Just put windshield washer fluid in the radiator resevoir. Suggestions?
If you mean the plastic jug, just unbolt it and dump it out. If you actually poured it into the radiator, you will have do drain the radiator.
Reelin is right, you don't want that in your system as it is a detergent and will cause foaming in your cooling system thus causing an engine overheat.
