Ford F-150 5.4-Liter V8 Water Pump Replacement D.I.Y.
New Water Pump
The water pump in your F-150 pickup’s 5.4-liter V8 is held in by four bolts, all of which are buried behind the smooth pulley that carries the clutch fan. You have to remove that pulley to access the water pump bolts, but once all of those bolts have been removed, you can carefully wiggle the old unit out of the engine block, noting that the o-ring makes for a very snug fit.
You will re-use that pulley, so you will want to clean that piece up with some light grit sandpaper and set it aside, along with the bolts that held it in place. Also, while the water pump is out of the block, carefully wipe out the area where the pump pushes into the engine block.
Once everything is cleaned up, you can begin the installation of the new water pump in your F-150.
Inset the new pump in the block, bolt it into place and replace the pulley that carries the clutch fan. Once the water pump assembly is all tightened up, replace the serpentine belt followed by the clutch fan and the radiator shroud. Reconnect the upper radiator hose, replace the engine air intake and refill the coolant system and you are ready to fire up your F-150 and top off the coolant system.
