Cooling System

Your engine is cooled by a mix of ethylene glycol and water circulated through a radiator by the water pump. Proper maintenance of your MINI or BMW cooling system ensures not only a healthy and well-running engine, but also a comfortable cabin for you and your passengers. In this category you'll find thermostats, water pumps, radiator hoses, radiators, complete BMW and MINI cooling system rebuild kits, and expansion tanks.
