Tension belt by placing a straight edge tangent to
compressor pulley and alternator. Place belt
tension tester in the center and perpendicular to
the belt between the (2) pulleys and next to the
straight edge. Push the tensioner towards the
theoretical center making sure that a deflection
force of 3.1 lbs. gets .2 inches of belt deflection at
the center of the belt. See Figures 2.12 and 2.13.
