Radiator fans should be on for a water temperature over 200F (someone should have the exact cut in temp)
Oil temps under 230F are fine the engine will be validated to at least that hot for continuous use and 250F for hot climates.

Some S650's have active shutters on the grill right ?
They do have active shutters in the grill. Upon delivery, my GT (Non-PP) had an issue (reported in dash and in app) that there was a failure with the active shutters (behind the grill). They were fortunately stuck open and not shut. They noted that had they been stuck shut, I couldn't have driven the car for fear of overheating. Dealer ordered the part and replaced, no more error. So they are there.

So, you’re saying that the GT‘s come with Active Shutters? Could you provide a video of them in action please? On my 17’ EB, they would shut on engine off and would be closed when starting up. I’ve watched them open at intervals as the Engine Temps warmed up to Normal Operating conditions. On the S650, even after sitting over night I can still see clearly to the Condenser and Radiator area and I have the PP.

I noticed my temperature gauge on the far left looked a bit high, so I pulled up the details. Everything looks OK as far as I can tell. Inlet temperature is kind of high, as it was 68 degrees F outside. This was about 5 minutes of city driving with several stoplights. (I had already driven it to work earlier this morning, so it wasn’t a cold start.)

Thanks! Wow, captured 1500 miles on the dot... That a full tank? Nice to see others not getting 200 miles out of a tank
I hear ya , mine too gets under 200 per tank at times as well. Best I saw was 270 to empty when I picked the car up from dealer and the last time it was driven was the delivery guy , it was 73 miles drive.

Curious what others are seeing just for comparison. GT A10. Spirited or takin it easy, temps always in this range. Runs great though a day at the track would probably kill it??

This from a cold start, 15 minutes of granny driving, Normal Mode, outside temps 60, no hard pulls, never broke 50 mph

Evening spirited drive, Sport Mode, hard pulls, highway 80mph, back roads paddling through the gears and almost identical to the above granny mode,

Maybe some of you that have more recent Gen stangs can chime in. Last Mustang I had was an 88GT 35 years ago... I guess this Coyote just runs hot? These temps are within normal range though, anything I should stay focused on??
I just took a rather spirited drive around the area. I made several full throttle pulls for about 8 seconds at a time with my 615 mile '25 DH Premium with a 10R80 and Stage 1 Whipple. So I took a picture of the head and oil temps to show what it's showing.
