Review on COOVIE Camshaft Phaser Timing Chrysler by Erick Hernandez

The tool is cheap metal-plastic. I would buy an aluminum version if you can find it. When trying to release the tension of the timing chain, the plastic broke, and the teeth of the blocking block of the phase shifter also broke. Luckily the plastic didn't get into the internal parts of the engine. I was able to restore it. I was actually able to replace the camshaft, rocker arm and lifter without tools.
