2005 Buick Century Problems

Intake Manifold Gasket 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.

Poor Ride/Handling Due to Worn Suspension Struts

The front struts may show signs of wear, or be excessively bouncy ride at freeway speeds. This may begin to occur at around 75,000 miles.

Check Engine Light Due to Gas Cap Issue

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

How much should a timing cover gasket replacement cost? (1 answer)

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?

2005 Buick Century Reviews

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