Wow, they may have filled your 2013 with 5yr/100k HOAT instead of 10yr/150k OAT that is specified. If it ever gets topped up with OAT (as the specs call for) it'll mess things up.

Here is a cut and paste:

NOTE: If OAT (MOPAR P/N 68163848AA Purple) has been Mixed with HOAT (MOPAR P/N 68048953AB Pink Or Factory Fill HOAT Orange (Fig. 2) or (Fig. 3)) or any other coolants have been mixed, it will be necessary to flush the cooling system.

Maybe they got 100% of the old coolant out, but you will have to make certain no OAT is added to it in the future, even though that is what the book calls for.

In short, it appears they put improper coolant in your Jeep. Unfortunately, it probably needs to go back for another flush and fill.
That's what it sounds like.

Through the dealer's incompetence, looks like you got HOAT. I am not sure if I would have them re-flush and fill with OAT at this point, risking more mixing, but would notify both Chrysler and the dealer that that re-filled it with the incorrect coolant. Get them to acknowledge the mistake and get assurance that any problems that may crop up in the future will be covered. My local Jeep dealer is the LAST place I would go to get anything fixed.

The question of the moment, is whether the coolant substitution was intentional or not. From what I gather, the OAT coolant was the culprit as far as the sediment, and I wonder if the HOAT was substituted instead since this stuff isn't causing these issues. Iím guessing this is the case and have yet to hear confirmation, assuming I ever will. I am a bit less than impressed with the service manager there, the guy is probably in his early to mid-30s and isnít very forthcoming with information (plus blew me off the first time on the sediment issue).

I donít really give a ratís ass what they used for coolant (I would have been fine with the good old poisonous green stuff that always works), as long as: A) the flush was thorough enough that the new coolant and any residual old coolant isnít there in sufficient quantity to mix and B) there will be no more crud in the system. But there is that danger of something wrong getting put in down the road, despite the fact that I do all my own maintenance.

Assuming I left things as is, I wonder now if everything will be fine and there will never be another problem with the vehicle or the fun has really yet to begin, and Iím looking at a long series of service visitsÖ

Or I just dump this thing and be done with it, and Chrysler.

I agree! You are probably better off with HOAT. They used it for many years without problems.

The saga continues!

I got a message a bit ago from the service manager this afternoon and yes, you guessed it -- they put in the wrong coolant by mistake! Since the sample in my jar was a little on the pinkish side, the tech mistook it for the HOAT coolant and used it. Fair enough on the color mix-up, never mind the fact that the Jeep is a 2013.

Unreal.

Now they want me to bring it back in AGAIN to be reflushed and refilled with the OAT. I think I better settle down before I call him back....

Incompetence is the rule of thumb at the dealers. I guess another flush will help get more sludge out but I think you are OK as-is.

Yeah, wondering if the sludge will return going back to the OAT since it happened before. Why would it not???

Is there a concern they can't fully or don't fully flush the HOAT out before filling with OAT? This sounds like a huge mess this dealer has gotten himself in and I think I would at least get it on file with Chrysler should this thing go bad down the road.

Hey Stroker... at this point I would call Chrysler directly and file a complaint against this dealer. Then I would contact the dealer General Manager and bust that service manager and his incompetent service tech - both should be terminated. The service manager should be kissing your ass right about now. Your Repair Order is proof they used the wrong stuff. He should have baby-sat this situation and made sure they used the right coolant given the seriousness of the situation - if he doesn't communicate with you, he doesn't communicate to his employees and therefore he's a lousy manager.

I would demand from the GM that the dealer pays for a Chrysler MAX Life-Time Warranty.

No point in you taking a financial hit for their mistake and incompetence.

Basically my thoughts exactly. I plan on contacting Chrysler later today.

I actually lost sleep over this last night, something that shouldn't happen with a new vehicle. My confidence in the long-term reliability of this vehicle is now shaken, to say the least.

If the coolant is swapped, will the sediment issue come back? Will the HOAT coolant be completely and successfully flushed, or will I have related problems later with potential traces of it mixed with the OAT? Will my Jeep be stripped bare to replace all heat exchangers and have a multitude of squeaks and rattles down the road? The mind reels.

Getting rid of it is looking pretty damn good at the moment. A shame, since I really like it otherwise.

You might want to run it awhile and see if any sediment shows up. You have the receipt which clearly demonstrates the screw up. I FINALLY found a competent dealer service center, although 45 miles away. You should dump this dealer, but not after filing the complaint. I would be concerned with this place doing a sloppy 2nd flush and adding OAT to some remaining re-filled HOAT and making the problem worse.

This right here is what I've been harping on for some time now - both on here and with my dealer.

Identifying dye that changes color over time to a color that is not used for any other identifier is no problem.

Identifying dye that changes color over time to be similar enough to an incompatible fluid to cause misidentification is a huge problem and a fundamental engineering flaw.

I used this analogy elsewhere - if your oil changed effective viscosity from 5w20 to 40w80 in 800 miles, nobody would dispute that as a flaw in the oil.

^^^ Very true.

However, due diligence would have had the tech looking up the proper chemicals to be used on a given model year. Especially when there are two coolants to consider that don't mix.

You have a point, and what sucks is I'm willing to bet the guy topping off fluids before delivering a customer their new Wrangler could very easily mix up the two fluids. The customer has no way of knowing until there's a problem. A few things come to mind, no point in me repeating them.

Well, add me to the list of having discolored coolant and slime/sediment in the overflow bottle. 9,500 miles on my 2013.

Will talk to the dealer at next oil change.

With all the incidents of this problem, one can only conclude that Chrysler must have mixed orange HOAT with OAT at the factory and then dyed it purple. Odds would back up that conclusion.

Knuckles, I am sorry to hear you are joining this exclusive club.....

A co-worker has a '13 Chrysler minivan, with just under 10K miles. After hearing my tale with my Wrangler, he decided to check the status of his coolant. I think you can guess what he found. He's less than thrilled.

Mine goes in first thing Monday morning for another flush to get the correct coolant back in it. I've notified Jeep about my plight and have yet to hear back, and am pushing for a warranty extension to the Max 7/100K, but honestly I'm really thinking about getting rid of my Jeep now while it's worth the most. If the sediment happened once, why would it not happen again? I''m not interested in annual coolant flushes (ironic, when it's a 10-year coolant) or the prospect of ending up having the thing stripped to the firewall to replace all heat exchangers if they plug up, and then dealing with a squeaky rattletrap.

Frustrating to say the least, because I absolutely love my Jeep otherwise. But I refuse to put up with reliability issues with it being my primary daily driver. Sad, really.

I ordered in early February, and took delivery in mid-March, 2013.

July 2012 for 2013 (built right at the start of model year production so I've wondered about "leftover 2012 coolant"). Sludge and discolor to pink but clear (not muddy).

Mine was built in March 2013. I haven't checked for sludge, however this dealer appears incompetent. Are you sure at some point they didn't top off the coolant tank with HOAT? During dealer prep? The coolant tank appears low when it's not. I could see a lot monkey doing this and using the wrong stuff.

You CAN NOT mix HOAT with OAT.. period. From what I've read, this results in sludge developing in the coolant system.

I would highly doubt this was done at the factory and someone dyed the coolant purple - that's ridiculous.

Guess you haven't worked in an assembly plant. I have for many many years, and can tell you that stuff like this happens. I am sure they have a huge holding tank which get bulk loaded and the coolant/water mix is piped to the assembly lines. One dumb material handler could be the answer.

No idea, but it wouldn't surprise me.

I remember looking into the coolant tank right after I got it though, and the coolant was as purple as could be.

Xena... I wouldn't assume that. I've worked in the Life Sciences and Diagnostics industry for 38 years - instruments assembly and chemistry reagent plants. Consumables, reagents and calibrators that are manufactured in bulk then filled into small vials, cartridges, and containers of all sizes a shapes. Basically a chemical company.

This is an engineering design change and all existing materials (55 gallon drums) would have been quarantined and returned to vendor or sent to a plant still using HOAT. The entire plant shuts down for a change like this. That's why it started in the beginning of a model year.

They would have had to flush and decontaminate the entire system.

Let's say it did happen. Where would the employee get the dye? Run out on his/her lunch break to the grocery store and buy it? Pour it in the tank, mix it somehow and test to see if they got the color right? I don't buy that scenario.

More than likely this is happening in the field where they are mixing two different materials that have been packaged and labeled with similar labels - that's a disaster waiting to happen. There is no way to prevent mixing these two different, but similar chemicals and detecting it after its been poured into the coolant tank - you can't even see the full mark without a flashlight. I believe the service techs and oil change monkeys are using the wrong antifreeze and its getting mixed there.

This could also happen at Jiffy Lube, Pep Boys or some other quick oil and lube stations you see scattered across the country. You think they installed extra pipes and equipment to handle the HOAT > OAT changeover? No way...

This is happening in the field... you can even mix up the blue and black caps on the container. I said this before, the packaging engineer at Chrysler should be shot for this.

My only point here is that Chrysler would not have issued a "star" case if a few dealers were adding the wrong coolant. In addition, when someone showed up at the dealer with this problem, the first assumption would be that the owner caused the problem. I was not questioning your experience, but I see this kind of stuff every day. Material handler's don't read labels and when something is supposed to be isolated and returned to the vendor, many times a drum gets discovered later and inadvertently used. I could see the confusion here, because both the original OAT and HOAT were orange. We have learned that Chrysler then dyed the orange OAT purple to avoid a mix-up. Why would they dye it if they were returning it to the vendor?

There is also the possibility that the color change could be attributed to deterioration of the dye, or some other reaction other than mixing coolants. As I noted in my earlier post (#17), nothing has been added to my system expect distilled water (I do may own maintenance). The coolant was a distinct purple when new (both in the radiator and recovery tank) and it is now orange/pink. Fortunately, haven't seen any noticeable sludge yet in the radiator or recovery tank. Heater works great.

I have the same color change but with no sludge. The folks posting here who have the sludge problem most likely got the wrong mix somewhere.
