1991 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 door window may move slowly or stop in mid travel due to a failing power window motor. The affected window may start working again after the motor cools off. Replacing the faulty window motor will commonly correct this concern.

The inside door handle may break causing the door not to open from the inside.

An excellent car for those who like to explore while being comfortable. Also great as a commuter vehicle because of the fact that one has plenty of legroom and trunk space is not limited.
