We have had this dart since February 2019, in June 2019 it started giving us crazy weird issues, after we noticed the fuse box had caught fire. First started over heating, check engine light came on, told us to change the camshaft position sensors. Did that. Then kept overheating, told us it was the thermostat housing, changed that. Then drove it for about 10 minutes, and it just kinda stopped running in the middle of the road, and would not start again. And the starter reaked, so of course that was fried. Went and replaced that and the knock sensor plug. And finally got it started, and then it was running good for a while then all of a sudden there was white smoke out of the exhaust, steam going into the cool air intake, and antifreeze in the oil. Well we have no more of those issues, but everytime we seem to put the overflow cap back on, we end up popping off a radiator hose, for whatever reason. It does good, until it starts building up pressure, but it seems to build up way too much pressure, and its becoming a frustration, and running out of options. Please help!

The pressure in the cooling system is from leaking compression. The head is likely warped from overheating. Replace the head gasket after having a machine shop check and resurface the head. Or find a junkyard engine.

Is it possible foe it to just be the head gasket? Its weird cause when we put coolant in it, after not letting it run for a few hours, it cycles normally, but after a little bit, the heater blows cold, and then if you start to squeeze the heater core hoses it will start to boil, like something is blocking it real bad. But doesnt overheat.. We havent had this car long at all, we are suspecting it has had a blown head gasket since before we purchased it, cause it has always overheat. Before all this started happening it was extremely manageable to get the temp to go back down, but now it goes us and its a pain to get it to cool down, but then the cel will come on with the code foe the heater circuit relay, but when the fuse box caught fire, that's the relay it burnt up... But we replaced it just barely, unless something is happening to continue to make that relay have issues..

If you have one of the MultiAir engines, this may be beyond your capabilities.

There is no other way for that much pressure to happen. The white smoke tells you coolant is entering the cylinders.
Look up the UView Airlift tool to see the correct way to fill the cooling system without trapping air.

So still having the pressure build up, but none of our caps seem to be working for us at all.. But went to go get to the water pump today, hoping that might help slightly.. And found the coolant temp sensor, broke all to hell.. The wires werent even attatched at all, what would cause that? And keep having a check engine light for the relay that runs the cooling fans etc. Our cooling fans wont come on, and we seem to have this problem ever since the fuse box caught fire to the wires that go to that relay.. Ive never seen or heard of a fuse box catching fire, we went to dodge and went to insurance and still have yet to hear something back about it...

The coolant temp sensor is part of the thermostat assembly on the driver side of the engine. The water pump is driven by the serpentine belt on the passenger side. Are you sure you are correctly identifying things?

From my knowledge yes, an engine coolant temp sensor, behind the water pump, unless it is something else? Looks exactly the same as one in the thermostat, just different location

You are looking at the oil temp sensor. Same schematic I have posted previously.
If you have burnt wires, there is a short in the wiring. Throwing parts at it does not fix shorted wiring.

There have been reports of engine bay fires in almost every modern vehicle. With so much electronics, it just takes a short somewhere. Usually a fuse will blow, but there are some high amp fuses that can let things get really hot before blowing and set neighboring flamable things on fire. A good mechanic will know how to read a schematic and localize the problem circuit. If you are intimidated with electrical stuff, find someone who has the experience.

Well and this is all factory wiring, nothing's been changed or upgraded. We tried to contact dodge about it but they won't say anything

Try a different FCA dealer. Some dealers are only about selling cars, not fixing them.

We just went to dodge customer support, and had an insurance claim open for it on our insurance, and the adjuster still has yet to come and look at it even
