How do you change water pump on 6.0 ford diesel?

Answer 1

Disconnect the negative battery connections.

I began by draining the radiator by opening the valve at the bottom. Let this drain and move on to the next steps.

Disconnect the upper radiator hose that comes from the thermostat, the small hose that leads to the degas bottle, and the electric connection for the fan.

Carefully detach the plastic covers that are snapped in on top of the fan shroud.

Remove the two 8mm bolts that hold the front fan shroud to the radiator.

Get underneath the truck and disconnect the lower radiator hose slowly to minimize getting the rest of the coolant all over the place.

Disconnect the two transmission cooling lines that are attached to the bottom of the radiator.

Back on top of the radiator the two mounting brackets are removed by loosening the four 8mm bolts.

You now can pull the radiator forward allowing room to slowly pull the front fan shroud upward and out of the truck.

Follow this by slowly lifting up on the radiator and remove it from the truck. I did this to allow more working room.

At this point, the fan assembly needs to be removed to access the water pump.

Unclip the fan wire harness from the rear fan shroud.

The rear fan shroud is attached to the engine with four 15mm bolts. Two at the top and two at the bottom. Access was easy between fan blades with ratchet extensions.

Now pull the rear fan shroud forward to expose the fan clutch nut.

I used a long screwdriver placed in the holes of the water pump pulley cover to keep it from moving. Instead of the expensive fan wrenches or removal tools, I used an 18" pipe wrench ($15 at tool store) on the nut, turning it counterclockwise.

Upon loosening the nut the entire way, you can now carefully remove the fan and the rear shroud all at the same time up and out of the truck.

The water pulley cover is attached by four 10mm bolts. Loosen the bolts and then release tension on the serpentine belt by using 1/2" drive ratchet clockwise in the tension pulley located to the left of the water pump.

Pull the belt out of the way and finish removing the pulley cover and plate.

The water pump is now exposed. Remove the four 10mm bolts that attach the pump to the front cover. A slight tap popped the water pump off of the engine.
