How to check and replace Cooling Fan and fan clutch on Ford F-250?

To inspect fan clutch in vehicles, cold start the engine and turn the fan manually to ensure it rotates smoothly. Construct a flat box with an open center through which the fan clutch can fit, start the engine, and listen for that first "roar" when the running fan kicks in. The sound should die away within five minutes. Place the flat box in front of the radiator, start the engine, and keep it above 2,500 rpm while checking on fan engagement as well as engine temperature. If it reaches the highest safe temperature without engaging the clutch, replace it. Start the engine after removing the board and raise its speed above 2,500 rpm to study the slowing down of funs. Replace the fan clutch if it does not disengage even after five minutes. For the removal of bolt-on fan clutches and their installation, take off the radiator shroud, unscrew the clutch from the water pump, and pull out the whole assembly. Reinstallation is a reverse procedure.
