-We have a 99 Buick with 38,000 miles. At 30,000 miles the car overheated and we had to find a mechanic in unfamiliar area. He told us car was unsafe to drive unless we had new radiator system installed (water pump, radiator flush, pressure test, radiator system flush, radiator kit (premium), anti-freeze - 2 gallons, lower and upper radiator hoses) at a cost of almost $1200.
FYI the car is in Florida full time - under cover.
Recently the "low coolant" signal has come on and after checking with a local mechanic, he said the manifold gasket was leaking and it could be fixed for about $600. We are reluctant to spend that money unless we can feel somewhat certain that the main problem is solved. We understand that at some point there was a class action suit against GM because of problems with Dex-Cool which is the required coolant for GM cars. In the meantime, we have been adding plain water to the reserve tank but are very concerned that this may cause additional damage. There is never any leakage under the car.
Buick - Century :: 1997 - Overheating / Low Coolant Light Flashed On Dashboard
I have a '97 Buick Century. I noticed the smell of coolant, and the "Low Coolant" light flashed on the dashboard. However, according to the temp gauge on the dashboard, the car was at normal temperature. I pulled over and opened the hood. The coolant in the overflow tank (not the radiator) was boiling, and sputtering out.
I took the vehicle to a nearby shop, where they said it needed a new "Coolant Level Switch." They told me they put a new one in and did a coolant flush, and sent me on my way.
About a mile down the road, the "Low Coolant Light" came on again. I pulled over and found that there was ZERO coolant in the engine. I filled it myself, and continued driving. Over the next few days, I checked the coolant every day and it stayed normal. I drove a bit, but never more than a few minutes, so the car didn't have a chance to overheat.
Then, today, I drove it a good distance for the first time since the original incident. After a few minutes of driving, I smelled coolant and pulled over. The coolant in the overflow tank was once again boiling and bubbling out. What it might be?
Century :: 2000 Buick Cannot Get To Start
I have a 2000 Buick Century that I cannot get to start. While my wife was driving home it started to sputter (like running out of gas) and did a little back firing. She made it home and I put in some gas (Just to make sure) and the care cranks over but will not start. I have replaced the fuel filter, checked the spark plugs and replaced the CAM Sensor. The car still will not start.

2000 Buick Century Custom with 140K miles: Service Engine Light came on. Re;placed gas cap, light still on. Took to dealer who replaced HO2 sensor, light still on. Took to dealer who found no problem but charged $100 for looking. Light still on. Took to dealer who said it needed two major parts. Light still on. Took to another mechanic who could find nothing wrong. Light still on. Is there hope?

My 2000 Buick Century has both ends of the front sway bar broke partially at both ends-the bottom half of the flattened tubular terminal has cracked away. Would it be worthwhile to just have the cracks welded back together without removing the sway bar from the car, after removing the sway bar from the bushings and mounting bolt hardware?

My 2000 Buick Century has an issue that whenever it rains really hard, after driving a while the ABS, Trac Off, and Service Vehicle Soon lights come on. I am assuming that part of the electrical connections are getting wet and causing the lights to come on. When there is no rain, obviously the lights don't come on. It's only done it one other time and it did it today. I was just curious what to do to fix it, before I jump into looking at all electrical connections which we all know can be hard to diagnose. By the way, the car has 64,000 miles on it if that makes any difference.

I have a 2000 Buick Century. The wiper controls are all goofy. The delay seldom ever works, just goes into slow steady speed most of the time. And they go through several more cycles when wipers are shut off. No doubt some entire multifunction module will have to be replaced.

Issues with the transmission in the 2000 Century. My car shifts perfectly fine cold, but once it warms up it shits hard between all gears. Downshifts are never an issue, just up shifts. To me this sounds like both shift solenoids may be sticking or shot... I have already drained the fluid and changed the filter, added lucas tranny stop-slip, drained that out and replaced fluids again... no codes to go by and no high revs before shifts when accelerating...

View 2 RepliesCentury :: 2000 Buick Won't Start - Making One Click Then Electric Swirling Sound
I have a 2000 Buick Century and i just recently had the fuel pump replaced because it was totally shot. Everything was fine except i realized when i started it sometimes it would crank really slowly, i thought it was the battery because the one i had in there was like 4 years old. One day it just straight up wouldn't start in a Public parking lot so i bought a new battery and it still wouldn't start. Every time i try to start it, it makes one click then a weird electric swirling sound, but wont crank at all. My buddy who has a lot of experience with cars thinks its the starter. We tried banging on it but no luck. How to confirm if this is the starter?

So I have a 2000 Buick, and it generally starts. However, twice now at random times the car hasn't started. It doesn't turn over, but makes a buzzing sound. The strange thing is, that usually after leaving it alone for a few hours, it will start as though there are no problems. I assume it's some kind of electrical issue, but I would love some input on the possible problems with my car.
View 2 RepliesBuick - Century :: 2000 - Transmission Will Shift Hard After Stopping At A Light Or Stop Sign
I have a 2000 Buick Century that only has 70000 miles on it. I have an issue that when I drive the car for a while, the transmission will shift hard after stopping at a light or stop sign. It only does it through the first three gears. If I shut the car off and let it sit for a few minutes and start it back up, it shifts fine through all of the gears. I have not had the change to change the fluid and filter yet. The fluid looks clean and is always full. I have read that there has been a common problem with a pressure control solenoid in the transmission needing replaced to correct the hard shifting. I am not getting any kind of error codes from the PCM, so I am not sure.

View 4 RepliesCentury :: 1994 Buick 3.1L Running Hot / Not Overheating
I am having a very tricky problem with my Buick.
For approximately the last 4 months, it has been (at least according to the heat gauge on the dash) running pretty hot. Not overheating, but getting close. And it doesn't take long for it to get there. This all seems to have begun right around the time that my father and I flushed the coolant system.
Since then, I have replaced some parts, and learned a few things in the process.
I learned that there are bleeder screws which can be opened to let air bubbles out. And I have heard that the 3.1L is especially susceptible to them.
New parts which I have installed:
- thermostat
- coolant temperature sensor
- radiator cap
- upper radiator hose
- lower radiator hose
I have checked the water pump and it seems to be perfectly fine. No leaks. No signs of bad bearings. And it circulates coolant just fine. I have not been witness to either cooling fan, primary or auxiliary, switching on in a while.
The exact symptoms are these:
The heat gauge does not take long to get to mid-way point, but will sit at that point for a bit if the vehicle remains stationary. Once the vehicle is in significant motion, the heat gauge will climb fairly quickly, especially with moderately high RPMs. It WON'T touch the red though, but will get very very close to it. The car runs fine. It does seem to be a bit underpowered, but I am comparing it to my fiance's 1996 Olds Cutlass Ciera, which I believe has a different transmission. My Buick does not seem to have lost power since this problem arose. The cooling fans no longer kick on. The oil appears fine. The coolant as well. With the radiator cap off, coolant does not bubble out or shoot out.
I made sure after changing upper and lower hoses to fill the radiator, let the car run long enough for the thermostat to open, and then slowly poured more coolant into the radiator until it was full again. And the reservoir is at proper level and the the reservoir hose s not clogged.
I am not SURE, but I don't believe the radiator is clogged. I believe that covers it, at least as well as I can.
BTW, I do not know where the fan relays are, otherwise I would test the fans to see if they still work.
What the heck is up with my Buick? Also, it has 97,xxx miles on it, and the transmission fluid is at proper level and looks normal.
Pump :: 2002 Buick Century Will Sometimes Not Start
2002 Buick century will sometimes not start. Seems to correlate with warmer weather and happens after long drives. I try to restart within 10 minutes of turning off and it will start and then in a few seconds the car shakes and the engine dies. I can restart multiple times, but it will always die in a couple of seconds. If I wait an hour and retry, no problem. Once someone banged on the gas tank and that solved it. Mechanic cannot diagnose problem unless it dies while he is there. Should I replace the fuel pump or could it be something else?
View 4 RepliesBuick - Century :: 1995 - Idle Getting Rougher
My grandpa's old wood paneled station wagon is sick. The idle seems to be getting rougher and rougher with every time I kill the battery (I've somehow left my headlights on four times in the past two months and needed a jump). It's to a point now where if I don't throw it in neutral at stop lights and keep a tiny bit of gas on the engine it stalls out.
Notes:*When it first gets jumped after being dead, if I stop even for a second, it dies instantly.*While cruising - it is fine. *It idles smoother stopped in neutral than it does stopped and in drive. *It seems a bit rougher with the engine is cold, but still rough and can stall with the engine hot. *Some random times it idles just fine (like for example the first few seconds on start up, and then it sounds like the engine is decreasing in rpm automatically, and then it is rough again).
Could the dying battery and rough idle be related?? The battery guy says "if it starts fine, the battery is fine" (it does start fine, although keeping the radio on for 20 minutes without it running will kill it).
Also other problems with my car in case this has anything to do with it: *I have a leaky tail pipe*my ABS has recently been randomly engaging at low speeds (next problem to work on...)
Buick - Century :: 2001 - Sounds Like A Jet Engine
I have a 2001 Buick Century that started making a noise from what seems to be the engine. It sounds like a jet engine when I accelerate. The noise is still there when I cruise, but it evens out. It is loudest when going between 40 and 50mph. The car is not overheating, and other then the noise it drives fine. My husband at first thought it sounded like the catalytic converter had been stolen, but he rarely knows what he is talking about. What could it be?
