How to service the Water Pump on a 6.4L Diesel engine on 2008 Ford F-250 Super Duty?

The first step to service a 6.4L Diesel engine coolant pump requires draining its cooling system. Start by removing the engine cooling fan then unfasten the coolant pump pulley bolts. Through clockwise rotation of the accessory drive belt tensioner you can move the drive belt out of the way to detach the bolts and coolant pump pulley which should be fastened back to 31 Nm (23 lb-ft) torque values. You should remove the bolts and the coolant pump along with discarding the old O-ring seal. Use a torque wrench to fasten the bolts on the new coolant pump at 31 Nm (23 lb-ft) when installing it while also replacing the O-ring seal. To finish the process reverse all steps from removal.
