sounds like your problem started after the heater core replacement and new stat...wonder if he used the right thermostat as it sounds like it is stuck open and not letting the engine to warm up

as mentioned make sure there is no air in system,very important.....also does your journey have a temp gauge that tells you what temp you are at,,,what i am saying my journey has the dial temp gauge and it goes exactly 1/2 way between cold and hot and also a separate display in the menu that tells me the car is at 199 degrees or 203 degrees or whatever the eng temp is,,sorry not familiar with the early models,,, IMPORTANT what was the problem before the thermostat change did you have heat then????

so who did the work you give us no background on your journey? engine size and miles? are you doing the work yourself and what is your work capacity. is the journey driving okay,is it running cold ?what is the temp gage showing my 2014 3.6 121 k i just had to replace the thermostat due to the engine check light came on running to cold.

decided to pull the overflow tank just to clean it out, just 2 bolts and remove the clamp on the inlet top side,and i removed the ckamp on the hose where it attaches to the aluminum pipe towards the front middle of the fan and motor made it real easy to remove it...LOL the tank after draining it look real clean guess it was the dark MOPAR antifreeze that made it look dirty...LOL oh well its done now but had to rebleed the system but that is a snap with the bleeder screw,,just be careful with the tank it is around $80-90 replacement thermostat must have been going bad For a while as man the heat sure seems a lot hotter now

well i did the 3 cold to hot starts and eng light was still on,some say on youtube it has to be turned off with a scanner,so off to oreillys and asked the same kid to turn it off, he was kind of hesitant but finally did after he saying look i buy all my parts here,then i took it for another long drive no lights and everything acting normal, we were going off on a trip next monday so it was weighing on my mind wanted to get it done...LOL

might try disconnect the bluetooth fuse some have reported that ended up being their problem

welcome to the group

well the old check engine light came on coming home from a lunch out,,got to checking all my temps and gages and the eng temp running around 170-175 so stopped at a parts store they checked and said either thermostat or temp sensor,so the journey normally runs around 195-198 so i picked up a new thermostat and gal of antifreeze, got home and thought this will be a breeze since its a 3.6 but damn that bottom bolt is hard to get to and they made them so long, ( at least thats what she said) took a while longer than i originally thought but finally got it changed out and really didnt lose that much fluid, added a bit of fluid and started up the journey with the heat on and opened the bleed screw a few times and then cleaned up everything and took it for a drive, didnt take long and the gauge was reading 199- 206 and was blowing good heat out the vents took it on a long drive stopped a few times to see if any ,more air in the system but nope all good the eng light is still on and stopped by parts store and they said it will go off if everything is okay after 3 cold-hot start and stops, i knew they could turn it off with their scanner but they didnt seem to want to ,,,,,pretty sure this will fix it hope its not the coolant sensor but this was the easiest fix so started here but dam that coolant cost more than the thermostat 19.99 for the stat and 20 something for the correct fluid

tapping on the actuator and or unplugging it and then replugging it has been mentioned on fixing them for a while

actually just last week on my 2014 i removed the plastic covers under the hood and in front of the windshield to remove and clean the leaves that had collected there,it looked worse than it was actually, man what a bunch of different kinds of push pins they used in such a small area (4 or 5 different kinds) good thing i had bought a assortment of pushpins of amazon for such cases for replacement..........as far as the cabin filter i bought a washable K-N filter so i always clean it every 6 months it has paid for itself many times over

since you just replaced the alt i assume you disconnected the battery cable and then this new problem started up i would remove the positive battery cable at the top post and let it set for a while and then reconnect ,kind of like rebooting your computer and hopefully might rest or fix the problem....good luck

also check the connectors on the fan wiring for a bad connection or shorted wires,yrs ago my daughter had a dodge car and was overheating and the cause ended up being a bad connection from the wire connector going to the fan thus letting it to sometimes work and then not work (was melting/shorting out on the inside of the connector we hard wired it back together and all was fine

i would be suspect the fan to see if it is coming on correctly ,,,and also you say it is loud that right there is enough to check it out before replacing any more repetitive parts like you are doing now

people can find out anything on youtube these days and how to fix it,i am surprised so many dont check that first, i watch fix it angel and South main auto repair the most just interesting to see them do the repairs...man if we would have had youtube 23 yrs ago it would have been great

thanks Summer for pointing that out to them, i wasnt that clear on how loud it should be, i did yrs ago replaced a blower motor on a caravan i had and after replacing it, it would click fairly loud for about 5 seconds or so but it was such a pain in ass to put in and i said to hell with it , i could live with the clicking noise once a day, surprisingly it never tore up and worked fine till i gave it to my granddaughter and she never had any problems with it as well

welcome to the group, that is your blend doors resetting themselves all is normal,,they all do it you can google it if you want

LOL i guess all the journeys with this problem isn't a safety hazard.............................(The Hill) – Tesla has recalled nearly 500,000 U.S.-based vehicles due to safety concerns. In a letter to the National Highway Traffic Safety Administration (NHTSA) on Wednesday, Tesla said it plans to recall 356,309 Model 3 vehicles made between 2017 and 2020 over concerns that the car’s rearview camera cable harness may be damaged by the opening and closing of the trunk, which the company said could prevent the rearview camera image from displaying.

as mentioned above replace the thermostat as it is real easy on the 3.6 and ues the rng temp should read 185 at least after being warmed up,,,,dont forget to bleed the air as well after replacement. if you are still not getting enough heat from the heater could be the heater core getting plugged up as well check out youtube for the quick and easy way to replace the heater core

welcome to the group, I had a 2011 mainstreet as well ended up trading itin on my 2014 crossroad had 70 k on it when that happened no real problems with it except the undersized brakes they were replaced by the dealership and then didnt have no more problems with it,,,take care and enjoy your ride

that part that broke was probally the battery temperature sensor and that will keep a car from running...is this the part that was broken on amazon....Battery Sensor Compatible with 2011-2021 Chrysler Jeep Dodge Ram Replaces# 4692269AI Battery Temperature Sensor

best to go with OEM mopar part, my dad yrs ago bought an alt from a local auto part store and had it installed on his caravan and kept having problems with it and the mechanic changed it out several times with a replacement from the store, and finally took it into the dealership and they told him on the engine and yr he really needed to go with a mopar alt ,so he said do it and got his money back on the auto part store one and he never had any other problem with that van or the alt.

here in the states we tend to forget how expensive things are in other regions of the world, we bitch about a $20 delivery charge if we get charged that

`i wasnt trying to be uppity, I just was saying with cars getting so expensive and complex that is why i purchased the warranty, i still like to work on my vehicles but most repairs are getting past my ability or ambitions..

well since its a MOTOR mount bracket only have a few spots it can go

glad i bought the mopar max lifetime warranty
