Where is the radiator drain petcock located and how do I get to it -

The radiator drain petcock is usually located at the bottom of the radiator on the lower tank area, Only open this when the engine is cold. -
Comment 1
Is the petcock on the passenger or driver side and can you reach it from above or underneath ?? Thanks -
Comment 2
You will have to access from underneath the vehicle and it looks like a small pipe (3/8") with a cross that you turn on and off like a garden spigot. -
