This genuine OEM BMW thermostat (part 7646665) came from a used donor vehicle. The thermostat regulates coolant flow to maintain proper engine operating temperature—when it fails, you may see engine overheating, inconsistent cabin heat, or a check engine light related to cooling system performance. It was removed from a BMW X5 equipped with the 2.0L 1997CC I4 PHEV turbocharged engine. This is a single used OEM unit with no superseded numbers on record.
