Corrective Action:
DEALERS WILL INSPECT THE VEHICLES AND IF ANY VEHICLE EXHIBITS COOLANT LEAKAGE OR IF THE COOLANT LEVEL HAS DROPPED TO THE POINT WHERE THE COOLANT LOSS WOULD BE SUFFICIENT TO TRIGGER THE COOLANT LEVEL WARNING SYSTEM, COMPONENTS POTENTIALLY SUBJECT TO DETERIORATION FROM OVERHEATING WOULD BE REPLACED. THESE PARTS INCLUDE THE WATER PUMP BEARING HOUSING, THE WATER LEVEL SENSOR AND RADIATOR UPPER HOSE, THE THERMOSTAT GASKET, AND ALL WATER HOSES LOCATED ABOVE THE ENGINE.
