What is the model number of the antifreeze for the Nissan Teana?

The model number of the antifreeze for the Nissan Teana is L255N, and its color is blue. The method for replacing the antifreeze is as follows: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with a particular focus on the five-way water pipe. The antifreeze flows through the five-way pipe and is then distributed to different parts of the car to function. If there is any leakage of antifreeze in this section, replace the water pipe or re-secure the connection as needed. Drain the old antifreeze, then flush the liquid channels with clean water. Add clean water to the antifreeze reservoir, then continuously inject water into the reservoir so that it flows through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water flowing out of the reservoir will have a faint pink color. Continue adding clean water until the water coming out is clear. Note: Remember to remove the heater hose and drain the water from the heater core. After draining for about an hour, add the new antifreeze through the radiator hose. Then, add another container of antifreeze to the antifreeze reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. At this point, the coolant level will drop slightly as air is purged from the system. Add more antifreeze until the level reaches the "MAXT" mark on the reservoir.
For the Nissan Teana, it is recommended to use Nissan's genuine long-life coolant, typically the blue one, known as Nissan Genuine Long Life Coolant. From my frequent maintenance of Nissans, I've found this to be the most reliable. It is based on organic acid technology, effectively preventing freezing and rust while maintaining stable engine temperature. Replace it every two years or 30,000 kilometers, and avoid mixing with other types to prevent gelation and blockages. If the genuine product is unavailable, compatible brands like Prestone Blue Label can be used, but always check the manual specifications. Regularly inspect the fluid level and color changes to prevent overheating issues. Remember, using the correct type ensures the cooling system's durability—don't cut corners and take risks.
My Altima has been in use for five years, and the manual specifies the original coolant model as a blue-green version starting with something like KLC. I went to the dealership and bought the premixed version, which was quite convenient to top up myself. I feel the original coolant has excellent high-temperature resistance and prevents radiator corrosion. Normally, I change it every three years, and if the level is low, I top it up with a distilled water mixture instead of adding pure water. I've had the experience of mixing different brands leading to leaks, so now I stick only to the Nissan-recommended model to avoid expensive radiator repairs. Coolant isn't just for winter; it's also crucial for preventing boiling in summer.
