Review on ACDelco Professional 252-962 Engine Water Pump: Superior Performance and Durability for Efficient Engine Cooling by Paul Weakland

The original ACDelco water pump lasted 130,000 miles so I hope this one will last as well. Supplied with spare bolts, torque to specification. Do not reuse old screws. Also comes with a new felt pad which was originally just a rubber silicone ball. If you buy for the enclave as well, it will take around 4 hours to install. Please note that you can replace completely from below. Remove the front passenger wheel, inner fender liner, loosen the water pump pulley bolts before releasing the tension on the poly V-belt. Then remove the 6 water pump bolts. You can pull out the old part through the bottom and flip it over. These are tight spaces and all you can use is a 1/4" ratchet and 10mm socket to get the job done. the new seal is aligned Reverse the installation procedure.
