    I'm getting a squeak from the aux belt area so I'm suspecting either the tensioner or the alternator to be the culprit.

    Are there rebuild kits available for the alternators on these vans? (54 plate 1.9 di). Can someone point me to what I might need?

    Could be your freewheeling decoupler pulley on end of alternator shaft , see if it's got any sideways movement by running engine & shining a torch on it . These pulleys have been known to fall off the shaft at high speeds & bounce around the engine bay of many a car smashing through cam belt covers & causing major damage . Squeaking is usually the first sign it's on the way out.

    Its not the fan belt squeaking is it, they used to do that a lot. if it does it as idle squirt some water or wd 40 on the belt and see if the noise stops from Fred in Essex.

    The squeak goes away if I give it any throttle at all. It also disappears at idle once warmed up.

    My plan was to squirt pulleys individually with wd40 to isolate the culprit. I just need the van to get through the week as I'm using it to move house and can't work on it till after.

    Ok yes if you put water on the belt or wd 40 on the belt itself and it stops them it's the fan belt that's causing the problem, you would e surprised how bad a noisey belt can sound, it can sound like the water pump bearings have gone, just a little squirt and all the noise disappears...we used to chalk the belts or put a new one on, sometime they can even be loose and screech from Fred in Essex.

    To stop belt squeaks use talcum powder or ground chalk .

    Thanks guys. I sprayed a little bit of water on the ribbed side of the belt and the squeak disappeared.

    I changed the belt as a precaution but noted the tensioner pulley was noisy. I'm going to change it next week. Thus may have been affecting the belt tension causing the squeak.

    The alternator pulley seemed quiet and smooth so I'm going to leave that for now.

    Surprised I can hear anything over the noisy gearbox on this van!
