2004 Buick Century Problems

Intake Manifold Gaskets May Leak Coolant or Engine Oil

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.

Power Window Switch May Fail

One or more power window switch may fail. The affected window may work intermittently before failing completely.

Transmission Pressure Control Solenoid Failure May Cause Erratic Shifting

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.
