2006 international 4300 DT466 tree trimming boom truck. Truck runs hot when you're driving over 50mph. Will idle on the job all day long and not get over 200° if you slow down to 40 miles per hour or less temperature drops back to the 200°range. It has new thermostat new radiator hoses new water pump flush has been run through the engine twice and the external radiator itself has been cleaned. Any ideas possibly bad radiator?
