help with timing


i have a diahatsu terios 1.3 00 reg could any one tell me what is the correct way of timing the engine during cambelt replacement as the i have accidentally lost the correct position, i can find the tdc mark on the crakshaft and line that up but how do i find the correct position on the camshaft Unknw

dont worry i have it

line up the cam shaft at 3 oclock and the tdc mark on the pully on the crankshaft is the far left edge of the timing mark.
