The radiator on a 98 Buick Century is flushed by turning the petcock to drain the coolant. Water is then flushed through the system until all contaminants are removed.
Everything takes a different form of Freon. Drain the system if it has not been so prior then add R134a Freon into the coolant system.
There are several drain plugs on that vehicle, radiator (coolant), block (coolant), engine oil, trans oil, etc. There are usually located at the lowest point of that particular system.
You can find the 1991 Buick Skylark radiator drain plug on the bottom of the radiator. The radiator drain plug will be in the center of the radiator bottom.
