For a 2003 BMW 530i, it is recommended to use a BMW-approved coolant, specifically the BMW Antifreeze/Coolant (part number 82141467768) which is a mix of ethylene glycol and water. This coolant is designed to provide optimal protection against corrosion and overheating. Ensure you mix it with distilled water in a 50:50 ratio for best performance. Always check your owner's manual for specific recommendations and guidelines.
