I have heard of people using CLR or muratic acid in the radiator to clean the block out. Don't know anyone personally that has done this and I would imagine after using either, you would need to replace ALL hoses, water pump and thermostat again. Do not take this as my advice, just something I've heard throughout the years. Do your research before doing this.
