Hello everyone, I had just purchased a 2017 Ram 2500 HD 4x4 with the 5.7 Hemi. Love the truck so far as it is able to handle all my needs perfectly. About 2 weeks in now to owning it and I just started to notice the coolant and oil temps being a little high at times. At highway speeds the oil and coolant reads around 195F - 205F, but as soon as I get off the highway and sit at a stop light or drive at low speeds in stop and go traffic, the temps start to climb. The highest I saw them reach was 235F for coolant and 230F for oil while idling parked with them steadily climbing higher. After seeing those temps I started to drive again and the temps went back down. I have no Idea what the correct temps are supposed to be for this engine and truck set up. I scheduled an appointment with the dealership as I am still covered under warranty but would like suggestions on what could possibly cause these issues. Thanks.
