Constant Whineing Noise

7 posts in this topic

My car has developed a whineing noise, and i am 99.9% certain its coming from alt as done the trick with screaw driver on alt and ear to screaw driver., when i first start car a squeak can be heard coming from belt end of engine, this has allways done this, but whineing noise only happened 2 days ago.

A mate said he can change bearing in alt and this will solve it, saves buying new alt.

By the way it's a 2.0 zetec. 2000.

Is changing bearing an easy job.

and is it worth changing anything else whilst alt and belt is off.

Its just ticked over to 150 thosand miles.

Good idea, be careful not to get WD40 on the belt.

Tempted to say, check it's not the other half making the whining noise. :D

If it is the alternator bearing there is a risk of it breaking up or seizing so I wouldn't hang about getting it fixed

it was not the alt, it was alt belt tensioner pulley, tried all motor factors, they all only sold the full tensioner not just pulley, so I temporary put one on from a scrap car, untill i can source a new pulley wheel, car is nice and quiet again.
