Lift the car on axle stands and remove the driver side wheel and the splash cover which covers the crank pulley. Remove the air box and the plastic cover covering the cam shaft cogs. Remove the fan belt by using a 16mm socket on the tensioner and pushing towards the rear of the car. Remove the crank pulley. (jam a screwdriver through the slot and undo). Replace the bolt from the cam shaft pulley (without the pulley) and crank the engine (clockwise only) until the marks on the cam shaft cogs directly face each other. Use a cam lock to hold these cogs in place. Release the cam belt tensioner with a torx driver and remove the belt. turn the crank (clockwise only) until the mark on the crank cog lines up with the mark on the plastic casing. Replace the belt and re-tension. Remove the cam lock and turn the engine (clockwise only) two full turns and re-check the alignment and the tensioner. Replace all parts in reverse order and you are good to go.
