battery replacement is quite easy. you will need the following tools: 1/4 inch rachet
8mm socket
10mm socket
13mm socket
latex gloves (optional) First open the hood and locate your battery. begin by removing the battery connections with the 8mm socket. Usual order is remove the black (ground) connection first, then the red (positive) connection. using your 10mm socket, locate the nut on the top portion of the hold down bar. remove the nut and set aside. At the point of where the hold down bar meets the body furthest on the driver side, there is a bolt holding it to the body. this is also 10mm, remove this as well. Follow the hold down bar down the left side of the battery. way down at the base there is a 13mm bolt. remove the bolt. the hold down bar should now be loose, you can pull the bar out of the way. use latex gloves to protect you from any acid corrosion that you may come in contact with. grab your battery and lift strait up. if your battery has a black plastic cover on it, while the battery is out of the vehicle remove the cover and use on your new battery. installation is opposit of removal. when connecting the battery cables back to the battery, connect the positive first, then the negative. Be sure to remove the keys from the vehicle, or roll down a window and the locks may lock once power is reconnected.
I am prettysure you can change the motor as long as the body structure is the same and you have skill in this sort of thing.

How do I replace the water pump in my 1994 Saturn SL2 series standard twin cam.
yes
Disconnect the battery for about 20 seconds.
The Saturn sl2 does not have a timing belt, it has a timing chain. And under most conditions it does not need replacing.
There is not any adjustments to be made on alternators.

The 4 cylinder Saturn's all had timing chains.
