1 Answers
BMW 5 Series coolant adding method: After opening the car hood, there is a black reservoir on the left side of the engine. Open the reservoir cap to add coolant. The full name of coolant is antifreeze coolant, which has antifreeze function. The following is a detailed introduction to coolant: 1. Coolant can not only protect the engine cooling system and improve heat dissipation efficiency, but also enhance engine performance and extend its service life. 2. Coolant should generally be replaced once a year, while vehicles with shorter running times can replace it every two years or every 30,000 kilometers. 3. When adding coolant, the liquid level should be between the MAX and MIN marks. 4. Be careful not to mix different types of coolant. Due to different compositions, different types of coolant have different freezing points, so choose according to the temperature conditions of the vehicle's operating environment. Generally, the freezing point of the selected antifreeze should be 10-15°C lower than the local minimum temperature to prevent the antifreeze from losing its antifreeze function.
