I'd really like to have a discussion with Jeep engineers or someone who knows about the topic. The underhood temps of the 3.6 are hotter than any vehicle I've owned before, but no overheating so far. Here in AZ dry rot sets in on tires in less than 5 yrs, 3 sometimes. What's happening to rubber parts under and around the hood? The engine itself? The first couple of oil changes were dino oil and the old oil didn't smell like it had burned. That was last summer. I switched to synthetic at the third oil change for a little insurance. It can't be a bad thing to vent the hood somehow, but is it really necessary? Besides, I'm always a little skeptical of advertising claims. Is there a solid reason Jeep doesn't pay more attention to it. There was a thread yesterday addressing climbing engine temps. as the 3.6 with auto tranny accumulates miles. Granted the tranny cooler sits in front of the radiator, but why doesn't it do it when new? Before I sink a bunch of money on something I think is needed, I'd like to know a little bit more.:thinking::thinking:
