How to replace the Cam Gear on Bank 1 (Right Side) Exhaust on Cadillac STS?

You must begin the camshaft position actuator bank 1 (Right Side) exhaust replacement work by unmounting the lower Intake Manifold for engines using upper manifold lp1 and ly7 or the Intake Manifold for engines with llc. After removing the right camshaft cover the technician must detach both the right intake then exhaust camshaft position sensors. Prerequisite action is to take out the right intake and exhaust camshaft position actuator solenoids. Derotate the crankshaft balancer bolt clockwise to position the camshafts neutrally before marking the camshaft Timing Chain and position actuators for correct assembly. Apply alignment marks to the Timing Chain links along with the corresponding teeth on both exhaust and intake camshaft position actuators. First use an open-end wrench to move camshafts together before unscrewing en-48313 (Timing Chain Retention Tool) until its legs fully retract. Place the en-48313 between the camshaft actuators where the feet point toward the engine front. Stretch its legs until they reach the Timing Chain but do not over-tighten the tool. Start by hand tightening the en-48313 followed by using an open-end wrench on the t-handle to secure the engine from turning during camshaft position actuator bolt removal. Mark the reluctor wheel opening on the right exhaust camshaft position actuator and set it aside so you can remove the bolt, actuator, and boss together. During installation process the exhaust camshaft actuator alignment mark needs to match the Timing Chain alignment mark from disassembly stage while maintaining alignment of the intake camshaft actuator alignment mark. Place the exhaust camshaft actuator onto the camshaft before installing the actuator bolt carefully by hand. Finish by removing the en-48313. Torque the right exhaust camshaft position actuator bolt to 58 nm (43 lb ft) before reinstalling the right intake and exhaust camshaft position actuator solenoids and sensors. The installation process concludes with the right camshaft cover and for llt engines includes the Intake Manifold but lp1 and ly7 engines require both lower and upper manifold installations.

How to replace the Cam Gear for Bank 2 (Left) Exhaust on Cadillac STS?
