Bracket is used to hold a GM 1.5L engine. Bracket is installed onto both camshafts, and holds the assembled hex on both cams to maintain their relationship during timing chain, actuator, camshaft and valve service. When cylinder #1 is at TDC, install tool onto both camshafts to hold, and prevent chain jump when actuator bolts are removed or installed. Also use when the timing chain is replaced, and re-establish the cams in the correct position after camshaft or valve service. Applications: Buick Encore 2016-2017, Chevy Cruze 2017, Malibu, Trax, & Volt 2016-2017. Compare to GM Factory Tool #EN-51367.
