Engine Temperature
2018 GC Summit 67500 miles. I regularly take the Jeep in for service and most recently had the spark plugs replaced, coolant line flushed and replaced, break lines flushed, oil change for $1590 all of this done at the dealership closest to my house then the engine oil cooler replaced which included the upper and lower manifold drain and refill was done by the other dealer I bought the Jeep from which they replaced for free.
Twice now I have gotten an engine too hot notice on my dashboard and the temperature gauge is well past halfway. I immediately pulled over and turned the car off. When I turned the car back on the engine still read hot so I turned on the hot air full blast and the temperature gauge started to drop to its normal level. Once back under half reading in the gauge I turned the air conditioning back on and everything seemed to be ok. When I got to where I was going I had the car running idle for a couple min and again both the trans temp was at 199° and the oil temp was 220° and the temperature gauge began to slowly increase as I am just sitting in the car.
The coolant levels look fine and are at the required levels. The radiator lines don’t seem to have any leaks and there is no leaking of any fluids in the engine bay that I can see. I am wondering if anyone else has had issues like this? I’m thinking it could be the thermostat, but not sure why the other levels temperature would rise so rapidly.
Any advice would be greatly appreciated. Yes I know the advice will be go back to the dealer, but every time I go it’s a minimum of $200 for them to look at an issue and would prefer to try and identify the issue myself if possible as I can’t just throw away $200 each time I go.
