    Possibly a waste of money!

    It's a pulley with an internal clutch, if the alternator is rotating faster than the belt then it disengages and reduces the drag on the engine.

    Nothing but a ball ache these, they are generally used on diesels to smooth out the engines and stop pulling on the aux belt. Had one on my corsa derv, they tend to fail every 2 years or so, make a nasty squealing noise. I changed 3 in my ownership it was practically a service item lol
