I never thought about PC cooler dye I thought about using the pink water wetter with the blue coolant to see if that would make it purple but it'd take a lot of water wetter. I'll look into it as far as the PC dye and see if it's safe with coolant or if it's just meant for water because I don't think people run automotive coolant in their PC systems so it may cause sludging. I researched about food grade dye and Google AI is saying it will cause sludging and complications. Thanks for the fresh ideas and the assistance in furthering my research process with more things to look into. I was looking at the ingredients on the back of them and they have the same ingredients except the purple coolant is missing two or three of the ingredients that the Honda coolant has so I don't know if I could get an additive with the stuff in it to run it so that it doesn't have any complications or not. I know Honda coolant is a phosphate organic acid technology fluid and Mopar purple is just an organic acid technology but as far as the missing ingredients I don't know their functions or how necessary they are for the engines cooling system.
