How many liters of coolant are needed for a BMW replacement?

[VonRonan]

Replacing the coolant in a BMW requires 6.5 liters. Coolant is a type of cooling liquid containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion throughout the year. Can different brands of coolant be mixed: It is necessary to use the same brand of coolant. Different brands of coolant may have varying production formulas. Mixing them could lead to chemical reactions between multiple additives, rendering them ineffective. How to determine if there is a shortage of coolant: Observe the coolant warning light on the dashboard. If it lights up, it is likely due to a shortage of coolant, although it could also be caused by excessively high cylinder temperatures. Check the coolant reservoir. If the liquid level is below the minimum mark (MIN), do not continue driving and add coolant promptly. Inspect the water level scale on the coolant tank. The normal coolant level should be between the maximum and minimum marks. To check if there is a shortage, observe the scale. If the coolant is below the minimum mark, it indicates a shortage.
