What color coolant do you need for a 1994 Z28 Camaro?

I'm sorry , but this really is a joke right ? Well if it's not. The color makes no difference. Don't put straight antifreeze in it. It's sold premixed 50/50 or you can mix it yourself. In the winter you want it to be about 70/30 ( more antifreeze than water ) or if it's already got 50/50 in it, top it off with straight antifreeze. May have to drain some out to do this. They make testers to check it, there at the parts store and most gas stations.
