I was watching my coolant, oil and trans temp on my EVIC screen the past several days while on a long road trip and saw something that seems strange. I have a 2015 PW w/6.4 hemi and was driving on the interstate, flat land, and outside temp 65-70 degrees. Was driving about 70-75.
The oil and trans temp stayed consistent at 215 and 165 respectively. The coolant was fluctuating between ~195 and 212 on a 90-120 second interval (full swing both ways). This would repeat over and over. Sometimes it would just stay at ~210 for long periods of time. Then it would start swinging back and forth again.
What the heck? Is my thermostat causing that issue or what else could be going on. Surely it's not normal.
