Known issues on the 1993 Eldorado. Two recalls are on federal record for this model year. The first covers the fuel feed and return lines to the engine fuel injection system, which were not fully assembled and locked and can work loose, causing a fuel leak in the engine compartment that risks an underhood fire near any ignition source. The second covers the air conditioner compressor clutch assembly, which can rub through the auxiliary engine oil cooler outlet hose, leaking engine oil onto the hot exhaust system and risking an engine compartment fire. Owners have filed 48 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 tracing a fuel line leak to inspecting the A/C compressor clutch clearance or a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 1993 Eldorado.
