|lando76||I have a 13' and it to had the waterfall sound behind the dash. I opened the radiator cap squeezed the tubing a couple times and put the cap back on. It didnt immediately solve the problem. It fixed itself after about 1500 miles. It just went away on its own. I havent checked the heat yet because here in Ca winter hasn't showed up yet. Ill crank it after work and check the vent temps.|

Our 2012 just came out of dealer. Two days. Replaced heater core, t-stat and radiator due to cold air on drivers side/hot on passenger side
Seems to have fixed it

Mine has the water sound…JKUR 2014 with 400 miles Doesn't really concern me. I'll just burp the system.
Seems like it comes and goes for some…or just goes away all together.

My 2014 had the "in-dash woosh" sound. I burped it. It went away for a short while and came back.
I took it to the dealer and they fixed it. There's got to be a TSB or some other notification in their computer from the factory.
Oh yeah, there was also an issue with the cooling fans not being programmed at the factory to come on! They fixed that too.
Check yours out if you've got a 2014

My toilet went away after a couple thousand, came back, and then disappeared for about 6-7k miles more. I'm at 10.5k now and it hasn't been back. I bought a gallon of Mopar's magical purple coolant just to top off when needed. Have only used maybe a cup and a half of it over the past 6 months.
For the record, I never burped. I'm 98% certain the radiator cap wasn't sealing correctly. I cleaned it out and wiped it clean and it has been good since.

I too had this water noise (new '14 JK), and read about some people burping it with success on this forum. and I also read some people who didn't do anything, and after a while went away.
I didn't do anything. I have now about 2,000 miles and the noise is gone. Not sure exactly when it went away. but i don't hear that sloshing/flushing sound anymore. so maybe wait and see?
After reading about the horrors of dealerships mixing wrong coolants here (as it seems its really easy to confuse), which created a real problem, I just didnt want to deal with the dealer, nor buy anything I didnt need. and now, problem free. good luck

Mine seems to have the waterfall sound too.. 2014 with 300 miles on it..
Will the dealer have the vehicle burped under warranty?

Hey everyone, sorry to bump an older thread. I would like to thank all of the contributors for their valuable information concerning this subject.
I recently picked up a new 2014 (with 9 miles on it) and started noticing the trickling water noise around 230 miles. Did some research online and it brought me here. I ignored it until this weekend when I finally started to learn and get my hands dirty under the hood. It has 725 miles on it now and the suggestions here were spot on.
I rolled it up the driveway so the front was a good 3-4' above the back. Let it cool completely. Opened the radiator cap, squeezed the tube on the drivers side until the air came out/level was below visible. Filled it up using the reservoir coolant (which was about 1" overfilled) extra. Squeezed the tube again until the bubbles came/coolant level went below. Filled and repeat until I squeezed and no more bubbles surfaced. No tools or extra coolant required. The noise went down significantly. It's still present so I'll probably repeat this next weekend which should likely be the last time.

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.|
|11-13-2013 07:05 PM|
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.
