power steering fluid

Any DoT 3 PS fluid should work, 2001/2002 started using ATF+4, but you should still be PS fluid. Any store will carry what you need. Be sure to match what you have, don't switch over to ATF4 because ATF4 and PS fluid don't mix. If you did want to switch over to ATF4 you'll have to flush the entire system.
