Ok I'm back, the car seems to be overheating when the heat is NOT on, what's interesting is that this didn't happen before. I was driving on the highway and the I noticed the coolant temp got to 226, and then I turned the heat on and it dropped to about 200-206. I have been checking the coolant level daily, and the reservoir level is the same (marked it). But when I opened the radiator cap last night (cold) it was between a quarter of a cup short and half cup low. I'm going into a friends shop to do a pressure test in the next day or two, I'm really hoping not, but I'm possibly suspecting now its a blown head gasket. I did have a vehicle warranty with SilverRock and it should be covered for the most part. Anything else I should check before I take it in? Any thoughts?

Ok, I will read it right away and will check it first thing in the morning cold. I have been driving it every day, and its definitely been over 5-6 hours of drive time and no issues at all. Ill read the post now and post back if I have any questions....if thats ok.

Oh wow, mine is a little over 74K miles as well. Same 2.4L and everything I do have a warranty through carvana but I heard its junk, that will be the next step if an issue arises again. Oh wow, dodge actually paid for half? Yeah if it blows at 5 years im gonna be pissed.

I have been driving it every day, and there has been no CEL, misfiring, or overheating. The heat seems to be working fine as well. Am I only checking the coolant reservoir? Or rad cold as well?

Update: I ended up taking the car in early this morning and just got a call from my mechanic, and he said he went through the car, drove it, let it run and etc and no overheating at all. He said there is no leaks, smells, or anything. He did say that the coolant was low, and put in a half gallon but right as of now, there is no over heating after an hour of driving and letting it run. Any suggestions?

I checked the car today, the spark plugs have no discoloration or damage but they were recently changed. I check the oil and there is no discoloration or etc, all the fluids appear to be at the same level and the coolant doesn't have discoloration either.

Ok, thank you very much for the response. Ill check tomorrow when I get in.

Thank you for sharing, I appreciate that. I'll review everything and report the results soon.

It's the 4cylinder 2.4L model, and I'm REALLY hoping its not a blown head gasket. Any signs I should look for if its a blown head gasket?

We did use the OEM spark plugs (copper), as for how it happened it just popped up. We were just driving a few days later and the overheating sound and dashboard light came on. I pulled over and waited 20 minutes and drove it home. As soon as I got on to the block, the over heating light came on again. The car runs and drives fine with no issue, but as soon as it gets to 25-30 mins.....over heats. But just to clarify there is no leaks, smoke, loose connections or etc.

Forgot to mention...approx 74K miles, and no issues with the vehicle ever.

Hey whats up everyone, I'm having a few issues and hoping someone can guide me on what to do next, I turned on the car last week and the engine vibrated for like 30 seconds and then a check engine light came on. It's a 2019 Dodge Journey SE 4cyl 2.4 I got 3 codes. -P0302 CNF MD00 Cylinder 2 Misfire detected -P0302 PND M0D00 Cylinder 2 Misfire detected -P0302 PRM M0D00 Cylinder 2 Misfire detected So I took it to my local mechanic and we replaced all 4 spark plugs, 2 were really bad. But a few days later the car started overheating after 30 mins of driving. I checked the radiator fan, and it comes on when the temperature is reached (approx 200-220), no smoking or etc. My dad and I also inspected the hoses for leaks, tears, all clamps and connections....no issue. Any ideas on what this could be or what we should check for next?

Just want to say whats up everyone, my name is AJ and I live in the windy city. I currently have a dodge journey SE (4cyl) and love it.
