Changing engine coolant

I am about to change the coolant in my 01 power stroke and wanted to know if it is ok to use prestone antifreeze, and if I just drain the bottom of the radiator will that one plug drain everything, and how do I fill it?

Thanks for any info

Prestone in the yellow jug is not to be used. Get some Zerex G-05. It is good for 100,000 miles and no SCA is required. In addition to the radiator drain plug you need to pull the plugs on both sides of the engine block. You refill through the degas bottle on top of the radiator.

Powerstroker;
I looked at those plugs but wondered what size wrench would fit them, they're square, right? And it looks like the one in the back, on the driver's side, is a square allen wrench-type fitting (you know- a square hole not a square head). They seem to be several of them around the bottom of the engine. It looked like one would dump water all over the starter. Am I looking at the right thing?

So is the zerex still green in color, and why no additive? Also were are the block drain plugs located?
