Does anyone know the easiest way to change out this motor? It recently gave out on me while I was out running errands and I just haven't gotten around to fixing it. Also approx. how long should it take to do this?

There are Toyota factory service manuals stickied at the top of this forum, that are available for free downloading. Since I assume you are talking about a generation 2 Camry, I would download that manual and search for the information you need. It should be in there.
