Depending on the engine, the coolant temperature in a Cadillac could be from 180 to 195 degrees. The thermostat can be changed to give a lower or higher temp reading.
It depends on which model year / engine. The E46 330i operating coolant temperature is about 97 Celsius.

I am an ASE certified technician. Your normal engine or coolant temp should be 190 - 210.
In all probability you either have a bad radiator cap or an air lock.
The fan only runs when needed to help cool the engine. The engine coolant sensor or a separate engine temperature switch is used to monitor engine temperature. Extra cooling is not needed when an engine is first started, so the fan does not come on until that engine reaches normal operating temperature which is usually from 195 to 215°F. The fan will then cycle on and off as needed to maintain the coolant temperature. So the fan runs mostly at idle or low-speed when the engine is at normal picture.
Below 220 degrees .
Generally speaking, it should not get any hotter than the normal operating temperature of your engine coolant.
