Has anyone else noticed a regular click noise at idle every 15-20 seconds? I was in a drive through lane with my window open and the performance exhaust turned off (a combination of things that has never happened before) and I heard a regular metallic click noise (just one) every 15-20 seconds like clockwork for about 6 minutes straight. No other issues. Is this a "Hemi" thing? Any ideas if this is normal or not?
 
the Hemi tic, tick tick, every 15 seconds? feel special they normally do it every 2 seconds.

The Hemi tick is normal, ignore it. I read a reason why it does it but can't remember.
 
Can it also be the A/C clutch? That clicks when it engages and when the freon is low, the clutch engages frequently...at about 15 second intervals. Look at the A/C pump and see if the clutch engages when you hear the click. Otherwise, it may just be the Hemi tick as stated before.

I hope it's not low. I only have 600 miles on it. I'll check though. My Jeep has the Hemi tick at start up but it quickly goes away. This is just one click every 15-20 seconds. A few people saying this is pretty normal. Thanks
 
Bummer, NO tick on mine! That would drive me nuts!
 
I think I hear the click about every 15 seconds as well. It is the A/C clutch engaging/disengaging in my case. When you go through a drive thru again turn your A/C off and listen for the click to see if it goes away.

Thanks I'll try that this week. If it does go away does that mean there is an issue with the A/C system?

Most likely not. It seems the A/C in the 392 cycles often. It would be good to check the system to make sure it is full, however. I'll ask my dealer in my next service.

Mine does the same exact thing. 300 miles. I suspect it is a normal characteristic. Have you found out anything more
 
I was having such a nice day until I read this forum. Now I’m compelled to search for noises that haven’t been apparent to me after 1200 miles in my 392. I’m going to try the "drive-thru-with-the-window-open" test next. My 2019 Challenger Scat Pack 392 had no tick; I loved that engine so much I didn’t hesitate to trade her in for the Jeep. I had a 2014 Ram 1500 V8 that developed the “Hemi Tick" right about 30,000 miles; you could really hear it standing outside, maybe 4 ticks per second coming from the passenger side manifold. Had it replaced; ticking stopped.
 
a/c clutch, sorry last time I posted tyou weren't as specific, 100%. I have had hems for the last 15 yrs and every one same noise

Verified! I turned the A/C off and it immediately the click went away. Next issue...uhhh...what does that mean??

I have a 2003 Wrangler with the 4.0 inline six (tractor) engine. The noises that engine makes, only dissappear when I crank the volume of my stereo all the way up. Lol
