Use a 32mm spanner put it behind the fan. Then hit the spanner, a few short beats with an hammer TO THE RIGHT!!!It's a left hand thread. If the fan is released you can turn it manually. But take care for the thermostat-shell. Don't damage it by hammering on it with the spanner.

The fan blade will break on a 94 BMW 325i if an object has falling into the fan. This will cause the blades to strike it at high speed and shatter.
The temperature sensor on a BMW 325i is located on top of the engine, near the upper radiator hose. It constantly monitors the temperature of the coolant and triggers the cooling fan as needed.
If you mean the HVAC fan, the resistor should be located within the fuse block.
how to remove the clutch fan on the 530i bmw
you need to remove the fan the thermostat and the thermostat housing, and the water pump pully and belt. Also you will need to remove the radiator hoses, these should be checked for any holes and replaced if needed.
Everyone of my blades broke yesterday on my 95 325i. Looks easy to fix. No idea as to why they broke. I have not found a logical answer to this problem as of yet.

how do you remove the fan clutch on a 1992 318i 1.8 liter?
To change out the blower motor in this car disconnect the battery ground and then carefully remove the long plastic cover that is mounted in the engine compartment at the top of the firewall. The blower motor is easily accessed as is the resistor board below it for the lower fan speed selections.
The fan is attached to the fan clutch at the front of the engine. It is held on by one very large nut (I think it's 32mm). Usually you will need to remove the plastic fan shroud first. The difficult part of this is that the nut holding on the fan is a reverse thread, the opposite of what you would expect it to be. You turn it clockwise to loosen. Also, you might need a special tool (Google "BMW fan clutch tool") to hold the fan clutch and keep it from turning when you remove the fan.
the thermostat is inside a black plastic housing, it is inside the housing assembly where both radiator hoses meet up by the engine. one cannot replace just the thermostat, the whole housing has to be replaced, good luck. For easier access, remove the fan assembly (just one allen-bolt on the passenger side and a plastic rivet on the driver side).
after you remove the fan and fan hood remove the belt and the alternator. you then remove the 6mil bolts and your water pump should come free from the timing chain cover.
