openair Posted July 27, 2016 at 02:06 PM Report Share Posted July 27, 2016 at 02:06 PM Does anyone know what temperature the first hash mark from the bottom on the engine temp gauge represents? It is normal the engine temp gauge would remain at this temp for nine hours after the engine last ran? Quote Link to comment Share on other sites More sharing options...
larryh Posted July 27, 2016 at 09:28 PM Report Share Posted July 27, 2016 at 09:28 PM The temperature gauge shows the temperature inside the heater core--not the engine block temperature. You can see the actual value of the temperature in the heater core using ET mode. Quote Link to comment Share on other sites More sharing options...
