I recently noticed that my Toyota vehicle requires pink-colored antifreeze. I’m curious about the specifics of Toyota pink antifreeze—what makes it different from other types, and why is it recommended for Toyota vehicles? Can anyone provide insights or advice on using Toyota pink antifreeze?
Red is required by the handbook. I included pink as I had some on hand for my Tacoma.
Beyond the obvious (premix/dilute, etc.) they differ chemically, but not enough to damage components, as far as I can tell adding orange or green could be hazardous to sections of the system.
In addition, I had trouble finding red, but I could readily identify pink.
