I have to winterize my car for the winter and was wondering if anyone knew about the new red/orange/pink coolants. My motor is all steel except the heads. What are the benefits of the new style coolants over the old green kind, does it have any better anti-corrosion capabilities. What do you guys run that run it. I know most of my recent big trucks all have been using the red kind since about 09. Thanks for any advice. Greg
