cooling system pressure?
Does the cooling system pressurize on Wranglers like a regular cooling system? Reason I ask, I came home last night and was checking under the hood and my upper hose wasn't hard and was somewhere between hot/warm (able to touch). Coolant levels looked normal in the tank and radiator (after it was cooler). I had just ran the Jeep about 35 highway miles, operating temps around 210, even after coming off highway. I checked within less than 5 min of turning the Jeep off. System is tight with no leaks and coolant is clean.
I am used to the hoses being near rock hard until the system cools off, but I am learning that Wranglers tend to operate a bit differently than other vehicles. I've had my Wrangler since this past Wed so some of the quirks are still new to me. Familiar to Jeeps but new to Wranglers.
