I bought a engine camshaft locking tool set from OMT (Orion Motor Tech ) . Pictures in the instructions are not very good for where and why to put them . I realize the 2 gear pieces fit between the cam gears , but the other pieces in the kit are pictured vaguely. Are there any how to an whys that a member has done on a 2012 chevy cruze with a kit. And also the instruction had a J 28647-B tool listed as an Engine Support Bracket . This item wasn't in the kit. Any articles on this subject or replacing the timing belt would be helpful . Thanks
