393V015000 · Visibility:defroster/defogger/hvac System:heater Core
Feb 1, 1993
THE MALFUNCTION OR FAILURE OF A COOLANT SYSTEM COMPONENT RESULTS IN SIGNIFICANTLY INCREASED COOLANT TEMPERATURE AND A RESULTING INCREASE IN SYSTEM PRESSURE.
Consequence & remedy
Consequence: VEHICLES OPERATED UNDER THIS INCREASED COOLING SYSTEMPRESSURE CONDITION CAN SUFFER DAMAGE OR FAILURE OF PARTS OF THE COOLING SYSTEMSUCH AS (1) LEAKAGE FROM A COOLANT HOSE, (2) LEAKAGE OF THE RADIATOR OREXPANSION TANK, (3) DISCONNECTION OF A HOSE FROM A PIPE OR A FITTING, AND (4)CRACKS IN THE HEATER CORE END PIECE RESULTING IN COOLANT LEAKAGE. IN SOME CASES,BOILING COOLANT CAN CONTACT THE LOWER RIGHT LEG OF THE DRIVER RESULTING INBURNS. ALSO, ESCAPING COOLANT IN THE PASSENGER COMPARTMENT CAN CAUSE VAPORFOGGING OF THE INTERIOR SURFACE OF THE WINDOWS, REDUCING DRIVER VISIBILITY.
Remedy: DEALERS WILL INSTALL A THERMOSTATIC BYPASS VALVE IN THE ENGINE COMPARTMENT TO CONTROL COOLANT TEMPERATURE IN THE HEATER CORE. ALSO, A NEW DESIGN RADIATOR CAP WILL BE INSTALLED, TO CONTROL PRESSURE AND PROVIDE GREATER COOLANT OVERFLOW IN THE EVENT OF OVERHEATING.
85V058000 · Fuel System, Gasoline:carburetor System
May 6, 1985
THE IDLE CONTROL VALVE WHICH CONTROLS IDLE SPEED BY VARYING THE AMOUNT OF INTAKE AIR THAT BYPASSES THE THROTTLE PLATE IS SUBJECT TO BACKFIRE INTO THE INTAKE MANIFOLD. SUCH BACKFIRE CAN DAMAGE THE VALVE AND CAUSE THE IDLE VALVE PLATE TO REMAIN OPEN. CONSEQUENCE OF DEFECT: THIS WILL RESULT IN ABNORMALLY HIGH IDLE SPEED.
Consequence & remedy
Consequence: Not supplied
Remedy: INSTALL A REDESIGNED IDLE CONTROL VALVE WHICH CAN NOT STICK OPEN.
84V107000 · Visibility:defroster/defogger/hvac System:windshield:electrical Heating Element
Sep 11, 1984
WATER CONTROL VALVE IN THE HEATING SYSTEM MAY NOT CLOSE COMPLETELY. EXCESSIVE CURRENT MAY BEGIN TO FLOW THROUGH THE WIRING TO THE CONTROL VALVE RESULTING IN OVERHEATING OF THE WIRING.
Consequence & remedy
Consequence: Not supplied
Remedy: WIRING TO THE VALVE WILL BE REPLACED WITH A WIRE CONNECTOR THAT HAS A FUSE. THE FUSE WILL PREVENT THE OCCURENCE OF AN ELECTRICAL OVERLOAD.
