If your water pump is leaking, then it will have to be replaced. This is not a job for the beginner as you will have to rmove the timing chain cover, harmonic balancer and timing chain. If you tackle this job your self make sure you mark your valve gears, crank and replace the chain exactly the way you removed it or your timing will be off.

Lift th car using a jack. Support the Oldsmobile Alero with jack stands and the engine using a lift or some other engine support device.
Drain the Oldsmobile Alero's colling system by opening the cap on top of the radiator and unplugging the drain plug underneath the radiator. Position a large container under the drain hole to catch the draining coolant.
Disconnect the components that lead to the water pump with an adjustable wrench Lay them out in the order removed. In order, these parts include the automatic transaxle (if equipped), front wheel on the right side, splash shield, water pump sprocket and the access plate to the timing cover.
Use the access plate bolts to secure the water pump sprocket holding tool to the engine cover. Remove the pump bolts, front cover, thermostat housing, water pump feed pipe and two engine bolts using the adjustable wrench. Lift off the water pump.
Remove the bolts that secure the water pump to the block. Take off or scrape away the gasket. Remove and discard the o-ring between the water pump inlet pipe and the pump.
Spread a small amount of sealant on the water pump, on the areas where it mounts to the engine. Place the gasket on the sealant. Position the water pump onto the engine.
Insert the new bolts into the water pump. Torque the bolts to 89 inch pounds torque. Reconnect the other components in the order removed using an adjustable wrench.
Re-insert the drain plug into the radiator. Remove the engine support and jack stands. Lower the Olsmobile Alero to the floor.
Refill the radiator with coolant according to the instructions in your owner's manual. Screw on the radiator cap. Attach the negative battery cable to the post. Close the hood and test the car.
