Number 20
Corp. Ref. No. 816201
Date June '88
SUBJECT: SEIZED ACCESSORY DRIVE COMPONENTS AFFECT ON SERPENTINE DRIVE BELT
MODELS AFFECTED: 1985-1988 DE VILLES AND FLEETWOODS 1986-1988 ELDORADOS AND SEVILLES 1987-1988 ALLANTES
Some 1985-1988 DeVilles and Fleetwoods, 1986-1988 Eldorados and Sevilles, and 1987-1988 Allantes may exhibit a condition of a seized engine driven accessory (such as A/C compressor, generator, power steering pump, etc.) which causes the drive pulley to stop rotating. The serpentine drive belt should be replaced regardless of whether or not it exhibits evidence of chunking described in Serviceman Bulletin T-87-145, Group 6B. The heat generated by the belt attempting to rotate a seized component will overheat the rubber to the extent belt breakage or excessive wear may eventually occur.
