The auxiliary belt tensioner is located just behind the crankshaft pulley: to remove it, first loosen the tensioner to release the belt and the various pulleys (it's easier with the engine suspended from a hoist); once the auxiliary belt is removed, the tensioner is secured to the block with a pin: simply unscrew it to extract the tensioner from its seat; during the installation of the tensioner, align it with the centering notch on the tensioner itself in the designated groove.
