Hi folks
The alternator belt on my 2004 mazda 2 1400cc petrol car went the other day. I got 2 new belts - one for the alternator and one for the power steering. When I came to mount them I cannot find anyway to slacken the pulleys in order to mount the new belts. There are no belt tensioners and no adjustment on the alternator. Anyone got any good ideas please. I've attached a sketch of the setup -

Thanks
Andy
