To bleed air from the cooling system, take off the radiator cap and let the engine run. IF there is no radiator cap(some vehicle manufacturers have done away with them, just add coolant to the overflow tank to the correct level. The cooling system will purge air out on it's own

Park the truck so the front end is raised or jack it up, to get the radiator opening higher than the heater core. Then bleed the system normally by filling and running, heat on high, until thermostat opens. Then refill and top off.
There should be a radiator drain plug on the bottom corner of the radiator. (varies on which side) You'll probably have to remove some of the plastic skid plates on the bottom to get at it. Or if you want, just remove the lower radiator hose from the radiator and let it drain that way. To bleed a cooling system means to purge air out of it. Just take the radiator cap off and let it run for a short time. the excess air will come out.You may have to replace coolant .
Can be a defective temperature sending unit. If you just chance the coolant can be air trapped in the cooling system. You would need to bleed all air from the system. Can also be a defective gauge, but highly unlikely.
Replace the caliper and bleed the brake system.
