any body know how to get the red side panels off of a 400 so I can check the rad fluid, looks like they pull off but not sure and don't want to break them

 

Just bow out the middle of the panel out of the rear tab slots and then pop down on the front with the palm of your hand to release the panel. Wont hurt a thing. First year they came out I was a little cautious myself on the first one I touched.
