yes lower drivers side on the back side of the radiator, its a white plastic bolt looking thing. then there is also a plug in the engine block, takes a big allen wrench its on the bottom near the oil pan on the drivers side about 3/4 the way back. drain it then if you really want it cleaned out fill with water and repeat the steps after running the engine for about a minute, dont run the engine without water or with the drains open
