To remove the power steering pulley from a 1998 Buick LeSabre, first, disconnect the negative battery cable and remove the drive belt from the pulley. Use a pulley puller tool to carefully extract the pulley from the power steering pump shaft, ensuring you follow the tool's instructions for proper use. Once the pulley is removed, inspect the pump and pulley for any signs of wear before reinstalling or replacing them as necessary. Remember to reattach the drive belt and reconnect the battery once the job is complete.
Put the belt tensioner tool on the tensioner pulley, and push away from you. Then you can slide the belt off. You either need to cut it or unbolt the engine from its mount and slip it out.
by hand
Well if it looks anything like my Skylark, then that motor mount has to come out. Make sure you support the engine with a jack and block of wood when you pull it. I just changed mine on my LeSabre yesterday and that is exactly how I did it. I also removed the right passenger tire for easier access to the motor mount.
the LeSabre has a timing CHAIN. It does not need to be replaced. (unless you broke it :)

All you need is a 3/8" drive ratchet to take the tension off the spring loaded pulley that tensions the belt. Remove old belt and put new one on, it is a little awkward because one hand needs to hold the wrench and the other hand slips the belt over the tensioning pulley but it is easy. Takes 5-10 minutes.
