I noticed an oily spot on that plastic skid plate under the radiator on the drivers side. I removed the plate and cleaned it, but couldn't find any oil residue on the engine or any coolant leak/residue from the radiator. After re-installing everything and checking from the top I did see what looks like oil coming from the passenger side radiator fan. Tried as best I could to get a photo/video.
Any idea if these fan motors are filled with oil for lubrication? Could it just be oil spill residue from last oil change?
