The E39 5 Series and the E38 7 Series used a cooling system made almost entirely out of plastic. Over time, age and thousands of heat-cycles cause the plastic components to become brittle, crack and split — creating leaks that could put your engine at risk of overheating. The radiator is no exception. Made by an OEM supplier to BMW, NRF, this is the same quality as the radiator installed in your car at the factory all those years ago, and is sure to provide years of worry-free service. 

Please be aware that due to the fragility of radiators, there is often minor fin damage that occurs during the manufacturing process. In most cases bent fins are unavoidable and will not affect the performance of the radiator. If you have any concerns with your replacement radiator, we encourage you to get in contact with us.
