JustDodge Posted June 22, 2022 Report Share Posted June 22, 2022 I have a 2012 3.6 Journey. I got it almost two weeks ago and I’ve noticed that the engine temp constantly rises above normal. It’ll go back and forth between the 2nd-3rd dash past normal and the fan constantly cuts on. I can be sitting and temp will rise and fan will cut on. It’ll stay on for about 30 seconds then temp would go down and would cut back on seconds later. What could cause this? I am supposed to take it back to the dealer because the engine light is on due to it needing a new oil pressure sensor but not sure if those issues are related.

tsteves5 Posted June 23, 2022 Report Share Posted June 23, 2022 I've owned a few of these 3.6 engines in different vehicles and it's not uncommon for the temperature needle to go a little above half during the summer with the A/C running. Look at the actual temperature that is being reported in the display menu. I don't think I've ever seen mine go above 230 degrees, even climbing mountains. If yours is going higher than that, perhaps it's time for a new thermostat or possibly a temperature sensor. 2late4u 1 Quote Link to comment Share on other sites More sharing options...

Only experience this issue with one, they’re both driven on a daily basis in the same temp weather. So it’s just odd and confusing to me why one acts differently. It’s always above normal so you just constantly hear the fan on. I can literally start it up in the morning the car would warm up and kick on the fan… Quote Link to comment Share on other sites More sharing options...
John/Horace Posted June 24, 2022 Report Share Posted June 24, 2022 If it’s acting like it’s hot right at cold start up, not likely mechanical thermostat. Electrical temp sensor giving bad signal maybe to fan control relay. Dash analog gauge is best indicator of engine temp. Quote Link to comment Share on other sites More sharing options...
