2019 Cylinder Head Temps

[Torchy]

Hey guys,

Have had a this 19 for about 2 months and just started monitoring CHT about 2 weeks ago. Noticed this thing runs HOT!

Average is about 220 degrees in 40-50degree ambient temps. Over Christmas I was at my cabin driving through the mountains in 10 degree ambients (yes there was elevation and lots of hills) and it would run as hot as 239 and averaging 230-235.

That just seems high. I added Redline water wetter and might have seen 2-5 degree improvement but other than that the truck is bone stock with about 1200 miles on it.

Do they all run at these temps?

Side note, I'm not a noob, this is also me.

Are you using the info screen in the dash cluster to show those temps?

2019's get a bunch of possible gauge readings that are not available in the 17-18's.

Boosted engines run hot.

Not sure if the 3.5 EB has an oil cooler but a great idea if you want to thrash the Raptor.

195 to 220 is normal for any CHT under normal driving conditions be it a Ford or Chevy. I wouldn't be concerned

I wanted to be sure where the info was coming from either the truck display OR maybe a gauge/display device. There's plenty of options out there.

Yes using the screen in the dash to see this data. 802A

I should have worded my OP better. About the lowest it daily drives at is 220. 225 to 230 is very normal for me to see. That is hot.

My daily driven TT5.0 runs at 198CHT. It makes 3x the power of the 3.5EB

You could always put a 170 degree thermostat in... stock is 195.

I checked mine yesterday, similar to yours under normal driving. While I didn't think to look at the AFR numbers at the same time I would bet that as the AFR goes down under boost the head temp remains stable or goes down with the fuel cooling effect and timing being pulled. Light throttle and low RPM lean is probably the highest head temps for economy and emissions. The gauges are surprisingly responsive for stock. Slightest throttle blip and the values change.

I was wondering the same thing about cylinder head temperature. Snapped this a few days ago
