CAUTION: When installing the serpentine accessory drive belt, the belt MUST be routed correctly. If not, the engine may overheat due to the water pump rotating in the wrong direction.






2. Install new belt. Route the belt around all pulleys except the idler pulley (5). Rotate the tensioner arm until it contacts it's stop position. Route the belt around the idler (5) and slowly let the tensioner rotate into the belt. Make sure the belt is seated on to all pulleys.
