How to replace the exhaust camshaft and lash adjuster on Chevrolet Cobalt?

Begin exhaust camshaft and lash adjuster replacement operation by removing the exhaust camshaft position actuator. Detach each bearing cap bolt by turning it one revolution while marking the bearing caps for later use in proper reinstallation. The necessary steps start with bearing cap bolt extraction followed by bearing cap removal and exhaust camshaft extraction from the system. Separate all components of roller followers and hydraulic adjusters for reinstallation and afterward take out camshaft roller followers, hydraulic adjusters. Place the hydraulic element adjusters inside their bores in the Cylinder Head while applying gm pn 12345501 (Canadian PN 992704) or equivalent lubricant to both adjusters and valve tips. Used roller followers need to maintain their original position on the camshaft during installation. When the camshaft requires replacement it means you need to replace the associated roller followers which operate with it. Working with the same lubricating material transfer the roller followers onto the kale stem tip and lash adjuster. After lubricating the exhaust camshaft you should install it while tightening all bolts on the bearing caps by hand. To complete the repair stage you should first hand-tighten all bearing cap bolts before expanding the torque to 10 nm (89 inch lbs.) through alternating bolt movements of 3 turns. Reinstall the exhaust camshaft position actuator afterward.
