Do I need to flush my cooling system before installing this radiator?
Flushing is recommended to remove sediment and old coolant before swapping in a new radiator. Clean system extends radiator life and prevents blockages. Your BMW service manual details the flush procedure for your specific model year.
Will this radiator work with my current coolant, or do I need BMW-spec fluid?
BMW turbo models use specific coolant formulations to handle high heat loads. Stick with OEM-approved coolant or equivalent long-life BMW coolant to protect the radiator and engine. Check your owner's manual for the exact spec.
