This is baffling. My truck has never had any problems. Now the temperature gauge seems to be out of whack. From cold start, it takes about 5 minutes for the temp needle to move which is normal. Once the truck is moving, the needle will not go beyond the center temp gauge. Now, without even moving, the needle will go beyond the red zone of the gauge in less than 5 minutes after the warming up phase. Why is this happening?

Hi there,

If the engine is not over heating i would replace the sender unit.
