2013 sand/ sludge in coolant, heat works fine but near end of warrany

kind of nervous about this, 2013 JK sport. After reading about other peoples experiences with sand in coolant from casting sand or improper engine coolant or whatever. I checked mine by putting a flashlight to the bottom. It is very clearly a dark solid part about 2 inches near the bottom.

But the heat works just fine. My factory warranty is up very soon. I am nervous that if I take it to the dealership that they will say its fine and then I will get stuck with the bill to replace the parts when the heat does go. Any help or thoughts on this?

Should I take it in anyway or call chrysler? no idea what to do

How is your warranty up very soon with a 2013? And take it to the dealer and have them flush it out. Or do it yourself and top off with OAT coolant. Had to have my heater core and radiator replaced because doppie dealer mixed the wrong coolant. On second thought yea flush it yourself lol

I drive it a ton. take it on trips all the time and even took it from NC to colorado/utah last summer.

When I say im almost out of warranty I mean Ill be out in the next couple weeks. Im just concerned that they flush and a month later the issue isnt fixed and im stuck with a bill for this.

part of my concern is that from reading threads flushes wont fix the problem and you end up having to replace the heater core, radiator, and water pump.

Find some sort of long rod or something with a hook on the end (modify a coat hanger?). Then, stick it all the way down into the reservoir and scrape it across the bottom and see what comes up. We did ours that way and I found a minuscule amount of sludge on the tip.

I took it in the next day and watched while the service tech checked it the same way. He said the small amount wasn't anything to be concerned about. However, he did remove the reservoir, cleaned it out and refilled it with new coolant (it was right on the MIN mark anyway). They're going to check it again at the next oil change.

Anyhow, if it is still under warranty they should not change you anything for checking if you found something prior to that and expressed your concern to them.

The power train in the 2013 has a 5 year, or 100,000 warranty, (which ever comes first), so you should have plenty of warranty remaining!

This casting sand, cylinder head failure, water pump squeal, is only on a very small per percentage of the 3.6 engines. These engines are running in many other vehicles besides the Wrangler, with only a small percentage of failures! If you see sand it your coolant, then take it into your Dealer!

Yes some have it, but by far the majority do not. I have a 2013, and don't have the issues with mine. Am my going to loose any sleep or hair worrying about it, no way. Actually I don't have much hair to loose...

Just think about it, if it does happen, then warranty will take care of it! This is warranty money that you have already paid for, which is calculated into the cost of a vehicle when you purchase it new, so it's there if you need it.

So go get a Budweiser, set back relax, and enjoy your ride..........

^^^Then you may have a extended warranty.

My 2013 has 3 years, or 36,000 miles, whichever comes first on the basic Wrangler.
5 years, or 100,000 miles, whichever comes first on the power train.
This is the warranty, direct from Chrysler/Jeep on my 2013. I do not have any extended warranties.......

I just now seen your edit!

There hasn't been a change in warranty coverage. The question is whether the cooling system, including heater core is considered part of the powertrain warranty (and 5 yr/100k) or the basic limited portion of warranty (3yr/36k).

You can download the warranty by year and model here: Basic Limited & Powertrain Limited Warranty Coverage | Jeep

The warranty mentions water pump under powertrain, but not radiator or any other cooling system component, so I would assume the warranty on that portion ends at 3yr/36k.

What I'd suggest NH1NH1 do is visit his service department, explain exactly what your issue and concern is, and, given the sludge, ask them to perform a coolant flush under warranty due to the known problems with casting sand. If not, ask them to give you a discount on the coolant so you can proactively do it yourself.

If you're concerned and have some evidence of sludge, and the dealer won't cover it under warranty, I'd rather spend $100 or so on coolant and flush it myself than to roll the dice on a more significant (and costly) failure.

^^^Yes, the Radiator and heater core are probably covered by the basic warranty against defects.
The OP, is asking about the sand from the casting, and that would be originating either from the cylinder block, and or head. So if it contaminates the Radiator, and or heater core, then that is just progressive damage caused by the source (block/head). So that would be 5 years, or 100,000 miles, whichever comes first, because it originated from the engine, (power train).

I would take it in before 36k and tell them really concerned and tell service advisor what you think is wrong with heater core. Just because it still blows heat doesn't mean not already partially clogged. I took mine in Monday morning for heat problem and service advisor looked at me like I was crazy when told him about sludge, but a couple hours later called and said replacing core, radiator and oil cooler. The techs know what they are doing and get paid for doing the work, it will get resolved more than likely. If not, raise hell until it does.

Dropped it off this morning at the dealership. Told them I noticed about an inch of sand/sludge at the bottom the coolant reservoir and that I was worried it would clog the heater core or cause other problems. Service advisor asked if I wanted to pay for flush and that wasnt covered under the warranty. I explained that there shouldnt be sand in the coolant and that I was not interested in paying for a flush. I wanted a mechanic to look at it. I'll give updates later...

If the dealership doesnt want to attempt to fix I'll definitely call Chrysler to document the issue while I'm still under the 36k warranty.

I doubt that the dealer would cover something out of the drivetrain under the drivetrain warranty, even in this case, without some resistance.

I definitely get what you're saying and it makes common sense, but depending on the dealer, most shops look for the the first opportunity to avoid warranty work vs. performing it. I learn more and more that common sense isn't so common any more.

You raise a great point though, it is originating in the engine block and something NH1NH1 should bring up immediately. If it were me, I'd still take it in before hitting 36k. Why leave it to chance.

thanks. I took it in (before 36k), my biggest worry is that it is brushed off and then acts up later and I am expected to pay for it.

sorry if this is off topic but im taking my jeep to the dealer for the casting sand issue and they are giving me a hard time about a rent a car. I remember someone posted something about calling chrysler directly for a rent a car if the dealer wont honor that. Anyone have a number or any info on getting a rent a car?

As long as an issue is diagnosed at a Chrysler dealer and confirmed to be an issue it's covered whether your warranty expires or not.

If it's documented in your service records prior to the warranty expiration date it will still be covered as an existing problem.

My throw out bearing failure was covered over a year after my warranty expired because I asked the tech to note the squeak on depressing the clutch 2 years earlier.

Good luck.

That was me. Dealer kept saying oh we have no cars for you for about a week straight. So i called Chrysler and they said they would reimburse me for the car. I think its called jeep customer care. The division of Chrysler i worked with. I dont have the number off hand but if you google it im sure you can get one.

update: got a call from the service advisor saying that they were going to order a new reservoir and "some other parts" and flush the system. Said that the parts were coming in tomorrow morning and asked if I needed to get anything out of my car. When I asked what other parts the guy I was talking to didn't seem to know but it sounded like that they would be sent a set of parts coresponding with the coolant problem. I'm very relieved and I should hopefully have my jeep back tmrw afternoon.

READ THIS!!! As I am too having these issues and was looking into having my coolant analyzed. This letter is to me from a test facility.

Dear Mr. Simmerman:

Your 2012 Wrangler was probably filled at the factory with Chrysler coolant meeting specification MS9769. The industry knows it by its Valvoline/BASF brand name :G-05”. This German formulation originally developed for Mercedes (that explains why Chrysler adopted it) contains a robust combination of conventional and extended life corrosion inhibitors. It is usually categorized as a “hybrid” formulation. Many hybrids, including this formulation, employ silicate to achieve quick aluminum passivation in the cooling system. Nothing works as fast to passivate aluminum as silicate. However, silicate has limited solubility in engine coolant, and there are situations that can develop which might allow some of the silicate to precipitate. Generally, such precipitation is not critical, but in a worst-case scenario there are known effects such as accelerated erosion wear in aluminum heat exchangers and possible accelerated wear of water pump seals. As evidence, Gates Corporation, a supplier of water pumps to the industry,
to prevent that problem in Gates brand water pumps. Aluminum heat exchangers manufactured using oxygen-limiting brazing methods (CAB brazing) may be more susceptible to precipitation issues.

Amalgatech can attempt analysis of your system deposit. No guarantees here – there is no “magic box” that will spit out everything in the deposit regardless of what it is. We digest it in an acid mix and see if we can find silicon or other metals in it. We cannot identify other contaminates, such as oil. The problem is that we can find silicon, but that will not help you very much because both silicate precipitation and sand/silt from the environment would digest in acid to produce the silicon detected in an ICP analysis. So the data, if positive for silicon, could support either your suspicion or Chrysler’s affirmation. In any case, that is $199 and we accept credit cards. Just harvest about a lima-bean size sample, if you can, and mail to us (address in signature). Put a note with it and we’ll call you when it arrives. An analysis of the coolant from the cooling system ($209) might be much, much more revealing.

A better use of your money might be to discuss with your dealer service manger the possibility of thoroughly flushing the system until clear, and then refilling it with the new Chrysler OAT coolant meeting MS12106. This coolant is an OAT coolant but does not contain the primary inhibitor in GM Dex-Cool, 2-ethyl hexanoic acid, which has been associated with certain premature failures in some vehicles. The OAT formulations are almost immune to precipitation problems. They run very clean for many years. The formulation Chrysler has adopted has been serving well in Europe for almost a decade now, so there is a strong track record. In extreme conditions, you may well see operating temperature decrease when using the OAT coolant hybrids because they run cooler and they have better heat exchange properties.

If we can be of service, we would be happy to do so.

so yesterday the guy said they special ordered parts and it would be ready today in the late afternoon.

called today at 4 and they said it was ready.... get there and they dont have paperwork... say they will mail, i say ill wait... find out that they only ordered the part nothing was installed. got the paperwork and it looks like only the reservoir was ordered... going to call in the morning and find out exactly what will be done. After reading other posts I feel like only replacing the reservoir and flushing wont be enough.

Smart move. I think a good flush should do the trick. I'd like to know what parts they end up replacing for you.

The problem needs to be defined as either sand in coolant or a sludge from the mixing of coolant types. I think most problems come from casting sand, so a flush won't correct your problem if more casting sand is present.
