I am having a time at trying to drain the radiator on a 2003 Pontiac gran prix. How is it done? I am not familiar with the drain plug (if that is what it is). I found a small white plug like device on the left side of the radiator however it has a triangular top as if for tightening only. Is this the drain plug? How do I loosen it? Please help!

Turn it counter clockwise:
Sometimes you'll need to pull on it as you turn, with pliers.
If you have to pull to get it loose, you'll need a replacement.
