Default SC300 Coolant Drain ****

I'm currently trying to flush and replace the coolant in my sc300, but I can't seem to find the drain **** for it. I took off the front undercover already and mistakenly thought that one of the bolts was the drain ****, but I think I it's the refrigerant cause a fine cold mist came out when I unscrewed it so I think I've lost some refrigerant.

But my main question is where is the drain **** on our SC3s? The Lexus FSM lists it as being like right there, but I don't see it when I take off the front under cover. Any help would be greatly appreciated as my SC3 needs the coolant changed real bad.

When looking into the engine bay from the nose of the car (driver's side to your right), find the radiator cap (simple enough). From there, look straight down toward the base of the radiator. There is no need to remove any covers. It is a plastic butterfly nut, mine is black so it might be hard to find at first.

Also replace the little O-ring on the radiator drain ****. Heat cycling makes these hard after a spell so while it is drained, replace it. I didn't have that done and had to go back and get this fixed when the coolant was replaced.
