Alternator squeal

[mickeyw]

Hi Guys. I`ve got a 2003 Galaxy TDCI with a noise which I believe is the alternator as when I use anything that needs power like lights or electric windows it gets louder. What should I look for first to get it fixed?

Thanks in advance for any help with this.

Tighten the alternator drive belt and the noise will disappear as if by magic.

or get a Electrical Trainee to look at it. you'll be told that the engine is obsolete and doesn't comply with current regulations and so will need to be replaced at a cost of £3000.

Cos it says so on his new plug in diagnostic equipment.

Could be belt failing,drive clutch,on alternator (if fitted),or worn/seized tensioner.

Have it looked at before that expensive taxi ride...:yes:

Unless it's noticeably loose, first stop would be to just fit a new belt. If you overtighten belts it causes premature bearing failure on the pulley shaft bearings so always rather go a smidgen loose with a belt than too tight if you don't have a tension checking gauge tool.

thought you used elephant gut for fan belts in SA. :38:

I believe the tensioner is automatic and it will be weak (a pully with an integral spring) a new belt will fix it for a short while

Here calm your beans man. The post (admittedly in the wrong section) is based on an alternator which, last time I checked, is somewhat relevant in our sector

And it's replies like yours that is making this forum the way it is!

Check the alternator pulley they are a freewheel type and can cause the problem you have when they fail. They normally seize and are not repairable my brothers have replaced a few on the Galaxy / Sharan / Alhambra vehicles they have. Problems with the pulley are also noticeable when driving the vehicle when you lift of the accelerator in normal driving
