i have a renalut clio 1.2 how do i set my tracking

Oh dear, there is a possibility of valve damage, hopefully not. you will need to remove the timing belt cover. On the camshaft sprocket you will need find an indentation this should be in the 12o'clock position, on the crankshaft sprocket as you look down you will find a cut out on the washer behind the sprocket this should line up with a cut out in the casting just below the sprocket. once you have fitted and checked the marks are aligned turn the crankshaft clockwise two revolutions until the marks are aligned. Hopefully once all fitted up she will start.
