SERVICE ENGINE ASSEMBLIES
MODELS AFFECTED:
1985-1991 DE VILLES AND FLEETWOODS

This bulletin supersedes T-89-15 which should be discarded. This bulletin is being revised to include subsequent model years and update some part numbers.
The following is a list of 4.1L, 4.5L, and 4.9L V-8 service engine assemblies currently available from GMSPO to accommodate 1982-1991 Cadillacs. Past model service engines have been produced or remanufactured subsequent to the model year of the vehicle; and as such, incorporate refinements not considered in contemporary service information (i.e., 1982 engines may incorporate features normally associated with 1987 models). If future service is necessary, Service Builetins filed in Group 6A should be consulted to clarify the service procedures necessary to accommodate these revisions.
Longitudinal engine assemblies are remanufactured for General Motors to Cadillac specifications. Transverse engine assemblies are produced using new parts.

4. Dipstick Consideration
^ Longitudinal service engine assemblies, 12336132 through 12336137, are not supplied with a new dipstick. The original parts must be transferred. See chart below for revised applications.
^ Part numbers 3635194 and 3635195 are equipped with a dipstick calibrated for 1986 DeVilles after VIN 4252323 and 1987 DeVilles respectively.
- If 3635195 is installed in a 1987 Eldorado or Seville, transfer the dipstick from the replaced engine (1640020).
- If 3635194 is installed in a 1986 Eldorado or Seville, transfer the dipstick from the replaced engine (1640020).
- If 3635194 is installed in a 1985 or a 1986 DeVille before VIN 4252323, install dipstick 1629282.
^ Assembly 3635196 is equipped with a dipstick calibrated for 1988-1989 DeVilles.
- If 3635196 is installed in a 1988-1989 Eldorado or Seville, transfer the dipstick and tube from the replaced engine.
