No, color is only the preference of the manufacturer.
Most new coolant is tinted red or green. If you have a different color than that look into it a little further. You may have oil in you coolant causing it to be a brown color.
Motorcraft Premium Engine Coolant ( green color ) or Motorcraft Premium Gold Engine Coolant ( yellow color ) Use the color that came in your vehicle or is in it now
The Best coolant for your 350Z is the original coolant from Nissan or a coolant with the same color the you have in now in your vehicle. Some cars need a special type of fluid which you can check in your owners manual.

Yes it can. check the oil dip stick. if coolant is leaking inside the engine the oil will be "milky" in color.
should be red. GM uses Dex-cool and the factory color is red. unless it has been mixed with a different color
You need a wiring diagram for that answer. each vehicle is different.
Open your radiator cap and see what color the coolant is and replace it with the same color coolant, it doesn't matter what brand it is.
dex-cool coolant---it is orange in color.
If it's the original type of coolant it has to be Dexcool approved coolant, which is reddish in color. Most people, including myslef switch to the green color coolant when flushing the cooling system. I recommend this as Dexcool is known to "gum up" and clog engines. This usually only happens when the coolant is left in too long, or not changed when recommended. NEVER mix different color coolants, that will cause the same effect
