DI Diesel Engines M57/M67 - Common Rail Sec. 6 P.7
Course contents/Background material
Exhaust hood/shutter
No radiator shutters are currently installed in the M57 and M67.
Fan
The M57 and M67 feature a 7-blade plastic fan driven by a
viscous clutch. Compared to an electric fan, the viscous fan
provides better cooling capacity.
In addition to the viscous fan, an electric fan that is activated by
the DDE is arranged in front of the radiator assembly.
Auxiliary heater
An auxiliary heater with connection to the heating circuit is
installed as standard in the M57 E38/E39 and in the M67 E38
(as
on the M47). It is installed instead of the independent park
heating in the vehicle.
The separate auxiliary heater is dropped if the independent park
heating option is installed. The independent park heating then
assumes the function of the auxiliary heater.
