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.

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.
