The BMW 520 series typically requires a specific type of coolant known as BMW Antifreeze/Coolant, which is usually a concentrated ethylene glycol-based formula. It is important to use the coolant that meets BMW's specifications, often identified as BMW Longlife Coolant (usually blue or green in color). Always check the owner's manual for the exact specifications and dilution ratios, as these can vary by model year. Additionally, mixing different types of coolant can lead to system issues, so it's best to stick with the recommended product.
