I have a 2017 Dodge Journey ( fiat ) 2.4L

I bought this a few months back and I noticed during the winter months there was some yellow residue that would accumulate on the oil fill cap, unfortunately a powertrain warranty doesnt cover head gaskets, so I guess I'll just have to wait until the engine breaks down.

But that just caused me to pay more attention to the new "oil temperature gauge", after driving just 30 miles my oil temperature was reading 199, my coolant temperature was 197 and my transmission fluid was 105

Are these normal reading for such a short distance, I would of thought the oil and coolant combined to dissipate the heat wouldn't let it past 150 but then again, that's why I'm here.

The yellow residue is common and normal. It's water from condensation and it easily happens when there are cold periods followed by warmer and more humid periods.

It's only when there is a huge amount of this coupled with water/coolant in your oil that you have evidence of a problem.

The best solution is to drive the vehicle for an hour or two regularly to allow the engine heat to drive out the excess moisture and to change the oil per the manufacturer's recommendation.

The temparatures is normal,coolant temparature is 197F=91C so this is spot on what it should be.

Oil temparature is fine too,it is often a bit higher than the coolant temparature and this is normal.

The transmissiom fluid temparature is fine and it show your transmission is in good shape,105F=40C it is in the low range so no need to worry.

A tiny bit of gunk under the oil cap is normal if you only drive short trips so i do not think you can expect the head gasket to fail any time soon.
