Pure Old fashioned WATER!
Everything else will cause the "crud" to disappear & could cause leaks.
Now if you want it CLEAN instead...Well this should do the trick >>>>> GM P/N 12346500 Prestone Heavy Duty Cooling System Cleaner
Only draw back to this is that you'll need a thermostat & Radiator cap too if this is used. NOTE: this stuff will eat EVERYTHING if left in system for longer than 20-30 mins too. We use it at GM to clean out really rusted systems.
