The starter on your saturn is located on the rear side of the engine. This is best accessible from the bottom of the car up. Here is an illustration of the location.
Caution: Ensure that the vehicle is properly supported and squarely positioned. To help avoid personal injury when a vehicle is on a hoist, provide additional support for the vehicle on the opposite end from which the components are being removed.
Notice: Always spray the starter solenoid electrical connections with penetrating oil prior to removing the nuts. Use extreme care to prevent cracking the solenoid end-cap, which will allow moisture to corrode the solenoid contacts.
