This tool is placed in between the belt tensioner and the water pump pulleys
Then, by slowly turning the tools inner nut, pressure is applied to the hydraulic tensioner pushing it into a position that allows the technician to place supplied locking pin into the hydraulic piston push rod
Once the licking pin is in place the tensioner compressor can be removed and the timing belt placed on all appropriate pulleys
After the belt is placed on the engine pulleys, the locking pin can be removed to return tension on the timing belt
Replacing the timing belts on 5VZ-FE, 3.4L V-6 and 4.0L, 4.3L, 4.7L V-8 engines is a very difficult task. The professional technician has no means to effectively compress the hydraulically activated belt tensioner without spending additional time removing engine components. This tool is the answer to this problem.
