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.

For more than four decades, Bavarian Autosport has been helping BMW and MINI enthusiasts maintain, repair, and upgrade their vehicles while saving thousands of dollars in shop fees. Throughout our history it has been our mission to give every MINI or BMW owner the resources to take on nearly any repair or maintenance task themselves. With more than 100 DIY videos and free tech help available on our site, there is no job that is too big. We have a full team of advisors ready to answer your technical questions and help you find the right part for your MINI or BMW by phone or email. And if you aren't 100% satisfied with your purchase, returns are easy and hassle-free.
