Aug 2, 1996
OIL MIST CONTAINED IN THE ENGINE INTAKE AIR CAN COLLECT OVER TIME IN THE BRAKE VACUUM CHECK VALVE PREVENTING THE CHECK VALVE FROM OPENING AT THE SPECIFIED PRESSURE REDUCING POWER ASSIST TO THE BRAKES.
Consequence & remedy
Consequence: BRAKE PERFORMANCE CAN BE DIMINISHED INCREASING THE RISK OF A VEHICLE ACCIDENT.
Remedy: DEALERS WILL REPLACE TWO VACUUM HOSES, INCLUDING THE CHECK VALVE, WITH MODIFIED HOSES.
95V069000 · Fuel System, Gasoline:delivery:hoses, Lines/piping, And Fittings
Mar 30, 1995
RESIDUAL ENGINE HEAT CAN CAUSE PREMATURE DETERIORATION OF THE FUEL HOSE CAUSING THE HOSE TO LEAK. ALSO, REMOVING AND REINSTALLING THE DETERIORATED FUEL HOSES INCREASES THE LIKELIHOOD OF A LEAK.
Consequence & remedy
Consequence: THIS CONDITION CAN RESULT IN AN ENGINE COMPARTMENT FIRE.
Remedy: DEALERS WILL INSTALL AN ADDITIONAL CONTROL UNIT FOR THE ELECTRIC COOLING FAN. THE FAN WILL THEN ACTIVATE AFTER THE ENGINE IS TURNED OFF WHEN THE COOLANT EXCEEDS A SPECIFIED TEMPERATURE. THE FUEL HOSES WILL ALSO BE REPLACED WITH REVISED HOSES.
94V094000 · Engine And Engine Cooling:cooling System
May 11, 1994
THE RADIATOR CAP PRESSURE RELIEF VALVE RELEASE PRESSURE IS SET TOO HIGH. THIS CAN CAUSE THE COOLANT TO REACH TEMPERATURES THAT EXCEED THE THERMAL DESIGN LIMITS OF SOME COMPONENTS OF THE COOLANT SYSTEM. SHOULD THIS OCCUR, ENGINE COOLANT CAN LEAK COLLECT ON TOP OF THE ENGINE.
Consequence & remedy
Consequence: IF ENGINE COOLANT LEAKS ONTO THE HOT ENGINE EXHAUST MANIFOLD FROM THE TOP OF THE ENGINE, AN ENGINE COMPARTMENT FIRE CAN RESULT.
Remedy: 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. IN ADDITION, ALL VEHICLES IN WHICH THOSE COMPONENTS ARE REPLACED WOULD ALSO HAVE THE COOLING SYSTEM AND OTHER SYSTEMS THAT CARRY FLAMMABLE LIQUIDS CHECKED TO MAKE CERTAIN THAT ENGINE OVERHEATING HAD NOT CAUSED ANY PROBLEMS IN THOSE SYSTEMS. ANY IDENTIFIED PROBLEMS WILL BE REPAIRED. THE RADIATOR CAP, FILLER CAP, AND FILLER CAP BODY OF ALL RECALLED VEHICLES WILL BE REPLACED BY NEWLY DESIGNED PARTS.
