Just rolled 1000 miles on my new jlur. While driving today I was scolling through my menu screen. And noticed my engine temps were hovering around 220. Ambient temp was around 75. Is this normal operating temp?
Returned home and open hood to look things over.
I noticed a coolant leak at the reservoir nipple and also at the T fitting to the egr cooler. Coolant is more noticable at the T fitting. To the point of leaking down on the front diff. Checked clamps and they all seem secure.

Yeah itā€™ll go even higher temp depending on temp outside and if your going up hill. I saw coolant at 228 a few weeks ago. Pretty high but all my buddies JKā€™s 3.6ā€™s run the same...so seems normal.

And about the coolant...shouldnā€™t be coming through the clamp like that.

DO not use a radiator stopleak, it is for old cars (and for those who want a cheap temp fix) not for a brand new vehicle. Additives to stop the leak are bandaids, not real solutions.
Fix the leaky clamp or have the dealer do it under warranty
CARGUY I know you are offering advice, but Please do not give advice on the forum unless you know the technical details, as some people take wrong/inaccurate advice and act on it.

Not trying to argue, just helping. Peace!

Iā€™m having this issue now. The top T joint with the overflow line is leaking. Did you ever fix this ?

What engine? Have you read these threads?

I'll argue. It should be
NEVER use a radiator stopleak, not even in old cars unless it's an emergency.

Have you been monitoring your coolant temp? Those fitting shouldn't leak under normal circumstances and normal pressure. If your coolant is getting too hot it will increse pressure which could cause it to leak through the fittings.

Had something similar happen to me over the weekend. I went through some mud and got mud in my radiator, among other things. This caused my jeep to overheat.

At one point when I opened the hood it was steaming and there was a faint smell of engine coolant. There was wet mud on the engine so I thought most of the steam was coming from that. I did check the coolant level and it was fine at the time, with the hot engine. I had a lot of shit going on so I didn't look for coolant leaks.

Now with the engine cooled, the coolant level is clearly a little below what it should be.

You may want to keep a close eye on your coolant temps. The temp guage has a very wide range before it will start rising above the normal range. On my way home this weekend after my troubles I mentioned my coolant temp ranged from 220 to 225 and got up to 230 (ambient temp was in the low 60s) a couple times, but the temp guage never rose above the normal level.

On Sunday I spent about three hours with a garden sprayer directly on the inside of the radiator. There was a LOT of mud in there that was blocking airflow in about 25% of the radiator.
