1Application: Fit for the engines 1996 and later: 3.0 V6, 3.3 V6, 4.0 V6, 4.7 V8. also 4 cyl; 1983?1995 22RE; 1995?2004 2RZ; 1995?2004 3RZ; 1990 and later and 3.0 L6, 3.0 V6, 3.3 V6, 4.0 V8, 4.3 V8, 4.7 V8. 2Keep Crank Pulley Still: During the removal and setting of the final torsion specification on the pulley bolt, prevent the harmonic damping pulley from rotating, so that the user can easily remove and install the crank bolt. 3Thin and Light Design: The damper pulley holding tool is small enough to access and remove the harmonic damper pulley without removing the radiator or other components, 4Precise Fitting Hole: The hole in the center of the tool can be used to remove the crankshaft bolt. Users can hold the crankshaft when tightening the crankshaft bolt with a torsion wrench. 5High Efficiency: Factory specifications require up to 280 pounds of torsion, the tool allows easy removal and replacement of crank shaft bolt to factory torsion specifications.
