A tensioner for an engine accessory drive system includes a tensioner arm pivotally mounted for movement between a free arm position and a load stop position. The tensioner arm includes a pulley which engages a belt. A piston, disposed in a cylinder, is pivotally linked to the tensioner arm. A spring urges the tensioner arm towards the free arm position. A moveable load stop member, controlled by an actuator, projects into the cylinder. The load stop member abuts the piston to thereby arrest movement of the tensioner arm and define the load stop position. The actuator may drive the load stop member against the piston to move the tensioner arm towards the free arm position so as to increase belt tension.
