Default Coolant Change?

Has anybody done a coolant change? Where exactly is the open valve? And is red the only color that should really be used? Thanks.

I believe it is bottom of radiator on drivers side. White draincock. Use Toyota red. You can get it mixed 50-50 or get full strength and mix it with distilled water. After you get about a gallon in there, cut the car on and turn heater on high and top off as necessary. Clean and refill the overflow jug too.
