#659 of 1497 How important is steering system flush? by jimsxn Oct 13, 2002 (9:19 am)
I bought this Le Sabre when it was 135K Km and now it is almost 165K and I don't know when it was last done. I received a notification from the dealer the other day for a steering system flush. How crucial is it and do I need a dealer to do it?
#660 of 1497 RE: tomcat630 What's your point? by fordnightmare Oct 16, 2002 (5:21 am)
Yes, it's 12 yrs old. Big deal. Are you saying I should heap it because it's 12 yrs old and the power windows are slow? I'll put in the replacement motors and keep it going if it's OK by you.   It runs like new with the new suspension and tires I had put on. Engine oil change every 3K and very well maintained through it's 90K of service. Body shows minor surface rust, but otherwise, it's going to keep running for another 50-70K.   Please do not comment if you don't have anything constructive to say.
#662 of 1497 Tires by kcwolfpack59 Oct 21, 2002 (7:57 pm)
Got Yokohama Avid touring for the 2000 Limited which has the 16" cross lace with General tires. I bought them based on the recommendations from Edmund's tires, tires tires forum and the rave reviews on tire racks web site. So far, I like them and they do make this smooth and quiet car a little more so. I almost got the Michelin X-one, but I have some on the Monte, and I think they are somewhat noisy on coarse pavement. I have had great luck with michelins over the years and just wanted to try something new. I will update if anyone is interested after a few weeks.
#663 of 1497 Plenum on the 3800 Engine? by vlanman25 Oct 22, 2002 (4:41 am)
My 1998 Olds 88 (yes Olds not Buick because the 88 Olds board is dead) with a Buick 3800 engine has been using coolant. The GM dealer says the "plenum" is bad, leaking, and must be replaced. I suspected a head gasket. Apparently this is similar to an intake manifold, but I'm confused in that I wouldn't think it had coolant running through it. Has anyone else experienced this problem and does a "plenum" have water in it as stated?   Even though the car has 54,000 miles, GM has offered to pay for parts replacement of $700, $530 is mine for labor. I have had several problems with the car even though I tend to baby it. At least GM is acknowledging some responsibility given the car's age and milage.   Regards and safe driving,   Vlanman

Hot coolant goes up next to the throttle body from the metal air intake to warm the incoming air. It comes back down to the metal intake. The leaks occur around the gaskets, I was told and shown, often toward the back of the engine. The leaks may be caused by warpin of GM's badly made plastic air intake. Mine did this -- $300 plastic part + $150 labor approx. A friend's 98 Pontiac just leaked into the air intake causing the engine to sound like a diesel then quit. Repaired, but I notice their car is gone again. They had a noisy lifter after they got the car back from 100 miles from home where it quit! Must have had an additional problem after the repair. Hope it wasn't bearing damage due to coolant in oil.   GM paid nothing on mine at 76K. I had another LeSabre with 149 K on it. I'm looking for another car. Would you buy another engine with same plenum design?????? in a new Buick or other GM car????????    Consider yourself lucky they're standing behind their product. I was given the cold shoulder "Why are you so dumb to ask for us to pay part or all for our bad design?" treatment by the rep on the 1 800 4Abuick number.   But later 1 800 4abuick was real nice when I asked about the options on a new LeSabre and why the packages are so screwy in what you have to get to get what you want? Apparently they don't connect customer service with sales of the next product unit.

Thanks imidazol97 for your interesting experience and information on a plenum. I agree with you completely, it's hard to get excited about buying any vehicle made so poorly. They'll probably fix that problem, but how many more poorly designed parts are waiting to get you.   I had the same thoughts about engine damage in my car. Hopefully no damage occurred and I got it to the dealership in time. Who knows what they did though, charging for a new starter, saying it was damaged by coolant and cracked?? I doubt it, but it was changed at any rate.   Thanks again for the info and regards,   vlanman25
#666 of 1497 Buick Power Door Lock Problem by upandaway1 Oct 27, 2002 (1:18 pm)
I have a rear power door lock problem in my 86 Buick Electra, which is very similar body to the LeSabre and the Park Avenue. The lock doesn't respond to either the lock or unlock commands. Its locked right now and I can't open the door. Its probably not important, but the power window still works. Any ideas on what to do to fix it?
#667 of 1497 Re: Power Door Lock Problem by mlm4 Oct 28, 2002 (10:30 am)
It's probably a bad lock solenoid. You'll need to remove the door panel to get at it. Try and move the lock manually to make sure it's not jammed.
#668 of 1497 LeSabre fuel filter by shivelyt Nov 04, 2002 (5:01 pm)
I have a 95 LeSabre with 75K miles and, so far, not too many complaints. When I had the oil changed last the service agent told me I should change my fuel filter. Can't find anything in the customer manual about this and can't find anything resembling a fuel filter under the hood. He told me it was under the right rear wheel. Maybe he meant the fuel pump. That I replaced a year ago for about $300. Anyone have any ideas on this? Thanks.
