Anyone notice it feels like a lot of heat coming off your jeep. I was standing outside mine with it running and seemed like a lot of heat comiong off of it. Cooling temp was normal 206 deg. I think it must be from the cooling fan running and blowing all that heat out. Just something I noticed.
My other V-6s stay in the 180-190 range, computers are all in and everything under the hood lasts a lot longer. If the heap has a 195F thermostat there is no reason for it to run over 200F (or for the IAT to run over 100F & that is usually in the 120s.)
I think he meant that's what heat is: lost HP. An internal combustion engine is only 30-35% efficient so there is a lot of heat given off. Sit there and idle and the system is 0% efficient which means that all of the gas burned ends up as heat, either in the engine, exhaust, or transmission.
Figure out a way to convert all that heat to motive power and you'll be a zillionaire.
