Known Problems

The Saturn LW300 may display the warning message "A/C off for Engine Protection" on the instrument panel. This may be accompanied by illumination of the check engine light and the temperature gauge reading cold at all times. This is a feature of the engine that is activated by the power control module when it detects the engine warming up too slowly. The OBD trouble code P0128 may also be stored. 

The cause is simply a worn out thermostat that stays open at all times, preventing the engine from reaching the proper operating temperature. 

Replacement of the thermostat will correct the issue. 

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

A burning smell may develop due to an oil leak form one or both valve cover gaskets. Resealing the valve cover will generally correct this concern. However, the valve covers should be inspected and replaced if damaged.

GM recommends replacing the engine coolant at 100,000 miles; however, our technicians tell us that the coolant may become contaminated and require a complete cooling system flush every 60,000 to 70,000 miles.

Brake fluid can become dirty and may cause problems in the brake system; it should be flushed every 60,000 miles.
