What is the freezing point of Geely Emgrand's original antifreeze?

[HaileyLee]

Geely Emgrand's original antifreeze has a freezing point ≤-40°C, with a usage amount of 6.5L. Geely Emgrand antifreeze replacement cycle: The official recommended replacement cycle for Geely Emgrand antifreeze is once every year. Slowly turn the pressure cap counterclockwise. If you hear a hissing sound, wait until the sound disappears before opening. The hissing sound indicates that there is still pressure inside, continue turning the pressure cap and remove it. Pour the appropriate amount of coolant into the coolant expansion tank, with the coolant expansion tank cap open, start the engine and let it run, then reinstall the cap. Make sure the pressure cap is hand-tightened and fully seated. Function of antifreeze: It provides anti-corrosion protection for the components of the cooling system, prevents scale formation, and avoids reducing the heat dissipation effect of the radiator; it ensures the engine operates within the normal temperature range.

I previously researched the factory coolant of the Geely Emgrand, and its freezing point is generally set at around -40°C. This temperature is completely sufficient for most regions in China, especially during the cold winters in the north, ensuring reliable antifreeze performance. However, it's important to note that as the vehicle ages, the coolant's performance gradually degrades, and over time, the freezing point may not remain as low as it was initially. Therefore, it's best to check its condition every two years or after driving 30,000 to 40,000 kilometers to see if a replacement is needed. Additionally, when choosing coolant, don’t just go for the cheapest option or mix different brands casually. Different formulations can react chemically and form sediments, which may clog the small passages in the cooling system—definitely not worth the risk.

The factory-equipped antifreeze in the Emgrand typically has a freezing point of -40°C, which is sufficient for most domestic environments. However, I'd like to remind you about cost-saving in car maintenance: don't skimp on antifreeze. Many car owners believe meeting the freezing point standard is enough, but overlook the fact that antifreeze has a limited effective lifespan. The factory formula usually sees its antifreeze performance degrade after two to three years, with the freezing point potentially rising by 10°C or more. Moreover, antifreeze also serves anti-corrosion and anti-boiling functions. Long-term neglect can not only lead to radiator cracks in winter but also engine overheating in hot weather. Replacing an engine is far more expensive than changing antifreeze. It's advisable to follow the maintenance manual for regular replacements, and you can even ask the service center to test the actual freezing point before changing it.

As an engineering graduate, I've specifically researched the coolant parameters of the Emgrand: the factory-set freezing point of -40°C is the standard value. This parameter setting is quite thoughtful—it can handle the extreme cold of over -30°C in Harbin without compromising other performance by pursuing an ultra-low freezing point. However, I must remind you that the freezing point is not the only indicator; the boiling point under the cooling system's pressure is more critical. The OEM coolant's boiling point can exceed 120°C, ensuring thermal safety during aggressive driving. A friend of mine took a shortcut by adding tap water to top it off, which lowered the boiling point to around 100°C, causing the engine to overheat on the highway. Remember, if you find the fluid level below the standard mark, topping it up with the same OEM coolant is the safest option.
