RIGHT COOLING FAN STALL REPL. FAN/ADD UNDERBODY SCREEN

SUBJECT: RIGHT COOLING FAN STALL (REPLACE COOLING FAN AND ADD AN UNDERBODY SCREEN)

VEHICLES AFFECTED: 1990-92 OLDSMOBILE TORONADO

Some 1990-1992 Oldsmobile Toronados prior to VIN breakpoint NU304238 may experience a stalling condition of the right cooling fan. This may be due to an ingestion of road debris by the fan motor. The aerodynamics of this vehicle allows ram air to be picked up from the road, which may be littered with plastic bags and wrappers. To prevent this condition, replace the damaged cooling fan, if necessary, and add an underbody screen which has been developed to protect the fan from ingesting road debris.
