The techs are all overworked and rushing to swap all these heads. I'm hoping that by the time mine does go (which at this rate will be past 50k miles of course) I will actually get a decent repair and never have to go back, instead of getting my Jeep back with oil all over the engine, loose hoses, and sloshing sounds from the cooling system, and becoming a permanent customer of the service department. At that point it's damaged goods and I don't want it anymore, much less any other American vehicle. As it stands, the Jeep is my only vehicle and I need it daily for school, work, grocery shopping, etc. Don't have time to play games with the dealership and certainly can't afford to lose my only mode of transport while it sits in their shop and they twirl their thumbs. I'd trade it in for a new one, but I have a lot of $$ in it already. My only option is to sell it or baby it for now, and I don't want to sell it

I agree with Blastek. Just drive the Jeep until a failure happens with that head. It will be handled under the 5 year/100,000 mile powertrain warranty. Call Chrysler Care and make a claim about the ticking noise. You will get a claim number. Make sure the driver's side head ticking has been mentioned and logged in the service notes.

While I was not happy with the head situation (probably same engineers who designed the web site) it is what it is. This situation will be resolved. Just try to chill and enjoy the Jeep until the head throws a CEL.

As far as your mods, did you not keep your original parts? If you're going to trade it in soon, just remove your mods and put back to stock, if possible. Then you can re-use the mods on your new one.

I went thru it all. I had my driver's side head replaced in June. As always, just my 2 cents...

I forgot to mention that once you get a claim or ticket number from Chysler Care for the ticking issue, you WILL get a loaner car to drive when the dealership replaces your driver's side head. So relax. It will work out.

Well I have about 29,000 miles on my 12' JKUR...Had the driver side head replaced around 23,000 miles. Noticed around 26,000 miles that my anti freeze was almost gone...Dealer checked for leaks, found nothing and purged and filled it. Now at about 29,000 miles on the ODO i'm out of coolant again. Couldn't find any leaks so tomorrow morning they are doing a leak down test on my new AB head. No ticking but eating anti freeze. It's not leaking but magically disappearing...They said its not the first AB head they've seen have this issue and have had to replace multiple heads 2 or 3 times due to this...They said a majority of people had no clue and the dealer notified them upon doing a fluid check during oil changes. They've even seen the issue on new Grand Cherokees and Durangos from factory eating anti freeze with the AB head.

My co-worked reported the issue months ago when a different dealer replaced his wrangler head. I thought it was just his not being put together correctly however now i'm getting more curious if its a larger issue. My dealer, who's a huge dealership said they had to get more pallets of heads ordered due to having to do some multiple times as some cause coolant leaks....This sucks....If it keeps happening I'll be buying a different vehicle.

One more quick question. Do you know the Julian number of your existing ab head? I've got an early build 2013 and am curious what I have.

I think that is the newest AC head actually. Your Julian build date, 1063, is the 106th day of 2013. That's a good 8 months after the latest upgrade to the AC head. ( which was 2062, 206th day of 2012)

Interesting and they said it was an AB Head, fools...either way I'm losing coolant like crazy and the head will likely need to be replaced or fixed, find out on tomorrow's leak down test. Such a pain. Makes me more worried that it's an AC head

Yeah, make sure, in the future, if you have any oxygen sensor problems or catalytic converter problems, that they are covered under warranty. I can't help but thinking, burning that much antifreeze can't be good for everything downstream.

A bad head gasket, a warped head, or both is my bet. The coolant is either mixing with the oil, leaking externally, getting blown out the exhaust or all of the above. A Used Oil Analysis will tell you if its going into the crankcase.

Sold all my original parts. Filmed this on 10/7 when the engine was quieter than usual...

Well after almost 2 years of carefree Jeep driving and the occasional browse of this thread my beloved JK has begun sporting a CEL

Just kidding after following this thread for all these months I knew what it was as soon as the CEL went on. Set up an appointment and guess what I will be the proud owner of a new AC version drivers side head by Thursday afternoon. The dealer was great provided me a loaner at no cost and had the new head in stock. I am glad it went under warranty and hope this is the last I have to be concerned about this issue. FYI this is a 2012 JKU delivered on 12/7/11 and I had just clicked 13,902 on the odometer. I should also note it ticked from the day I brought it home.

Thanks to all for posting in this thread it allowed me to enjoy my jeep and not really worry to much about it!!

Well got the jeep back. They did their leak down tests and found no issues. Performed the test a second time and nothing. They see no leaks and inspected the head and found no issues. The purged the coolant and refilled it. They want to look at the levels again in 4 weeks...I'll be calling Chrysler and opening a case with them on this because I know in 4 weeks ill of list coolant again

Still no "factory" AC heads? I hope it stays that way.

The warranty is a concern form.

Next week will be 1 year for me, and I just turned 5900 miles.

At the rate I drive, my 5 years will run out at the 30,000 mile mark. Most people will probably have double that.

This is just a case of sloppy work. Most likely the head gasket leaking coolant into one or more of the cylinders. The reason why I traded my 2012 in on a 2014.

Wouldn't this show on a leak down / pressure test?

All they have to do is remove the radiator cap and put a pressure tester on, they'll know if the head gasket is bad in a minute or less.

If it's real bad, yes. Sometimes, whether it's the gasket, or a crack, the leak will only manifest itself during certain instances . During the expansion/contraction process as an engine heats up/cools down the leak will occur at a specific temp, then not so much as it passes this point( either warming or cooling ) Other than the engine, this is a very commonly occurrence at the crimp seams of aluminum cored radiators /heater cores as well.

I have 12,000 miles on my '12 JK which I purchased Aug '11. No CEL yet and at the rate which I put mileage on the Jeep, I will likely only hit 25,000 miles at the end of 5 years. So if I don't throw a code by this August, I plan to purchase a full Chrysler 8 year, 70,000 mile warranty. Now that I've made this decision, I can continue performing modifications to my Jeep. I thought about trading it in for a '14 or '15, but I decided to keep it with a warranty.

Now it appears I can expect a water pump failure and of course I need to get the recalled hoses fixed. That warranty is looking better all the time.

That's what I did. I keep my vehicles a long time. I actually got the lifetime warranty. My 2012 JKU already went in for water pump failure and the recalled hoses. I love my Jeep. And I will not let the ticstar steal my joy.

Good info! Either way a good tech should be able to figure it out, after all the coolant is going somewhere. They could also take a sample of the oil send it out for analysis and in a few days know if coolant is finding its way into the oil or not.

I just did head gaskets on a Maxima for my brother in law I drained about 10 qts of oil and anti-freeze when I pulled the oil plug. That was a pretty easy diagnosis though. LOL

I had a check engine light come on in my 2013 Rubi and because of that, decided to buy the lifetime warranty from one of the online vendors for a super cheap price.

It turned out to be the Torque converter which they replaced at 8k miles but gave me a loaner car while I waited for the repair.

This thread is why I decided to purchase the warranty as we are planning on keeping the jeep until the wheels fall off and I don't want to have to deal with paying out of pocket if the head goes after the factory warranty expires.

Just dropped my 2012 JK off at Jerry Ulm Dodge here in Tampa. They say I do not get a rental car!? But that it can be swapped in two days. I don't have time to read 200 pages of this thread... but I will try to get the important info. Shouldn't they give me a rental? What info do I need to ask from them (they're being pretty dodgy)

Call Chrysler customer care - start a 'case' on your head replacement and tell them to instruct your dealer to provide a rental.

Thank you Up Hill Bill - I did threaten to call customer care, and they came back with a much better attitude and paid for the rental car! I bet it's cheaper for them to deal with their on-site enterprise than have Chrysler get pissed at them.

Thanks to this fantastic forum! My only suggestion would be to compile this info in the first post (TSB #, important phone #'s, etc.) so that all future JK owners with this issue (there will be many it sounds like) can solve this problem when they're panicking at the dealership.
