To remove 99.9% of everything that gets stuck in there you need to remove the oil guard and lower the oil cooler. Just did this and wow.. Leaves and debris get layered/caked at the bottom. To remove the leaves and debris from the side auxiliary radiators you have to remove the fender liners up front then remove the torx bolt holding each of the coolers in place. Then you can place the cooler to the side and clean up. Would recommend doing it every year depending on where you live or how much you drive. (Sorry for the bad quality photos. I took screenshots of a video I posted on my Instagram.) This is 3 years of buildup.
