Does anyone know the normal temperature range for an ecoboost cylinder head? Just curious due to a readout on my edge CTS gauge. My truck isn't indicating a high temp but the CHT is showing high on my CTS readout. Any input?

when the engine is at operating temp it should be around 190-209 Fahrenheit. I've never seen mine go over 209.

CHT is not the same as operating temps...once you start nearing 400 degrees you start hurting parts on most engines. Don't know where are engines tend to reside...

I'm out in the Arizona heat where the
ambient temperature is 110 on average. It reads upwards of 235 degrees. I guess that's well below 400 so I won't be too worried.

CHT plus EGT readings combined are great to know if you are towing...the best way to tow safely.

I know for a fact that the 2009-2012 F150's use a cylinder head temp sensor instead of water temp. So the numbers I posted should still be valid.
