A list if things to check, fan clutch, radiator shroud, water pump may not circulate, clogged passages in engine or hoses. How hot does it get?

Did you burp the coolant system and add coolant? Are you sure you got all the air out of the system?

Park the truck with the front up hill & fill while the engine is running, allowing the system to burp itself. That's the only way to ensure you get all the air out.
