I want to do a basic drain and fill on my truck.
The coolant in it is Ford yellow GO-5.
According to Peak, their Global AMAM antifreeze is okay to use in Fords with the coolant spec WSS-M97B51-A1 (yellow GO-5). BUT, they say it "features a patented non 2-EH formula that is phosphate-free and silicate-free."

According to Ford, their vehicles that call for GO-5 need silicates.

What should I do here? Go on a wild goose chase for correct GO-5, or just use the Peak Global AMAM?
