Mixing Green And Orange Coolant

[Ortman]

I just found out that mixing green and orange coolant is a bad idea. Now the question is, how do I get it all out of my radiator?

There should be a plug on the bottom of the radiator. Take that off and drain the liquid out. You should also flush that and the hoses out with water to clean the entire system. Other wise, the leftover mixture will keep circulating through the system.
