Understanding how the cooling system works and where it commonly fails can prevent a relatively small repair from turning into a full BMW engine replacement . Why BMW Engines Are Sensitive to Overheating Modern BMW petrol and BMW diesel engine platforms are designed to run efficiently at higher operating temperatures.
