BMW Thermostats

BMW thermostats are known to fail, but luckily they typically fail wide open - meaning that your car can still cool. We offer thermostats from various OE suppliers we trust along with upgraded motorsport specific thermostats where applicable to make sure your BMW stays cool on track.

Plastic thermostat housing cracked on your M50?

Here are your choices: you can wait for the plastic factory thermostat housing cover to break and cause major overheating. (Even with a new stock cover, it won’t take long.) Or you can install a thoughtfully engineered all-aluminum thermostat housing cover from Active Autowerke and never experience this type of failure again. Currently there is no factory upgraded part to this problem. This is an aluminum extruded part that has all of the openings machine properly to fit like factory; from the mounting bolt holes, the seating of the thermostat to the sealing opening for the ORANGE gasket. Forged to exact factory tolerances, everything fits and this unit is a true easy bolt-on – especially suited for racing or load conditions like heavy traffic, where engine temp can rise rapidly. The housing is guaranteed never to break from overheating or over-tightening, and its CNC machined surface ensures a precise seat.

Unit comes complete with a new ORANGE sealing gasket; a new thermostat is recommended but not included.
For hotter climates, a 71 degree thermostat is recommended over the 82 degree unit.

Anything and everything BMW is the mantra at Active Autowerke. Since 1981 they have been serving the BMW community with custom turbocharger kits to a myriad of other innovative and inspiring performance parts.

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.

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.

It is important that your coolant system is serviced at regular intervals to ensure a long life. Over time, coolant systems are exposed to high temperatures and repeated thermal cycling, which causes warping, cracking, and hardening of plastics and rubber components in the coolant system. This can lead to coolant leaks and overheating, which can result in extensive engine damage if not resolved in a timely manner. This Water Pump & Thermostat kit helps to address a few of the most problematic parts, replacing these items entirely to keep your cooling system running optimally and efficiently.

It is important that your coolant system is serviced at regular intervals to ensure a long life. Over time, coolant systems are exposed to high temperatures and repeated thermal cycling, which causes warping, cracking, and hardening of plastics and rubber components in the coolant system. This can lead to coolant leaks and overheating, which can result in extensive engine damage if not resolved in a timely manner. This Water Pump & Thermostat kit helps to address a few of the most problematic parts, replacing these items entirely to keep your cooling system running optimally and efficiently.
