This is a must-have if you change your own timing belt. This is necessary to set the pulley to the correct angle and tension when installing the timing belt on a 3000GT or Stealth. You use a 1/4" drive socket torque wrench to tension the belt while tightening down the pulley bolt.
NOTE: You only need one tool - multiple are pictured. Sold individually.
NOTE2: The tool is pictured with the tensioner pulley for which it is used. The pulley is NOT included.
