Use a real serpent in place of the serpentine belt.
I left an old car of mine untouched for about 4 months. Some type of rodent made a nest in the AC blower motor cavity using fiberglass from the hood liner. Left the wiring and hoses intact. Good thing the critters didn't gnaw through the blower vanes to get into the cabin ducting. I sold the car reeking of Lysol and Ozium a week after finding the nest. Felt like I was living a Seinfeld episode
