indie Posted November 16, 2015 Report Share Posted November 16, 2015 Hello guys,Does anybody know if Lupo gti alternators use a clutch pulley, or not?I have a weird noise coming from that end of the engine when cold (not present with aux belt removed).Sounds *a bit* like this: Spoke to my local VW place today, they recon that some alternators that fit the gti do have a clutch pulley, some don't...My pulley turns the alternator both ways, so its either a knackered clutch type, or if its not a clutch type the problem is not the alternator Any help appreciated.

indie Posted November 16, 2015 Author Report Share Posted November 16, 2015 I guess it could be either - car has AC.The alt clutch just seemed like the most likely culprit, but nobody seems to know for sure if the Lupo gti alternator has a clutch type pulley - or not.

indie Posted November 28, 2015 Author Report Share Posted November 28, 2015 As it turns out, my GTI doesn't have an alternator clutch - although many Lupo's do. Has anybody tried to change the tensioner pulley using one of these spares? http://www.ebay.co.uk/itm/VOLKSWAGEN-JETTA-LUPO-BEETLE-Fan-Belt-Tensioner-Pulley-V-Ribbed-Belt-Idler-/141810778750?hash=item210494c27e:g:FGUAAOSwo0JWLDXs Quote Link to comment Share on other sites More sharing options...
