Where is the radiator drain plug petcock on a 89 Ford Tempo?

On an 89 Ford Tempo, the radiator drain petcock is located at the bottom of the radiator, on the driver's side. It's usually a small valve or plug near the bottom radiator hose connection. You might need a wrench (usually a small one, like 7/16" or 9/16") to open it. However, some models might not have a petcock; instead, you might have to disconnect a lower radiator hose to drain the coolant. Visually inspecting your radiator is the best way to be certain.
