So there's a filter for the cooling system?

Bro...

I would approach them with a copy of the "lemon law" in hand.

You would have received it with your original purchase papers.

You can get a copy on line.

No, not initially. The dealer installed a filter into the heater core hose the first time in. It was removed the third time in clogged with sand and a finer material. Now the heat blows hot. I don't know what it was but casting sand seem to be the consensus. The dealer can't seem to give me a definitive answer. And I have no idea how much more of that stuff is in there.

Scary stuff. I hope you get it resolved. Honestly, I hope you get satisfaction via the lemon law. I know I would feel sick making payments on (or having paid for) something that had been cracked open several times before it was a year old. They are never the same once you crack them up IMHO.

Non-functional heating

Hello owner jeep,
*
It's been 5 times that I go to the dealer for a heating problem in my jeep wrangler 2012 40.000 km. Now the engine heat and the indicator light in the dashboard flash. I was in another garage to obtain other information, the added filter is clogged with somethings look like brown slime. I live in Canada and temperatures regularly below -20 degrees Celsius (-4 Fahrenheit), so this is a major problem. Does this problem definitively settled by any of you?

Thank's

I have asked this before on here and met with only negative comments, but still want to know. Why in the world in Chrysler requiring HOAT and OAT. Check out all the coolant problems on this site! If you are running HOAT and you or someone else mixes it with OAT you are looking at a minimum of a new cooling system and at the max a new engine! This is BS! I understand the poising of small animals stuff, but in the past 50 years I have had over a hundred cars, have never poisoned a small animal, and have not had a cooling problem. Why can't the system be flushed and run standard coolant which has been around for decades and does not turn to sludge. Some have suggested that standard coolant will dissolve the 3.6 gaskets! What are they made of, jello? Coolants today are compatible with copper, aluminum, iron and every other material known to man and are running through millions of cars without any problems. This crap is failing within the first few hundreds of miles in some instances. I just don't get it. Unless someone can give me a good reason not to, I'm draining mine and running Peak or anything I can find at the parts store. I don't want to hear "warranty". If the engine fails I will redrain it and refill with HOAT. This looks like another of those major fuckups out there in the world with my name all over it.

i had a 2012 challenger that had the pentastar 3.6 and Dodge sent me a letter saying they're having issues with the heads and gave me a 10 year warrantee on it,i don't know if it pertains to the jeep. i would go to another dealer but Google it and print it out then you have some ammo to go with
