J 23600-B Belt Tension Gauge

1. Run the engine, with no accessories on, until the engine is warmed up. Shut the engine off, and read the drive belt tension using J 23600-B placed halfway between the generator and the power steering pump. Note the reading and remove J 23600-B .
2. Start the engine with the accessories off, and allow the system to stabilize for 15 seconds. Turn the engine off. Using a 3/8-inch drive breaker bar, apply clockwise force (tighten) to the drive belt tensioner pulley arm. Release the force, and immediately take a drive belt tension reading without disturbing drive belt tensioner position.
3. Using the same breaker bar, apply a counterclockwise force to the drive belt tensioner pulley arm, and raise the drive belt tensioner pulley to eliminate all tension. Slowly lower the drive belt tensioner pulley to the drive belt, and take a drive belt tension reading without disturbing the drive belt tensioner position.
4. Average the three readings. If the average of the three readings is not between 133-222 N (30-50 lb) and the drive belt is within the drive belt tensioner's operating range, replace the drive belt tensioner.
