With +/-5% the 225-245 degrees would mean 203-252 degree swing. My truck never dropped below 225, by my reading. I thought it was the thermostat. I know this engine runs hotter than my other vechicles. I removed the 4 shutters to lower the temps, I replaced 2 of them. I finally found a 195...
I know this post was almost a year ago. Which ones did you remove? To keep it from throwing codes you need to leave the top and bottom ones on both sides in.
tfeni52355, My truck always smelled like that. It put off so much heat when I got out, even after a short trip, it would reach 225-230 in less than 5 minutes. I was told stock thermostat temp is between 203 and 210. The temp of my truck never dipped around those temps.
I removed 4 of my grill shutters so my 3.6 pentastar in my 2014 would run cooler. My truck runs much cooler, but my thermostat never opens. Now the temp runs between 186 and 198. Any mechanics that could let me know the down side of the truck never running hot enough to open the thermostat.
