Did you put the thermostat back in? Did you run the truck up to
operating temp then check the coolant level in the radiator... should
be a couple inches below the cap or top...refill if found lower...
Did you check the fan belt tension?... At operating temp with
thermostat installed the water should be circulating (look in fill
cap)... Note : when replacing the radiator, after you fill with
coolant, you can run the engine without the cap on the radiator while
warming it up so you don't have to pull the cap while system is under
pressure...If there is no flow at temp. the waterpump could be
shot...Or a collapsed bottom hose could be happening... to check
this out rev the engine while looking at the bottom hose and see if
it flattens in the midsection when revving... Spring inside may be
gone. Did you put the fan shroud back on??/ Did it have one?
