BELT ROUTING
Refer to Fig. 16 for routing of serpentine drive belt.

TENSIONER INSPECTION
1. Run engine, with no accessories on, until normal operating temperature is reached. Turn engine off and read belt tension using belt tension gauge tool No. J-23600-B, or equivalent. Place gauge halfway between alternator and power steering pump.
2. Start engine, with accessories off, and allow system to stabilize for 15 seconds. Turn engine off. Using a 15 mm socket, apply clockwise force to tensioner pulley bolt. Release force and immediately take a tension reading without disturbing belt tensioner position.
3. Using a 15 mm socket, apply counterclockwise force to tensioner pulley bolt, raise pulley to eliminate all tension. Slowly lower pulley to belt and take a tension reading without disturbing belt tensioner position.
4. Average three readings. If average is not between 50-70 lbs. and belt is within tensioner's operating range, replace belt tensioner.
