The nonfunctional hood vents really bugged me. The 3.6 engine compartment gets very hot and needs a working hood vent. Here’s a DIY project that I did at $ 0 cost. I cut open the insulation hood cover around the vents to discover Jeep engineering had a drain hole just dumping onto the back side of hood insulation and going nowhere. I cut the three vent area’s open with a vibrating trim saw. Glued and taped insulation cover to give it a trimmed out look. To solve the future water intrusion problem into engine compartment made clear plexiglass covers for the exterior. Hope this tip helps with your overheating JL. I tow a 3,500 lbs. trailer and can’t wait to try this out this summer.
