Check to see if your coolant is dark. If so, then you may be leaking oil from the engine due to faulty head gaskets. You might get this fixed at GM's expense. I found the following web site that may be helpful:

I just changed the engine in my daughters SC2. The First one had 133K and she did not watch the oil. The new one has 48K. Runs good, but is still using lots of oil. My research shows this is an on going problem.

I also have a problem with my 94 SC 2 over heating. The only solution I have come up with is running the heater on high. It cools the temp, but it is not the best solution considering the summer heat. I also have difficulty shifting gears. Sometimes it gets so bad that I have to shut off the car to get it into first. Does anyone have any solutions to this. No one seems to know why it does this.

I have a 93 sc1, 114,000 miles. my temp gage goes way up at idle, and strangely enough, I turn on the AC and the temp goes down, so that's my solution. Tranny blew at 72,000, alternator at 50,000. Now the mystery oil consumption (as much as a quart every 200 miles) is getting bad, ton's of blue smoke the first ten minutes after starting.

I could not sick through a drive through without my temp gauge going to red. Oil just disappeared. No leak- just burned oil. (94 SC 2)

I also own a 94 SC2. If you do not have the air deflector underneath the car, it will cause overheating problems. I suggest finding one at a junkyard. You can spend all kinds of money on parts, but the deflector is probably going to solve your problem. If you don't like your temp gauge going past half way, then you can turn on your A/C; the fan will automatically come on.

I had the same problem with my 1994 SC2 after driving through some high water. I replaced the air director, but instead of using the plastic mounting blocks we used heavy duty zip ties (saving $80). That has been about 1 1/2 ago now and I have not had any problems with it coming off.

I too have the same overheating problems. I have replaced everything. I have wired the fan direct. This does not remedy the problem. I am missing the air dam, so I suppose that I do not get the airflow required. On short trips I'm fine. Longer highway speeds and it heats up. I am going to experiment with it. As far as the oil consumption, mine also did this until I took the advice of a friend who was having the similar problem in another vehicle. I was not loosing or using oil, it was just disappearing. I now use Castrol High Mileage 20w50, with no oil loss. In regards to the transmission and gear engaging, the master cylinder and slave cylinder are hydraulic and very touchy. If you do not have every little speck of air out of the lines, it will not work correctly. Some people will say no to this, but I removed both from the car and bench bled them. I also recently replaced the clutch, pressure plate and release bearing. Not as hard as expected, but you have to pull the motor and transmission . This car is a great running car and is fun to drive. I'm 6'-3" so I have to shoehorn myself in. I just wish I could solve the heat problem. I'll get back when I figure it out.

I am the owner of a '94 Saturn Sc2, and I have had many problems with this car. Granted, it has 213,000 miles, my problems begun a long time ago. I had to replace the clutch twice, once at 200,000, and again a thousand miles ago due to the engine mounts. It is so hard to find parts for this car, and installing them is even harder. I have many mysterious problems with it, such as the temperature, alignment, and exhaust. I would not recommend this car to anyone. I got it for free, and it has cost me 2,500$ so far. This car is not made for speeds above 45 mph.

Wow a lot of people that don't seem to get it. The air dam on your Saturn is how your radiator gets its air flow. The grille on the older Saturns are for looks only. If you don't have the air damn you get almost no flow to the radiator. No air flow to radiator means no cooling of the coolant. Put the air damn back on. 20w50 oil. Ouch talk about a way to kill a engine. Ya think that they recommend 5w30 for a reason. Hmm Well anyways I have a 94 sc2 with 135,000 and it's a great runner, but then I take care of my cars. Would recommend Saturn to anyone that wants good gas mileage and a sporty look, but I admit it does kinda suck in the snow.

If your saturn is getting hot, the temp. sensor on the engine may be bad, it tells the computer in the car when to turn the fan on.

I have a 94 Saturn SC2. I got it from my daughter. It had a bad idle problem, fluctuated from 1600 to 800 rpm and back. The car was hard to start. Sometimes I had to hold the gas pedal to the floor to start it. Someone suggested I replace the coolant temperature sensor that reports to the cars computer (NOT the one for the gauge). It fixed my idle problem and the car starts every time now. I was astonished at how much difference that $20 part made to this car. Be sure to get the part from Saturn. Make sure it has the brass tip.

I bought a 94 SL2 about 2 months ago for fairly cheap.
The only thing wrong with it at the time was the seal between the roof and the door would leak. I fixed that, and the over heating issue that so many others have, has arisen.
Temp sensor, thermostat, radiator, and deflector have all been replaced, and there is still that persisting problem.
I do fine at speeds above 40 mph, but as we all know, not everywhere you go you can floor it and hope to not get pulled over.
As of 2 days ago though, my cooling fan has stopped working and now my odometer has also stopped. I'm gonna assume an electrical issue now.
I have had 4 mechanics, not including myself look at it. It's a good running car, but most of these issues are expected with older cars, and seeing as how mine is 15 years old now, I just wish they didn't all hit me at once. A $600 car isn't worth $2,000 in repairs to save $5 bucks a week in gas from home to work.
Good luck to everyone else, but I'm saving and getting a new car. And for the record, Saturns aren't that bad, we just got our share of lemons or bad previous owners.

I also have a 94 SC2, and when I got the car in 07, it was a really good car and it ran really good.
Yeah it does have over 200,000 miles on it now, but I now need the motor mounts replaced, I need the transmission worked on, and I need the sun roof fixed as it has gone out
It likes to try to over heat unless I have the heat on, which sucks during the summer time, and it hates reverse; it slams into reverse really hard.
It ruins any kind of electronics that are plugged in to it. I have gone through 3 radios cuz the car likes to eat them.
Pretty much it's a bad car now. Pretty much the only good things on the car are the motor and the A/C haha.
I just wish all the problems hadn't hit me all at once, seeing as how I'm a college student and only work part time :(

I have a 1996 Saturn SC2. The radiator fan no longer runs. I checked the relay in the fuse box and replaced the fan motor. Still nothing. Can someone give me directions on how to wire the radiator fan so it runs all the time? Thanks.
