Debris in radiator overflow canister

So I was looking under my 2013 JRU with a drop light and noticed what looked like debris in the bottom of the over flow canister. I dropped a clear hose in the canister and pulled it out and there was a light brown sludge that was covering the bottom 1" of the hose. WTF any one else seen this?

That's very common. Nobody knows for sure what it is. Lots of guesses, though.
See if you can get it analyzed somewhere.

Sometimes it's bad enough to block the heater core, and even the radiator.
There is a TSB to direct the dealer technicians through the repair procedure if it's an issue.

It looks like possible stop leak. Most manufacturers put it in upon assembly. The pellets seem to be the popular choice of ford an GM not sure about Chrysler.

Well I dropped it off at the dealer.... printed out the STAR (poor heater performance) which tells them to replace the radiator and heater core if sludge is found in the overflow canister. I also supplied them with the TSB regarding the wrong fluids used in the cooling system....should be purple mine is orange. We will see what they say!!!!

In case any one was interested they found a 17 degree split in temp between pass and driver side and debris in the cap and coolant reservoir. They are replacing the radiator, cap, heater core, engine oil cooler, and thermostat. They are also going to flush the system prior to replacing components and put the purple coolant in.

I know this is a post from January but I just discovered my 2013 Jeep Wrangler Sahara has this issue I went in to the dealership due to the heat not working. They have to take the motor out and replace the heater core and radiator now I'm worried I'll have issues from here out since sand like substance has went through the motor hAs anyone had this problem and had the repair done? Just wondering how your jeep is doing after the repair... Thank you!!

I had it fixed about 2 months ago. Replaced radiator, heater core, oil cooler and flushed the whole system. The engine does not have to be removed but the entire dash get removed, and a good part of the engine disassembled. Make sure they put the good coolant back in (purple stuff) good for 10 year 100k
