Saturns do not have frost plugs....If you are looking for a place to put a block heater the only one you can use is an external heater.....only 50$ish from Saturn
yes
no. mine does not have power steering and it's a 1999 sl1
The speed sensor on a 1999 Saturn SL1 is under the transmission. It is below the fittings for the transmission cooler lines.
no
My son's 1999 Salvaged/total Saturn SL1 was rebuilt using many engine and body parts from 1995-1999 Saturn SL1 and SL2 cars, I believe it will work fine. I do not recommend before 1995 or 2000 or later models. I do not recommend SL2 either. I am not the expert but most of my son's engine is not 1999 SL1. Good luck!

The starter for a 1999 Saturn is on top of the transmission under the air filter box. Remove the filter box for easy access.
