I've a issue since a month, my temperature gage is already at warm position in the morning when I start my truck. I've change my lower radiator hose last week and refill and purge de system and still same problem with the temperature gage.

Any idea ?

 

Sounds like a sensor issue. Which engine is it?

Do you have access to an inexpensive code scanner that reads PIDs?

 

5.4l. I have an OBDII reader, but not a full scanner. Also, it look lile I still havr air in the system, my hot air is more like warm.
