How to tighten alternator belt
« on: 18 April 2012, 11:35 »
Hi,

As above really. Been pouring through this section but can't seem to find one.

The alternator is starting to go on my gti 16v. Looking to see if tightening the belt can save it or if need to get a new one. Any help or links would be appreciated!!

Alternator belt is self tightening, if its loose then you need a new belt

Thanks andy. Cam belt was done at 180k and the car is now showing 192k, should be ok I think.

Vw bush - had a look at the belt the other day. No teeth missing and no cracks in it so I'm wondering if it the alternator that's on it's way out. The battery light on the dash went out a couple of days ago. New alternator not cheap from what I've seen online.....£130 is the cheapest I've found  :sad:

Thanks for the advice guys!!!!

I'd first pull out the voltage regulator in the alternator, inspect the electrodes. If those are worn replace the regulator (unless you can find carbon electrodes somewhere).
Alternators hardly die as such - as long as bearing and free-wheel are working I'd try that first. Regulator cost approx 20£, electrodes even only around 5£...

That sounds a bit too technical for me. Not much of a mechanic I'm afraid.
