Buick LeSabre



  • I had a Buick Lesabre years ago. It too was losing coolant and drove me nuts tryign to find the leak. Luckily before I tore off the heads, I checked all the hoses. It turned out that there is a small 3/8 inch diameter coolant hose, about an inch long, buried around the plenum and intake manifold. It had a small enough leak to simply burn off on the exhaust pipes. I think this has something to do with the fuel injection staying cool??
    I was shocked to find the part cost less than $10.
    I wonder if this happens often?
  • I fixed the dash rattle in the 2000 Limited by inserting cut off pieces of a rubber windshield wiper insert into the gap between the A pillar and the dash. The a pillar rattles against the windshield. Experiment around some by tapping your fist in that area. You will quickly see what I mean. I also found a rattle in the ashtray in the middle of the dash. I got a small stick on rubber disc from a hardware store to silence it. That wasnt as annoying as the A pillar rattle, though

    I just purchased a 2000 LeSabre and love the car. I traded in a 93 LeSabre, and I can not believe the difference between the two! The 2000 is a Custom model, but loaded with leather, 16" cross lace wheels, driver info center, sunroof, and what I think is the best feature, the Universal garage opener. It took about 45 minutes trying to get the opener to store my codes because I followed the directions and held the openers several inches away. I finally got frustrated and held it right against the overhead opener, and it instantly grabbed and stored the codes.(So much for following directions.) Every GM 3800 engine I've had in other cars would idle around 900 RPM and would cruise at 65 MPH around 2000 RPM. This LeSabre idles around 600 RPM and cruises at 65 MPH between 1500 and 1600 RPM. I don't have the Sport Suspension package which I know uses a different final axle ratio, so I don't know if the tach is recording properly, or if there is that much difference between my 1999 Olds 88 readings. Just as a side note, I have always driven Oldsmobiles except for the 93 LeSabre, which was from my mother in laws estate. Love those big GM "cruisers" and am 50 years old.
  • I just read a disturbing article about 44 engine fires in Buick LeSabres. Does anyone know if GM has addressed this problem? The government is investigating.
  • Just got my 2001 Le Sabre back from the dealer.

    The rattle turned out to be some loose air bag fasteners in the steering column. Fixed under warranty.

    At the same time they fixed the driver's heated seat. It took about a month to get the part that was back ordered. Makes you wonder about the durability of the heated seat element.

    I am beginning to think that I will have to carefully consider the merits of the GM extended protection plan given the large number of electrical gizmos on this car.

    Just took delivery or my 3rd LeSabre.
    After reading comments about ride and wheels _here_ I chose the 16 inch wheels with Michelin Symmetry tires.
    The ride is more controlled than '98 Limited I have. It's perfect.

    Tires and wheels are quiet.

    Just wish I could have avoided paying for OnStar as a required part of every option combination that I wanted -- no way to avoid it and get the individual options I wanted. OnStar must be the new profit center -- dealers use "packs", GM uses OnStar, grin...

    Any comments from other owners or recent LeSabres?

    Nice choice. We had a 2002 LeSabre Custom rental for a month when our 300M was being re-built after a wreck, and fell so in love with the car, we planned on buying one once we got the car back. Didn't end up with one, but I still think it's one of the nicest cars on the road for a great price.

    Some post in the past said that the Park Avenue an LeSabre
    were assembled on the same line as a 'Cadillac Model. What
    one was that? _-- or am I remembering wrong?

    Like several large GM cars, the LeSabre rides on the G-Platform. Because of this, the LeSabre comes off the same plant line as the Buick Park Avenue, Cadillac Deville and Seville, Pontiac Bonneville, and the dying Oldsmobile Aurora. Hope this helps!
  • There is a vibration, when at idle that disappears when car is put in neutral..Old buick, that I love, has 120,000 miles without any problems to date, except an alternator, two water pumps, and a coil. great car.
  • imidazol97imidazol97 Crossroads of America I70 & I75 Posts: 21,317
    Have you replaced plugs and wires? I did that at 90K.
    My great service manager at small town dealer told me
    to do that on both 93 and 98.

    Do you feel the vibration the same in reverse and drive?
    I assume you've looked for hoses or wiring bundles
    that might be transmitting vibration
    when engine is twisting again transmission load?

    Have you checked the PCV valve? It may be not sealing
    closed at high vacuum at idle if it's dirty and gunked up
    if the oil ahs not been changed regularly and often?

    If engine oil's been changed regularly and you don't think
    the roughness might be something major in engine, you
    might try some Techron engine cleaner in gasoline (available
    at most mass parts stores and some others now line Meijers
    in Midwest). Try one in tank when low with fillup of GOOD
    brand gasoline (I use Plus or Premium). Then do it again
    within a half of a tank after the first gas is run through.
    It's got one of the best cleaners in gasoline (Exxon's brand
    of cleaner for their gasoline).

    These are things I found from my 93 LeSabre. Too there was
    a prom update for roughness at load at lockup on the torque
    converter under light throttle at 50 or so. I thought it was wires
    and plugs, but BUICK had a mixture change and a change in
    the lockup speed for torque converter -- it won't lock in until
    50 mph. It used to lock in at 45. That way you don't notice the
    roughness under load since the converter is not locked up.

    Good luck.

    Thanks Beach15!
    That's what I wanted to know.
    Is there a webpage that explains the differences between
    the various models by platform? Or explains the differences
    between the Seville, Deville, Park, and LeSabre that
    come down the same line?

    Not sure of any specific website that describes the real differences between cars, but I can look. Also, from experience, the only main differences in the G-Platform among the cars it is used are slight variations in wheelbase, and really diverse suspension tuning. The LeSabre, for example, is tuned the softest of all its "relatives", while the Pontiac Bonneville SSEI is tuned the firmest, with the stiffest shocks, springs, and roll bars. In between those two are the other Bonneville models, the Aurora tuned for sport/luxury, and the Deville and Seville, both of which come in a few specific flavors of their own. In addition, most offer variations in stability control systems, but are all very similar as far as overall width.

    It is also common that the many suspension pieces, for instance, are interchangeable between the various cars. One of the most significant differences are engine choices and differences.

    Overall, every model is quite closely related. Hope this helps, and I'll try to answer any other question you may have, if possible.

    That's a very good post.... I own a 94 LeSabre and it's fast even without a supercharger but a little wallowy. So what you are saying is that SSEI's suspension components will make it firmer around corners? What particular components would make the most difference?

    My dealer was replacing rear struts on LeSabres back in
    92 93 to satisfy some customers, using Pontiac SSE or something
    like that struts. They were the last ones without air leveling in the
    rear. The dealer put those Pontiac struts on to stop the front-back
    wallow the soft LeSabres had. In my 98 with air leveling on
    rear is much stiffer than 93 Custom was. I replaced 93 struts at
    35 K because I couldn't stand the soft wallow it had. Replacements
    fixed the problem. (Monroe struts.)Replacements were same for
    Pontiac, Olds and Buick cars...
    It did not have air leveling on rear.
    Just traded it for 03 Limited. New one is almost too stiff. But only
    has a few miles on it. What an evolution in ride.

  • I have a 2002 LaSabre and the AM Radio reception is awful, static and noise. I have had the radio replaced once and now the dealer says it is due to the poor reception in the Poughkeepsie area--funny my wife has no problem with her 1989 Olds. Has anyone else been experiencing this problem? I would like to know how to get in touch with Buick to seek their help.
  • tpkentpken Posts: 1,108
    You may wish to have the dealer check for breaks in the circuitry of your rear window defroster. It definitely affects radio reception and in my case I got a brand new rear window for my '00 Bonneville under warranty because of that problem. When I turned on the rear window defroster the AM reception was complete static. FM was unaffected. Good luck

  • beach15beach15 Posts: 1,305
    Well, yes I would say so. One must remember that the pre-2000 LeSabre & Bonneville are completely different cars than the '99 and older models. As such, you may be able to tighten your '94 LeSabre up with Bonneville parts from the same or a close model year.

    imidazol97- Too stiff? I've ridden in a 2002 LeSabre with the standard suspension, and another with the GT suspension and I can't imagine how you could even remotely use the word "stiff" in describing either. Boy, you really must be used to a floaty, sailboat ride!

    "even remotely use the word "stiff" in describing either. Boy, you really must be used to a floaty, sailboat ride!"

    Beach15: criticism accepted! You're right on.
    I'm used to soft 98 LeSabre Limited. Great interstates, controlled, but smooth. Hit a wavy road and it's not controlled at all. 93 was even softer.

    But 2003 has less than 1000 miles on it. It's taut! Michelin tires and 16 in. wheels. It's like a friend's Jetta felt driving on interstate highways. I haven't had it on Ohio sideroads with waves and hills in them yet. I like the feel of the 2003.

    I'd like suggestions on what struts to put on the '98. I put Monroe road sensing struts on the 93 and they were tight for 40K -- got a little soft after they were on for 100K. Does anyone have suggestions of good riding but controlled struts to use?

  • I just noticed my 93 lesabre rev to 3.5 rpm while doing 80 kms. It stayed that way until I pulled over to check the tran oil. Oil was fine and the rev went back to norm.
    Took it to my tran mech. and under a quick scope said it could be a faulty torque converter or electrical.
    He also said if it was a torque converter I was looking at a 1000 dollar bill. Wont know until a full scope determines.
    My question is , is this a common occurence for a 93 at 177,000kms or am I being scamed? What can I do to make sure?
  • imidazol97imidazol97 Crossroads of America I70 & I75 Posts: 21,317
    At 3500 rpm at (52 mph) 80 kph, that sounds like
    it dropped into 2nd gear. Were you accelerating and it stayed in 2nd gear? Could just be a one-time quirk. I'd be tempted to drive it and just be alert to strangeness in characteristics.

    You might ask at a dealership where the service manager knows and shares info about others of year and age and mileage they are seeing -- if they have any problems or not. My service manager told me about a Century trans that was rough, drive it and if it goes out completely it costs the same to replace as if you try to troubleshoot it early.

    You might clear the computer by taking out the fuse for a few minutes. Disconnecting battery loses radio settings and might lose remote opener settings.

    My 93 with 150K miles had no trans signs like that. IT was a solid piece -- better than 98 LeSabre trans feels in the other car.

    Good luck.

  • The first LeSabres I checked on were the 1984 and 1985 Limited sedans. I admit. They were built more solid than the 2003 Limited I just recently checked. And the older ones were longer and had more passenger room. But they were not as fuel economical as the 2003.

      It is equipped with a 3800 Series II V6. However, after checking under the hood, I found there is plenty of room for a bigger V6 or a V8.

      I did suggest this to GM for 2004. They got back to me. And they told me they are seriously considering it. There is more.

      The one I checked was equipped with all the standard and optional features available for the 2003 LeSabres. But due to its smaller engine, it was overpriced. I hope a bigger engine is added.
  • jimsxnjimsxn Posts: 108 not go together well. This is a serious chassis design issue. GM would be loathe to introduce waywardness in this best-selling quiet luxury rig. That said, I hope they come up with a way to make LeSabre more powerful and more responsive.
  • mlm4mlm4 Posts: 401
    Agreed that front-wheel-drive is not the best for high horsepower setups, but the Bonneville (same platform as the LeSabre) offers a supercharged 3800 Series II, and next year a 300 HP V-8 will be offered. Also, the Aurora (also same platform) offers a V-8. We're not talking about smoking power here, but people have modified their supercharged Bonnevilles and Grand Prixs (for example) and been able to get good performance without any handling sacrifice (or so they say; I haven't done it myself).
  • I think Buick is blowing soot up your tailpipe and here is why. Buick puts a supercharged V6 in the car series just below the LeSabre (Buick Regal) and in the one just above the LeSabre (Park Avenue). Now the Regal's engine bay is smaller than the LeSabre and the supercharged engine fits in just fine. The LeSabre and the Park Avenue have the same dimensions underhood so the supercharged engine will fit the LeSabre just as it does the Park Avenue. My thought is that the LeSabre is the best selling full sized car in America for like 9 years running and they don't want a performance image ruining that. (Don't rock the boat-we have a good thing going) The Regal is a big engined Century and the Park Ave needs the power to handle it's weight and be competitive against those in its price range. Based on this I don't think you will see Buick adding a V8 or supercharger to LeSabre (but maybe a Park Avenue V8). Just my two cents worth
  • I heard on the radio that you should remove the new pink Dexcool antifreeze from your car or truck and replace it with the old green glycol stuff. Failure to switch will supposedly ruin the cooling system of the car after a few years. Is this true? Also, will the warranty be invalid if the green coolant is used?
  • I am tempted to switch. I replaced the water pump in my car because of a gasket leak which I suspect was caused by the dexcool. I flushed the system and put in new dexcool at 3 years but the leak happend after that. The cooling system looks clean. I have read in some Edmund's forums about dexcool starting to solidify. Try doing a search here in maintenace and repair for archived discussions or topics related to head gasket failure.
  • imidazol97imidazol97 Crossroads of America I70 & I75 Posts: 21,317
    The DexCool in my 98 is orange. Is this the same as the pink? or did they
    change the color???

    I'd like to hear from a person working at a GM service shop about this idea of
    putting in ordinary antifreeze. I'm willing to change each year if it ads to the
    longevity of the plastic parts etc.

    The sludging from the orange DexCool occured from running hot in some vehicles
    (Fords), I believe I read or heard that on a radio auto talk show. But mine began to
    show scum in the overflow at 3 yrs. I replaced it with lots of flushing...

    Is there a particular flush chemical to use to clear the DexCool for replacement with
    DexCool or with regular antifreeze?

  • If you do a google search for "dexcool problems" you will come up with a good snowy afternoon's reading. After looking at everything, I am still not sure what to do. I think I will just change the dexcool every 2 years and keep an eye on it.
