READ these instructions completely before you begin.

Step 1

Get the correct water pump and, if necessary, a clutch fan for your vehicle. Also get a water pump gasket, some gasket sealer and antifreeze. Check with your local NAPA Auto Parts store for the specific parts you need.
Gather together all the necessary tools.
Let the engine cool.
Disconnect the battery ground.
Drain the cooling system. Follow the precautions in NAPA's Maintaining Your Cooling System "Do-It-Yourself Guide".
Step 2
Loosen the alternator and other accessories at the adjusting brackets and remove the drive belts.
Remove the fan, pulley and radiator shroud (if so equipped). If you're removing the fluid fan drive, set it aside with the flange UP to prevent fluid from draining into the bearings.
Remove any brackets or accessories that interfere with removal of the water pump.
Remove all hoses attached to the water pump.
Remove the retaining bolts and then the water pump.
Clean the mounting surface on the engine.
Step 3
Install a new gasket and gasket sealer between the water pump and the engine mounting service, and install the pump.
Reconnect all hoses to the water pump, and replace any brackets or accessories removed previously.
Replace the fan, pulley, radiator shroud (if so equipped) and drive belts.
Adjust all belts to the proper tension, and fill the system with a 50/50 antifreeze/water mixture.
Reconnect the battery ground cable, start the vehicle and check for leaks.
