Re: Auxiliary belts
You actually need to buy 2 tensioners, 1 fixed and 1 moving one. Thats providing your car has aircon, as most 156's do.
The best bet is to remove the cover under the wheel arch, and the one on top of the belt that is fixed to the cam cover, and have a look to see where the belt goes, its quite a complicated route. You will also need a swan neck 15mm ring spanner to undo the nut on the fixed tensioner. A normal spanner will not do, and there is not a lot of space for a socket.
You will never be cool driving a Vauxhall.
