How does this stethoscope look from Autohauz (since I'm already getting the filters and serpentine belt and maybe the idler pulley)?

The only problem I foresee is that those parts can rip your arm off so I am not sure HOW I'm going to get a stethoscope in there w/o getting coiled up in the belts, rollers, and fan!

PS: I have a friend coming over to help me videotape the noise since I need to rev the engine and film at the same time for that debugging test.
