How to Remove a Water Pump From a 94 Ford F150by John Stevens J.D.
The 1994 Ford F-150 is equipped with a mechanical belt-driven water pump. The pump operates not only to pump antifreeze through the engine, but also to push the antifreeze from the engine into the radiator. Within the tip of the water pump is a single bearing, which is pressed into place at the factory. The majority of water pump problems can be traced to this bearing. If the bearing is damaged, the pump will leak and need to be removed from the engine.
Drain the cooling system by removing the draincock fitting at the bottom of the radiator with a wrench.
Squeeze the two tips of the hose clamp on the end of the lower radiator hose with a pair of channel-lock pliers and pull the hose off of the bottom of the water pump.
Remove the bolts which secure the fan shroud to the engine-side of the radiator with a wrench, then push the fan shroud over the fan blades.
Insert the tip of a 1/2-inch breaker bar into the center of the tensioner pulley, then push the breaker bar in a clockwise direction to release the tension on the drive belt and pull the belt off of the water pump pulley.
Remove the fan blade assembly from the tip of the water pump with a clutch fan removal kit to access the water pump pulley’s four securing bolts. Not all clutch fan removal kits are used the same way, so consult the kit’s user instructions.
Remove the four bolts which secure the water pump pulley to the front of the water pump with a wrench.
Remove the single bolt which secures the alternator’s pivot arm to the front of the water pump with a wrench.
Squeeze the two tips of the hose clamp on the end of the heater hose with a pair of channel-lock pliers and pull the hose off of the top of the water pump.
Remove the water pump’s securing bolts with a wrench and pull the water pump off of the engine block. If the pump is stuck, dislodge it by striking the side of the pump with a rubber mallet.
