I think first make sure it is overheating by placing an appropriate thermometer in the radiator tank.
You can get an infrared thermometer from Harbor Freight for around $30.00, but I'm always suspicious of them.
Replacing the thermostat will not solve the problem.
The cooling systems on these trucks was designed to work in slow speed and stationary situations. If you have an overheating problem, something is really wrong.
