I was checking my fluids this morning and I noticed what looked like a light that's attached to the underside of the hood. I've seen it a million times but never actually gave it much thought - is that what it actually is? How do you turn it on?
Second - I was looking around the valve cover (I'm thinking of replacing it and wanted to scope it out a little further) and I noticed a threaded rod that's coming up from the engine (sticking straight up) with no bolt on it....should that have a bolt on it?
If you're standing in front of your jeep, it's right next to the valve cover on the driver's side of the valve cover about halfway down it.
