Recently I was going to add engine coolant to my daughter's recent purchased car (2001 nissan altima). As per the manual it states to add the green fluid. However, when I looked in the reserve, it was orange. I know you cant or shouldnt mix however I was wondering if I should just add the orange fluid or have it flushed and filled with the green coolant?
