The fan - fan pulley
like to check the water level in your 2CV's radiator - you will have a
hard time. As you should know, the 2CV motor is air-cooled. The cold
air streams alongside the cylinder head and cylinder walls and
transports the heat away. To supply enough cooling, the air stream
supplied from the movement of the car is insufficient. Even in hot
summer temperatures and standing still in a traffic jam, the motor may
not overheat. To supply this air stream the motor has a fan on duty.
The plastic fan is attached to the front end of the crankshaft. While
the motor runs the fan supplies the essential cooling.
Picture 1 Fan pulley with crack
crack appears it will be visible by a fine rusty line alongside the
crack. The fan pulley is zinc plated in yellow. Rust will develop in
the crack on the unprotected surface. The fast rotation of the fan
pulley will drive the water out of he crack. The rusty red water will
go from the crack to the outside of the pulley. You can clearly see
the traces. The crack itself is the sharp borderline between the clean
inside and the rust red outside.
