What kind of antifreeze does a BMW use?
1 Answers
BMW requires the use of specialized antifreeze. The original BMW antifreeze is a glycol-based antifreeze with a high ethylene glycol content, accounting for more than 90%. When the concentration of ethylene glycol liquid is below 66%, its freezing point decreases as the concentration increases; however, when the concentration exceeds 66%, the freezing point increases with higher concentration. Generally, vehicle antifreeze should be replaced every 2 years or 40,000 kilometers, but this is only a reference interval. For commercial vehicles with higher mileage, the replacement interval should be shorter. Since driving conditions vary for each vehicle, the replacement should be based on actual usage. Check the antifreeze condition regularly—if the level is low, top it up promptly. If suspended particles, sediment, or discoloration are observed, replace the antifreeze immediately and flush the system. How to determine if antifreeze is low: Check the antifreeze warning light on the dashboard. If it illuminates, it likely indicates low antifreeze, though it could also be due to excessive engine temperature. Inspect the antifreeze reservoir. If the level is below the minimum mark (MIN), do not continue driving and add antifreeze promptly. Check the water level markings on the antifreeze tank. The normal antifreeze level should be between the MAX and MIN marks. If it falls below the MIN mark, it indicates a deficiency.
