Nissan Terrano ll 1996 2.7 tdi (Mistral) - ACC Drive belt adjustment - AndyA131

Hi everyone. I have just adjusted (Tightened) the top two belts on my Terrano by using the adjustment slides as usual but I can only see one long headed bolt on top of the ACC belt pulley. Is there any other nut that needs to be loosened before I tighten this long bolt down thus bringing the pulley up in its slide? Any help would be much appreciated. Many thanks.

If I recall ,you need to slacken the guide pulley centre bolt/nut ,adjust the bolt tensioner ,then re tighten the pulley fixing.
