Another thought would be to build a frame that the router can follow along the inside. You could clamp this to the top to use as a jig.
I would start with a piece of plywood. Mark out the size of the slots that you want to make. Measure from the edge of the bit to the edge of the router base. Add this dimension to each side of the slot and mark a new box. Attach 1/2 or 3/4 inch material lined up and outside the larger box. Use the plunge router to route out the slot in the jig. Line the jig up on the radiator cover top and clamp and go to town.
If you can't use the router outside, have someone hold a vacuum hose near the router to suck up as much dust as possible. A shop vac would be ideal, but you could use any vacuum. I'd use a new bag so as to have as much suction as possible.
