Change the coolant temperature sensor near the thermostat housing.
|
Just check out the temperature, or there would be some normal problem in your coolant.
|
Yes! Check if there something wrong with the coolant. Other than that there must be something wrong with the temperature
|
I think you should check your truck coolant.
