How to Replace the Power Steering Pump in a LeSabre

Without the power steering pump working on your Buick LeSabre, you are going to have a difficult time steering. To replace the power steering pump, you are going to have to remove a pulley that is connected to the power steering pump. The power steering pump is on the driver side of the engine compartment, and a plastic reservoir is connected to the top of the pump containing the power steering pump fluid.

Remove the nut that is connecting the pulley to the engine and power steering pump using the wrench. Place the drain container below the power steering pump reservoir. Remove the nut on the hose that is connected to the power steering pump and allow the fluid to drain.

Remove the power steering pump reservoir by unhooking the clips on the right and left side of the reservoir. Remove the bolts that are mounting the power steering pump to the engine using the wrench. Pull the power steering pump off the engine.

Mount the new power steering pump onto the engine and tighten the bolts using the wrench. Reconnect the power steering pump reservoir to the top of the power steering pump. Reconnect the power steering pump hose and tighten the nut using the pliers. Replace the pulley to the engine and fill the power steering pump up with power steering pump fluid.
