Engine coolant temperature switch/sensor
The sensor is threaded into the coolant passage in the back of the cylinder head.
The engine coolant temperature sensor has nothing to do with the low coolant light. The low coolant sensor is mounted in the bottom of the overflow/filling reservoir by your washer fluid bottle. You will need to verify that the coolant overflow/fill bottle has coolant in it and if it does then the sensor is bad and will have to be replaced.

Fill your coolant to the level that it should be at. If it still comes on when the coolant is at its proper area, then it is an improper sensor. You will need to have it replaced immediately to reset the sensor.
Start by replacing the Engine Coolant Temperature Sensor
The guage on the dash uses the ONE wire sensor... This is located in the block near the drivers side. Eric First check to see if you have coolant in the radiator. If there is no coolant you will not get any reading from the temperature sensor. If there is coolant then change the temperature sensor.

bad fan or bad fan relay
Common for a cracked coolant temperature sender. Although there are many other possiblilites. Don't wait, get it figured out ASAP.
Hi this happened to me car. I had engine hesitation, high idle, stalling, temp gauge didn't work and the fan didn't turn on. I did a visual inspection and saw it had a crack in it. I replaced it and everything went away.
The light you are describing indicates low coolant level in the coolant reservoir.
Sounds like your cooling fan relay is shot. Ron J.
The computer with input from the engine coolant temperature sensor.
There is a symbol and light for temperature but, there is no symbol for low coolant. You need to raise the hood and take a look at the coolant recovery tank. That will tell you if it is low or not.
The reason the coolant light is on in a Saturn vehicle likely indicates a low level of coolant. Filling the receptacle should fix the issue.

Faulty coolant temp sensor can cause the vehicle to run poorly, if run at all. If you are leaning toward replacing the sensor you will be happy to know the sensor is relatively cheap, around $12, and simple to replace. Please visit my Bio for a link to my saturn help site for image of where the coolant temperature sensor is located.
7 quarts of coolant will fill your sl2
A 1995 Saturn SL2 will hold 7 quarts of coolant. Saturn vehicles are no longer made but can still be serviced by GMC dealerships.
You probably have a bad coolant temperature switch, this are fairly cheap and easy to install.
under the backseat and you just pull it out and put a new one right back in
Follow the radiator hose to the block on the drivers side. It will be clamped to a hose connection where the t-stat is. Right next to that connection on the right is the PCM coolant temp sensor.
Replace the engine coolant temperature sensor. Your car has two, replace the one with the 2 wire connector
