*Engine Coolant Temp: Coolant temp. Normal 190-200*, Heavy Service 200-215*, Alarm Set 230*. If you are seeing temps under 185*, you may be seeing a thermostat that has failed open. While not a condition that will damage the motor, these trucks operate more efficiently at the 190-200* range.
*Engine Oil Temp: Oil temp. Normal 5-15* above ECT when at operating temperature. Engine will defuel at 254* and go into limp mode. This is the critical value to watch, as it relays the health of your oil cooler. A spread of 15* or more between the ECT and EOT is the threshold for an oil cooler replacement/rebuild.
Transmission Temp: Good to keep an eye on, as the stock gauge in the dash is an idiot light at best. Normal 150-190*, Towing 195-210*, Alarm 220*.
