2001 Saturn SC2 Problems
RepairPal has identified the most common problems with the 2001 Saturn SC2 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
Owners may notice the warning message "A/C off for Engine Protection" displayed on their instrument panel, 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.
An automatic transmission fluid leak may develop from the rubber section of a transmission cooler line. In some cases the rubber section of hose can be replaced. In others, the complete cooler line must be replaced to correct this type of leak.
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
The spark plugs should be replaced every 30,000 miles and the spark plug boots should be checked for hot spots and cracks.
The timing chain may come into contact with the timing cover, causing noise in the engine. Replacement of worn timing chain components will be necessary to correct this concern.
The alternator may fail causing the charge light to illuminate. Driving with this condition will eventually cause the engine to stall due to low system voltage.
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.
