Alright barry iv got a fiat doblo 1.9 d (non turbo), What dean said was spot on, i had mine done the other week at 80k miles. The timing kit (pulley's, tensioners and belt) for 80 odd but you should also get the water pump done because if that fails its as good as the belt snapping and it only cost 20 odd quid. I got an auto mechanic to do mine outside my house for £65
