How long will it take to replace an alternator in a 2003 Mercedes SL500. The replacement is OEM Bosch equipment/ Is it necessary to remove the radiator? The voltage in the battery shows 12.5 volts when the car is not running. When I test the battery with the car running there is no change in the voltage so I am assuming that the alternator needs to be replaced. Thanks. Ted
