Confusion continues over coolant colors for cars. Of course, there is still the good old green stuff, but there is also orange, yellow (gold and amber), red, pink, blue and, if you mix the wrong things together, brown. Despite the rainbow of colors, all antifreeze starts out colorless.
If you've collected at least 90 percent of the cooling system capacity, and the coolant now is clear, you're ready. If it still has some antifreeze dye color, slowly fill the system with plain water, with all air bleeds open. Dispose of the coolant in an environmentally responsible manner, please.
