To replace the pulley on the power steering pump of a 1995 Ford Aerostar, first, remove the serpentine belt and disconnect the power steering pump from its mounting. Use a pulley puller to carefully remove the old pulley from the pump shaft. Once the old pulley is off, position the new pulley on the shaft and use a pulley installer tool to press it onto the pump evenly. Finally, reattach the power steering pump and reinstall the serpentine belt.
