JL seems to run really hot

[Mark's first Jeep]

2019 Wrangler JL unlimited this is my first Jeep
Ok the JL seems to run really hot I mean putting your hand on the hood after a few miles it is really uncomfortable. The gauge says over 200 degrees. I have 8700 miles on this JL. The JL has always seemed to warmup in less than a 1/2 mile which seems awfully quick. Does the JL community have the same results? Dealer says everything is ok just wanted to see if this really is normal. Not sure if there is a solution to move more air into the engine compartment or not. I was wondering if anyone had tried to open the wheel wells would help? This amount of heat doesn't seem right for a new vehicle.
thanks
Mark

My 2020 JLUR (3.6l) was running around 200 ° F when the outside temp was around 70 ° F.

Mine hits 230 on hills routinely.

200 is nothing.

All my cars w/ Aluminum motors seem much hotter in the engine bay than those that I've had w/ cast iron blocks. And all coolant temps were in the proper operating range.

Ive been 4 wheeling all through and around Death Valley for the whole summer with the A/C blasting, youve got nothing to worry about. Your thermostat doesn't even open until 200 degrees. The hood gets hot because it is thin aluminum.

200 is well within the normal range. 230 is probably as high as you should see, but should be fine, especially if only doing it under load. The highest I've seen is 224, but 230 wouldn't shock me. The cooling system has high capacity, though, and can manage it. There is an oil cooler involved, too, and it is very effective with 0w20 oil.

Ok thanks for the input I don't really trust the dealers seems like they really don't know the new wranglers and what to expect is normal.

Holy crap that's ugly!

Better idea; get a rubi hood, then remove the heat blanket or whatever it is, then take out the vents and trim the bottom out, thus making them functional

I'm surprised an aftermarket company hasn't come up with replacement vents for the stock Rubi hood. That one seems like a no-brainer.

There is no issue, it is operating as designed. This is why most cars don't have an actual temperature gauge readout.

Poison has some replacement vents for the Rubi hood that are functional.
