Don't mix orange (dexcool) and green (reg coolant)- they will reduce the effectiveness of the additives in each other. If you want to switch to green, completely flush the entire system first. Otherwise stay with dexcool.

Just in general your paying the same $$$ for pre diluted fluid, what a rip, add coolant, add water, save the other half for another time. Also like the others said, dont mix
