This engine tool is a must-have for any automotive enthusiast! As a result of using this product, I FOUND that it securely locks the camshaft in place, aiding in the installation of new timing belts or chains. Its sturdy design and compatibility with various engine types make it a versatile tool for any mechanic .The only downside is that it can be a bit tricky to adjust to certain engine configurations. Overall I highly recommend the GOGOLO Engine Camshaft Locking Compatible tool for anyone looking for a reliable engine tool..
