#324 of 482 Buick Century: Intake Manifold Gasket/Coolant Leak
Jan 23, 2004 (5:01 pm)
Hi everyone! My 2000 Buick Century has developed a coolant leak at 114,000 kilometers Mechanic (non-dealer) says that intake manifold gasket must be replaced (and hopefully nothing more). GM put out a Technical Service Bulletin in March, 2003 for this problem recommending that "a new design intake manifold gasket" (different gasket material) be installed to replace leaky gasket. Has anyone been successful in getting GM to do repairs under warranty? Any suggestions would be appreciated.

I too have a 3.1 litre In My 1999 Chevrolet
Malibu. This Car has had the Intake Manifold
Gasket repaired TWICE ! First Time At 71,000 Km
Second time at 109,000. The mechanic at my
Toronto Ont. area dealership told me GM is using
an improved Gasket material that should improve
the longevity. (HMMM) As far as GM Replacing it,
unless you have an extended warranty (I DO on
my Malibu) I doubt they will, seeing as you're
past the 3 YR/ 60,000 Km Factory Warranty. If you
pressure your dealership you never know. As far
as cost of repair goes i've heard everything
from $500.00 at a local garage to $1000.00 at
the Dealer, so get some estimates Sadly, this is
a known flaw on GM 3.1 litre Engines. Take a look
On the Chevy Malibu Forum almost everyone has had
this problem. Hope this is helpful. Good Luck
with Your Car. We are thinking of buying a Century
Had one as a rental when the Bu was in the shop. Is it a good
everyday Car ? Reliable ? Only had it for an overnight so it was
kinda hard to tell.First impression was good. smooth ride and very
quiet interior. Any Thoughts ??
#328 of 482 Advice needed, help plz.

Hey, guys,I am looking into a 00'Buick Century Custom at 75K miles. The price is $5100 for Zip code 14623. It was a leased car before. Very nice in and out. Is it a good deal at all?
One more thing is that I notice the power window only works at the master controller. I read something in this forum and found this might be a persistent problem, is it true? Also, for a car at this high mileage, when would I expect to throw money in for major repair. Please give your opinion and thanks very much.

Has anyone changed out the air filter in their 3.1L V6 lately? How do you get the cover off without breaking something?! Thanks.

Disconnect the duct at both ends.
Disconnect first the two connector at the map sensor, pull out the plastic pipe from the duct also.not more than 20 mn
#331 of 482 Thanks, baveux!

Many thanks baveus. Air filter job done. Needed some encouragement, and your words did the trick.
Getting rubber duct off was troublesome. Before your post I tried removing it from end where air filter element box is. Nope.
After disconnecting sensor wires (putting them in safe out of the way place) and PCV, and loosening the strap screws at both ends, wrapped both hands around end of duct at engine end, then gave it a short twist to bust it loose. Grabbed the accordian part of the duct and gave it a good healthy pull to remove it from the engine. From there it was pretty easy.
This is my son's car. Just got it. '03 rental return (Hertz). Considerate Dad is changing out oil, oil filter, air filter and cabin filter.
Here's the scary part. When engine was stone cold, removed radiator cap and found orangish-yellowish crud at the top of the filler neck. Vehicle only has 23,400 miles on it. Recovery tank was at the FULL mark as expected, but the coolant was about 3/4 inch below the top of the filler neck.
Took it to Jiffy Lube and for $92 US (with AAA discount) they power flushed the system with new Dex-cool. But wonder: is it too late? Is the crud everywhere in the radiator, water pump, engine sleeves? There's still 11k+ miles left on warranty, but wonder what GM would do about it.

I doubt that the stuff describe is crud.It's probably the stop leak that GM put at the factory.
I had some of that stuff in my Pontiac Montana recovery thanks. That stuff looked like saw dust paste.
I doubt that the cooling system is contaminated at such low milleage, but hey, its hard to tell from here !!
#333 of 482 Test Driving a 2003 Buick Century Custom
Feb 16, 2004 (5:04 pm)
We are currently test driving a 2003 Buick Century Custom. It has 17,000 miles on it and they want around $11,500 for it --- does that sound reasonable? They also have a 2003 Buick with 29,000 miles on it and they want $9,995 for it, that seems like a lot of miles for only being one year old. They also call it a program car. What is that? Please help.
