Journey 2021 Posted November 9, 2021 Report Share Posted November 9, 2021 Hello, I have a 2014 Dodge Journey and here lately the temp has been running a little higher than normal. When I turn on my A/C it seems as if it helps at times but others it seems it is causing it to run hotter. If I am still at a light it seems to go down in temp but when I am driving for long periods of time if seems to also run hotter. I recently have started using my heater which has help with the temp and it stays at a lower temp. I have no leaks and radiator and overflow is filled where needs to be. Any ideas on where to being?

larryl Posted November 9, 2021 Report Share Posted November 9, 2021 Thermostat failing to open properly? you dont say if its a 4 or 6 ?????????????? Quote Link to comment Share on other sites More sharing options...
2late4u Posted November 9, 2021 Report Share Posted November 9, 2021 also how many miles as well?, probally needs a flush and thermostat replaced with new oem rad fluid would be your first best option to start with Quote Link to comment Share on other sites More sharing options...
John/Horace Posted November 9, 2021 Report Share Posted November 9, 2021 Analogue dash gauge or cluster exact digital temperature. Quote Link to comment Share on other sites More sharing options...
Journey 2021 Posted November 9, 2021 Author Report Share Posted November 9, 2021 It is a 4 cyl 2.4L, it was just flushed in July/August, it has both a gauge as well as a digital and it has 129500 Quote Link to comment Share on other sites More sharing options...
5rebel9 Posted November 9, 2021 Report Share Posted November 9, 2021 The 2.4 motor uses TWO thermostats. I'd start by replacing BOTH. 2late4u and larryl 2 Quote Link to comment Share on other sites More sharing options...
Appalachian Journey Posted November 10, 2021 Report Share Posted November 10, 2021 Was it overheating before the flush? Did you do it or have it done? If the flush wasn't thorough and the wrong type of fluid was added it could be gelling, slowing flow or clogging passages. Quote Link to comment Share on other sites More sharing options...
John/Horace Posted November 10, 2021 Report Share Posted November 10, 2021 Are both gauges showing the high temperature, is what I was asking. Always start with making sure glycol level is ok, leaks can cause low level and temp variances. If you are changing thermostats ( they are a wear item and it may be your problem) buy the coolant assembly that has both engine and cabin temperature thermostats in it, cheaper way. This assembly tends to leak at higher mileage, it did on daughter in laws 2.4 engine. Assembly not hard to swap, took me about an hour total. Temperature gauge can be moved over to new assembly, it doesn’t come included with new set up. https://www.rockauto.com/en/catalog/dodge,2014,journey,2.4l+l4,3038628,cooling+system,thermostat+housing+/+water+outlet,10337 Quote Link to comment Share on other sites More sharing options...
Journey 2021 Posted November 10, 2021 Author Report Share Posted November 10, 2021 Yes, it was heating up before I took it to get a flush done, I did that thinking it would help but did not. Yes both gauges are readying the same temp. There are no signs of leaks when it comes to the water pump, hoses, radiator or anything else associated, and radiator is full check it every couple of days just to make sure. I will start with looking into changing out the coolant assembly since I am able to do a lot of mechanics on my own lol. Thank you everyone for providing assistance. I will let you know the out come. I have had the car for 3 yrs and I know none of the small wear and tear thing haven't been replaced for a while at this time. Quote Link to comment Share on other sites More sharing options...

Yes , with the T-stat housing being made of plastic sometimes it may be best to replace the whole unit as posted by others. Either way, TWO new thermostats.

John/Horace Posted November 11, 2021 Report Share Posted November 11, 2021 My daughter in laws 2012 heat/cool manifold had a small leak which is why I changed it. The Gates assembly came with a new large 1.5” diamo ring for back pipe connection. Cooling temp probe on top is reused and moved over to new assembly, new small 3/8” ish oring for that was not included. Found one on a universal oring assortment kit I have. Buna material. If you buy each gasket and oring and thermostat and thermostat seal individually, it’s more than double the cost. There will be a Mopar assembly available as well.

Journey 2021 Posted November 15, 2021 Author Report Share Posted November 15, 2021 Well after spend some money this weekend for new water pump, upper hose assembly with thermostats and serpentine belt it helped a little but still heats up to about 230/240. Will be taking it back to the shop for a different mechanic to take a look and see what else could be wrong. I am now almost thinking it could be the block temp sensor.

John/Horace Posted November 16, 2021 Report Share Posted November 16, 2021 (edited) That’s why I was asking about both gauges. If the analogue sweep gauge beside steering on left is at half, then it is running normal and probably ok. Digital gauge just wrong. The main engine thermostat for cylinder head is 205 F, so 240 is high and electric fan should probably be running and car over heating. 205 F is the start to open temp so it will over shoot a little. I didn’t change temp sender in cooling assembly, just moved it over to the new housing on daughter in law car, swapped oring. Fix was just for leaking seal issue. Even Mopar sender is only $23. A cylinder head gasket leak could allow air into system and cause overheating. Pressure relief would be venting as well. Hope it’s just a band sending probe.

Journey 2021 Posted November 19, 2021 Author Report Share Posted November 19, 2021 Well, after a return to the mechanic I ended up with free parts and labor but have a new radiator and fan with motor, due to the mechanic missing some stuff with the diagnostics. Nor it runs between 195 and 210. I have had the car for 3 yrs and it has never ran that cool so it is pretty nice. Thank you all for your help. 2late4u 1 Quote Link to comment Share on other sites More sharing options...
