5.9 operating temperature
Thanks for all the feedback guys.
As N/A I always thought mine ran hot, creeping past 200 with a 180 stat. I'm turbo now running E85 and it's still climbing up to 210+ in traffic. Obviously all the turbo components under the hood add heat. I just bought a high volume water pump and 160 stat. I have an electric fan, 3 row Champion radiator. I control the fan from a switch. Going to see if the pump and new thermostat help.
