How do you replace the water pump on a 1995 Ford F-150 4.9L I6?

Tools and Materials Needed

* New water pump

* Water pump gasket

* Thermostat and gasket

* Coolant

* Wrench set

* Socket set

* Screwdriver

* Pliers

* Funnel

* Rags

* Safety glasses

Instructions:

1. Drain the coolant. Place a drain pan under the radiator and open the drain plug. Allow the coolant to drain completely.

2. Remove the serpentine belt. Use a wrench to loosen the tensioner pulley and remove the belt.

3. Remove the thermostat housing. Use a screwdriver to remove the screws holding the thermostat housing in place. Lift off the housing and remove the thermostat. Discard the old thermostat and gasket.

4. Remove the water pump bolts. Use a wrench to loosen the bolts holding the water pump in place. Remove the bolts and lift off the water pump. Discard the old water pump and gasket.

5. Clean the water pump mounting surface. Use a scraper to clean the water pump mounting surface. Be sure to remove all traces of the old gasket.

6. Install the new water pump gasket. Place the new water pump gasket on the mounting surface. Be sure to align the gasket with the holes in the water pump.

7. Install the new water pump. Place the new water pump in position and install the bolts. Tighten the bolts in a crisscross pattern until they are snug.

8. Install the new thermostat and gasket. Place the new thermostat in the housing and install the new gasket. Be sure to align the gasket with the holes in the housing. Replace the housing and tighten the screws.

9. Reinstall the serpentine belt. Place the serpentine belt around the pulleys and use the tensioner pulley to tighten the belt.

10. Refill the coolant. Open the radiator cap and add coolant until the radiator is full. Start the engine and run it for a few minutes. Check for leaks and add coolant if necessary.

Tips:

* Be sure to use a quality water pump and gasket.

* Tighten the water pump bolts in a crisscross pattern until they are snug. Do not overtighten the bolts.

* When refilling the coolant, be sure to use a 50/50 mixture of coolant and water.

* Check for leaks after starting the engine.
