2002 Saturn SL Problems
RepairPal has identified the most common problems with the 2002 Saturn SL based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
Saturn SL 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.
The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.
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 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 rubber section of an automatic transmission cooler line may develop a fluid leak . In some cases the leaking section of hose can be replaced. In others, the complete cooler line must be replaced to correct this concern.
