what is "normal" coolant temp on a gen 2

[nikhsub1]

That is too hot for my liking. This is why I put a 170 degree thermostat in. Never see above 200.

I know this is an old thread but I have had my truck since December and I am new to ecoboost and have been concerned about coolant and trans temps. Being that I am old school looking for lower temps as a norm, this motor might be very different. I agree that cooling the charge air is good for performance, the engine oil and trans fluid may not need to be what I am used to. We may be trying to fix a problem that doesn't exist. Found an interesting read.

See what you think.
