I was doing service on my F150 this weekin andsaw where it was about half a quart low of antifreeze, I looked in my shop and I have almost a gallon of the orange Dextron, antifreeze that goes in my wifes car, the antifreeze in my truck is green, can I mix it, somebody told me it was not a good idea,
"Somebody" was right. The two should never be mixed. SC Tom
You can't mix them because they are different chemicals. The color is just a handy indicator to remind you. The green is Ethylene Glycol. AFAIK it isn't used much in new cars, but it used to be used a lot. (my '93 and my '90 BII and my old '91 escort all use(d) ethylene glycol) I don't remember what the orange and red coolants are, or the reasons why they are "better". I'll never be designing a cooling system so it's enough for me just to remember that there is a good reason not to mix them.

Those tow coolants will combine to form a gray sludge and gum up your cooling system. Don't do it. Texas Parts Guy

I'd drain, and backflush. Then use what the owner's manual specifies, or use G-05
