hii,iv just took the alternator off my 2004 c5 hdi 2l and phones the parts shop up and they want 150 quid including exchange which i think is rather expensive,but also locationg a used 1 seems to be difficult,does anyone know if its the same part as the xantia or xsara,it is the 150amp 1 which makes it more expensive,cheers,andy

I believe the C5 alternator has a freewheel, which is what makes it so expensive. Exactly why anybody would want a freewheel on an alternator is beyond me.

I guess the freewheel is there to enable it to disengage when it's not needed to work hard or, maybe so that it does not overspeed at high revs and therefore unnecessarily sap power from the engine; a bit like the old viscous cooling fans...

It does seem a bit OTT, like Dual Mass Flywheels
