Where to Add Coolant for BMW 5 Series?

[AndrewLee]

Open the vehicle's engine hood, and you will find a black reservoir on the left side of the engine. Open the reservoir cap to add coolant. Additional Information: 1. The coolant for BMW 5 Series should generally be replaced once a year, or for vehicles with shorter operating times, every two years or every 30,000 kilometers. When adding coolant to the BMW 5 Series, the fluid level should be between the MAX and MIN marks. 2. Be careful not to mix different types of antifreeze. Different types of antifreeze have different freezing points due to their varying compositions, so 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.
