2017-2020 BMW 330E 330I 340I 440I OEM Radiator
Direct OEM replacement radiator for modern BMW inline-six and four-cylinder engines. Purpose-built cooling performance without guesswork—bolt-in fit for your model year. Hard panel construction engineered to factory specifications.
Do I need to drain coolant before installation?
Yes. Drain your cooling system fully before removing the old radiator. Refer to your BMW service manual for drain procedures and coolant type — refill with the exact same spec to avoid corrosion issues.
What mounting hardware comes with this radiator?
The radiator assembly ships as pictured. Fastening hardware and hose clamps are not included — use your existing OEM hardware from the old unit, which typically transfers directly.
Is this radiator compatible with my cooling fans and shroud?
This radiator is engineered for OEM fitment, meaning your factory fan assembly and shroud mount exactly as they did before. No modification or adapter brackets needed.
