Not only did I have to replace the radiator, but the coolant fan and the few other parts. By the time it was all said and done it was over $3,000. A few months later, the clutch went out. Come to find out that the "carfax" I received on the car prior to buying was worthless, as the car had been wrecked and the left front end had issues. It also had electronic issues with the ac/heating interior control unit also quit at the same time the radiator quit working. I will never buy another BMW.
