<p>This BMW Electric Cooling Fan (850w) — OEM part number 7634471 — is a used genuine factory component, removed from a donor vehicle. Also called an electric fan or radiator fan, it moves air through the radiator and condenser to prevent overheating. When failing, the fan may not spin, causing high coolant temperatures or weak AC performance. This 850-watt unit fits 2.0L PHEV, 3.0L turbo gas, and 3.0L turbo diesel engines from certain BMW X5 and X6 models.</p><p><strong>Fits:</strong> BMW X5 (2014-2018), BMW X6 (2015-2019)</p><p><strong>OEM part number:</strong> 7634471.</p><p><strong>Condition:</strong> Used OEM, pulled in-house from a donor vehicle scanned with factory diagnostic tools; tested where possible, with per-part condition notes. 30-day returns.</p>
