Known issues on the 1988 5000. Three recalls are on federal record for this model year. The first covers the transaxle: differential oil is lost over time to evaporation, and low fluid causes premature bearing and gear wear that can lead to differential failure, with the drive wheels losing power or the front wheels locking and causing rapid deceleration. The second covers the fuel tank: repeated topping off during refueling reduces expansion space and lets vapors escape from the charcoal filter to the outside rather than into the engine, where escaping vapors could be ignited by heat from the exhaust system. The third covers the fuel injection system: seals can harden from high temperature and alcohol content in some fuels and allow fuel to escape into the engine compartment, where dripping onto hot components could start a fire. Owners have filed 1 complaint for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind each of those systems are here.
From a differential fluid check to a fuel tank or injection seal inspection, it keeps you on the OEM procedure and the correct specification for your specific 1988 5000.
THE DIFFERENTIAL OIL OF THE TRANSAXLE IS LOST OVER TIME DUE TO EVAPORATION. LOW OIL LEVELS CAUSE PREMATURE BEARING AND GEAR WEAR AND EVENTUAL FAILURE OF THE DIFFERENTIAL.
IN THE EVENT OF FAILURE, THE VEHICLE'S DRIVE WHEELS COULDLOSE POWER. IN EXTREME CIRCUMSTANCES, THE FRONT WHEELS LOCK, CAUSING RAPIDDECELERATION RESULTING IN POSSIBLE LOSS OF VEHICLE CONTROL AND AN ACC
DRAIN AND REPLACE THE DIFFERENTIAL GEAR OIL WITH OIL HAVING HIGHER PERFORMANCE CHARACTERISTICS.
REPEATED TOPPING OFF OF FUEL TANK DURING REFUELING REDUCES THE EXPANSION SPACE WITHIN THE TANK ALLOWING VAPORS TO ESCAPE FROM THE CHARCOAL FILTER TO OUTSIDE RATHER THAN BEING INDUCTED INTO THE ENGINE.
ESCAPING VAPORS COULD IGNITE BY HEAT EMITTED BY THEEXHAUST SYSTEM.
INSTALL REDESIGNED FILLER NECK AND A NEW VENT VALVE AND HOSE FOR CHARCOAL FILTER. ALSO, STOP REFUELING WHEN PUMP NOZZLE SHUTS OFF.
FUEL INJECTION SEALS MAY HARDEN, DUE TO HIGH TEMPERATURE AND ALCOHOL IN SOME FUELS, AND ALLOW FUEL TO ESCAPE INTO THE ENGINE COMPARTMENT.
FUEL DRIPPING ONTO HOT ENGINE COMPONENTS COULD CAUSE ANENGINE COMPARTMENT FIRE.
REPLACE ENGINES FUEL INJECTOR SEALS WITH IMPROVED SEALS PLUS IMPROVEMENTS DESIGNED TO BETTER INSULATE THE ENGINE AGAINST FIRE RISK.
A SMELL OF GAS AROSE, PARKED THE VEHICLE AND LOOKED BACK AT THE VEHICLE, A FIRE STARTED IN THE GRILL IN THE FRONT OF THE VEHICLE. PLEASE PROVIDE FURTHER INFORMATION. *AK
