What brand of antifreeze should be used for BMW 5 Series?
1 Answers
There is no mandatory regulation on the brand of antifreeze, and using the same brand of antifreeze is sufficient. Different brands of antifreeze may have varying production formulas, and mixing them could lead to chemical reactions between multiple additives, rendering them ineffective. How to choose antifreeze: The basic indicators of antifreeze are the freezing point and boiling point. On the market, antifreeze is available with freezing points of -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose one that is at least 10°C lower than the lowest temperature in your region. How to determine if antifreeze is low: Observe the antifreeze warning light on the dashboard. If it lights up, it is likely due to low antifreeze levels, though it could also be caused by excessively high engine temperature. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving and promptly add antifreeze. Check the water level scale on the antifreeze tank. The normal antifreeze level should be between the maximum and minimum marks. If the antifreeze level is below the minimum mark, it indicates a shortage of antifreeze.
