Anyone throw any light on this one.

The wifes T reg Fiat Punto S has started making a high pitched whining noise between 2500 and 3000 rpm. Seems to do it more "off load" (ie driving down hill). However it seems to disappear when the car is warm and sometimes doesn't do it at all. It's not a particularly loud noise, almost seems like its coming from inside the car. I've checked the usual places - radiator fan, fan belt etc with no luck.

Anyone else come across this one ?

if you take the wife out does the whining stop? Sorry, just couldn,t resist it.

out of the car.

Thanks Ray,

I think I can safely say (looks over shoulder) that this whine is nothing to do with the wife !

I had a heater blower fan that whined when cold but not on hot (until it destroyed itself). But being on/off load shouldn't make any difference there.

Don't s'pose you could record an mp3/wav and post it? Sounds worryingly as if it could be gearbox/diff related Does it do it when stationary?

p.s. I was also tempted by the wife gag, but alas too late

been using my girlffriends punto for work, that does exactly the same, only when cold around 3k, almost sounds like a supercharger!! goes off when it's warm. if anyones got any help that'd be great, put me in good books after spending most of the weekend in the pub!!

Kev, just rev it harder and stay in 1st and 2nd

cam belt tensioner?

yeah good idea leigh, don't think she'd be too impressed!!! have you workrd out how to download pics leigh if not e-mail em me and i'll stick em on!

sounds like the belt tensioner,they are a doddle to change and only a few quid

Won't a bit of wd40 do the trick

Probably worth changing the timing belt as well ? have known tensioners to sieze on these and cause belt failure

hang on a bit ,wheres my pat on the back i said it first!

sorry Froggy, my fault for rushing through the post. (hope I didn't offend you)

thanks for your help

My mates punto was doing the same, Then the cam belt snapped (whilst I was in the car) I believe it was the tensioner, the AA guy said it wasnt uncommon with fiats.

I know exactly what the problem is, you need a louder stereo!!!!!!!!!!!!!!!!

the louder stereo trick only works on company cars

You will not need the louder stereo when the timing belt fails , Thre will be no whine.
