Working on my fuel leak issue (solved BTW) my flashlight slipped from my hand and slid along the valve cover, hit the fan and dropped into the bottom of the fan shroud. It's laying there out of the way of anything, no danger of fan contact..Drove it 250 miles like this. I am concerned that someday the vibes of the 5.9 will cause damage to the rad. I can't reach it by hand, it's not ferrous metal and the shroud is about 14 ga metal so cutting a window isn't an easy option and there's not much room.
I have a few ideas but more couldn't hurt.
May have to pull the CAC and tip the rad. forward.
