Bolt sz of starter '02 L2 saturn

12 and 14 ml.Socket,s --disconnect battery ,undo the wires to starter.remove bolts.

The Starter is located under the intake manifold on th back bottom side of the motor!
The only way to remove it is from under the car!
Remove the Neg Battery terminal from the battery before going under the car.
If I recall correctly, there are (2) 14 or 15mm bolts holding it to the engine block, one of them is a Blind bolt, as you will only be able to feel its location on the back side of the starter. (tip, when replacing the bolt behind the starter, either have a small magnet inside the socket to hold the bolt inside the socket while tring to locate the hole. You could also use a small piece of paper or plastic bag to wedge the bolt head to the socket so it doesn't fall out while tring to locate the hole!
You will also have a 13mm nut holding the Positive battery and Alt. cable to the starter and a 10mm nut holding the wire coming from the ignition switch.
Hope this helps!
Happy Saturn Motoring!

All of the nuts and bolts are metric on it. It helps to use a 13mm swivel socket on the starter bolts but you can use a wrench if you need to. Also, a 7/8 open end wrench for the 02 sensor, or an 02 sensor socket.

Let me give you the steps for the starter and also the front engine mount bracket. You don't have to remove the entire mount, just the bracket

REMOVAL

1. Open Hood.
2. Disconnect the negative battery cable.
3. Raise vehicle and support.
4. Disconnect the electrical connector from the 02 sensor.

Remove the 02 sensor from the exhaust manifold .

Remove the front mount through bolt.

Remove the front mount bracket from engine block.

Remove the battery cable from starter.

1. Remove the lower starter bolt and remove starter.

INSTALLATION

1. Install starter to transmission.
2. Start the upper starter bolt.
3. Start the lower bolt and snug it so that the starter will not move.
4. Remove the upper bolt.
5. Connect the battery cable and torque nut to 8.5 Nm (75 in. lbs.).
6. Install the front mount bracket and check heat shield location.
7. Install bolt the upper bolt and torque bolt to 54 Nm (40 ft. lbs.)
8. Install the lower and torque bolt to 54 Nm (40 ft. lbs.)
9. Install the front mount through bolt and torque bolt to 61 Nm (45 ft.. lbs.)
10. Install the 02 sensor and torque to 27 Nm (20 ft. lbs.)
11. Lower vehicle.
12. Connect the negative battery cable.

FRONT MOUNT

REMOVAL

2. Loosen the rear mount through bolt.
3. Remove front mount vertical bolts (Fig. 87).
4. Remove front mount and separate the starter heat shield.

INSTALLATION

1. Position front mount on lower radiator crossmember.
2. Loose install front mount to bracket through bolt.
3. Install front mount vertical bolts. Tighten bolts to 61 Nm (45 ft. lbs.) . (Fig. 87).NOTE: Be sure the weight of the engine is static and in rest position. this for a 2.7 v6

Hello, Disconnect the negative battery cable with a wrench. (2)Lift the front of your Saturn with a floor jack. Position two jack stands under the front end and lower the vehicle onto them(3)Find the starter at the rear of the engine where it couples with the transmission. It is a cylindrical component about 7 inches in length and 4 inches in diameter. The starter solenoid, a smaller cylindrical component, mounts on top of the starter. Pull off the pin holding the shield to the starter solenoid with a pair of slip-joint pliers and remove the shield.(4)Spray the electrical and cable connections at the back of the starter solenoid with penetrating oil. This will help the retaining nuts release easier.(5)Unfasten the retaining nuts securing the battery cable and electrical connectors to the back of the starter solenoid using a wrench.Put on your safety goggles and crawl under your Saturn. Unfasten the lower starter mounting bolt with a ratchet, short ratchet extension and socket. Remove the upper starter mounting bolt with an obstruction wrench. If you cannot reach the upper bolt from underneath, try reaching the bolt through the opening on the intake manifold support bracket.6)Unfasten the bolt holding the rear starter bracket to the engine using a wrench, if your starter has this bracket (not all 1993 Saturns do)(7)Remove the starter from the engine compartment.
Thanks

special tools needed ,one to go through the bolt hole in front of engine block right hand side ,remove bolt and then screw special bolt/locating pin in ,common rail doesnt need timiing in as its only a pump ,cam is located by aligning sensor with lug on cam .This is not a do it yourself job special tools needed to lock the crank into position after removing starter motor as well also crank pulley is on a taper and the cam .better off taking it to a dealer

Starters are generally held in place with two large bolts and possible a secondary bracket. There will be a cable on a large bolt for the battery and maybe a smaller wire for the solenoid that engages the starter. A Good set of sockets with a few extensions and a small pair of pliers open end wrenches will get you through the job with no trouble. Good luck.

you have to use an extension for the upper bolt

Look at rotation of harmonic balencer to remove bolt is in opposite direction.To remove bolt :Disconnect coil wire or wires so car will not start Next put socket on bolt with breaker bar and wedge bar some where solid on car. Bump motor with starter the small r turning of the starter will loosen bolt

Top bolt is almost dirrectly above bottom bolt but,toward engine about 1 inch. slip 13mm.socket with enstention behind starter solenoid ,you have to fish for this bolt.Very hard if you do not have a rack,We always remove it from bottom.

no there is not a special tool need more info go to collisionrepairadvice.com for more
