So I’ve had many 4.0 Jeeps (not all Wranglers) and for the most part, they have all sounded the same. That was the case for my LJ too until this evening when I took it out for its maiden drive after completely overhauling the cooling system. It’s very bizarre and I’m not sure how to explain it other than it seems way louder during acceleration. Like the more I accelerate, the more of a “whoosh” sound I hear. I feel like I hear more whooshing than I do engine now which it definitely didn’t do last year before the overhaul. Since it gets louder as I accelerate I can only assume it’s the fan moving more air but it’s the same fan I had before, just with a new clutch...? I know this sounds weird but I know how my Jeep sounded before and how it sounds now. All gauges were where they needed to be, just FYI. Speaking of gauges, I was somewhat disappointed to see the Jeep running at 210 degrees after the complete overhaul. I thought I would at least get a few degrees from it.
