A timing tool kit for GM 2.0L LSY and 2.7L L3B engines, used to hold the actuators and flywheel in their timed positions while the oil control valves, camshaft actuators or timing chain are serviced. The actuators must be held in place so the valves can be removed and installed, and the tools also take up slack in the timing chain before that work begins.
The kit includes a tensioner retention tool, a camshaft torque reaction tool, a camshaft alignment tool, and a flywheel locking tool that installs in place of the starter. The listing names the vehicles covered, from several CT, XT and Silverado or Sierra models to Colorado and Canyon. Users should retract the timing pin before torquing any fasteners, because torquing with the pin engaged can damage it.
