Drive Belt: Component Tests and General Diagnostics
Belt and Tensioner Load Inspection
NOTE: The following procedure is to be used when the belt is suspected of allowing pulleys to slip or causing any unusual belt noises.
1. Warm up the engine for approximately 10 minutes with all accessories turned on. The steering wheel must be turned full left and right several
times, if equipped with power steering.
2. Shut the engine off.
3. Using a 14 mm or 9/16 inch wrench, depress the tensioner arm until the belt becomes loose on the pulleys. Slowly allow the tensioner to apply
tension back on the belt.
NOTE: A Snap-on tool S8190A (or equivalent) wrench can be used to easily access the tensioner release bolt.
CAUTION: The marking on the tensioner arm must fall within the operating range (two marks) on the tensioner body. If the tensioner marks fall
outside the operating range, the accessory drive belt must be replaced. The tensioner pulley must not be allowed to snap against the belt.
