I have a new to me 58 Apache I am in the process of putting back together. I'm getting to the point of adding coolant and need some advice. It is my understanding that antifreeze is extremely toxic to dogs and cats yet it is sweet and attractive for them to ingest. I would like to add a non toxic pet safe coolant because my dog hangs out with me in the garage and I don't want him lapping it up if ever coolant were to leak. Has anyone else here done the same and if so what did you use and where did you get it. Thanks for any help.
