During the summer, driving uphills the truck tends to overheat. With a very light load ( 1 sheet of plywood), going uphill, tempature gauge will climb to about 240. When I stop and turn off the engine, you can hear the coolant bubbling. There's no leacks of any fluid anywhere. Thermostat was replaced about 4 years ago.Suggestions as to causes?
