1983 FORD E350 recalls

HEATER HOSE MAY BE INCORRECTLY ROUTED.

HOSE COULD WEAR THROUGH AND LEAK WHICH COULD RESULT INAN UNDERHOOD FIRE.

REROUTE AND REPAIR HOSE AS NECESSARY.

EXTREME OPERATING CONDITIONS COULD CAUSE PREMATURE DETERIORATION OF THE ENGINE COMPARTMENT HEATER HOSES OR ENGINE BYPASS HOSES.

ENGINE COOLANT COULD DISCHARGE ONTO THE ENGINE AND ITSEXHAUST MANIFOLD CREATING THE POTENTIAL FOR A FIRE DUE TO THE HIGH ENGINEEXHAUST MANIFOLD TEMPERATURES.

REPLACE HOSES AND RADIATOR CAPS; INSTALL HIGH HEAT RESISTANCE ALUMINIZED STAINLESS STEEL MUFFLERS.

WHEN FRONTALLY IMPACTED INTO A FIXED BARRIER AT 30 MPH, AS SPECIFIED IN FEDERAL MOTOR VEHICLE SAFETY STANDARD (FMVSS) NO. 301, THE LEFT FRAME RAILS OF SUCH VEHICLES MAY DISPLACE INBOARD, PINCHING THE FUEL/WATER SEPARATOR CANISTER BETWEEN THE FRAME RAIL AND ENGINE SUFFICIENTLY TO DISPLACE THE FUEL/WATER SEPARATOR DRAIN ROD, ALLOWING THE CONTENTS OF THE CANISTER TO DRAIN. CONSEQUENCE OF DEFECT: FUEL LEAK DURING OR AFTER A CRASH INCREASES THE POSSIBILITY OF A FIRE.

INSTALL A CANISTER SHIELD, A REVISED DESIGN DRAIN ROD SHIELD, AND MODIFY FUEL/WATER SEPARATOR MOUNTING BRACKET.

VEHICLES ARE SUBJECT TO EXCESSIVE UNDERHOOD TEMPERATURES AND FUEL SYSTEM PRESSURES IN SEVERE DUTY APPLICATIONS.

THIS CREATES POTENTIAL FOR FUEL EXPULSION FROM THE FUELFILLER PIPE WHICH IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN AFIRE.

INSTALL MODIFICATION KITS TO MINIMIZE POSSIBILITY OF FUEL EXPULSION AND TO SHIELD UNDERBODY COMPONENTS FROM EXHAUST SYSTEM HEAT.

SOME OF THE INVOLVED VEHICLES MAY HAVE A DIODE IN THE ELECTRICAL FUEL PUMP CIRCUIT THAT MAY SHORT DURING ENGINE STARTING DUE TO INADEQUATE CAPACITY TO WITHSTAND CURRENT DRAW. A SHORT CIRCUIT WOULD RESULT IN NORMAL ENGINE STARTING, BUT THE PUMP WILL NOT CONTINUE TO SUPPLY THE ENGINE WITH FUEL.

THE DEALER WILL REPLACE DEFECTIVE ELEMENT IN THE ELECTRICAL FUEL PUMP CIRCUIT WITH A NEW RELAY FEED WIRING ASSEMBLY WHICH CONTAINS A LARGER CAPACITY DIODE, FREE OF CHARGE.

ON CERTAIN VEHICLES, THE LOCK WEDGES USED TO SECURE THE AXLE BEARING NUTS TO THE AXLE HOUSING MAY FALL OUT OF POSITION, ALLOWING THE NUT TO LOOSEN. THE NUT ON THE LEFT SIDE MAY FALL OFF, ALLOWING MOVEMENT OF THE AXLE SHAFT.

THE DEALER WILL REPLACE DEFECTIVE LOCK WEDGES WITH AN IMPROVED VERSION. WHEEL BEARINGS WILL BE INSPECTED AND ADJUSTED OR REPLACED, IF NECESSARY.

ATTACHING BOLTS ON FUEL TANK SUPPORTS MAY NOT HAVE BEEN ADEQUATELY TIGHTENED; ALSO, THE SUPPORTS ARE TOO THIN. HIGH LEVELS OF STRESS, WHICH COULD OCCUR UNDER NORMAL OPERATING CONDITIONS, COULD CAUSE CRACKS TO DEVELOP IN THE SUPPORT STRAPS. IF THE FUEL TANK SUPPORTS FRACTURE, THE FUEL TANK WILL SLIP FROM THE NORMAL POSITION, AND FUEL LEAKAGE COULD RESULT.

FUEL TANK SUPPORTS AND FASTENERS WILL BE REPLACED WITHOUT CHARGE.

EXPULSION OF FUEL DUE TO OVERPRESSURIZATION.

FUEL OR FUEL VAPORS IN THE PRESENCE OF AN IGNITIONSOURCE CAN CAUSE A FIRE.

MODIFICATION OF THE BASE FUEL VENTING AND EMISSION CONTROL SYSTEM TO REDUCE OPERATING TEMPERATURES AND FUEL SYSTEM PRESSURES.
