Belt Tension
The serpentine belt is tensioned by an automatic tensioner. The tensioner is located on the front of the engine, below the power steering pump. The tensioner is spring-loaded and applies tension to the belt as it wraps around the pulleys.
To check the belt tension, use a belt tension gauge. The gauge should be placed on the belt between the crankshaft pulley and the tensioner pulley. The tension should be between 220 and 280 pounds.
If the belt tension is too low, the belt may slip and cause the engine to overheat. If the belt tension is too high, the belt may break and cause the engine to seize.
To adjust the belt tension, loosen the tensioner pulley bolt. Then, use a pry bar to pry the tensioner pulley away from the belt. Once the belt is loose, adjust the tensioner pulley bolt until the belt tension is correct.
Once the belt tension is correct, tighten the tensioner pulley bolt.
