Running straight coolant is not a good idea unless you're buying a coolant which is a 50/50 mix. It can actually cause an overheating problem. Some of them also need water added to protect against freezing, contrary to what you might think. I'm not sure about mixing green and pink coolant either. I'll pass on commenting about that since I'm not sure if they were intended to be mixed. As far as the change interval, check the OM and or the maker of the coolant.
