ive got a 195* thermostat in my 1994 3.0l (26,000 miles on it so all cooling system components and fluids are still new) and occasionally the temp will get to 210* and hover there until i get onto an open road where i can get the air flowing good again. i recently added a 3rd Hella comet 500 to my brush guard and suspected that to be the cause of the higher temps, but after removing it i still have the smae issue. i do have a scan tool and was able to verify that my autometer guage matches the ECMs temps sender reading so its not a case of a rougue gauge or sensor. ive been driving the truck for 2-1/2 years now but it wasnt until this winter that i drilled and tapped the intake to move the autometer gauge sensor from a brass T that i also had the gauge temp sender screwed into (i made the new location on the flat spot behind the thermostat housing). prior to doing this the dash gauge and the ATM gauge both read cold, 160 at the highest on the ATM. when i moved the sensor i also changed the T stat and found that when i built the motor i put in a 180* stat instead of the factory 195*? i changed it out and all was good for the rest of the winter, it never got over 195* and i was happy, but with the warmer temps that spring is bringing im finding my self wondering how hot is too hot?
