Here is the diagram, please note that some models do not have an Air Pump (my 1987 does not), so there will be no air pump pulley. In that case the belt is a little shorter and goes straight from the idler to the Alternator and back to the Fan. This diagram is only for the M103 motor (1986-1992 - US).
