What makes antifreeze turn redsome antifreeze is green and some is clear. what is the ingredient that causes it to turn red in color also can you add that ingredient to other antifreezes?
The color of the antifreeze is made that way and no dye is available. There is no reason to color it afterwards. The reason for the different colors these days is because they have made it with different properties to match specific engine manufactuerers needs. Newer engines now take pink or red for example due to blocks and cyl heads being made from different metals and they are also trying to prevent engine failures due to the way earlier coolants had on engine parts. Mixing colors isn't a good idea but that's still up for debate by many people.Go with what the owners manual states.
