Alternator Problems

[Tommy B]

Has anyone ever experienced a noise problem with their alternator belt/pulley?
Mine (cup 172 52 plate) seems to sound like a diesel whilst idle, but once it's being drove it seems fine?

Any suggestions as I don't fancy the garage just yet?

Cheers in advance,
Tom

Dephaser pulley by the sounds of it, does it stop if you pick the revs up abot 1800rpm?

Yeah, sounds a lot better whilst driving but if I stop at the lights or summet it's back again.....

Any tips/suggestions or is that it "f*cked?"

Cheers

i have the same problem on my 172,when its cold theres a whining sound but once it heats up it seems to go away.worried about it packing in altogether so should i just get a new one fitted?

Definitely sounds like your Dephaser Pulley which is a Cambelt off job so will cost a pretty penny to get changed... Mine is the same but as nobody has ever stated that there is a risk of complete failure I'm going to leave mine until nearer the time of the cambelt change date again.

This sounds like the alternator is knackered as mine started whirring when my alternator was on its way out..... Best to get it changed over for peace of mind.
You can get refurbed alternators or you can buy brand new its up to you.
