If you have a lot of pressure on your upper radiator, you have likely come across a thermostat issue. Did you put the wrong color of antifreeze in your truck? If you did, this is the problem, but I’d still suggest replacing the thermostat. If your hoses aren’t tight you may have a water pump problem, but this is less likely to be the issue. A certified YourMechanic technician can come to your location to inspect this issue with coolant and help you diagnose your vehicle.
