under hood seems really hot

I have noticed the past week that the hood and front of my jeep are extremely hot after my 20 min commute to work. My thermostate shows the normal 210, has never read higher even at idle in traffic. Is this a normal thing, i guess i never really paid any attention to how hot the hood gets, but it is a bit concerning.

Yep they get way sometimes. It's supposed to run that temp they say. I didn't care for it so I put a 180 degree thermostat in mine and it's quite a bit cooler. But then alot of people say it's bad to run cooler or that it's impossible and such.... But I have had zero issues with mine running around 195 all the time.

What you're noticing under the hood is perfectly normal, don't worry about it so long as your temp gauge is showing the 210 degrees the engine was designed to run at. Resist the temptation to install a lower temperature thermostat like a 165 or 180 degree model. The engine and computer is happiest with the 195 degree thermostat the engineers designed it to run with. In hot conditions, the engine won't run any cooler with a 165 or 180 degree thermostat anyway, thermostats are only there to help the engine warm up faster and set its minimum operating temperature on cold days.

relief

Thanks guys I was hoping it wasnt anything serious or something that would ruin the engine. I think I will stick with the stock t-stat since that is what the engine came with and what the engineers specified for the engine.

I just got a 2003 sport with l6 engine. The same thing. Only in my case after a half hour ride I opened the hood. It was real hot trying to push the latch and the prop rod to keep the hood open was to hot to touch. Fortunately the rod has a isalated rubber place to grab it. Is this really normal?

Pretty much, BTW how did you even find this thread? It's been dead since 2010.

I asked this question on Google and this came up. I joined the Forum a few weeks ago so I was able to post a quick reply. Everthing I heard so far agrees with what you say here. Jeeps run hot. I guess with no insulation under the hood and the prop rod just about sitting on the radiator you would expect it to be pretty hot.
Thanks for your reply, hope to talk to you again sometime.

It's designed into the Jeep, in case you want a hot meal while out wheeling.

Good, I like eggs over easy in the morning but hate building the camp fire.

About the only thing that will relieve some of the underhood heat is a vent, or louver.

Venting the hood will allow handling of the hood latch and prop-up rod without burning your fingers. More importantly, it will help a number of things under the hood: the battery, computer, alternator, hoses, wires, and everything thing else that tends to be negatively affected by excess heat. It can also help prevent heat-soaking of the injectors, which can cause operational difficulties for the Jeep.

The key is to vent in such a way that pouring rain water does not go through your vents, and soak crucial engine, or electrical items.
