Eh i know this might seem a bit weird. but my truck barely goes over 140 degrees. and its got a 180 Thermostat. literally after drivin for 2 hours towing and idling at the job. i can touch the radiator and it will be ICE Cold. I then touch the hot water hose, and its cool to the touch, and grab the other and its even colder. any idea's?

 

was the thermostat replaced recently? could be stuck open.
