Coolant level would be a sensor going into the fill cannister on the left side of the engine bay. Temperature would be done with the sensor just below the EGR valve on the engine just above the transmission bellhousing. Tiny little wire going into a single plug sensor.

Well, I've got a 93 SL2 that has 170,000 miles on it, and aside from standard maintenance such as oil changes, tune-ups and the like, it runs like a champ. I've got the 1.9 litre DOHC Motor, and the Manual Transmission. I love the car to death. I deliver pizza for Pizza Hut and put anywhere from 50 to 100 miles of hard use on my car per day. It has taken more abuse from me with less complaint than any other car I've owned(more than 20 cars). It's fast(0 - 60 in 6 to 7 secs!), efficient(28 mpg) and fun! Saturn comes highly recommended by me! :) Beware! The SL1s and SL2s from appr 1991 to 1994 are very sensitive. I just had my engine replaced (92 SL1) and spent appr 3700 on the job (including tow trucks and a crate engine and the mechanics time). I was told by my mechanic that if I had the SL2 for that year the job might have cost me up to 1500 dollars more than it did. The difference between the two models is that the SL1 has a single overhead cam, the SL2 has a dual overhead cam. I love my car, and its zippy and fun, but it needs more frequent tune-ups than are recommended, even by the manufacturer. Just my personal experience. I have a 1995 SL2 manual trans. I deliver pizza for domino's, I've put 45000 miles in just one year, it went through snow, rain, and mud, the only thing I've done was regular oil changes and basic tune ups. By the way my sat have 150000 miles now and still runs like new. I love my saturn, it's by far the best car I've ever owned!! I have a 1993 Saturn SL2 and my buddy has 1995 Saturn SL2. Trust me, we would like to burn them to the ground, useless junk.

I don't know if it would be the same way with an SL2, but I happen to have a 1996 Saturn SL1 that I replaced the alternator with and this is what I had to do to replace it. First you have to get the car on a lift. Then, take off the passenger side front tire and then there is a plastic splash guard you have to remove to gain access to the alternator. In order to remove the alternator you have to take the tension off the pulley by releasing the serpentine belt. Then, remove the 3 bolts that mount the alternator. but before you remove any electrical connections to the alternator, disconnect the main negative of the battery to prevent shock or a power surge. I have a 97 SL2 and I have done the alternator. Everything he stated is correct. A few additional points. The mounting bolts are very hard to see and you will need to rotate the pulley to get to all of them. Once the alternator is free it needs to be removed through the wheel well. It won't appear to fit anywhere but it really does. Additional points: I have changed alternators in SL2s about a dozen times now (much to my chagrin). 1. Before you even BEGIN disconnect your battery completely. You can cause serious damage to your alternator and car computer if you do not. Better to err on the side of caution you see. 2. The other safe thing to do is to remove the serpentine belt BEFORE you get the car on a lift device. 3. Next, raise the car on a lift so you can get underneath safely and easly. 4. Remove the passenger side front tire and splash guards. 5. Remove the electrical wiring from the alternator. 6. Remove the bolts on the alternator. (Taking care to have the alternator secured before removing the last bolt. 7. On many Sl2s upon removal of the last bolt, you may place your hand underneath it, and give it just about a quarter turn, and slowly slide it through an opening below the alternator that looks as though, and may feel as though it should never fit through. You can do this by giving it that quarter turn, and then sorta spiraling it through the opening in a slow and decisive manner. Repeat these steps in reverse order to insert a new alternator. The first time i did this it took me an hour, the second 1/2 hour, and there on out it only takes me about 15 minutes. Its a very simple process, almost as easy as changing your oil... the hardest part is undoing the bolts. Be safe. ben

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.

The coolant light is supposed to indicate when the coolant level is low. If you're certain that the vehicle coolant level is up, check the electrical connections and finally the sensor.

The amount of coolant it will take to fill your vehicle is dependent upon how low the coolant level is. You can add coolant to your coolant reservoir. The reservoir will have an indicator of when the coolant system is full.

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.

The plastic coolant reservoir on the fender feeds directly into the coolant system. Just add coolant to the reservoir and if you have drained the coolant or otherwise emptied the system, you may need to check the level in the reservoir after running the engine, or more accurately, after the engine has cooled. Once the coolant level has stabilized, just check it periodically to make certain that the coolant level never gets too low.

If the low coolant message is on and you are certain that the coolant level is up, then you probably have a faulty sensor or sensor connector. The low coolant indicator should turn itself off as soon as the coolant is filled.

Check the level in the coolant reservoir. There is a line "wall" in the jug. The coolant level should be just above that line. If it is then check if your reverse lights work. They are on the same fuse. If they work, you probabaly need a reservoir as the level switch is faulty

Look on the ground! Monitor the coolant reservoir.

If it's an older vehicle - no. But a newer vehicle might just be clever enough to monitor the coolant level and refuse the engine to be run empty.

7 quarts of coolant will fill your sl2

Your reservoir may be low. This will trigger the coolant light. It is often a malfunctioning sensor and nothing is actually wrong with the cooling system or coolant. It can be easily replaced. Alternatively you can leave it, but monitor your engine temperature and coolant level.

A 1995 Saturn SL2 will hold 7 quarts of coolant. Saturn vehicles are no longer made but can still be serviced by GMC dealerships.

There isn't one. You refill the coolant with by putting more dexcool (DO NOT USE THE GREEN STUFF (ethalene glycol) ) in the coolant overflow bottle.

You can, so long as you monitor your coolant level. You'd be best advised to have the leak repaired ASAP.

To check the coolant level of a vehicle first see look for the overflow reservoir. There should be a coolant dipstick with a level gauge on it. Remove it from the reservoir to see the coolant level.
