It's back

The chirping has returned with a vengeance. I took my Jeep back to the mechanic and it took about 20 minutes before the chirping started again. He got a stethoscope and after 10 minutes or so came to the conclusion that it was the right idler pulley. I did some research and this also seems to be a common cause of the dreaded chirping.
I think that when the mechanic blew off the engine with a high pressure air line he may have temporarily cleaned off the pulley ???. I tried blowing it off with air but the noise keeps coming back. I have ordered a new MOPAR pulley as I am trying to stay all MOPAR due of warranty. Here is the URL for JKOwners site that has a thread in ref to the idler pulley problem.

Bad Idler Pulley? - : Jeep Wrangler JK Forum

I searched Google using "2013 wrangler idler pulleys"

dinkydau My 2013 JKSU has chirped for 8 months since the 1st week (4300 mi ago) and I have put off visiting the dealer because I am in So. Korea and I would probably end up losing 3 or 4 days work going back and forth.
The good news is that I had my oil changed today locally for the 1st time and the chirping has stopped ?????. It was so quiet that I tried starting it while it was already running and the mechanic thought I was senile. I have no clue why it stopped but I hope it's forever and so do all the dogs in the neighborhood.

Chalk one up to another water pump failure

Just had mine done as well. Jan 2013 build date. Slight noise that was only there once the engine was good and hot (sitting at idle for 3-5 min or after driving around town then sitting in the drive thru, etc). Replaced under warranty at first dealer visit (and it made the noise for them, thank goodness). I think they used HOAT instead of OAT so I need to check with them and see if they will flush it fully and then refill with the OAT. They replaced with part number 68079412AC, so I hope that is the new and improved water pump. 8,413 miles

bravens1 My 2013 JK started chirping around the 2,500 mile mark....finally took her to dealer this morning and had the water pump replaced with 18,477 miles. Picked her back up this afternoon and no issues with dealer whatsoever.

RubiconSS I dunno. Mine is quiet as a church mouse ALL the time unless I'm driving on a country road (road not highway speed) and I hear "bird chirpping" sounds like its from behind glove box area. I just figured it was a Jeep sound. I suppose if it was a water pump I'd hear it at idle too.
I dunno.

In case you missed the update from the other thread:

Water pump (and A/C fan blower motor) replaced at 12500 miles.

I first heard the abnormal water pump noise when standing on the curb while my youngest was practicing his parallel parking skills in preparation for his driving test. My other son was with me when I first noticed, and I asked him, "You hear that?" He was perplexed, as he didn't know what he was supposed to be hearing. The noise was intermittent, noticeable at idle, and then disappeared as RPMs increased. He was surprised the dealer techs said the water pump was bad when it was taken in for work on the A/C fan blower issue...

...just goes to show that every now and then you need to have the doors off in some manner... like standing outside while someone else drives your rig, so you can hear what's going on.

Same on my 2014 JK 4Dr

Just got my 2104 JK back from the dealership, this time getting the water pump replaced. The first time I had the chirping fixed was within my first 1,000 miles. At that time they replaced the alternator and it seemed to make the chirping go away for about 20 miles. My schedule and lazy nature let the next 14k miles slip by before taking it back in. This time the dealership mechanic heard the sound and knew right away what it was.

So far so good, I think they chased away what the kids have been calling "Daddy's Canary"... fingers crossed.

spieg You can wait for the sound to get more consistent (and it will get more consistent). I havent heard of any situations where it failed catastrophically. Im on my third water pump and the second one I ran chirping for almost 20,000 miles before getting it replaced. The other thing you could try is asking them to put a stethoscope on it to listen for noise. They should be able to hear it pretty easy. For mine, the best way to generate the noise was to drive on the highway for a little while and then let the jeep idle. The last time I had mine replaced, they dealership told me that there was a new part number for the water pump that superseded the old part number. The part number they have listed on my work order for the water pump is 68079412AC. Im not sure if its really a new part number or not. Hopefully the third water pump is the charm for my jeep!

xirtic As the bearing gets worse.....the sound will be more consistent. Once this happens, the dealer will try and address the issue. They often will start with the idler pulleys.....then when that fails they will concede that the water pump has failed.
06-09-2014 05:41 PM
alecm858 Has anyone here experienced service reps at your respective dealerships refusing to replace or repair the part because they cannot hear the sound? I have brought my 2013 JK Unlimited Sahara in twice because of this and both times they say they cannot replicate or hear it. I even had a video but they refused to even watch it. What should I even do in a situation like this? I'm considering taking all my service to a different dealer for the future.

HAFICON Defiantly not a chirping noise. Sounds more like my power steering pump noise started after I had a new head installed due to the tick.

Noise 2012 JKU - YouTube

Now this was taken days before the head replacement. No whining noise.
But for sure tick.
2012 JKU at Shoe Creek - YouTube

This was taken early December on the trail you can hear the whining noise form a far, from the guys with a bad water pump did yours sound like this at any point?
Haficon 4 - YouTube

Now the easy solution would be take it to the dealer but they charge me $150 bucks just to look at it. Yes it is under warranty 28K miles but the name stealership was given for a reason.

Moha 2013 Jk with 36000Km, took to dealer yesterday to have the water pump replaced.

Sound got too loud and was very annoying.

Got mine back yesterday...sound is gone. Seemed to me they know they have an issue with the water pump. Better now as its under warranty I guess...

It was a pain because at first it didn't always make the noise, so took 4 trips to the dealer. One of the times they replaced the wrong part too, then figured it out.

I made a video of it (mostly for the sound).

Had the exact same issue on my 2012 JKUR. Dealer replaced the water pump under the warranty at about 14k miles and the issue was resolved.

Red04Cobra Mine does the squeal, and then does that chrip. No idea what either is, but sounded similar to what someone else posted earlier.

I figured he was just giving me lip service but to my surprise he just brought the original water pump into the waiting area for me to inspect. He said typically if it were an issue with casting sand left behind he would expect to see some abrasions on the impeller but wasn't seeing anything like that in this case. I guess we'll see if I'm back for another replacement in 10,000 miles or not.
At about 17,000 miles water pump number 2 is chirping. Its a bit more intermittent than the first was, so ill run it for a little while. I plan to make a pretty big stink when I go in for this replacement. I think this time ill be pretty insistent on a full system flush.

Well then I guess they better replace mine based off my video.

DallasJKU What happens if the water pump completely goes??? Am I stranded wherever that happens??
11-22-2013 01:28 AM
DallasJKU This is the video I shot with sound. Does this sound like water pump??

Well I can't figure out how to post a video.

Chad s Just had mine replaced and they didn't remove my grill.

Mine started chirping about 2200 miles - called dealer and he ordered without me even bringing it in. Back order... But now at 5300, chirp is gone, it seems to have stopped somewhere about 4,000 miles. Think I'll wait till it returns.

Question, do they have to remove grill to replace water pump? My winch is up so tight against grill, that it's a challenge getting to off. If yes, I'll take off before going to dealer for replacement.

Lusus_Naturae Put me on the list too I think. I was at work today when I had a guy come by and start talking with me. The Jeep was running and we both stopped mid conversation when it started chirping. So frustrated... I had a 2005 TJ that never had any issues and I traded it for this piece.

The dealer had known me for years at least, I hope I won't have issues. Tomorrow I guess I'll be stopping by to get it checked.

I have a list I'm working on since I use the Jeep for work and really can't go without it very long.

On the list - trans line recall, front right brake line rusting out, waterpump chirp, pass. rear tail light taking in water in the rain from the lens.

The dealer has the brake line waiting in my box already, I wrapped the trans line awhile back so not too worried there, but the other stuff hasn't been brought up yet.

ltwgs Finally found a dealership in AR that is worth my time. It helps to take the service ladies out for margaritas, by the way. Just sayin...

Only took a minute of a ride-along before the chirp came back, and they ordered the new pump immediately. Outpatient treatment when it arrived, too easy!
