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.

2002 Buick Century Problems
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.
The high pressure power steering hose will commonly leak fluid; it should be replaced.
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.
The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

2002 Buick Century Reviews
I bought this low mileage one owner car as a work car. This was my 6th Buick. Between the rocker panel rust, window motor replacements, and errant engine light problems, within a year I sold it. I will never buy a Buick, or any other GM car again!
Just bought a 2002 Century used. 60,000 miles. Like the car so far for ride and feel. Just changed the oil and filter and that turned out to be more of a pain than I'm used to. Attempted the air filter and the replacement didn't seem to match up with the owners manual. Finally gave up and will take to the shop. Hopefully all of the "basic" maintenance isn't this difficult
I absolutely love my Century... it has been a wonderful car with very little repairs, other than normal wear and tear... I'm pushing 150,000 miles and can't complain. Still get 22-25 mpg around town and the car continues to run well.
Excellent choice for someone looking for a reliable vehicle!
Bought this well maintained car (all service records present at the time of sale) with 69,000 miles on it in a private sale from the original owner in 2006. It has been virtually trouble free to 125,000 miles.
I just had 120,000 mile service done which included draining and flushing the transmission. Watch out for high prices here. Big variance from 100 bucks to near 300 bucks .... check your local GM dealerships and ask what they are charging by make and model year. There is a difference between "drain" and "drain and flush." Parts prices vary widely. I've heard comments from don't need the drain and flush to yes you do .... I tend to think it should be done, especially if fluid is not bright red (mine wasn't .... dull but not brown) b/c I drive cars to 250K, have been very particular about doing the recommended maintenance and it has served me well. Just use this site to get a good idea of costs and then compare prices and go where you can get a good price and reputable service.
I can recommend this car as a very good value if you can find a 2002 Century Custom with less than 110,000 on it. After 2002, GM dropped some of the features on this body style and had some other engineering changes that make the 2003 and on versions less desireable.
has not cost a lot in 7 years. replaced exhaust gasket was 700.00 tires & baterys
