Car antifreeze can generally last for two years, while some long-life antifreeze can have a shelf life of up to 5 years. Antifreeze that exceeds its shelf life may deteriorate, produce impurities, and some of its internal chemical components may become ineffective, which can have a certain degree of impact on the cooling system or engine, making it unusable. The full name of car antifreeze is antifreeze coolant, meaning it is a coolant with antifreeze function, which can prevent the coolant from freezing and cracking the radiator or freezing the engine cylinder block or head when the car is parked in cold winter. Antifreeze is a type of coolant containing special additives, mainly used in liquid-cooled engine cooling systems, with excellent properties such as antifreeze in winter, anti-boil in summer, and anti-scale and anti-corrosion all year round.

What is the minimum age for the front passenger seat?

The minimum age for the front passenger seat is 12 years old. Here are the specific details: 1. Safety concerns: In the event of sudden braking, parents may not be able to provide timely protection for children in the front passenger seat. Car seat belts are designed according to adult standards and are suitable for individuals weighing 36kg and with a height of 140cm or more. Children have smaller physiques and immature bones, and in the event of a collision, the front airbags can cause harm to them. In dangerous situations, the driver may instinctively avoid impact, leading to the front passenger seat being hit and causing injury to the passenger. 2. Legal aspects: When driving a motor vehicle on the road, it is prohibited to arrange for minors under the age of twelve to sit in the front passenger seat. When a motor vehicle is in motion, both the driver and passengers must use seat belts as required by regulations.
