Known issues on the 1989 Eldorado. Two recalls are on federal record for this model year. The first covers the gasoline fuel system: a replacement fuel filter connector that was not manufactured to spec can leave the O-ring improperly seated at the connection, and an inadequate seal there can lead to a fuel leak that, near an ignition source, could start a fire. The second covers the antilock service brakes: one or both ABS hydraulic unit mounting bolts may not be properly seated and can loosen, which can let the ABS hydraulic unit separate from its mounting bracket and cause a sudden loss of brake function and a crash without warning. Owners have filed 10 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind both of those systems are here.
From a fuel line and filter connection check to an ABS mounting inspection or routine service, it keeps you on the correct factory procedure for your specific 1989 Eldorado.
ONE OR BOTH ABS HYDRAULIC UNIT MOUNTING BOLTS MAY NOT BE PROPERLY SEATED AND COULD LOOSEN.
