Show original supplier description
The BMW OEM Auxiliary Water Pump is a direct replacement for the original component in select BMW G8X M2, M3, and M4 models. As a genuine OEM part, it guarantees the same quality and fitment as the original equipment installed at the factory. This auxiliary water pump plays a crucial role in the vehicle's cooling system. It circulates coolant not only to the engine and heater core but also to supporting systems like the turbocharger. This is particularly important for maintaining optimal operating temperatures during periods of low-speed driving or when the engine is at idle, where natural coolant flow might be insufficient. Symptoms of a failing auxiliary water pump can include engine overheating, especially under load or in stop-and-go traffic, visible coolant leaks from damaged seals or housing, and inconsistent or insufficient cabin heating. This specific pump is listed for various M2, M3, and M4 models from 2021-2025, as well as some 330e, 530e, 745e, X3, and X4 variants across different model years and engine configurations, often noted as being for the primary or secondary cooling system, or intercooler. It is recommended to research fitment with your vehicle's VIN to confirm compatibility, as part numbers and applications can vary.
