Disconnect the neg battery terminal at the battery. Remove the wires to the starter. Remove the two bolts that hold the starter in place and the starter will come out. Reverse the sequence to replace it.

Note that this is specifically for a 1995 E320.

1. Disconnect battery.
2. Raise front of car and support safely.
3. Remove air box cover. Failing to do this may cause damage when the engine is lifted.
4. Remove bottom splash cover under engine.
5. Remove bottom bolts from left and right engine mounts. One each.
6. Remove top bolt from right hand engine mount. This is perhaps the most difficult part of the job. It is accessed from under the car, using a 16mm box wrench or a flex head ratchet and 16mm socket. If you only have the box wrench it is a slow go but will work. A flex head ratcheting box wrench might be perfect but I didn't have one to try. 5/8" is very close to 16mm if you have that it will work. It might be necessary/helpful to jump to step 8 and take the weight off the engine mount to more easily remove this bolt.
7. Remove the heat shield from the engine mount. It just sits on top of the engine mount bracket and will be loose when you take out the bolt in the previous step.
8. Jack up the engine enough to remove the engine mount. I used a piece of 2x4 between the oil pan and the jack.
9. Remove the 4 bolts holding the engine mount bracket to the engine block and remove the bracket.
10. Remove the battery cable and starter solenoid wire from the starter.
11. Remove the two bolts holding the starter to the bell housing.
12. Remove the starter.
13. Reverse steps to install new starter.

NOTE: It is helpful to install the top right and bottom left and right bolts of the engine mounts loosely to get everything lined up then lower the engine down and tighten them fully. Note that the engine mount has a tab that lines up with a notch in the engine mount bracket. There is only one correct way to install the engine mount.
I recommend using a high-quality replacement starter motor and solenoid. Replacement with an OEM starter can reduce the risk of another replacement later on. https://www.hexautoparts.com/new-starter-for-1998-1999-2000-2001-2002-2003-mercedes-benz-e320-ml320-17757.html
