Buick Century Problems

Intake Manifold Gasket May Leak Coolant or Engine Oil

Engine -- Verified

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine  with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

High Pressure Power Steering Hose Can Leak Fluid

Suspension & Steering -- Verified

The high pressure power steering hose will commonly leak fluid; it should be replaced.

Coolant Leak & Engine Overheating

Engine -- Verified

A coolant leak may develop from the water pump. The engine may overheat as a result of the coolant loss. A leaking water pump should be replaced.
 

Corrosion At Ignition Coil Towers

Corrosion may develop at the connection between the ignition coil tower and spark plug wire resulting in an engine misfire. The Ignition coil and spark plug wire should both be replaced to correct this condition.

Oil Pump Drive O-ring May Leak Oil From Rear of Engine

Engine -- Verified

An engine oil leak may develop from the rear of the engine. This is commonly caused by a failed oil pump drive o-ring seal. The leaking o-ring should be replaced to correct this concern.

Buick Century Stories

Where should I start? I'm 17, and this is my second car (my first was a Shovette lol). I found this car early in March of 2011. It was an old hunk of junk in some lady's barn. It was hers but the water pump went out and then she just used it to store hay and feed the horses from the trunk. I got it for $50, towed it home and slapped a water pump in it and it has been running since. I got it at only 69k miles. The paint is rusted and that's it, the inside is in perfect condition but there is still a little hay in the trunk. This car is big and a lot faster than one would think. If you press the gas, it WILL move. Taking corners is a little thick and lumbering but its fine. The engine is huge and has plenty of power with very little road noise. This thing will run with anything you throw at it, I've taken it on a few road trips and its perfectly great. Its ready to start as soon as you touch the key in the ignition. This thing is a beast, not to mention so comfy to ride in. I'm a Buick buyer for life now.

What would make a 2005 Buick Century leak gas out on the carburator intake every now and then?

I have over 315,000 miles on the original engine, and it seems to keep going strong. I have noticed just in the past couple weeks its been taking a little longer to start-up. I did have to have the exhaust manifold gasket changed cause it was leaking coolant in and out the engine. Two of the windows no longer roll up or down, the Check Oil light is forever on, as is the Low Coolant, and Service Engine Soon lights, and I also no longer have working Hi-beams. Also, the A/C comes on when it feels like it and goes off when it feels like it, so I tend to just drive with it on so as not to constantly hear the switching. And the light to be able to read the gauges at night doesn't work, or sometimes does work but it's very rare when it does and goes off just as mysteriously as it turned on.

the car is in excellent condition and very low milage about what would this car sell for

I bought my 90 Buick Century about 6 months ago. It passed hands many many times and was not well maintained. It was in 2 accidents before I owned it and when I bought it I was mostly just crossing my fingers that it would last more than a month. The odometer read 100k when it got to me but the instrument cluster was broken so god only knows when that stopped working. It seemed like a project car but I was pleasantly surprised. since I replaced the instr. cluster I've added just shy of 20k miles, taken it cross country and back twice, and only done very minor repairs. The water pump went, but that was only about an hours work to replace, and now my power windows are out. I plan to keep this car until it's final day, whenever that may be, and after driving Mazdas and Chryslers and Fords, I will only own Buicks from now on.
