As long as it's a full flush, is it safe to say I can put any coolant I want and stick to it (just never mix at any one time)?
The maker specifies HOAT coolant and that is what I recommend you use. I believe the color is a dye added to the fluid at the manufacturer. Why try and save money on something that could cost you big bucks if you used the wrong fluid?
