guides on changeing dturbo alternator tensioner?

[Tom]

Drivers wheel and arch liner out and you can get at it easy enough. Then theres a 6mm allen bolt in middle of the pulley then another 6mm allen headed bolt half way down the tensioner. Then theres one on the bottom facing up which controls the tension, so you'll need to adjust that first to slacken the bolt. but the top 2 need to cracked off aswell so the tensioner can move. If any of that makes sense. Once you see the thing it will!
