I drained mine by pulling the lower hose on the radiator into a large aluminum foil baking pan you get at the supermarket. You can use that to put it back in the jugs from the new coolant to recycle. This stuff is toxic to pets so you don't want to let it flow into the driveway. Some parts stores will take the used coolant, others won't so you may need to check with your local waste management company as to disposal sites.I've searched and haven't found any help. Need to flush the coolant system on my GT. Engine is a SBF. What's the best. easiest way to get rid of the old and put in new anti freeze in my car?
