How old ?????????????????? If the thermostat is OK, someone has to check the burnt head gasket. . . . . . . . . . . . . . Do not forget to check the water pump and leaks. !!!!!!!. . . . Pump, thermostat, head gasket, in that order. . .

The problem is that you didn’t buy a Ford. Sell the hunk of junk and get the #1 truck in America. . . . . . . Ford.

Fill your vehicle’s water with the engine cold. Do not run your vehicle anymore until you have done this. If you only add water when it is warm (or hot) it is not filling up properly, and you may not have as much water in there as it is supposed to have. If this does not fix it, your water pump may not be working properly or at all. Make sure the belts are okay. If the problem persists, see your local mechanic, as this can lead to other serious problems.

You could have a clogged radiator hose or you may need a new water pump

Have you checked to make sure that a hose hasn’t collapsed. Sometimes when hoses get old they get weak and when the system is under pressure and heat they collapse. That would be where I start. If your hoses are fine then I would replace the thermostat, then go on to the water pump the impeller on the pump may be worn and not pumping the full amount. You could have a plug in the radiator or heat core as well.
