• Q: How to replace the Cam Gear on the Camshaft Position Exhaust Actuator on 2010 Chevrolet Cobalt?

  A: First disconnect the camshaft cover along with all spark plugs before initiating the camshaft position exhaust actuator replacement process. The Crankshaft should rotate clockwise while you install the camshaft actuator retainer (EN-48953). Attach the camshaft retainer bolts at 10 nm (89 lb in) before releasing the exhaust camshaft actuator bolt but leaving it untouched. Rephrase the following sentence. Clean the timing components with solvent as you clearly note the positions of the Timing Chain and camshaft position actuators for proper final assembly. Apply markings on the Timing Chain to identify positions of both intake and exhaust camshaft actuators. Dismantle the upper Timing Chain guide bolts first along with the guide before proceeding to remove the Timing Chain Tensioner under conditions which prevent camshaft actuator rotation during uninstallation and reinstallation. Use the Timing Chain retention tool (EN-48749) on the exhaust side to perform the operation then discard both the exhaust camshaft actuator bolt and the exhaust camshaft actuator from the camshaft. To install the Timing Chain position it on the exhaust camshaft actuator before aligning the mark on the actuator with the chain while securing a new exhaust camshaft actuator bolt with proper torque. Set the exhaust camshaft actuator alignment mark to match the Timing Chain precise position. Set up and install the Timing Chain Tensioner before the installation of the Timing Chain retention tool (EN-48749). The intake camshaft actuator retainer requires 10 nm (89 lb in) torque for its two bolts while the fresh camshaft actuator bolt requires 30 nm (22 lb ft) torque followed by 100 degrees additional torque obtained from the angle meter j 45059. Free up the tensioner through counterclockwise rotator torque of 45 nm (33 lb ft) applied to the Crankshaft balancer bolt followed by removing the camshaft actuator retainer (EN-48953). The procedure ends by tightening the upper Timing Chain guide bolts to 10 nm (89 lb in) and then installing the camshaft cover and spark plugs.
