Where is the radiator plug on a 1988 Cadillac Brougham?

The radiator drain plug on a 1988 Cadillac Brougham is located at the bottom of the radiator, typically on the driver's side. However, it's *not* always easily visible. You might need to get down low and possibly use a flashlight to locate it. It's usually a small, threaded plug. Be prepared for some coolant to spill, so have a drain pan ready.
