Engine Cooling problem
2005 Chevy Impala 6 cyl Front Wheel Drive Automatic

I attempted to have my radiator flushed and nothing would come out of the drain plug. What can I do to fix this?

What you could do is, put a cooling system pressure tester on the radiator, open the drain, then pressurize the system, the pressure should clear the drain, after it clears the drain, pour a pot of boiling water into the radiator slowly that should melt away the clog.
