Since it's getting to be winter again I'm sure this will come back up for those who haven't burped their Jeeps yet.

|tab22092||Guys another great way to make sure your cooling system is operating as it should is to give the jeep a good hammer down thrashing. Opens the thermostat up and gets a lot of coolant flowing, cleans out any junk laying around in the pipes. My heat was pure fire after a good 20-30 mins of very spirited driving. Also air will take the path of least resistance example being out if the cap and into the overflow where it "burps". A 17lb rad cap also helps. My rad hose was collapsing with the stock 18lb. Letting me know the cooling system was compromised. Try it out you wont regret it!|

I have a 2007 JKU, recently bought it with 60k miles. The first time I used the heater this year, I heard this sound and my heater would blow hot air while driving but would not at idle. I finally got serious about finding out what may be causing the problem. The first place I came was this forum to see if it was a common problem. Thanks to you guys I checked the coolant level, added fluid and burped the system..........everything is fixed. Hot air immediately, consistent air in each vent and no water flowing sound behind dash!
That's what a forum is for! There's no telling how many hundreds of $ this same me, not to mention the frustrations. Thanks a lot!!!!

|jadmt||I have no problem getting to the bleed screw and on both vehicles they were tight. go underneath the breather from the right hand side (facing vehicle) I agree also if it were leaking there would be residue around the screw and it would spew coolant all the time. good luck hope you get it fixed as it is not normal that is for sure.|

It would have driven me crazy too if I continued to get the waterfall noise and even worse the no heat. It gets cold in Montana.

|tab22092||Lol seriously guys. Just burp the system. My 2005 44 thousand dollar silverado ss did it brand new. My 2012 25 thousand dollar civic si did it brand new. But funny enough my shitty Chrysler jeep didnt do it brand new lol. Its all luck of the draw. All i know is it takes 10 minutes to burp it.|

Just wanted to post up that my 2014 with 2 miles on the clock (the day I took delivery of it) did this. Furthermore, having just come from a 2012, I can tell you with 200% certainty (thanks to the cold front that just hit the North East) that this isn't some "harmless" noise. The heat is not nearly what it should be. On my 2012, if I run the heat at full red after the jeep is warmed up, the vents literally are too hot to keep your hand there. On my 2014, its very warm, but not HOT.
IMHO, Matador is doing the correct method, and I will try it when I have some time. You should NOT have to burp by adding coolant. That noise is due to the fact that there is air in the system. Remove the air, and the noise should disappear.
It never ceases to amaze me how sh!tty a company Chrysler is.

My 2013 JKRU 10A just had the 'toilet flush' water running sound behind the dash about a week ago.
Heater and everything seems to work fine, so I might wait till my next oil change to have my dealer check it out.
If they can reproduce the problem, I will show them your post just in case the tech is new to this issue.

.....my local shade-tree mechanic fixed mine with little effort, no tools, and no gadgets....and I wasn't even making a point about it. He was just insuring my system was full of coolant ready for winter:
Here's my observations:
1) warm engine, inspect overflow tank
2) open radiator cap, see no fluid
3) 'milk' the upper radiator hose to check level----there was mild gurgle & sputter into the radiator;
4) add slowly a cup or 2 of coolant, resqueeze the upper hose;
5) notice slight change of gurgle into overflow tank, with a few small bubbles;
6) repeated cup or 2, squeeze, etc....
7) he eventually had nearly 1/2 gallon added, no gurgles, no bubbles, suggested maybe a new cap if cx continued....
That was 3 weeks ago. Not one water-feature dashboard sound since.
He added $10 to the minimal bill for doing a few other little chores.
Pretty slick mod IMHO.

I used something like this. Its a small angle ratchet acre driver with a big phillips bit
Harbor Freight sells one
8 Piece Right Angle Screwdriver

I'm having the same issue (coolant waterfall) and I suspect the bleeder valve, but I'm not having success accessing it (2014 JKU). I tried getting a torx socket to it from a few angles, but no dice--not enough clearance from top to bottom. Any suggestions?
Thanks a bunch!

|2012Cosmos||I like it, it makes all my passengers have the urge to take a leak and I make them hold it.|

|Matador||So an update for others that have this issue. It turned out to be an open bleeder valve. The valve was left open on my Jeep. It would vent out any air in the lines, along with trickles of coolant once the engine warmed up, once it cooled down the system would de-pressurize and air would be sucked back in through the open valve, that would result in the sound behind the dash. My solution was to run the engine with the bleeder valve open until it warmed up and then simply closed it while the engine was running and the coolant system was pressurized. That ensured that it was properly bled and no air is sucked into the line once it cooled down. I'm happy to report that I don't have any more sounds. The coolant system is finally bled properly and the Jeep is running great again.|

|Matador||I took a look at the bleeder valve at the end of the top coolant hose. Its in a very tough space under the throttle body, so getting a screwdriver in there is tough. I ended up using a small ratchet driver and noticed that it was really opened up. I had to turn it a bit past a full rotation to get it tightened. I started up the jeep and got the same sound. Drove into work and checked under the hood. I could hear a very slight high pitch noise coming from the radiator cap. I think what I need to do is drive it again, have the engine running and loosen the bleeder valve to let out whatever air is still in the system and then close it off for good.|

I'm currently having this issue after the dealer replaced the infamous ticking head. I have brought it back a couple of times and they claim not to hear it, which is a load of BS. I'm taking it back on Sat along with this video I took. I basically pulled the glove box off and got my phone next to the coolant line inside the Jeep. I think you can make out the coolant trickling sound. It sounds like your next to a little stream

I started also started a thread, not knowing that this one existed...

|JeeperJake||Someday I'll get around to doing this process.....now with 62000 miles I've grown rather fond of the sloshing sounds.....|

|CHALLENGER2014||Everyone make it easy on your selves and have the dealer re-route the heater hoses to fill from the bottom up and replace the Sundram cap with a Stant cap. The sundram cap has a very small sealing surface and if not perfectly aligned it will allow air to be sucked into the cooling system. You can fix it for a short time by burping the system but it will come back unless you replace the cap.|

|mikebot||I tinkered with my radiator cap a few times, and topped off the radiator with Mopar's million dollar purple coolant and the sound has gone away. I have a brand new burping funnel that I never got to use if anyone wants to buy it...along with a $50 gallon of purple coolant. Haha. $80 wasted.|
