There’s no buzzkill like a Jeep that overheats when you’re out on the trail, soaking in the beauty of nature and trying to mount the next obstacle. Or when you’re on the afternoon commute in traffic, for that matter. There is simply no good time for overheating. And for 99 percent of the Jeeps on the road, there’s no reason for it either. If you approach your cooling system with the same systematic approach as you do selecting gear ratios and tire size, it’s pretty easy to keep your engine cool.
