2003 Buick Century Problems
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.
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.

Great car now at 130,000 with still no oil leaks! Did have to replace water pump at around 100k. The air conditioning in these cars is amazing!!!
What can I say! I have driven a Volvo, several Fords and a Toyota and none of these vehicle compare favorably with my Buick. At over 300K miles (this is not a mistake) and counting, I have only had work done on the radiator recently. Outside of the normal wear such as brakes and some window issues, I have had no problems with this car. I intend to get another Buick Century.
