2005 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.

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

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.

2005 Buick Century Questions

Had an oil leak so we had the oil pan gaskets replaced. Leak persisted. The timing cover gasket is now to blame and replacement for that and a water pump and a coolant kit and service is costing just under $600. Is that reasonable?

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

Thje car has given good service. The major problem is the driver A/C does not throw out cold air but the passenger side does. We have not got a good answer from the repair shop.

At over 101,000 I still love my fancy-goldie. This is absolutely the BEST car I have ever had and I am sorry they stopped making the Century. I replaced her brakes and rotors at about 85,000. I have had some slowness starting in the electric window rolling down on the passenger side. She has a little bit of a clack of the engine while in park - but dealer said that was normal and nothin...
