Re: Engine Bay Temperature Reduction Help
I don't have an WJ, but I had a Durango and a RAM previously. The best way to reduce underhood temperatures was to remove the rubber seal along the windshield cowling. The downside is that if you run your vents, the hot underhood air is sucked into the vent opening at the windshield cowling.
