Using Prestone coolant in your BMW X5 is not recommended, as BMW vehicles typically require a specific type of coolant that meets their standards, often a phosphate-free formula designed for their engines. Using the wrong coolant can lead to corrosion, reduced performance, and potential damage to the cooling system. It’s best to use BMW-approved coolant to ensure optimal performance and longevity of your vehicle. Always consult your owner’s manual for the manufacturer’s specifications.
