Slacken tensioner centre bolt .now under alternator the tensioner adjusting bolt is well hidden I get a 12 mill socket knuckle joint Long bar and go through the holes in the front grill bit fiddly. or hand in under alternator but it's tight on space MAKE SURE YOU GET THE GROVE IN THE BELT ON RIGHT I can do pics if you like .
