How To Remove a Water Pump in a 1992 Ford F-150
by Kyle McBrideThe water pump on a 1992 Ford F-150 light duty truck is mounted on the front of the engine behind the radiator. You will hear a bearing noise during engine idling if the bearing in the water pump is bad. Leaking coolant from the area around the front pump seal or coolant seepage from the pump's drain hole indicates that the water pump requires replacement. Allow the engine to cool completely before you begin to remove the water pump. Coolant temperatures inside the engine are hot enough to severely scald you when the engine is at or near operating temperature.
Step 1
Position a drain pan under the radiator's drain plug on the F-150. Open the drain plug to drain the coolant.
Step 2
Remove the screws holding the radiator shroud to the radiator, using a socket and ratchet or a screwdriver. Remove the shroud and set it aside.
Step 3
Remove four screws holding the fan clutch to the water pump, using the socket and ratchet. Pull the fan clutch assembly off the water pump, then set it aside. Take care when removing the fan clutch not to hit the radiator.
Step 4
Remove tension on the accessory drive belt by loosening the auto-tensioner idle wheel retaining bolt with a socket and breaker bar. Slip the belt off the water pump pulley.
Step 5
Remove bolts holding the air-conditioning compressor/power steering pump bracket to the front of the engine, using the socket and ratchet, if your engine has these accessories. Move the bracket and the attached accessories aside to gain access to the water pump.
Step 6
Loosen the hose clamps on the hoses connected to the water pump, using a screwdriver or pliers, depending on the type of hose clamps on your F-150. Grasp each hose firmly, twist to break the seal, then pull the hose off the water pump.
Step 7
Remove the bolts holding the water pump to the front of the engine, using a socket and ratchet. Note which bolts are removed from which holes. Remove the water pump.

Tips
- With a 5.0-liter or 5.8-liter engine with super cool and air-conditioning options, the fan clutch is threaded. Removal of the fan clutch in Step 3 requires special tools--Ford No. T84T-6312-C and T84T-6312-D. These tools are a fan clutch pulley holding tool and a fan clutch nut wrench. Hold the pulley with the pulley holding tool, then turn the large clutch nut counterclockwise with the clutch nut wrench.
- Pay special attention to the length of the bolts removed from the water pump in Step 7. The bolts will be different lengths, and you must reinstall them into the holes from which they were removed when you begin reassembly.
