Liamx Posted September 10, 2014 Report Share Posted September 10, 2014 Hi all,Apologies that this is my first post!After recently changing the pedal box on my daily drive Lupo (what a job...) the Auxiliary Belt decided to leave the vehicle this morning.Firstly, does anyone have a diagram for how it normally fits? And secondly, I can't seem to get access to the tensioner, is this normal?Thanks ! Quote Link to comment Share on other sites More sharing options...
Skezza Posted September 11, 2014 Report Share Posted September 11, 2014 Picking my brain, Rich is probably better to ask on this, but it's an alternator off job isn't it? Quote Link to comment Share on other sites More sharing options...
Liamx Posted September 11, 2014 Author Report Share Posted September 11, 2014 Managed to get access to the tensioner but still have no idea on the route, think it must be the only engine on the planet that doesn't have a diagram!

Skezza Posted September 11, 2014 Report Share Posted September 11, 2014 I might be able to get you an ElsaWin diagram tomorrow if you can wait? Quote Link to comment Share on other sites More sharing options...
Liamx Posted September 11, 2014 Author Report Share Posted September 11, 2014 That'd be fantastic Quote Link to comment Share on other sites More sharing options...
Kermit Girl Posted September 11, 2014 Report Share Posted September 11, 2014 Not sure if the layout is the same as on our TDI but on that it is not really possible to fit it the wrong way - it has to go over the crankshaft, camshaft and alternator and then under the tensioner roller so providing you have the correct belt and have locked the tensioner in position with a suitable drill bit then it is pretty obvious how it fits round the other pulley.

Liamx Posted September 12, 2014 Author Report Share Posted September 12, 2014 It doesn't appear that the aux belt on the 1.7SDi goes round the camshaft - it goes around crankshaft, alternator, power steering, water pump & tensioner. Really shocked there is no diagram anywhere! Quote Link to comment Share on other sites More sharing options...

Kermit Girl Posted September 13, 2014 Report Share Posted September 13, 2014 Apologies - brain fade! What I meant to say was the power steering pump pulley. Cambelt on TDI goes round crank, camshaft and waterpump. Aux belt drives all the other bits - would be surprised if the aux belt drives the waterpump on the SDI but as I say if you have the correct belt I would not think it is possible to fit it the wrong way Quote Link to comment Share on other sites More sharing options...
