Modifying Radiator Fan Shrouds Issue: 02/90-1214
Application:
1979-89 900 Models Fitted With Replacement Radiators
In late-1989 900 production a running change was made to an improved radiator design with plastic tanks and an aluminum core. This change took place
at VINs K3022369- and K7030345-. This radiator design has now been introduced into the spare parts system and is the only available 900 replacement
radiator.
When an aluminum core radiator is installed on an earlier car, minor modifications must be made to the plastic radiator fan shrouds. These modifications
are necessary because the larger seam between the plastic side tanks and the aluminum core interferes with the fan shrouds.

RH Fan Shroud (Naturally Aspirated):
The RH fan shroud installed on naturally-aspirated 900s up to mid-1989, P/N 83 19 931, must be modified as shown below. In spare parts supply, this
fan shroud has been superseded to a later version, P/N 40 27 777, which does not require modifications.
To modify the RH fan shroud (P/N 83 19 931), use a hack saw or a cut off wheel to remove the flange on the RH side (See Figure 1). You must also
notch a 10 mm X 10 mm section out of each end of the curved section of the shroud (Figure 1).
Check the fit of the fan shroud on the radiator prior to mounting the radiator in the car. Trim as necessary to ensure sufficient clearance with the radiator
tank seam.
