A faulty alternator in your Saturn can cause a whole host of symptoms. Most of the systems on this car are computer-controlled and require a minimum of 12.7 volts to operate properly.The standard engine package found in a Saturn is the 1.9 liter DOHC motor. The alternator in this vehicle is located low in the engine compartment and, as a result, is a difficult alternator to replace. The average weekend mechanic should be able to complete this repair in about two hours using basic hand tools.
