My passengers dress got sucked into the engine area, what should I do…

I guess this part is like a cooling unit or ventilation unit for the engine as it had spinning flaps inside and I guess the triangular structure in the front is for preventing stuff from getting in. Sadly her dress got in and the overall sound quickly changed while driving so I stopped immediately. The cover is missing its top piece and inside are most of the flaps broken and one is stuck. It’s still spinnable but with quite high resistance due to the stuck piece. I guess I have to replace it, already found the equivalent inside parts for few euros online, but I don’t know how or what else could be damaged. I can still start the engine with the button but I don’t want to as it sounds weird. Anyone got a clue how to find a user manual or drawing so I can find the way to fix it and find the needed parts? Thanks in advance!
