Open the drain plug under the left side of the radiator. There should be a small hole to get at it but it is difficult to reach. Make a tool like a 3/4" dowel rod with a slot cut in the end to help turn it, or just pull the lower hose. You'll have to remove the hose anyway to insert the sealant tabs (cooling system suppliment).
