#706 of 1497 FWD and dollops of HP.... by jimsxn Jan 29, 2003 (6:36 am)
....do 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.

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
#709 of 1497 LeSabre 2002 Which coolant ? by danieltiger Feb 08, 2003 (1:52 pm)
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?
#710 of 1497 Coolant by kcwolfpack59 Feb 09, 2003 (7:26 am)
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.
#711 of 1497 DexCool replacement by imidazol97 Feb 09, 2003 (12:48 pm)
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?
#712 of 1497 more coolant by kcwolfpack59 Feb 09, 2003 (2:52 pm)
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.
#713 of 1497 Engine Knocks and only travel 15-20 mph by rawdog_3 Feb 09, 2003 (9:27 pm)
I was driving on to work at 45 mph, when at a steady speed, my car started slowing down and I pulled over to see what it was. I got out and I heard instantly my engine knocking loudly (while still running), so I drove (slowly) on to a parking lot but will driving, I was trying to go a little faster then 15-20 mph and I couldn't, all you heard and felt was a grinding sound from the engine. So I had it towed to a shop and they said that my car can NOT go in reverse, I had gasoline ALL over my spark plugs and the sound is internal within the engine. Now I wanted to know if it was sugar in my tank, how could it affect my engine so fast but if not then what could be the problem because my car was running FINE until that night.
#714 of 1497 Custom Best Seller Package by oregonaj Feb 18, 2003 (11:08 am)
We are considering the purchase of a new LeSabre. We'll get the "Custom" trim level since we're not fans of leather seats. We had some questions about the "Best Seller Package" ($1365) and hoped we could get some help from the forum.      1. How well does the Traction Control feature work?      2. Is the "Driver Information System" very useful? (And how does the "Tire Inflation Monitor" work?)      3. How good is the "Concert Sound II" speaker system? (It seems I remember some negative posts about it a while ago.)      4. Any other comments about the LeSabre?   Thanks for any help, Jim

The tire pressure is based on tire rotation rate -- same info used for the ABS and the traction control. If a tire gets low, it rotates more than it had been relative to the others due to the smaller effective radius.   The traction control clamps the brakes on the spinning tire like ABS in reverse. It gives a more solid feel in the snow here in Ohio this weekend. But I've not tried it on ice. I'm pretty smooth in snow having grown up in Indiana, so the Traction Control hasn't come on much. I have wanted to try to do something to get the StabiliTrac to work, but I'm afraid to do that with my New Toy. The radio I have is a Limited with 8 speakers. I think it's a different model than the 6 speaker or 4 speaker that's base. It sounds great. I don't expect my car to have AR2a-like speakers for quality like my home. The older Limited I have with 6 speakers is very good. And the 93 that had the base 4 speaker system served me fine, but could have been better.   I'd suggest taking an actual car on a test drive if you're looking on a dealer's lot. They should be willing trade below invoice by now. You should be able look on a lot and say I'll give you this much for _that_ one bottom line, and if they don't want to trade, try the next dealer. Things are slowing down in the economy.   If ordering, I'd suggest the open web wheels with 16 inch radius and larger cross-section tires. I'd consider side airbags too. They're in the SE package and Limited.   Driver information center is neat to playwith while driving because it shows mpg instant and average over a trip since you reset it. The voltage is given exactly to tenths, so you can check on battery charge and degradation with age. The water temp is given, along with the computer's estiamte of how much damage has been done to oil quality by cold running, frequent starts, etc. , but I don't trust that computer for oil changes. I change my oil (myself) at 3000, or 2500 in winter, and maybe 4000 insummer if longer highway trips had been taken. My 93 engine had 155000 on it and didn't smoke, and didn't use oil beyond a half quart in 2500 miles..., even when I drove it 140 miles on interstate round trip.
