What is the boiling point of Shell antifreeze?

[BriellaDella]

The boiling point of Shell antifreeze is 106.5 degrees Celsius (at normal pressure). The key parameters for antifreeze are boiling point and freezing point - the lower the freezing point the better (e.g. -35°C is better than -30°C), while the higher the boiling point the better. The full name of antifreeze should be antifreeze coolant, meaning coolant with antifreeze function. Antifreeze prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block/head when parked in cold winter. Antifreeze is a special additive-containing coolant mainly used in liquid-cooled engine cooling systems. It has excellent properties including winter antifreeze protection, summer boil-over protection, year-round scale prevention, and corrosion resistance. Vehicle antifreeze generally needs replacement every 2 years or 40,000 kilometers - this is just a reference interval. For commercial vehicles with longer mileage, the replacement cycle should be shorter. Since each vehicle's operating conditions differ, replacement should be based on actual usage. Regularly check the antifreeze condition: replenish immediately if insufficient; if suspended matter, sediment, or deterioration/discoloration is observed, replace promptly and clean the system.

I checked the data on Shell's official website, and their antifreeze generally has a boiling point in the range of 110-130°C, depending on the specific model. For example, the commonly used Shell long-life antifreeze has a boiling point of about 112°C at 50% concentration, and it can reach 130°C at full concentration, which is significantly higher than pure water. The key point is that a higher boiling point means it's less likely to overheat during summer traffic jams. Last year, I encountered a major traffic jam on the highway, and the coolant temperature warning light didn't even come on—seems like choosing a high-boiling-point antifreeze was indeed a wise decision. Antifreeze also needs to consider the freezing point; preventing freezing at -35°C is crucial, especially in northern winters where temperatures often drop below -20°C.

I remember the technician mentioned during my last maintenance that Shell coolant has a boiling point starting at around 110°C, which is about ten degrees higher than my kettle's boiling point. For instance, the green OAT formula was tested at 113°C, while the orange one can reach about 125°C. The boiling point directly affects engine cooling—too high increases fuel consumption, and too low risks overheating. I always insist on using coolant with a boiling point above 110°C, especially since my older car's cooling system isn't the best. Also, a quick reminder: coolant should ideally be replaced every two to three years, and mixing different brands can lower the boiling point. A friend of mine mixed brands once, and the boiling point dropped to just over 100°C, nearly causing overheating during a long trip.

Shell coolant generally has a boiling point above 110°C, which can be categorized into three scenarios: the standard version around 110°C, the long-life type approximately 120°C, and reaching up to 130°C when fully concentrated. The key indicator is the ethylene glycol concentration, with the optimal boiling point achieved at a 50% water mixture. Last time I changed the coolant myself and tested the temperature, it withstood 110°C without issues. Don't just focus on the boiling point; the freezing point is more critical. Shell coolant can go down to -37°C, making it suitable for regions with winter temperatures as low as -25°C. After three to four years of use, the boiling point of coolant may drop by 5-8°C, so regular replacement is recommended.
