 I think the only filter on that, it might have an evaporative emissions filter on it, which can be changed if it starts to become hard to fill with fuel or you get a check engine light for the filter clogged. But other than that, yeah, you're physically looking at it and cleaning, thorough cleaning of everything, especially the area between the radiator and the AC condenser. It will build up a dust that you can't really see without pulling the top cover off and looking down in there. And that can lead to overheating.
