Hi there and welcome to Renault Forums, as far as I am aware the auxillary belt should be positioned on the offside of the pulleys leaving a slight gap on the engine side, is something not working correctly?
Hi again, this is a very rough diagram of the belt setup with aircon, If you have a look on your engine if you see the pulley marked 'G' in the diagram then this will be the correct one for your engine. If not Get Back to us and I'll draw out the one without air con. Hope this helps.
I have drawn my setup next to yours. Although the layouts are very different :crazy: the pulleys still all go the right way (small mercy) but I assume that if the length for the proper setup (yours) is longer than my setup that would explain why my belt is slack and the tensioner can't take the slack up.
I think I can fix it now. Thanks very much for your help.:d
