With the engine covers off inside the bedroom while using a flashlight, I still could not get a good view of the radiator so I got out my small point and shoot camera and stuck it down there at all sorts of agles and into places I couldn't see. It came up with a lot of pictures to show me what I had. Mine is pretty clean except for the very lower right corner that I need to work on a little bit.
While you're in there, take pictures of all the belts so that you know how to route new ones when one breaks on you. And yes I'm assuming that you're carrying spare belts and filters - right?
