On the passenger side look under the dash. You will see a black cover with 7/32 screws(3). That houses the blower motor. Turn the blower on high....you can feel the vibration when you hold the cover
The thermostat on a 1995 Saturn SL1 is located on top of the motor. The largest hose coming off the radiator will have to be loosened to access the thermostat housing on the motor.

The starter on a 2001 Saturn SL1 is located on the driver's side of the engine. It is just to the left and in front of the alternator/generator.
What kind of vehicle?
Buy a car that isn't a Saturn
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!
In the tank.
12.8 Us gallons
On the 1995 Saturn SL1 The oil pressure sending unit is the sensor closest to the alternator. The unit is on the back of the block.
