Water Pump & Thermostat Kit - Gen 1 B46 2.0L

BMW's cooling system has long been a known weak spot, with the water pump and thermostat being two of the most common trouble areas. This remains true even in the latest B-Series engines found in 2016 and newer BMW models. This kit includes a brand-new OEM Pierburg water pump, a Bremmen thermostat (now referred to as a Heat Management Module), and one gallon of BMW's G48 coolant concentrate (enough to make two gallons of 50/50 coolant). Avoid spending thousands at the dealership or over $600 on Genuine BMW parts! These components can be replaced with high-quality OEM parts in just an afternoon using basic hand tools.
