It depends on the year. For quite a while the points could be accessed through a little hole on the side of the distributor cap. The points were installed "close enough" to get the engine started then you would use a "dwell tach" to set the points through the little hole. But for the record, newer GM engines don't use points.
The "dwell tach" the previous poster is referring to is a combination tachometer and dwell meter that can be purchased at most auto parts stores. The points should be set for 30 degrees dwell. Most GM cars stopped using points and went to HEI around 1974.

How do you replace an ignition switch in a 1998 Saturn SL2?
Is should not be that difficult. Pickup a service manual, I believe that the Saturn uses GM's Passlock Anti-theft system. If you are having problems with the ignition or the car starting, it is more than likely thie ignition cylinder lock. This is a common problem with GM vehicles. This also should not be all that difficult to replace. There is a bit more to it than replaceing the ignition cylinder lock you will have to reprogram the system to read the new key unless you have the new lock keyed to match the original key.
