Modern BMW thermostats are electronically controlled, allowing the DME/ECU to directly regulate coolant flow throughout the engine and its components. This system enables the thermostat to operate based on a broader range of temperature inputs, such as coolant, cylinder head, engine block, and oil temperatures, for more refined control of engine warm-up and temperature across diverse conditions. Unlike traditional thermostats, which simply open or close to permit coolant flow, this system uses a rotary valve for more dynamic control. The rotary valve adjusts to various positions, allowing for partial or full coolant flow to designated passageways as needed. This precision control helps your BMW's engine reach optimal temperatures quickly and ensures efficient heat management under various driving conditions.

The cooling system has always been a weak point for BMW. Two of the biggest issues are the water pump and thermostat. This continues to be true even on the newest B-Series engines found in 2016+ BMWs. This kit includes a brand new Genuine BMW water pump, a new thermostat (now referred to as a Heat Management Module), and 1 gallon of BMW's G48 coolant concentrate (makes 2 gallons of 50/50 coolant). Don't spend thousands of dollars at the dealership, these can easily be replaced in an afternoon with basic mechanic's tools.

Engine running a little hot or is the temp gauge not telling you anything? The thermostat might be the likely problem. Many cooling issues start with the thermostat. This is electronically controlled by the engine computer based on the cooling demands from the engine. And cooling components are working harder than ever. Engine performance is also dependent on temperature - as temperatures rise and pass a certain threshold the engine computer will begin reducing power. Stay on top of your cooling maintenance by replacing critical components preventatively.
