Original BMW Coolant Pump with Thermostat and Support for BMW X1 and Mini Cooper, Cooper Clubman, and Cooper Countryman (2014–2019)

Combining the water pump, thermostat, and mounting bracket in one unit, Original BMW coolant pump 11-51-8-601-366 circulates and regulates engine coolant on the BMW X1 and the Mini Cooper, Cooper Clubman, and Cooper Countryman across model years 2014–2019, depending on the car. BMW calls the part the coolant pump with thermostat and support, and the complete assembly weighs 2.8 kg (6.1 lb). Production of this number began in December 2013. The pump moves coolant through the engine and out to the radiator, while the thermostat holds coolant in the engine until it warms up and then opens the path to the radiator. Because all three pieces come as a single part, the pump, thermostat, and bracket are renewed together in one job.

Original BMW Parts on this assembly carry a 24-month parts warranty.

BMW applies this assembly to the F48 X1 across the B38, B42, B46, B48, and B32 engines. It replaces the earlier part number 11-51-8-623-576, and BMW rates that change as exchangeable retrospectively, so the newer assembly can go onto cars first built with the older part.
