2016 V-10 E450 STRIPPED CHASSIS COOLANT TEMP
Hi.
I have a 2016 E450 stripped chassis with the V-10 in a Thor RV. The coolant temp gauge in the cluster is always steady and centered. I added a Scangauge ODB2 to monitor more data. The coolant temperature on the Scangauge typically shows 199-208 degrees. Sometimes I get higher reading. Does anyone know if this sounds like normal readings and what temperature reading on the Scangauge should I be alarmed? I've never had any indication of overheating, although the Scangauge read 230 one time. I've also never had a vehicle that showed temps over 200 so I just wanted to make sure this all sounds ok. Also curious what temp t-stat is installed and where the coolant sensor for the ODB2 is located compared to the coolant sensor for the cluster gauge?
thanks in advanced, John
I Hope this is the correct place to post

Hotshot
The temp "gauge" is basically a mechanical idiot light that is supposed to only have display positions - cold, normal, and hot. It does not display a linear response to engine temperature as would a traditional analog gauge.
This excerpt from the service manual defines the ranges.
This additional excerpt may be useful.
This excerpt from the service manual defines the ranges.
- NOTE: The coolant temperature should range between 0-59°C (32-138°F) with the gauge in the cold (C) range, between 60-120°C (140-248°F) with the gauge in the normal or mid-range and above 123°C (253°F) with the gauge in the hot (H) range.
Pinpoint Test D: Incorrect Temperature Gauge Indication
If the engine coolant temperature data is missing or invalid for 5 seconds or less or if the IPC receives invalid engine coolant temperature data for 5 seconds or less, the IPC defaults the temperature gauge to the last setting, based upon the last known good temperature status message received.
If the IPC does not receive the engine coolant temperature status message from the PCM for more than 5 seconds, the IPC sets DTC U0100:00 in continuous memory and defaults the temperature gauge to cold (C).
If the engine coolant temperature data is deemed invalid by the IPC for 5 seconds or more, the IPC sets DTC U0401:86 and defaults the temperature gauge to cold (C).
NOTE: If DTC U0100:00 is set in the IPC , other observable symptoms may be an inoperative tachometer, speedometer or odometer.
Normal Operation
The PCM uses the Cylinder Head Temperature (CHT) sensor to measure the engine coolant temperature. The Instrument Panel Cluster (IPC) receives the engine coolant temperature data from the PCM over the High Speed Controller Area Network (HS-CAN) communication bus. The IPC monitors the engine coolant temperature data received from the PCM and commands the temperature gauge indication with a corresponding movement of the pointer.If the engine coolant temperature data is missing or invalid for 5 seconds or less or if the IPC receives invalid engine coolant temperature data for 5 seconds or less, the IPC defaults the temperature gauge to the last setting, based upon the last known good temperature status message received.

Hi.
I have a 2016 E450 stripped chassis with the V-10 in a Thor RV. The coolant temp gauge in the cluster is always steady and centered. I added a Scangauge ODB2 to monitor more data. The coolant temperature on the Scangauge typically shows 199-208 degrees. Sometimes I get higher reading. Does anyone know if this sounds like normal readings and what temperature reading on the Scangauge should I be alarmed? I've never had any indication of overheating, although the Scangauge read 230 one time. I've also never had a vehicle that showed temps over 200 so I just wanted to make sure this all sounds ok. Also curious what temp t-stat is installed and where the coolant sensor for the ODB2 is located compared to the coolant sensor for the cluster gauge?
