You should do it while the engine is hot so the oil drains faster. Removing the the fill cap should be done before removing the drain plug. That will also help the oil drain faster and more completely. And 5 quarts is too much for that engine. It's more like 4.4 or 4.5 quarts. Over filling it is really bad. The counterweights on the crankshaft will splash in the oil creating a froth with air bubbles in it causing the oil to not lubricate the engine well which will wear out the engine faster
