Abstract
The present invention relates to a fan for an internal combustion engine. The fan has a locking device for a fluid friction clutch in the form of a pivoting hook that may be mounted subsequently at a fixed location using a holding device and may be triggered using an electromagnet. The electromagnet may be accommodated in the circuit of an ignition lock such that when the engine is started, the fan wheel is prevented from rotating unintentionally.
