The other day all of a sudden my temp light came on! I turned off the truck and turned it back on and the light and the temp gauge was back to normal...so what can cause this problem because it is at the dealership now and they have no clue
my wife was driving the truck and she said the light came on. I asked her did the needle got to the H and she said it did. She was in the parking lot and she drove it"yea I know" and she said the light went out. I took it to the dealership yesterday and they ran it for codes and did not find anything. I told them just to let it run and it will probably coemback on but they didn't do it.
