It sounds like you have air in the Cooling system and the bars leak permanent seal does not help. The sealer creates restrictions through out the water jackets and can cause the thermostat to stick. Replace the radiator cap and run the truck with the radiator cap on the first click and keep an eye on the over flow tank, refill the over flow as needed and make sure you have the heater on the highest setting to work out all the air in the system. Once all the air has worked it's way out of the system, then you can close the radiator cap to the second click to ensure full pressure is built up in your cooling system. Good luck and keep me posted.
