Electric fan issues

[Simon Wallwork]

My early FL S8 sometimes makes a right racket shortly after start up.

I isolated the racket as coming from the electric fan.

First query: Why does this fan run on startup? The engine is plainly stone cold.

I found that the racket went away after 10-20 secs most times. Also noticed that it was rarely a problem if I was in the car alone but it was a lot worse with pass seat occupied. Also, slamming a door or lowering the bonnet would start it. Or stop it!

Anyways, last night it got worse and eventually did it most of the time.

Solution: Today, when it was constant, I noticed that the leccy fan shroud was in less than perfect register with the part of the front panel that it's mounted on. If I squeezed it with my fingers, I could stop the noise.

I got a cable tie through the gap between the blade tips and the shroud and tied it off against the ally piece that forms the landing panel for the bonnet.

This brought the fan shroud in to the front panel much more tightly and stopped the racket.

I could've changed the fan assy, and might yet have to. Cheap fix tho.
