Loosen 4 10mm bolts with deep socket on water pump housing and let coolant drain

After coolant drains, remove 4 10mm bolts from water pump housing and remove housing.

Place special Water Pump removal tool on water pump cartridge and using ½" drive breaker bar turn clockwise until pump slips off housing.

Remove pump and remove o-ring inside the water pump housing

Clean area good with cloth rag or paper towel

Put clear grease on new o-ring and install in water pump housing

Install new water pump and using special tool and ½" breaker bar turn counter clockwise until new pump snaps into place

Remove old seal from water pump housing cover

Put clear grease on new seal and install in water pump housing cover making sure to insert the fitting inside the bypass hose by the thermostat
