How to replace the Cam Gear on the Camshaft Position Exhaust Actuator on GMC Terrain?

The starting point to replace the camshaft position exhaust actuator starts with removal of the camshaft cover along with the spark plugs. Set the Crankshaft to receive clockwise rotation and put in the en-48953 (Camshaft Actuator Locking Tool) retention tool. The camshaft retainer bolts receive a final torque of 10 nm (89 lb in) and you should then unscrew the exhaust camshaft actuator bolt while keeping the bolt in place. Clean the Timing Chain with solvent while also labeling both the Timing Chain and camshaft position actuators for assembling the correct positions. Mark both intake and exhaust camshaft actuators on the Timing Chain before unbolting its upper guide as well as the Timing Chain Tensioner. Place the en-48749 (Timing Chain Retention Tool Kit) retention tool on the exhaust Timing Chain side before you remove both the exhaust camshaft actuator bolt and the exhaust camshaft actuator which must be discarded after separating it from the Timing Chain. Install the Timing Chain in the proper position onto the exhaust camshaft actuator after aligning its intake camshaft actuator alignment mark with the Timing Chain mark. Secure the intake camshaft actuator onto the camshaft by aligning its mark with the Timing Chain mark then tighten it using a new exhaust camshaft actuator bolt until undergoes adequate tightening. Use a retention tool en-48749 to remove from the exhaust Timing Chain location and install the tensioner along with resetting it followed by retainer installation of the intake camshaft actuator then tighten bolts to 10 nm (89 lb in). Use en-45059 (Angle Meter) to torque the new camshaft actuator bolt to 30 nm (22 lb ft) while additionally rotating it by 100 degrees. You should torque the Crankshaft balancer bolt counterclockwise at 45 nm (33 lb ft) to release the tensioner after removing the en-48953 retention tool. The last step is to install both upper Timing Chain Guide assemblies with 10 nm (89 lb in) torque. Next install the camshaft cover and spark plugs.
