Two words. Lemon law. I'd fight them to replace the vehicle if your stated lemon laws allow it.

 

Just received an update that they are flushing the heating core, getting nervous now

Overall I love my Jeep so I hope this is a small bump in the road. It's been like this for a few months now.

More to come

 

Trust me I have thought of that and it may come down to it, but mine is Deep Water Blue and they no longer make that color. I have customized the inside with colors that I like with that color of paint. I have even made (swen) up some of it myself. I have spent lots of time and $$ getting it the way I want it. That is why I am not wanting them to just replace it.....(just yet).

 

Supposedly there was a lot of silt in the heater core, they flushed it all out and its back to normal

Arghhhh

Hopefully this is a one time problem that is now fixed but not exactly thrilled that this happened with an almost new vehicle

 

I hope it works for you. They did the same thing to mine and it worked great for a few hundred miles then the "slit" would settle back in. I do not want to be negative just don't be surprised if it happens. I do wish you well with it. I know how frustrating it can be!! Sorry I did not read your profile. What kind of JK do you have?

 

I have a ScanGauge Rubi UL 2007 with 90k--numerous long trips--coolent F temp always between 198 to 210 degrees at highway temps--coolent changed at 60k, highest I have experienced is 215 degrees, when offroad high ambiant temp, fans come on and always settles back to F204--likewise, oil temp F 210 and oil pressure between 55 and 60 # depending on RPM which at 65 mph stays at 2350-2400--running factory specs for Rubicon

 

I have a 2010 Rubi Unlimited. Thanks for the well wishes, will post again if the solution is not effective.

Good luck with your Jeep

 

^ x2. My exact thoughts!

 

I wanted to share this with you guys - some evidence - that this is a problem with this engine and model year. I have a 2010 JKU, 29k miles (mostly on-road, I've never forded any water), original owner. My heater has been slowly dying - it used to blow so hot it'd melt your face off - now I'm lucky if the car warms up in 45 minutes.

I've seen the posts about there possibly being sand in the radiators, left over from the casting process. I popped my cap off yesterday, hoping to maybe work some air out of the lines, but I stopped after I looked at the bottom of the cap. It's covered in SAND! Check it out:



My vehicle is under warranty - I'm not sweating too much - but aside from the heating core - what did they need to replace, and why?

 

Y'all can try a coolant filter. The 6.0 ford diesel had this problem and guys starting using a coolant filter setup. I would post a link, but it's to a non-sponsor and I'm too new to get in trouble. Google coolant filter and you'll see what I'm talking about. Best of luck.
