Just in case it's not clear from above, there are three belts on the fto.
1. The timing belt, also referred to as the cam belt.
2. The alternator belt (referred to by your mechanic as the fan belt). I would have referred to it as a fan belt also
3. The air con/ power steering belt.
As Steelroe siad you can pick up the gates belts in your local motor factors. Funky product and camskill should also have these belts.
