I bought the truck not even a year ago. Its got a brand new paint job, head gasket, water pump, slave cylinder, clutch master cylinder, and thermostat but I can't figure out why it's still overheating it might be the radiator but I done flushed it and all that I might need to buy a new one any help please

I suspect you need to replace the radiator, due to corrosion or mineral buildup. Afterwards, fill it with a 50/50 mixture of the proper antifreeze and distilled water.
