7.3 XLT Tremor
What engine temps are folks seeing towing. I added the coolant temp on top of the gauge in forscan and towing 8k at 80deg Im seeing fluctuations from 180 downhill to 210 on the steepest uphill going pretty slow on side of mtn, 30mph or so. It doesnt stay rock solid like some other trucks Ive had and swings around based on engine load. Assuming thats normal on these 7.3 trucks?

Edit: Nevermind I just read the specs closer above about the thermostat and its not even full open until 212 deg lol. Just used to my Cummins locking in at 190 and holding very steady. Looks like this 7.3 is designed to swing around from 188-212deg which is basically what its doing.
