Where is the radiator drain plug on a 1999 Chevy Blazer?

The radiator drain plug on a 1999 Chevy Blazer is located at the bottom of the radiator, usually on the driver's side. However, it's not always easily visible. You might need to get down low and look carefully. It's typically a small bolt or plug, often made of plastic or metal. A shop rag or drain pan is essential to catch the coolant when you drain it.
