#281 of 575 Re: When to Change Oil Buick 2003 Century [shebail]
Apr 05, 2007 (5:42 am)
If Diesel engine, do not do this, or check approval for use if new diesel engine. May not be approved for rotary or diesel engines. Check owner manual first. Check it out first!
I just want to say that we switched to all synthetic oil, and cannot believe the difference in the mileage and overall performance of our car (1996 Century.) I believe this applies to all vehicles, except diesels and rotary engine. You can buy it by the 5 qt. container. Do not be fooled by the difference in price. In my opinion, you will save in the long-run. The engine runs much cooler thru the summer, even when sitting idle in 95 degree weather, without "asphaltizing the oil". This is true in cold weather as well. Engine will last longer and endure more. Lubricity is awesome, and oil changes are fewer. My husband first learned about it in industry on heavy equipment and we finally tried it on our own car. We will never go back to petroleum based oil. Oil changes last longer but they are so important. Ideally, you do not want to see the oil light, or the come on. Also, before trips and with oil changes, we are adding the fuel injector/carburetor cleaner. Mileage has improved 25% since we bought our vehicle, and that is after 165k miles. Running better than ever! The synthetic is compatible with the petroleum based, so you can add to engine either way. A good rule of thumb is to change your oil every 3k miles, but you can last longer with the synthetic between changes. With the price of gas, you need to consider changing. Nothing you read about it is gimmicky! Had we not changed, we could not have made the trips trips that we have made in the last few years. Please read about it first and use your own judgement.

You could have thermostat failure. Generally a simple, low cost fix.

Thanks for your feedback. I want to know the locations for this thermostat and if I can fix it myself.
#284 of 575 Draining Coolant on 2001 Buick Century
Apr 08, 2007 (6:37 am)
Good morning, I have a 2001 Century, just purchased from family member two weeks ago, it has since been driven over 3,000 miles, I got stuck in traffic and noticed the temp gauge riding up a bit, not past the middle but up enough to cause me concern,, I simply lowered the windows and put the heat on full blast till traffic eased. When stopped for the night I noticed the coolant overflow was at a proper level but the coolant looked kinda thick, I removed the radiator cap and it had grey goo in the throat.. I checked the oil and the level was good, and there was no sign of water/coolant... I purchased radiator flush and I am going to clean out the system,, but I can't find the drains, should I just remove the radiator hose (lower) and deal with it? Suggestions?? Thanks In Advance...

ROCKYFAN.....GO TO MESSAGE #98 AND #99. THIS SAME THING HAPPENED TO ME AND AFTER THE FLUSH AND ABOUT 20,000 MILES LATER I HAVE NO OIL IN THE RADIATOR. I CARRIED MY CAR TO A QUICK LUBE AND HAD THEM TO DRAIN ENOUGH COOLANT OUT TO PUT THE BOTTLE OF CASCADE IN THEN BLED THE AIR OUT OF THE SYSTEM WITH THE BLEED VALVE. AFTER I DROVE IT FOR A FEW DAYS I DRAINED IT AGAIN AND FILLED IT BACK UP WITH DEXCOOL. HOPE THIS HELPS. ABOUT THE DRAIN PLUG NOW I COULD FEEL IT , BUT COULD NOT SEE IT UNLESS THE CAR IS ON A LIFT. THAT'S WHY I CARRIED IT TO A QUICK LUBE.

Apr 08, 2007 (5:50 pm)
hi y'all, i have a 1990 pontiac safari wagon w/a 3.1 6cyl engine - same as the buick century...135kmi...recently it began to hesitate and buck when backing off the accelerator at highway speed...i had "woody" tuned up and the gas filter changed, but the problem persists and has gotten more dramatic...he has begun to idle roughly...would a 1990 have a engine diagnosis hookup...? if so would it be best to have a dealer track the problem... ? the wagon is in puerto rico and i am going to visit it soon and would love to eliminate this problem...
thanks for any advice,
#287 of 575 Need Help! 94 Buick Century
Apr 16, 2007 (10:22 am)
I'm having a problem with my blinkers. They come on, but stay solid, no blinking. Before they stopped blinking completely, they began getting really slow about a month before they died. I'd say, 1 blink for every 10 blinks normally. Anyway, I was just wondering what the problem may be. Is it possibly the bulbs? or does this sound more like an electrical problem?
Any help is most appreciated, since I have to get my car in order to pass inspection

Same car, same year.Had the same problem last year (first slow blinking, then no blinking), but only one side. Took it to Pep boys and all they did was replace the bulb and it worked fine after that. Hope this helps.
Apr 18, 2007 (6:31 pm)
Ok so I have a 96 Buick Century. None of the light are working! Well the blinkers are but thats IT! No head lights, tail lights, brake lights, interior lights? Nope not those either! I've got NOTHING! I have tried resetting the computer, replacing the head light switch, andchecked all wires. Nothing has fixed it. Has anybody else had this problem? What would fix it? PLEASE HELP!
#290 of 575 1998 Century heater fan squeal....
Apr 21, 2007 (10:13 am)
The heater/air conditioning fan squeals like crazy so she can't even use it. The dealership claims they would have to tear the dash apart to fix it and it will cost hundreds of dollars which she does not have. Does anyone have any other ideas on how to repair this?
