At least some of those are left hand thread, you turn some to the left as if opening a valve. I don't know about some/all/ many/ all NONE!!? on OEM Mopars LOL
Pretty sure they are, looking at the drain plug, turn left to drain, turn right to close. The petcock will go inwards when you want to drain the radiator. (turn it left, like loosening a bolt) The threads are left handed.
