So I went for an oil change for my truck yesterday. This is not a very good pic, from my cheap old cell phone, but you get the idea. Squirrels had built a nest in my air filter box! I haven't been driving it a lot lately, but at least a couple of times a week!
DAMN! Even I don't run that many fluffy things over! I guess you have to change the air filter more often or look for the air leak off the wheel well throwing dust and roadkill debris into the filter.
They got into my wifes air filter and chewed it up and made a nest out of the paper a few years ago. That and they thought the EGR valve wiring was edible and ate it to.
Dad had a bird build a nest under the hood right next to the battery in his '84 way back when. It actually had a couple eggs in it. In the birds defense the truck hadn't moved in awhile but still...........
I had to install hardware cloth on the core support where air enters and on the airbox where it meets the fender. Be happy that's all they wrecked. This pic is from under the jack storage box, where the rodents took up residence in the cab.
Family had a Hummer H3 shut down few years ago. ECM couldn't move the throttle plate because chunks of the air filter and critter nest jammed it up. No screen anywhere to prevent this from air filter failure. The wiring damage alone was $1000.00. Insurance covered it under vandalism.
Something I've started to check on trucks I've let sit or something I'm looking at buying. My wife's truck was not near this bad on the air filter when we bought it last year, but had a lot of debris brought in by mice.
