Operating range of fan

Low Idle=533
HI Idle=488
Operating range of fan=0-4000

Motor at standard temp. operating range

High idle is 2500 for this. (not high idle mod)

Most likely the oil temp sensor wiring pigtail. If it is open or shorted it could cause the fan clutch to lock on because it thinks oil temp is off the chart.

Well the truck sounds like a helicopter all the time. The fan sounds like the truck is hot after pulling long hard grade with heavy load all the time. The oil and coolant temp show good on AE . Its not running any different just loud wuth fan.

If the fan is "on" all the time then it may be a oil temp sensor problem.
