How to service and repair a water pump on Buick LeSabre?

Begin your Water Pump work by disconnecting the negative battery terminal. Detach the coolant from the system and take off the Drive Belt. After disconnecting the Battery Cable and draining the coolant you need to remove all bolts from the Water Pump Pulley and its unit. Pull out the two Water Pump mounting bolts (1, 2) and simply take away the Water Pump. Prepare both parts before putting a new gasket and Water Pump back onto engine base. Fasten Water Pump bolts (1, 2) by torquing the short bolts to 15 nm (11 ft. Lbs.) and the long bolts to 30 nm (22 ft. Lbs.). Attach the Water Pump Pulley to its base and bolt it down with torque of 13 nm. Put on the Drive Belt then reconnect the battery and complete coolant service. Check for any coolant leakage.
