Buick - 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.

Buick - Century :: 2000 - Oil Getting Into Coolant

My wife has a 2000 Buick Century with about 150,000 miles on it. It has been relatively trouble free. Recently, the "low coolant" light began to come on.She took the car into a garage where she was told there was oil in the coolant and the sensor had been compromised. The cooling system was flushed and cleaned and a new sensor installed. The "low coolant" light continued to come on. She took the car back in. She was told the wrong sensor had been installed. When she went back for the car the second time, she was told the oil in the coolant was preventing the new sensor from working and there was nothing more the garage could do. I went in and asked questions, primarily how serious was the condition, and couldn't get a straight answer.

We are due to drive to Florida in November. My wife would like to take it to a garage there. Is it save to drive it as is? What are the implications of oil mixing with coolant? What is causing it to happen?

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?

Buick - Century :: 1999 - Odometer Stopped Reading Out

I have a 1999 Buick Century which I love. Paid for, low maintenance, reliable, good interior,........ But a few years a go the Odometer stopped reading out. Then one day when it was really cold I got a reading. It warmed up the next day and it was gone and has not returned. This part of the dash is digital not mechanical. I also can not read what gear my shifter is in (so I count 1= park 2=reverse 3=drive). I have been told that this is a cluster which needs tot be fixed. After they pull the dash, then the part, repair the part and send it back to be replaced. Really....there is no light or this could be seen.

Buick - Century :: 1999 - Security Light Blinking For A While Then Go Solid

Ok, got a 99 Buick Century that is a cantankerous old hag. It doesn't like to start sometimes. naturally when i really need to get somewhere. The security light blinks at me for a while, goes solid, then i cycle the ignition and hope it will start. It happens with multiple keys and remote start(which has been removed multiple times because each mechanic thinks that will magically fix it). No rhyme or reason, it sends no code, the local buick dealership couldn't figure it out. I think its my security computer. what is the easiest/cheapest diy solution besides get full coverage and leave it in the ghetto with the keys and hope it ends up on cops? battery is fine, it starts normally most of the month, just maybe a handful of times a month it won't. Starter I believe is still good as well, and gets voltage when it starts. Fuel pump audibly works all the time.

Buick - Century :: 1999 - Hesitate During Acceleration / Stalled - Code P0102

1999 buick century custom .. 3100 motor .. 200k+ miles ..

It all Started 2months ago.. once every few weeks my car would hesitate during acceleration (leaving a light for example) but just once.Then started it up one day and it was idling rough..also stalled out twice.

Dropped it off at a shop after hours so he could check it out in the A.M.he calls n says its not acting up at all.

Get the car back and drive it 2 more weeks..then it happens again. Rough idle and hesitating...take it directly to the shop but its acting normal again by the time I get there (starting to feel like im crazy)

So I take things into my own hands... I change air filter, clean MAF and throttle body. Change the plugs and wires.

start it up and it seemed to run better than it ever has.. for about 5mins.I took it for a test drive and it started sputtering and bucking and eventually died to the point of undrivable.

Got towed home.NOW it starts dang near everytime but runs EXTREMELY rough for a few seconds before eventually dying. It will run a bit longer if I unplug the MAF (45seconds maybe) but runs like fecal matter the whole time

I have swapped out the MAF, EGR valve and IAC valve with parts from a 97 century (which runs fine)And nothing seemed to change the condition.

Changed fuel filterchecked fuel pressure with key on (41psi)Also replaced the timing chain and gears (thinking it slipped) but it didnt make a difference.

I pulled codes but all it had was a P0102 (MAF low input)But I think that might be from it being unplugged so many times?

Ford Super Duty (1999-2016) :: Heater Blowing Cold Then Truck Overheated And Pushing Coolant Out Of Cap

My '01 Super Duty 5.4 has an overheating/heater problem that the dealer can't seem to fix. I noticed my heater was blowing cold then a few miles later it overheated pushing coolant out of cap. Next day drove fine to Ford dealer who replaced my heater core, thermostat, reservoir cap and a hose. Drove it for a day till the exact original symptoms occurred again with a gurgling sound in dash. Dealer kept for a week pressurizing system but no leaks found. Replaced my thermostat again and gave it back. I drove it 300 miles over a week before the exact same symptoms occurred. Brought back to dealer who said that air was in the system, added a bunch of coolant and supposedly got all the air out. Same symptoms still. Brought back to dealer that finally changed the water pump they said had a leak. Guess what, same symptoms. Heater will work fine for days then it will blow cold, then hot, then cold and sooner or later truck will overheat then just as fast cool down and heater will work again. Still hearing gurgling. Dealer said I don't have a HCV.

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.

Century :: 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?

Buick - 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?

Buick - Century :: 2002 Turns Over And Over But Does Not Start

Most of the time it has no problem what-so-ever, but once in a while it just doesn't start. It will turn over and over but that's it. Most of the time if I just let it sit for a few minutes (5-20) it will start right up no problem, but I've noticed when it does it often revs up as if I had my foot on the gas. (that took me a while to realize since I often touch the gas anyway.) Once it's running it runs great. The idle settles down to normal after a few seconds and the car runs as if there was no issue. It does this randomly.

I can drive it for days or hours with no problem, and then suddenly it just decides to leave me stranded. Usually i wait and it gets me home, but a couple times it didn't. I've drained the battery twice on two different occasions months apart trying it, and waiting and trying it. Both times with barely enough juice the following day to turn it over, it fired right up, rev'd the engine, then ran fine. I don't think it's an issue with fuel because on one occasion while trying to start it I laid into the peddle until I could smell gas under the hood- and it never has issue while running, only on start-up.

So far the only thing I've done is replace the spark plugs- it runs better now, but doesn't start any differently.

Buick - Century :: Squealing In Front Of Transmission?

So I have squealing in the front of the transmission under hard acceleration. It also happens when I rev the engine while in Park. Could it be in the transmission or would just replacing the torque converter work? This is an 01 buick century with 150k miles.
