This supplement provides instructions for timing the high feature V-6 engine in various General Motors (GM) models, including the 2013 Cadillac ATS, CTS, SRX, XTS, GMC Acadia, Terrain, and others.
Preparation
Before starting the timing procedure, view videos 10208.01D and 16038.01W, and note the orientation of the injector wiring harness.
Timing Procedure
The procedure involves aligning the circular timing marks on the camshafts, removing tools, and rotating the engine. The intermediate gear for the left secondary chain and the triangular timing mark on the right intermediate gear must be aligned.
Important Notes
The procedure requires careful attention to detail to avoid damaging the engine. Specifically, do not pry against or strike the cam actuators, and ensure the injector wiring harness is properly oriented.
This supplement is intended for professional technicians and should not be attempted by a “do-it-yourselfer” without proper training and equipment.
