Hey guys, Where can I find a complete cooling system for my 91 m5. BMW put in a plastic impeller when it was made, rather than a heat resisting metal impeller. The radiator is f-ed and I am going to have to replace the entire thing, h20 pump, hoses, radiator. I had the engine checked and it is fine, so Im pretty relieved about that. Any Idea how much and wether or not I can get them from anywhere else besides a dealer? Colorado has only 3 dealers and they all jack you! I want to get my baby back in action. Any help is appreciated. Thanks Ed M5-best car ever concieved
