Access the rad drain plug through a round cut-out in the plastic shroud on the drivers side, just behind the bumper. Use a 19mm deep socket and take it easy with it, it's plastic also. After draining, wrap a towel around the end of your garden hose with a pressure nozzle on it and insert it into the neck of the coolant purge tank and squeeze for a couple of minutes. Let drain, reinsert plug and refill. This is the half-ass method that most people use.
