Tension Check

Run engine, with no accessories on, until the engine is warmed up. Shut the engine off and read belt tension using J 23600-B placed halfway between the generator and the power steering pump. Note reading and remove J23600-B.
Start the engine with the accessories off and allow the system to stabilize for 15 seconds. Turn the engine off. Using a 15mm socket, apply clockwise force (tighten) to the tensioner pulley bolt. Release the force and immediately take a tension reading without disturbing belt tensioner position.
Using the same wrench, apply a counterclockwise force to the tensioner pulley bolt and release the pulley to eliminate all tension. Slowly lower the pulley to the belt and take a tension reading without disturbing the belt tensioner position.
Average the three readings. If the average of the three readings in not between 225 and 315 N (50 and 70 lbs.) and the belt is within the tensioner's operating range, replace the tensioner.
