Hi all. This is my first post. I've owned a 2002 Wrangler for about a year. Please forgive me, I'm not much of a mechanic. Today I noticed this strange intermittent noise in the engine. It's not tied specifically to accelerating or idling. I was able to capture the noise briefly on video while it was idling in my driveway. At about five seconds in you can hear the whirring noise start then the other noise follows. Here is the video
Any ideas on what it could be? A belt or something? Thanks for any insight you could provide.
