Coolant temps.

[SilvererSHO]

What are you guys using 170F thermostats seeing for temps going down the road in 80F weather with the AC off? I just got my Livewire TS+ tuner Monday morning and am surprised to see temps around 185F at the lowest. As soon as I pull off the main drag I'm seeing 210F-215F Turned the AC on when they spiked and the temps came down. So methinks I may have a fan out. Funny the gauge on the dash hardly moves any though so I'm surprised at the numbers I'm seeing. My tune showed up today and I want to figure out if anything needs attention before I load it hopefully on Friday. I'm also afraid of the voltage numbers I'm seeing, 14.1v at the highest and low twelves as soon as I turn it off. Doesn't it fault out at 12.25V when loading tunes? I thought I remembered seeing that in the user manual. Or is the "module voltage" lower than battery voltage and it's nothing to worry about? Anybody hook up a battery charger when loading their tunes as a safe measure?

Sounds very similar to what I'm getting for temperatures.

I have on my f150 Ecoboost. There is a thing ford does that limits charge to 80%. So technically are batteries are never at 100%. Something you can disable with forscan. But forscan has a warning pop up before trying to change setting to get charge to 100%. So to play it safe I used a charger on mine at just 2amps. I just couldn't risk being halfway through changing registry's for truck to die. Doing the same with my SHO by having a charger on it as well when doing it's tune. I used a charger while using forscan to make some changes. Going with a charger is because of a lesson learned. I've bricked one of my cars before when it shutdown while I was using forscan to make some changes to the as-built data. I had to reload all of its as-built data to each module and PATS just to get her to start. Not fun, windows were up, it was 90 outside and had to sit in my car for an hour while reloading each module. she had lost her stored administrative keys so I couldn't even roll down the windows while uploading because without those IAK fobs being recognized, you cant go into accessory mode. Turning this long story short,,, my opinion, a charger is a lifesaver.

Similar temps here as well with the 170 tstat. Presumed it opens up at 170 rather than the higher temp, not that it attempts to hold 170 as a high end range of temperature. I may be wrong with that assumption but it made more sense to me to prevent a spike before it happens....opposed to trying to keep it below 170 which would be ******* the water pump.

Man oh man wow. Difficult for the pump smh

I was driving at 70 mph in 80 degree temps with my a/c on and coolant temp was at 179-180. And trans temp at 197-198.

I'm not seeing the spikes to 215F anymore since I loaded my Gearhead tune. I'm still surprised the temps are not well under 185F with a 170F stat going down the road.

Before loading the tune your fans were still set to come on at like ~210 degrees. Setting in the tune will be lower.

170° is the point where the stat begins to crack open, and goes full open around 180°. What you're seeing is perfectly normal, 180° to 190° while cruising. Keep in mind that your water pump is tied to engine speed, so at cruising speed your system's cooling capacity is greatly reduced because there's relatively little coolant flow. When cruising put the shifter in sport mode and downshift a couple gears; you'll see coolant temperature drop 5°-10° almost instantly.

You'll still see well above 200° after a 1/4 mile run though. Don't be alarmed by it.

You know I still see 210-220 at times. Especially if idling, or getting on it when 85 degrees or better air temps. It goes to 190 ish pretty quickly after when cruising normally. Fans operate way more often
