SUBJECT: CRACKED EVAPORATOR BLOCK FITTING

MODELS AFFECTED: 1987 DEVILLE, FLEETWOOD, SEVILLE, ELDORADO AND ALLANTE

Figure 1 - Evaporator Block Fitting Bolt:

Some 1987 DeVilles, Fleetwoods, Sevilles, Eldorados and Allantes may experience evaporator block fitting cracking. This condition may be caused by over torquing the evaporator block fitting bolt. It is extremely important not to exceed the 17 N-m (12 ft.lbs.) torque specification when tightening the evaporator block fitting bolt. Excessive torque may crack the block fitting necessitating replacement of the evaporator core.
