Saturn Maintenance & Repair



  • jillw2jillw2 Posts: 3
    Hi everyone,
    I bought my 2000 Saturn SL1 last fall in a private party sale. The car is in good shape, it only has 65,000 miles on it. Since then it has sporatically idled rather high sometimes when I put the car in park (it's an automatic). Lately it seems to be doing it a lot more. When I put the car in park it shoots up to about 2000-2500 RPM. However, it still does not do it all of the time. We put brand new spark plugs, spark plug wires and a starter in the car last Sunday. It seemed to temporarily relieve the high idle completely, but today it did it three different times to me, all when I put it in park. Any ideas? I'd really appreciate the help!!! I'm a poor college kid- how expensive would it be to have a dealership diagnos this, and should I? Any other hints? Thanks!

    Hello All,
    My car recently hit 50,000 miles on it and has had relatively few problems up until now. While driving I've noticed that the rpm's will increase even while coasting on a flat stretch. That is what first brought my attention to this issue. I was going around 35 mph and coasting when the rpm's jumped above 2,000 and then fell to around 1,000. I should mention that the car is an automatic. I've also noticed that when coming to a stop the rpm's will again jump and I have to hit the brakes hard to avoid hitting the car in front of me as the car revs. What brought this to a head is I was coming out of the store, the car had been sitting for 10 min max, I go to turn on the car and the rpm's don't make it pass 1,000 and the car dies. I retry the car 3 more times before it finally starts and I can get it home. My fiance has driven it and the only thing he's noticed is that when the car is going up a hill, down a hill or decreasing rapidly it makes a griding noise. Any ideas what can cause this problem? On a side note the car was taken from California to Georgia in a moving truck and I didn't have this problem before I moved. Could that be related in any way? Sorry if this is long I'm just trying to give an acurrate picture. Thanks for any help you can give me.

    I had the same problem with my 96 SL2. I changed the idle air control valve and it fixed the problem. The IAC is located in the air intake manifold area. I don't remember the cost but they are available at places like NAPA and auto-zone. You might want to check out a Haynes maintenance manual to find the exact location and how to change it.

    Thanks a lot for your help,
    My boyfriend installed the IAC valve today that we got from Auto Zone. So far, so good, I will probably post later if something comes up. Did you have any other problems after? Thanks again!
  • Nice forum!

    I have a 1996 SL1 and a couple of days ago the battery light came on and it won't go off. I can't seem to find the manual so if anyone has any ideas of what I should do let me know. Thanks.
    I've tried resetting the battery and didn't seem to do anything.

    Get a friend with a simple voltmeter and have him read your battery voltage with the engine running....if the needle on his meter doesn't go up when you rev the engine, or if the needle stays stuck under 13 volts or so, it's probably your alternator that is defective.

    Make sure your alternator belt is tight before you do this test.

    right now I bet you are running only on battery voltage so don't drive at night and don't go too far from home until you figure this out.

    It has been over a year since i changed the IAC, works good. I do remember there was a lot of sticky junk on the old IAC plunger, so after i changed the valve I ran a can of air intake cleaner through the intake. You remove the air intake boot and spray the cleaner in the intake with the engine running. It makes a lot of smoke and stinky stuff come out the exhaust, so if you decide to clean the intake make sure you follow the directions on the can. On the other hand, if it ain't broke, don't fix it.

    Also having starting problems. My wife drives a 96 SL and has been having intermittent starting problems. Every now & then the vehicle will not start. When she turns the key, nothing, no lights, no interior lights and no noise when the key is turned. She has to bang on the battery or move the cables before it will start. I have replaced the battery and battery cables. Saturn service has not been able to find any problems. Any Ideas..............
  • Thank you for the assistance. Well, I made it to work and it died today. I took it to my mechanic...still waiting for a response. But I'm sure you were correct about the alternator. I'll keep you up to date.

    Any AC gurus out there?

    I have a 92 SL2 w/o a working AC...and its getting hot! I'm relatively confident that the clutch has gone bad, but otherwise the system is good to go. I've never work on an AC system before...can anyone tell me if I can simply replace the clutch or if I am better off to buy a new compressor w/ clutch assembly? If I simply need to replace the clutch, should I be able to replace it without pulling the compressor or opening the system?

    8 weeks ago i filled my tank at a new after the service light came on.i drained the gas and after a few trips the light went off.2 weeks ago i thought i would try the gas station again.i used a higher octane.soon after that the service engine light came back on.after draining the gas and filling up 3 times at my normal gas staton.the service engine light still hasn't went off.and in the last 3 weeks the car has been hesitating and boging after it warms up.its getting worse by the day.the only thing i can think of is the fuel pump or filter.but i suppose it can be anything.I'm not really sure if it was the gas i used or something car has the ca emission on it.what do you all think.the car has 30.000 mi on it.thanks for your help

    I have a 1995 SL2 DOHC . The electric cooling fan does not come on unless the ac is turned on. I replaced the coolant temp switch (the one with 2 wires under the thermostat housing) but it still wont kick on. The t-stat works fine, there is plenty of antifreeze and the wires seem to be in good condition. Any suggestions would be appriciated.

    Ok here is my story, I got a new radiator, naturally the old transmission lines were rusted in there good, and ended up breaking off trying to remove them. So I purchased two transmission lines. While waiting for new radiator to show up in the mail I forgot which transmission line goes up top and which one goes on the bottom. On the transmission is two outlets they are side by side, and one is recessed a little. which outlet would go to the top connection on the radiator? or vise versa. Thanks for any help.
  • My '93 Saturn SL2, DOHC was fine when I stowed it a year ago. Today I'm getting it ready to drive again and discovered water in my oil! I've always believed that only a bad head gasket or cracked block could cause this but I'm wondering if it could also be the intake manifold?

    I have a 2002 Saturn SL-1 with about 34,000 miles on it. Sometimes, not all the time, when I start it, it acts like it is going to die. Once I give it a little gas it is fine and runs fine. I had a similar problem with another car I had and had to replace the air control valve or sensor (I cannot remember what it was called). The car runs fine once I start driving it, as did my former car before I had the sensor replaced. Any suggestions before I take it to the dealership???

    For three days I had no issues. Then the same one started to reappear. I really wish I could explain when/how/why, but it's really sporatic. One really hot day last week it idled high as I made my way slowly through construction. I turned the car off, then on again, and it was fine. Today I drove it six times, it idled high for two of those trips (when I'd stop at lights- it would be around 1000-1100 rpms). At first I thought it was happening after I drove long distances continuously, but then one day this was not the case. All of these times, when I turn the car off and back on, its fine again. I have an appointment at saturn for the middle of next week. Can anyone think of any possibly explanation?

    thanks steve
  • I have a 2001 SC2 (automatic) that i bought pre owned in 2003 at a private lot. The car had 42,000 miles on it when i bought it and now has around 72,000 miles on it. About a year ago my car began to randomly break down while i was driving. The RPMS would drop and i could not accelerate i could push on the pedal all i wanted and it wouldnt go. If i pulled over to the side of the road it turned the car off it would start again. Till one day it just wouldnt start, i got that fixed and it was my crank shaft sensor and since then it hasnt done it. But with in the last month i have noticed that when my car is in park the idle will not remain the same, it jumps up and down constently and sputters. And today my check engine light came on for the first time. I thought maybe it was my spark plugs and i am wondering if it is possible that my transmission might have anything to do with it, the car vibrates slightly when shifting from 1st to 2nd and shifts very hard when going from 2nd to 1st. Also the car once it warms up shifts really hard into reverse and it takes about ten seconds to actually shift into reverse.
    Anyone have any help for me?? :confuse:
    Thanks ~*Bobbi*~

    Does anyone know where GM got that 3.0L V6 engine? Is it from Opel (Germany), SAAB, or US made? I'm interested in it's expected reliability. My 2003 VUE has the same engine with 34K miles on it and so far it has it has been quite reliable.
