There are several recommendations that say you should replace the water pump, hoses, and thermostat at that time too.

For the E36/E46 models which have known cooling system issues. Recommendations for those models:
Water pump: 60K
Radiator: 100K
Hoses: 150K
Not enough data for E9X series to determine a trend of failed cooling components, so any recommendations at this time are just guesstimates... I obviously think 100,000 miles is too soon for these components.
