Where is the coolant drain plug on a 2000 Buick Park Avenue?
There may not be a plug. It is best to remove the lower hose for this procedure anyway.. If you are going to flush your radiator, you should do the whole cooling system. there are some great vids on youtube for this procedure. Scottykilmer.com has one, and there are others. follow the directions and you should have no probs, good luck.
