It will take 15-20 days as they have to order it from the USA.
Will give feedback when the part is changed.

I will inform the Jeep Dealer on Monday and actaully going to insist that they change the housing as what you will recommend.

I had this problem when wheeling in Colorado. In a at 100 Plus degrees and a hill climb temp gauge would read to 3/4. then drop to 5/8th onthe temp gauge.
I determioned it was a temp control issue hot a radiator capacity issue. The Jeep Dealer in Montrose CO changed the thermostat housing assembly and the problem went away. I tested it on the exact same road with 100 degrees plus temps and never went above 1/2 on the gauge at that time nor on wheeling thereafter. Always 1/2.
A friend has a '12 Rubicon and even with a front winch which block the radiator a little never has a problem in Southern Arizona in the summer.
Hope this helps.

|rvcruzer||Our 2012 Rubicon JKU has never overheated. It warms up fast but doesn't go over where it shouldbe. We weigh in at 5,120 lbs with all the armor on it and the tall Warn Powerplabnt winch on a Rockhard front bumper doesn't impeed airflow through the radiator. We can wheel all day in 108 degree heat in Moab while running the air without worrying about overheaqting. The closest I've come to overheating was with my 4.0 TJ. It would percolate after a long climb at high altitude once I shut it off. The 2012 Rubi has no issues. If your's is overheating then it's time for the dealer to fix it. Could well be something as simple as a thermostat.|

Jeep Tested the Rubi today. Tempreture at Normal operating is at 104 degree C and goes up to 115 degree C with a little up hill (3/4 position).
They also saw that it is leaking a bit on the coolent bleed screw. They still want to check if the thermostat is not sticky and at what tempreture the fan kicks in.
Will keep you posted.

I am in the engineering industry and a waterproof electric motor is not difficult to get.
I know of other manufactures that have no issue with theire electrical fans.
And I thought the Rubicon is trail rated!!

i use the cable from gopoint mentioned above. there's also a BlueTooth transceiver.
I like the dashcommand app for in car use, clearing codes, etc..

I've collected these numbers using the ODBII reader on iPhone.. louvers dropped my cruise temps from 220 down to 196. Being able to run the fan for 5-10 minutes after shutting down would make a huge difference. Could add a timer, maybe when i install 2nd battery?
Cat temp swings from just under 1300 cruising all the way to almost 1600 at full power!
|08-08-2012 01:23 PM|
Yes the fan kicks in and you can hear when it is on Speed 1 and on Speed 2.
So is the 2012 Rubicon Fan not waterproof as well??? WTF?????
This car cone leave me in Africa. Good to know. I will take the steelers on, on it as well.

|Peepers||And this is why a lot of manufacturers are replacing all the gauges with idiot lights...|

|N3M0||my needle always seems to be a hair to the right off middle no matter what kind of driving im doing.|
|08-08-2012 12:58 PM|
The needle stays in the middle from about 180 deg through at least 250deg, doesn't mean much.
In my experience the only way to see such high numbers is after you park the vehicle with the engine turned off, it climbs like a rocket! there's some truth to opening the hood after wheeling.. or install PoisonSpiderCustoms Louvers.
Your Fan may be busted, have you gotten much water in it? the OEM fan isn't waterproof! there's a thread around here somewhere with a replacement recommendation.

|daggo66||Have you heard the electric fan come on at all?|
|08-08-2012 12:47 PM|
This is not acceptable for the era that we in and for me then, that heat gauge is off ZERO meaning for me. I had several cars in the past. Non of them had a temperature gauge that fluctuate for nothing. Where will the temperature gauge go when I hit a very long uphill.
When is it a warning for you that the car is running actually hot??
|08-08-2012 11:22 AM|
|ferninAZ||I have noticed that my needle is to the left of the middle line but still touching the line during daily commuting. I live in AZ so it is a little warm pretty much all the time. When I am off roading, specifically when going up hill in 2wd or 4wd hi at low speeds the needle passes the center position and moves to what I would say is the 60% position. Thanks Chrysler for not putting numbers on the temp gauge. When I return to a downhill position or switch to 4wd lo, it moves back to its regular driving position.|

|tomthbomb||With 18k miles on my '12 the needle has never gone over 1/2. Usually it stays 1 click below half.|

Jeep call today and said they had a look when I had the car yesterday with them and the plastic cover that is normally under the bumper is not there and they think that is the cause of this.
I have a Mopar steel bumper on my Jeep Rubicon 3.6
I just think it is a joke. Let the game and fun begins.
Laughs actually for them

Hi I am from South Frica and have a 2012 Rubicon.
Tempreture yesterday was 1°C. When I tow my off road trailer the head gauge go to the 3/4 mark. When it hit the mark I am over the little uphill. Not a serious hill at all.
The trailer is 1ton.
Rubicon have 4000km on the clock.
Any answers on this problem so far?
JEEP want to connect it now to a Y TECH machine.

|azpics||Just heard from a friend who took delivery of a 12 Rubicon unlimited and wheels in Southern Arizona in fact ast Friday when temps were well over 100. He said he has no increase in temp at all and needle remains on 50% all the time. So guess I do have a problem.|
|06-27-2012 11:23 AM|
|pluke the 2||our 12's rubicon transmission runs 25-40 degrees hotter than our 2010 sport does.|
|06-27-2012 11:21 AM|
|azpics||Rhrodyjeep: that is a good question and one of my main concerns. But, since the temp does fluctuate even while in traffic still think it is more a temperature control issue rather than capacity. Thanks|
|06-27-2012 11:18 AM|
|azpics||The level is at max was the first thing I checked. Thanks|
|06-27-2012 12:29 AM|
|Rhodyjeep||For comparison reasons only, and in line with the OP's question, does anyone know the difference (if any) in core size/width of the radiator between the '10 and '12? Not apples to apples, just curious. I'm not sure of either size.|
|06-26-2012 11:28 PM|
|SilverSport||Ok, I have to ask. With the engine cold is the radiator full of coolant and with the engine hot is the coolant in the overflow reservoir at the "maximum" mark?|
