Known issues on the 1993 DeVille. One recall is on federal record for this model year, covering the axle assembly: the upper transaxle oil cooler hose can pull out of its crimped coupling at the transaxle end of the line assembly, and if the coupling separates, the resulting oil leak can reach an ignition source and start an engine compartment fire. Owners have filed 120 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind that system are here.
From inspecting the transaxle oil cooler line to a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 1993 DeVille.
THE UPPER TRANSAXLE OIL COOLER HOSE CAN PULL OUT OF THE CRIMPED COUPLING AT THE TRANSAXLE END OF THE LINE ASSEMBLY.
IN THE EVENT OF SEPARATION OF THE COUPLING, AN OIL LEAK CAN OCCUR WHICH, WHEN EXPOSED TO AN IGNITION
DEALERS WILL INSTALL A NEW UPPER TRANSAXLE OIL COOLER LINE TO THE TRANSAXLE.
