DE, QR25DE and diesel YD22DDTi) filled with standard antifreeze Nissan Long Life Coolant (L248) - green. This liquid belongs to the class hybrid antifreeze (HOAT)containing both organic and inorganic corrosion inhibitors.
Original antifreeze from Nissan has a catalog number KE902-99932 (concentrate) or KE902-99931 (ready to use). Its key features:
- 🔹 Service life: up to 5 years or 100,000 km (depending on operating conditions).
- 🔹 Temperature range: from –37°C to +129°C (when diluted 50/50 with distilled water).
- 🔹 Compatibility: Suitable for all aluminum and cast iron engines Nissan that period.
Important: original antifreeze Nissan L248 not compatible with most modern carboxylate (OAT) antifreezes due to different additive compositions. Mixing may cause sediment to form and clog the radiator.

Analogues of the original antifreeze: what can be filled instead of L248
If the original antifreeze Nissan It is difficult to find or it is too expensive; you can use high-quality analogues with a similar composition. Main rule: fluid must meet specification Nissan L248 or JIS K 2234 (Japanese standard for antifreeze).
Proven analogues:
- 🔧 Coolstream Premium (green, HOAT) - complete analogue in composition, suitable for long-term protection.
- 🔧 Ravenol HJC Hybrid Japanese Coolant - hybrid antifreeze, compatible with Nissan And Toyota.
- 🔧 Motul Inugel Optimal - a universal option, but requires checking for compatibility with the existing liquid.
- 🔧 Total Glacelf Auto Supra — suitable for Japanese and Korean cars, but it is not recommended to mix with other brands.
⚠️ Attention: Do not use antifreeze grades G12+ or G13 (propylene glycol based) without pre-flushing the system. They are incompatible with the original fluid Primera P12 and may cause corrosion of aluminum parts.
| Antifreeze brand | Type | Color | Service life | Compatible with L248 |

Antifreeze volume in the Primera P12 cooling system
The total volume of coolant in Nissan Primera P12 depends on engine type and configuration:
- 🔰 Gasoline engines
QR20DE(2.0 l) andQR25DE(2.5 l): 6.7–7.0 liters. - 🔰 Diesel engine
YD22DDTi(2.2 l): 7.5–8.0 liters (due to additional gas recirculation cooler).
When completely replacing antifreeze, it is usually possible to drain 5.5–6.5 liters (the remainder remains in the cylinder block and heater core). To flush the system you will need additional 5–10 liters of distilled water.
⚠️ Attention: If, after draining the old antifreeze, its volume is less than 5 liters, this may indicate air pockets or a clogged system. In this case, diagnostics of the pump and radiator is required.
Before replacing antifreeze, warm up the engine to operating temperature (90°C) - this will help open the thermostat and drain the maximum amount of old fluid.
When to change antifreeze in Nissan Primera P12: signs and timing
The manufacturer recommends replacing antifreeze in Primera P12 every 5 years or 100,000 km (whichever comes first). However, in real operating conditions (especially in cities with hot climates or frequent traffic jams), this interval can be reduced to 3–4 years.
Signs that antifreeze has lost its properties:
- 🚨 Color change (darkening, appearance of a rusty shade).
- 🚨 Formation of flakes or sediment in the expansion tank.
- 🚨 Frequent overheating of the engine during normal fan operation.
- 🚨 Foam on the surface of the liquid (a sign of air entry or the development of additives).
To check the condition of antifreeze you can use test strips (for example, from Motul or Liqui Moly), which indicate the level of corrosion protection and freezing point. If the pH of the liquid is below 7.0 or above 10.5, urgent replacement is required.
What happens if you don't change the antifreeze?
Long-term use of old fluid leads to corrosion of aluminum parts (cylinder head, radiator), clogging of cooling channels and overheating of the engine. In critical cases, this can cause cylinder head deformation or gasket failure.—>
Step-by-step instructions for replacing antifreeze in Primera P12
Replacing antifreeze in Nissan Primera P12 does not require special equipment, but will require care. It is better to carry out the procedure in a pit or overpass.
Required materials and tools:
- 🛠️ New antifreeze (7-8 liters for a complete replacement).
- 🛠️ Distilled water (10-15 liters for rinsing).
- 🛠️ Set of keys (10, 14 for drain plugs).
- 🛠️ Container for draining (minimum 10 liters).
- 🛠️ Funnel and hose for pouring.
- 🛠️ Gloves and rags.
Procedure:
- Drain old antifreeze:
- Place the car on a level surface and let the engine cool.
- Remove the expansion tank cap (to relieve pressure).
- Place a container under the drain plug on the radiator (lower right corner) and unscrew it with a 14 mm wrench.
- Unscrew the plug on the cylinder block (key 10, next to the oil filter).
- Flush the system:
- Close the drain plugs and fill with distilled water to the maximum.
- Start the engine and let it idle for 10–15 minutes.
- Drain the water and repeat the procedure 2-3 times until the liquid is clear.
- Add new antifreeze:
- If using concentrate, dilute it with distilled water in a 50/50 ratio.
- Fill liquid through the expansion tank to the mark
MAX. - Start the engine, warm it up until the fan turns on, add antifreeze if necessary.
☑️ Checklist before replacing antifreeze
⚠️ Attention: After replacing the antifreeze, monitor the level in the expansion tank for the first 2–3 days. Air pockets can squeeze out fluid, so topping up will be required.
Common mistakes when replacing antifreeze and how to avoid them
Even experienced car owners sometimes make mistakes that lead to problems with the cooling system. Let's look at the most common ones:
1. Mixing incompatible antifreezes
As already mentioned, Do not mix HOAT (green) with OAT (red/orange). This leads to sedimentation and clogging of the radiator. If you don’t know what was uploaded earlier - flush the system.
2. Incomplete drainage of old antifreeze
Up to 1–1.5 liters of liquid remain in the cylinder block and heater radiator. If you do not flush the system, the new antifreeze will mix with the old and its properties will deteriorate. Solution: rinse until clean water.
3. Ignoring air pockets
Air in the system leads to overheating of the engine and uneven heating of the interior. To avoid traffic jams:
- 🔄 After filling the antifreeze, squeeze the upper radiator pipe several times.
- 🔄 Warm up the engine with the reservoir cap open, adding fluid.
4. Using tap water
Tap water contains salts and impurities that form scale. Distilled water only to dilute the concentrate!
FAQ: Frequently asked questions about antifreeze in Nissan Primera P12
Is it possible to fill Primera P12 with G12 or G13 antifreeze?
No, these antifreezes (ethylene glycol or propylene glycol based) are not compatible with the original fluid. Nissan L248. They can only be used after complete flushing of the system and replacing all rubber seals (they may swell due to a different composition).
What antifreeze should I fill in a Primera P12 with a YD22DDTi diesel engine?
The same applies to diesel versions Nissan L248 or its analogues (for example, Coolstream Premium). The volume of the system is larger (up to 8 liters), so an additional canister will be required.
What should I do if the antifreeze in the Primera P12 runs out quickly?
Reasons for leakage:
- 🔧 Cracks in the expansion tank or pipes.
- 🔧 Leaking from under the pump (a characteristic sign is a wet spot under the pulley).
- 🔧 Cylinder head gasket failure (white smoke from the exhaust, oil emulsion in the tank).
Solution: visual inspection, checking the pressure in the system (you can use a compressor with an adapter).
Is it possible to mix antifreeze of different colors?
Color is not an indicator of compatibility! For example, green Coolstream (HOAT) can be mixed with original Nissan L248, but not with green Felix (G11). Always check composition and standard on the packaging.
How to check the quality of antifreeze without test strips?
Simple ways:
- 🔍 Visually: Cloudy color, sediment or flakes are a sign of aging.
- 🔍 Smell: A strong chemical smell indicates additive production.
- 🔍 Foam when shaken: If the foam does not settle for more than 3-5 seconds, the antifreeze has lost its properties.
