There are only two timing marks one on the cam pully and one on the crank pully if you set engine to tdc then all marks will be aligned simple really if its the 1.3 or 1.6 petrol engines diesel engine best get someone who knows to do it as engine damage from a snapped cambelt is garenteed
Also if the cam belt has snapped then engine damage such as bent valves will most likely have occurred
