Hi there, just wondering how you managed to tension your a/c pulley when you put the new belt on. Are we meant to lift the pulley up with a lever and then just tighten the allen nut. Seems odd then there is no toothed guide to make tension. I noticed the a/c has a nut that has a 17 on it and was wondering if that might shift the a/c to tension. Any thoughts would be great.
Thanks Sam

Sam,

I use a 7/8" wrench or adjustable wrench to fit on the end of the arm of the tensioner, then loosen that 17mm bolt that secures the arm to the engine and lift up on the arm. Hold the desired tension and tighten the 17mm. The allen nut isn't involved.
