Where to Add Coolant in a BMW?

[EvangelineMarie]

Open the hood, and you'll find a black reservoir on the left side of the engine. Unscrew the cap to add coolant. Here’s some relevant information: 1. The full name of coolant is antifreeze coolant, which has antifreeze properties. Coolant is not only used in winter but also throughout the year. Whether it's cold or hot, a car cannot operate without coolant. Proper use of coolant not only protects the engine's cooling system and improves heat dissipation but also enhances engine efficiency and extends its service life. 2. Be careful not to mix different types of antifreeze. Different types of antifreeze have varying freezing points due to their different compositions, so you should choose based on the temperature conditions of your driving environment. Generally, the freezing point of the antifreeze should be 10-15°C lower than the local minimum temperature to prevent the antifreeze from losing its functionality.
