Alternator whine

drewesq · 06-09-12, 06:11 AM

I have noticed a faint whine which gets louder when I put full beam on so I am sure it is the alternator. Is this likely to be the belt or something else?

Ta!

What zs you got? Alternators always go on the k series.

1.6, so yeah it is the K series. When you say "go" do you mean needs a new one or that it just needs 'fixing'?

Get a new one mate the bearings go. it will get louder then it will die lol. I had to get one for my ZR i just found a low miles car that was breaking and it was fine but I think you can buy recon ones from eBay.. Not sure

so, are all k series alternators the same? ie. will one for a 1.8 fit a 1.6? There are a few on flea bay...

1400 and 1600 k series share the same alternator, the link from Rimmer Bros will let you work out which one you need from your vin, I wouldn't buy from Rimmers cos they're kin expensive for things like alternators.

The alternator on my 180 whines when it's hot and i'm using some power like the heated screen!! It's done it for a couple of years. It's not a sign it's about to fail imho as the noise is created by the windings ossilating however if it is worrying you then swap it just for piece of mind
